Fresh soy and corn sowing at different stages can stagger the harvest period of both, extend the supply period, and obtain higher economic benefits. There are three principles for good sowing in stages: A look at the facilities of growers. In general, the earlier the cultivation in early spring, the higher the income. However, the sowing time for promoting early cultivation depends on the conditions of the insulation facilities. From mid-February to early March, small arch sheds can be used for cultivation. In the middle of March to the end of March, mulching can be used for mulching, and after the beginning of April, it can be cultivated in an open field. Of course, there are differences in the sowing period in different regions, and southern Zhejiang can be sown about 7-10 days earlier than in northern Zhejiang. Second, look at the local climatic conditions. Generally spring soybean and spring corn can only be sown when the soil temperature is stable above 10°C, and insulation measures should be taken when sowing early. Summer soybean and summer corn should pay attention to avoid high-temperature and dry weather during flowering, otherwise it is easy to cause falling soybeans and corn empty stalks. In late autumn, the cultivation should be delayed and the sowing period should be moderate. In the absence of late insulation measures, the sowing is too late to be affected by the low temperature in autumn, and the grouting is difficult and difficult to harvest. Third, we must do a good job with varieties and mix. According to different planting methods and planting season, different varieties can be used to achieve high yield and high efficiency. Spring soybeans, summer soybeans, and autumn soybeans all have their own requirements for the length of sunshine. Therefore, all types of soybeans should not be mixed, especially autumn soybeans. Soybean sowing in spring should also use different varieties according to different cultivation measures. For the use of greenhouses, small sheds, etc. to promote early-growth cultivation, the varieties with a growth period of no more than 75 days and good cold resistance, such as "Tengdou 9701", should be selected so as to maximize the advantages of facilitating cultivation; the intercropping also Early maturing cultivars should be selected, and the growth period should not exceed 80 days in order to shorten the symbiotic period of the crops and reduce the adverse effects of different crops. In the case of mulching and conventional cultivation, comprehensive determination of fertility can be made based on the situation of estuary and harvest time. Period, but it should not exceed 95 days. Of course, the effect of staggering the harvest period can also be achieved by sowing seeds of different ripening dates in the same period. Corn is not sensitive to the length of sunshine. Therefore, the same variety can be planted in spring, summer and autumn. The varieties are mainly selected according to different cultivation conditions and consumption habits.
