The spring season coincides with the sowing of warm-temperate vegetables such as melon and beans, and at the same time the winter cropping fields must be released to plant early Rice crops. Due to the season of crop replacement, the area of ​​vegetable fields listed for vegetable supply will be reduced, and the amount of vegetable marketed should be reduced. Some, if March and April hit a sustained low temperature and rainy or rainy weather, vegetable sales will be further reduced. Spring vegetables (3,4 months) listed vegetable varieties are mainly winter vegetables planted leafy vegetables, these vegetables have strong cold resistance, require short days before it will not be too early to bolting. However, there are frequent low temperature and rainy weather in Guangdong and Guangzhou in February and March of each year, causing chilling and wet damage to vegetable crops. Cold injury, on the one hand, makes hi, melon, beans, and other vegetables that are hi, warm and can not normally grow seedlings, or even appear rotten seedlings and rotten seedlings, thus delaying the period of listing and supply; on the other hand, low temperatures will promote the early adoption of weak winter leafy vegetables. In the vernalization stage, it enters the lighting stage. After entering Guangdong and Guangzhou in March, due to the extension of sunshine (the number of hours), the temperature has risen, which has also prompted the winter weak leafy vegetables to pass through the lighting stage and lead to early bolting and flowering, thus ending the period of listing and early delivery. As a result, production and varieties have declined, and the volume of listing has decreased. In the spring, when there is rain and sunshine, the damage to the roots of the vegetable crops caused by dampness leads to decline; the soil also produces poisonous substances that damage the vegetable crops and induce pests and diseases. Due to the foregoing series of reasons, after a large number of leafy vegetables were harvested in February and March, the spring sowing and warm melon and beans were still not on the market in time, and the storage season in March and April did not occur due to the lack of green and yellow. With the circulation of the market and the reform of the vegetable system, the lack of food in the off-season in the spring has been greatly reduced. However, in the case of continuous low temperature and rainy weather, there will still be high prices for food. Measures to solve the problem of spring vegetables are: 1, choose a strong winter varieties, late bolting of vegetable varieties, highlighting late broccoli, late kale, late spinach, etc., to delay the harvest time of winter vegetables. 2, arrange more varieties with strong cold resistance, such as March cabbage heart, Chinese cabbage, red slow cabbage, kale head, etc. These varieties can be delayed until March and April listing. 3, the development of protected land production, increase the temperature of the vegetable field, soil temperature, in order to advance the spring market. 4, after the late rice harvest last year, the appropriate expansion of the species can be extended to March and April listing of winter vegetables. 5. To use the climate resources in the early spring and early spring in southwestern Guangdong and Hainan Island to establish a cross-regional production base for spring vegetables.
Selenium-enriched rice grows selenium-rich rice by selenium supplementation when rice is grown. It is a functional agricultural product and is a food rich in selenium with high nutritional value.
