Ways of out-of-season vegetable cultivation

Out-of-season vegetable cultivation refers to a middle school planting technology that produces ahead of time or postpones production. It is a very popular cultivation technique in the market at present, and it can ensure that most vegetable varieties can be supplied and listed all the year round. However, due to out-of-season planting, will destroy the nutrients of vegetables, so there are still some people can not accept. So what are the ways of out-of-season vegetable cultivation? Let's take a look at it next.

1. Early maturing cultivation

Precocious cultivation generally refers to a way of planting when the planting time has not yet been reached and does not meet the planting conditions. It is mainly the use of protective equipment, heat preservation, or cold protection, planting in advance to promote the growth and development of vegetable plants, so that it can be harvested and put on the market as soon as possible. Vegetables listed in this way are generally called early-maturing varieties.

2. Delayed cultivation

The way of delayed cultivation mainly refers to the vegetables that can be harvested in winter by sowing in summer, but can be delayed by planting with protective equipment in autumn. It can prolong the growth cycle of vegetables, which can prolong the supply period of such vegetables.

3. Cultivation in hot summer

Summer weather is generally relatively hot, and the rainfall is also relatively large, that is, people often say that the high-temperature and rainy climate. Many vegetables can not be grown in summer, but now we can use the way of building shade to cool down and prevent rain, to achieve the purpose of regulating the external environment, while the out-of-season planting of progressive vegetables.

4. Overwintering cultivation

Overwintering cultivation and summer cultivation are actually a kind of cultivation method produced by using the opposite principle. Generally, shelter and plastic sheds are used to achieve a heat preservation effect, so that some vegetables that are not cold-resistant originally can be planted in winter, and these vegetables can survive the winter safely under protective equipment, and can be put on the market in advance in the spring. Such as spinach, leek, coriander and so on can be grown.

5. Facilitative cultivation

Promoting cultivation is actually a very similar planting method to overwintering cultivation. It is in cold weather, the use of greenhouse planting, as well as other heating equipment to raise the temperature in the greenhouse, promote the rapid growth of vegetables, so as to achieve the purpose of listing. This out-of-season cultivation method causes more serious damage to the nutrients of vegetables than overwintering cultivation.

6. Softening cultivation

The way of softening cultivation may not be understood by many people, because it is not particularly common in our lives. It is mainly the use of softening chamber or other softening methods to promote some specific vegetables to form soft and yellowing organs in a specific environment. In this way, many vegetables can be put on the market all the year round, such as onions, ginger, garlic and so on.

These are the six cultivation methods of out-of-season vegetables, of which early-maturing cultivation and delayed cultivation are the most commonly used in the market. Out-of-season cultivation of vegetables, although you can eat vegetables you want in every season, but a lot of nutrients are destroyed, not very healthy vegetables. But it is also necessary for it to appear.
