Fruits and vegetables are shipped from Hainan in winter in most parts of northern China, and the favorable conditions for producing anti-season vegetables in Hainan Island are analyzed.

Hainan is rich in light and heat resources, which is suitable for planting out-of-season vegetables and fruits in winter.

Vegetables and fruits planted out of season are not fully planted in greenhouse environment. In off-season planting, it can be mainly divided into two categories:

1. Use the three-dimensional climate resources and environment in mountainous areas to plant vegetables and fruits in summer and autumn.

2. Take advantage of the warm microclimate in winter and spring to plant anti-season vegetables and fruits in winter.

Hainan belongs to this second category.

Specific methods of anti-season planting:

1, out-of-season planting in high mountains

2. Off-season planting of thermal insulation facilities

3. The sunshade net is planted out of season.

Advantages and disadvantages of out-of-season vegetables;

From the planting point of view, out-of-season fruit itself should be harmless. They generally grow in greenhouses and do not need to use hormones. However, some unscrupulous fruit farmers often overuse hormones such as plant growth regulators in order to increase their yield. These hormones can promote fruit development, growth and early maturity, and increase yield by about 20%.

Although the "hurried" out-of-season fruit is pleasant in color and the pulp inside is not mature, it looks delicious, but in fact, not only can you not eat the sweet taste in your mouth, but the nutrients in the fruit are also shrinking!

Although people always associate pesticides with chemical pollution and worry that it will cause food safety problems, the purpose of pesticides is clear, and its original intention is to benefit mankind.
