What measures should be taken to achieve high yield of summer peanuts?
Summer peanut mostly refers to wheat stubble peanut, its growth period is 30-40 days shorter than that of spring peanut, and each growth period is shortened accordingly. The rapid growth in the early and middle stage and the low temperature in the later stage are disadvantageous to the development of pods. Therefore, the following measures should be taken. (1) early-maturing and high-yielding varieties were selected. (2) early broadcast in the rush time. Fight for the day in spring and time in summer.

What is the principle of fertilizing peanuts?
The main results are as follows: (1) Farm manure is the main and chemical fertilizer is the auxiliary. In China, peanuts are mostly planted in hilly areas, with thin soil layer and low fertility. Farm manure is mainly organic fertilizer, which is rich in nutrients, which can improve soil, fertilize and fertilize the soil for a long time. Chemical fertilizer is a quick-acting fertilizer, although it also contains the nutrients needed by peanuts, but with.

What are the requirements of soil conditions for high yield of peanut
(1) the whole soil layer is deep. The whole soil layer of high-yield fields should be more than 50 centimeters. 99% of peanut roots are distributed within 50 cm, and the main roots are more than 1 meter deep. Therefore, the depth of soil is very important for the growth and development of peanut roots. (2) the tillage layer is active. Thickness in the range of 30 cm is Xuan live fertile tillage layer, also.

Mung bean summer direct seeding technology
When mung bean seedlings reach 2 leaves and 1 heart, pimple seedlings should be removed. When 4 leaves are fixed, the plant spacing is 13 to 16 cm, the row spacing is about 40 cm, leaving 1 to 15000 seedlings per mu, and those who sow late can stay at most 20, 000 plants. Mung bean from emergence to flowering and sealing line, to adhere to diligent ploughing and weeding, generally not less than 4 times, mid-ploughing depth from shallow.

Apply sufficient base fertilizer to mung bean
Although mung bean rhizobium has the ability of nitrogen fixation, the application of farm fertilizer and phosphorus and potassium fertilizer can obviously increase the yield. Before sowing, 2500 kg of farm manure, 20 kg of phosphate fertilizer and 1 kg of biological potash fertilizer were applied as base fertilizer per mu. If the field that is too late to apply base fertilizer, in the early stage of growth, that is, branching, the first flowering stage, the application of three-yuan compound fertilizer 7.5 thousand per mu.

Mung bean seedling management seed germination should not be too long
In case the seedlings are weak. Excessive humidity is one of the important causes of stunting disease, so the appropriate humidity should be controlled at seedling stage. Irrigation before sowing should be appropriate, too large, high humidity, and lower soil temperature; too small, the seedling stage to increase the number of watering, not only labor-consuming, but also increase humidity. In the early stage of seedling emergence, fine soil can be sprinkled on the bed.
