There is a significant increase in the yield of planting peanut with three control measures.

1. Anti-apprenticeship. For peanut fields with high soil fertilizer, good fertilizer and water conditions and exuberant plant growth, spraying hormone, that is, plant growth regulator, can inhibit vegetative growth and promote reproductive growth. Coordinate the relationship between vegetative growth and reproductive growth. There are three kinds of plant growth regulators suitable for spraying on peanuts, such as Bijiu, dwarf and paclobutrazol. The dosage per mu is: 50 kg for every 50 g, 50 kg for 100 g, and 35 kg for 15% paclobutrazol wettable powder. The spraying time is usually in the early stage of podding.

2. Prevent premature senility. Maintaining the green leaf area and the physiological function of leaves in full fruit stage is an important key to increase fruit number and yield. In production, the prominent problem is that after entering the full fruit stage, the leaf area and photosynthetic productivity drop sharply at the same time, the dry matter accumulation decreases to a very low level, and the phenomenon of premature senescence occurs. Production is generally reduced by 20-30%. To prevent premature senescence, foliar fertilizer is generally sprayed from the podding period to the early satiety stage. 75-100 kg per mu of liquid fertilizer (containing 0.2% potassium dihydrogen phosphate, 2% calcium superphosphate, and 1% MUR 2% urea for the plots with weak plant growth and yellow leaves), sprayed once every 7-10 days, usually sprayed twice, after 4: 00 p.m. At the same time, attention should be paid to timely irrigation under drought conditions, which can promote the prevention of premature senility.

3. Prevent diseases and insect pests. The main disease of peanut is leaf spot. Leaf spot is a fungal disease, which can be promoted by high temperature, humidity or continuous overcast and rain. its symptom is brown or black spots on the leaves, and in severe cases, it also infects petioles and stem branches. Generally speaking, the output will be reduced by about 25% in the middle and later stages. In the prevention and control in line with the principle of prevention is more important than treatment, early treatment of small, once it occurs as soon as possible. Control methods, in addition to strengthening field management, promoting the growth of peanuts and enhancing the ability of disease resistance, pesticides can also be selected for control. The main pests of peanuts are aphids and grubs. Aphids occur in the whole growth period, which not only affects the normal growth of peanuts, but also infects peanut virus disease and reduces production. Spray methamidophos 1000 times of methamidophos in 1000 times of dimethoate emulsion. The control methods of grubs: in late June and early July, the adults were sprayed with isocarbophos 800-1000 times. When grubs occur seriously, the roots can be irrigated with 500-700 times of phoxim, and the effect of irrigation before rain is better.
