First, prevent leggy
When the peanuts are full, the vegetative growth gradually decreases, nutrients transfer to the pods, and dry matter accumulates rapidly. However, due to various reasons such as temperature, rain, light and excessive application of nitrogen fertilizer, the peanuts are stalks and leaves, they are prematurely closed, and the field is closed. They consume large amounts of nutrients, inhibit the accumulation of dry matter in fruits and affect the yield. Therefore, for peanuts with an imperishable trend, measures must be taken to suppress vegetative growth and promote reproductive growth, which will have a significant effect on improving peanut production.
Second, prevent premature aging
For the field of premature aging caused by lack of fertilizer, 0.3%-0.4% potassium dihydrogen phosphate plus 1% urea solution 50 kg should be sprayed on every mu root from the fruiting stage to the full fruiting period. The best spraying time is 4 o'clock on sunny days. Afterwards, spray once every 10 days, usually 2-3 times.
Third, prevent water accumulation
In the later stages of peanut growth, there must be no accumulation of water in the peanut field. In case of rain or continuous rain, it is necessary to drain water in time to prevent accumulation of water, so that the humidity in the field is too large, the stems and leaves are long, the soil is poorly ventilated, and the roots and pods are affected, and it is easy to cause a lot of rotten fruit or germination and reduce the yield and quality. To grow peanuts in plots with high groundwater levels, high-riding cultivation or digging drainage ditch must be implemented to reduce the water level.
Fourth, prevent pests and diseases
The most important disease in the later period of peanut is leaf spot disease. In prevention and control, it should be sprayed 1-2 times 1:1 300 times Bordeaux mixture for prevention before onset. In the early stage of disease, 50% carbendazim WP 800 times solution can be used for prevention and treatment. The main pests in the later stages of peanuts are ground pests, which are mainly maggots, and should be controlled in time. Late locust occurrence, when the pest rate reached more than 5%, can be used 10% imidacloprid WP spray control.
