As long as we produce agricultural products, I think everyone has the same desire to produce delicious vegetables, that is, agricultural products. You shouldn't want to go out of your way to make something that tastes bad.
What is delicious, what is the scientific basis, put aside a little difficult things,
There is certainly such a thing as "delicious vegetables". Although it is very rare that it is the most delicious, I think that if it is normal and delicious, it is relatively common.
In the past, in joint research with a research student at a nutrition university, we measured the numerical values of various nutrients, and at the same time conducted a taste survey on humans. It can be said that vegetables that many people find delicious are generally highly nutritious.
I will write down the very basic conditions for deliciousness that I think. I think it depends on the items and conditions, but I arranged them in order of importance. This is a vegetable based concept. Regional things and tasteful taste are removed this time.
1.Cultivate in an environment suitable for plant physiology.
2.Season (best time to eat)
3.Freshness
4.Variety
5.Cultivation management
You may say that it is a matter of course, but in order to make delicious vegetables, it is important to think carefully about the conditions that make them delicious. It is often used in cultivation management. Of course, I think that ideas to make delicious things will also be born from there.
1. Right place, right crop
Needless to say, if you don't plant it at the right time, you won't get good results. After all, vegetables that are grown in the right place, suitable for the climate conditions, and grown in the environment that the vegetables like are delicious, and there are few losers. For management, it has become commonplace to grow under conditions that are not suitable for the off-season.
The easiest way to understand this is to know the origin and characteristics of the vegetables you are growing. You can use the place of origin and characteristics of the vegetables you are cultivating for cultivation management. I highly recommend that you check it out. In some cases, it may be possible to choose a new product that is more appropriate for your area.
It doesn't matter which region is suitable for the growing season, but a large temperature difference is very advantageous for making delicious food. The reason why a large temperature difference is advantageous is that the amount of respiration at night decreases. This is because the cooler the nights are, the less sugar is consumed during the day because the amount of respiration is reduced.
In the case of tunnels and greenhouses where the temperature can be controlled artificially, rather than warming it up, managing it with a feeling of lowering the night temperature will make a big difference. The difference in the products produced by this difference in temperature control is very large. After all, since it is a daily occurrence, even a slight difference in temperature during the growing period appears as a considerable difference. However, this does not mean that the daytime temperature should be raised. If the growth temperature is exceeded, the amount of sugar produced by photosynthesis will be exceeded and respiration will become intense, which will have the opposite effect. It's all about the right temperature range for growth.
2. Seasonal items (the best time to eat)
Well, this is also natural. Suitable for the right crop and seasonal. It's no match for this. It's the easiest to make and the most delicious. However, the meaning of the season has two meanings: the seasonal season and the season in the sense that it is ready to eat. It goes without saying that it is seasonal, but people do not understand that it is the best time to eat.
Less understood is the "immature" one. Immature refers to all leafy vegetables, and most fruit vegetables are harvested in an immature state. There are vegetables that are harvested at different times than they are delicious. There are many other vegetables that become unpalatable as they grow larger, and the right time for delicious vegetables and the right time for the size you want to ship may differ.
This is also related to freshness. It is said that modern vegetables are less nutritious than those of the past, but this is not necessarily the case due to differences in measurement methods. It is said that the nutritional value of vegetables has declined because of the fact that annual cultivation is being done so that there are vegetables all year round, and that the nutritional value of vegetables is low due to the fact that they are being overwhelmed by low nutritional values outside of the proper season. In any case, it can be said that there is a high possibility that the nutritious value will be high if it is harvested in the right place and when it is ready to eat.
3. Fresh
This is by far the best when fresh, with the exception of some items that are better stored.
What you need to be careful about here is that if you don't eat it yourself, it's delicious if it stays fresh for a long time. It's natural that it tastes good right after it's picked, and if it keeps well for a long time, it's highly likely that it will be delicious the next day or even the day after that.
In other words, customers will not feel that the food is delicious unless it is fresh for a long time. The producers eat the fresh ones, but the customers eat the ones that are a few days old, so this is an important point.
As I wrote before, longevity depends on the internal quality. Generally speaking, plants that tend to have high nitrate nitrogen content do not last long. Also, even if there is not a big difference on the day of harvest, the difference in taste will increase the next day and the day after that. I guess.
If you are like me and measure the same crops from different fields, the difference is obvious, but many people have never seen such a difference. It might be even more interesting if you compare them among your friends, but it's scary because the superiority and inferiority will become clear. Therefore, nitrogen control is important to keep freshness for a long time.
4.Variety
A delicious breed has a lot of characteristics, and it is often a breed that is difficult to grow. I wonder if it's okay to write such a rough thing, but it's generally recognized as such. The reason why it is difficult to grow is because many of them are sensitive to fertilizers and the environment.
Recent selection of varieties tends to prioritize disease resistance and ease of production rather than taste, so it is generally not very popular. So, I think it's best to ask the manufacturer when choosing a variety.
Also, tastes vary greatly depending on the customer, so it may be important to select varieties according to the customer's demographic.
5. Cultivation management
I think that many people are thinking about the pursuit of deliciousness in cultivation management, but the pursuit of deliciousness in the true sense of the word has a greater weight as an influencing factor.
You can see how disadvantageous it is to produce the right crop at the right place and at the right time in the wrong place and at the wrong time of year. Therefore, this is the basics, and it is very difficult to make a difference in taste in a disadvantageous place compared to an advantageous place.
Freshness is important, but if it doesn't keep well for a long time, it will be unpopular with customers. In that case, cultivation management is important, but the current situation is that many people do not know what is necessary to improve the shelf life.
In order to make the most of the variety, it is necessary to match the cultivation management to the variety, but it is quite difficult to overcome the differences of the varieties and bring out the difference in taste.
There is no difference between organic farming and conventional farming in cultivation management, both are the same. The reason is that the other party is a plant, and it does not matter whether it is a chemical fertilizer or not. If the conditions for producing delicious food are met, delicious food can be produced, but if the conditions are not met, it will be unpalatable.
Now, let's put the order of importance for cultivation management on our own.
1) Uniformity(aligning)
2) control nitrogen
3) Grow root hairs
<4) Increase the temperature difference>
1) Uniformity(aligning)
You may wonder what is related to the taste, but the fact that the size is not uniform means that the growth is uneven, and the good ones and the bad ones are mixed. Good food will taste good, but bad food won't, so it won't taste good. People who lose will only think that it was bad.
I mentioned this last time about aligning, but it's the basics of the basics. If you don't have it, it's impossible to pursue deliciousness.
Good matching depends on various conditions.
2) control nitrogen
This has two meanings. One is the control of nitrogen up to the early stage (after the main plant is deployed until the roots are well established) and the nitrogen during the reproductive growth period or harvest time.
Controlling nitrogen in the early stage means that it is better to keep nitrogen in the soil as little as possible until the roots are well-stretched. This is because if there is a lot of nutrients in the soil, the roots do not need to grow and the roots do not spread well. Poor root tension is definitely not a good thing, so it is better to have as little nutrients as possible until the actual deployment. Initial growth is poor with such nitrogen control, but this is not a problem. Early growth is now considered very important, but it is wrong. In the early stages, root growth should be emphasized over leaf growth.
This is the difference between conventional cultivation and so-called organic cultivation, which does not use chemical fertilizers. When chemical fertilizers are used, the fertilizer is applied before sowing, which inhibits root growth during the most nutrient-rich period of the growing season. If chemical fertilizers are not used, the amount of nitrogen will gradually increase in proportion to the decomposition rate of organic matter. . In other words, in order to close the difference between conventional cultivation and the case of not using chemical fertilizers, there is a high possibility that we will lose a little if we do not devise this part. Conversely, if this part is cleared, the big difference will disappear. Of course, other management differences are also involved, so it cannot be explained easily, but from the perspective of management technology, the difference is that point.
Nitrogen control during the reproductive growth period or harvest time is unnecessary because, as I wrote in the section on longevity, the longevity will be poor if nitrogen is not controlled. It will be difficult to make delicious things. In the case of leafy vegetables in particular, the impression that they are grown with chisso is strong, so there tends to be a lot of chisso. The fact that the plant does not grow without nitrogen at this time is particularly likely to occur if the roots are not well-stretched in the early stage, and it may be better to think that it is combined with the above-mentioned suppression of initial nitrogen.
It's not just a matter of having less nitrogen, it's a matter of balance for plants.
3) Grow root hairs
Root hairs are small, invisible roots. It is this root hair that is always written as rooting.
It is necessary to reduce the initial nitrogen, which I wrote in Nitrogen control, and air in the soil. Root hairs are short-lived and have a high oxygen demand, so they need fresh air. I don't want you to misunderstand, but it's not that it's okay to make the soil layer soft and fluffy as humans feel. When it is pulverized finely by rotary plowing, it seems to be soft, but after rain, it becomes hard and easy to compact. The important thing is to increase the layer of air called the air phase ratio in the soil.
In general soil, it seems to increase due to the development of humus due to the input of so-called organic matter. If you read a soil science book, it says that the vapor phase ratio is largely determined by the physical properties of the soil (the ratio of clay and sand, which are called base materials). It is necessary to think about soil preparation according to management because the preferred environment differs depending on the planting item. This is the purpose of doing so-called soil preparation. However, no matter how high the gas phase ratio is, nothing will happen if a large amount of nitrogen remains in the initial stage.
<4) Increase the temperature difference>
As I wrote in the first half, A large difference is very advantageous for making delicious food. The reason why a large temperature difference is advantageous is that the amount of respiration at night decreases. This is because the cooler the nights are, the less sugar is consumed during the day because the amount of respiration is reduced.
In the case of tunnels and greenhouses where the temperature can be controlled artificially, rather than warming it up, managing it with a feeling of lowering the night temperature will make a big difference. The difference in the products produced by this difference in temperature control is very large. After all, since it is a daily occurrence, even a slight difference in temperature during the growing period appears as a considerable difference. However, this does not mean that the daytime temperature should be raised. If the growth temperature is exceeded, the amount of sugar produced by photosynthesis will be exceeded and respiration will become intense, which will have the opposite effect. It's all about the right temperature range for growth.
I hope the above is of some help.
