First, the prevention of premature failure peanuts from the stage of pod till the full fruit period is the time when more water and fertilizer is needed. If the supply of water and fertilizers is insufficient, plant growth will be poor, the growth potential will be poor, the leaves will be yellow, and premature aging will occur, resulting in the reduction of green leaf area of ​​peanuts and the decline of photosynthetic capacity. Manufactured nutrients are less, dry matter accumulation is reduced, and the speed of transportation to pods slows, affecting production. Due to lack of fertilizer due to premature aging, the field should be sprayed with 0.3%-0.4% potassium dihydrogen phosphate plus 1% urea solution for 50 kg per 667 m2 of root during the fruiting period from fruiting to full fruiting. The best spraying time is on sunny afternoons. After 4:00, spray once every 10 days, usually spray 2-3 times, can effectively add nutrients to prevent premature aging. Second, anti-adult peanut full fruit period, vegetative growth gradually decreased, a large number of nutrients transferred to the pods, rapid accumulation of dry matter. However, due to various factors, such as temperature, rain, light, and excessive nitrogen fertilizer application, peanuts stems and leaves are long, prematurely sealed, and the fields are closed. They consume large amounts of nutrients, inhibit fruit dry matter accumulation, and affect 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. Third, the prevention of stagnant peanuts has "magpie heavens, not greedy to the ground" and "dry ground no needle, wet not drum grain" characteristics. Especially in the later stages of peanut growth, the peanut field must not have accumulated water. 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. 4. The main disease in the late stage of disease prevention and control peanuts is leaf spot disease. The chlorophyll of the damaged leaves is destroyed and the light and the effect are reduced, resulting in early defoliation, affecting dry matter accumulation and fruit ripening, generally reducing production by 15% to 20%, and severely reducing the yield by 40. %the above. In prevention and control, 1:1:300 times Bordeaux mixture should be sprayed for prevention 1-2 times 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. 5. In the middle and late stages of the growth of weed-prevented peanuts, due to the high temperature and rainfall, it is easy to breed weeds. According to the survey, many farmers have mistakenly thought that the weeds in the later period have little effect on the growth of peanuts and allow them to grow. In fact, weeds, especially humulus, seriously affect their ventilation and light transmission, and absorb large amounts of water and nutrients, affecting the fullness of peanuts and fruits. 6. Timely harvest When the top of the peanuts, the leaves of the fruiting branches turn yellow, most of the middle leaves have fallen off, and the reticulation of the fruit shells is clear. After peeling the pods, the sponge layer in the fruit shell has a black luster. The grain is full, the seed coat is ruddy, and the whole fruit rate reaches At 85%, peanuts have matured and must be harvested in time. Early and late harvests will reduce quality and yield.
