When will mung bean seeds be sown? How to apply fertilizer? What are the planting techniques?

We know that the heat-clearing function of mung bean lies in the skin and detoxification in meat. Mung bean soup is a regular summer refreshing drink for families, which is suitable for all ages. So let's see when the mung bean seeds will be sown here. How to apply fertilizer? What are the planting techniques?

When will mung bean seeds be sown?

The best time for spring sowing of mung bean is from May 10 to 25, and the best time for summer sowing is from June 10 to 20, which should not be later than the end of June. In Jinzhong area, the varieties with short growth period should be selected as far as possible and sown before July 10. Mung bean is a temperature-loving crop. If sowing in spring is too early, the individual development is poor, the growth period is prolonged and the yield is reduced. It is better to sow mung beans early in summer, the seedlings grow healthily, and the flowering and podding stage is in the stage of high temperature and rain, which is beneficial to the formation of flowers and pods, many pods, many seeds, grain weight and high yield. In addition, the early sowing mung bean seedling stage is before the arrival of the rainy season, which is conducive to field management, time seedling, mid-ploughing and weeding, so as to achieve full seedling, strong seedling, no grass famine, no consolidation, no diseases and insect pests. Sowing too late will lead to malnutrition in the early stage, miss the high temperature period, fail to form a large number of flowers and pods in the later growth stage, reduce grain weight, and are vulnerable to the effects of rain, waterlogging and low temperature, resulting in reduced yield.

Second, how to fertilize mung beans?

1. The best basic fertilizer is human feces and urine, plant ash, Kang soil and pig, chicken and sheep manure, which is 1000-3000 kg per mu.

two。 Topdressing should be timely and appropriate, suitable for trenching between rows at seedling stage and flowering stage, applying urea or compound fertilizer 5-10 kg or 8-15 kg per mu respectively. 1.0% urea and 0.5% potassium dihydrogen phosphate can be sprayed during the whole period from branch to harvest, usually once every 10-15 days.

Third, what are the mung bean planting techniques?

The sowing methods of mung bean are strip sowing, hole sowing and sowing, and most of them are strip sowing. The sowing rate should be determined according to the characteristics of varieties, climatic conditions and soil fertility. Generally, the amount of seed should be guaranteed to be more than 2 times the number of seedlings left. If the sowing rate is too large, the seedlings are crowded, and it is easy to form weak seedlings; if the sowing rate is too small, it will cause lack of seedlings and broken ridges. Such as good soil quality, sufficient soil moisture, few insects, good soil preparation quality, planting small grain varieties, sowing quantity should be less; on the contrary, sowing quantity can be increased appropriately. In view of the fact that the ability of mung bean cotyledon arch soil is weak and the plant has the population growth habit of "thick, non-resistant and sparse", it is necessary to increase the sowing rate in heavy soil. Generally, strip sowing is 1.5-2 kg per mu and sowing is 4 kg. The seed amount of intercropping and interplanting depends on the planting situation. Sowing depth has a great influence on seedling emergence rate, which depends on soil condition, moisture, seed size and sowing date. In clay and wet soil, the sowing depth should be shallow, 3-4 cm is appropriate; the soil is loose and soil moisture is poor, and the sowing depth is 4-5 cm. From June to July, there are more Rain Water, and the temperature is high, so it should be shallower; in spring, the soil moisture evaporates quickly, and the temperature is lower, but it can be a little deeper.
