Mid-late management of coated summer peanut

First, drought prevention and flood control promote growth of peanuts in the middle and late needs sufficient water, but fear of drought, in the dry weather should be watered in the morning or evening. Peanuts on dry slopes should always be exposed to water and sun; in the rainy days, open irrigation and drainage ditch, ring-shaped ditch, etc., and quickly drain the water in the field to prevent the roots and the lodgings of peanuts from falling.

Second, timely supplementation of fermented pods late seed or poor growth should be promptly supplemented with nitrogen, potassium fertilizer, increased application of potassium, calcium fertilizer, acre with urea and potassium chloride each 4 to 5 kg or compound fertilizer 8 to 10 kg. Cover the soil after applying the hole at the side of the plant. The three types of seedlings with poor growth should increase the topdressing of the roots one or two times.

Third, disease prevention and control of pests The main pests and diseases that endanger peanuts in this period are leaf spot, rust, cockroaches, cotton bollworm, etc. If not timely control, it is easy to cause leaf loss and green leaf area reduction.

1. Prevent disease. Prevention and treatment of leaf spot and rust, according to the condition after the onset of carbendazim, methyl thiophanate, mancozeb, chlorothalonil and other agents, foliar spray 2 to 4 times for prevention and treatment, two sprays The interval is 10 to 15 days.

2. Treatment of insects. If the plots that have not been planted with "812" during the sowing of peanuts are found to be damaged during the growth period, they can be filled with methyl isophosphorus or phoxim solution during the pod-forming period. High temperature and humidity in summer is conducive to the occurrence of cotton bollworm. It can be sprayed with new pesticides such as Baode, insecticide, and Qiansheng in time after the prevention and control indicators. It was found that the aphids can be sprayed with 700 times of malathion solution 1 or 2 times; the Spodoptera litura can be sprayed with 700 to 800 times of trichlorfon. At the same time, the voles were killed with the sodium salt of the enemy rats.

Fourth, spraying foliar fertilizer In order to prevent the peanut pod expansion period to extend the leaf function period and increase the pod fullness, the foliar fertilizer such as too fat and chlorophyll can be sprayed every 7-10 days in the late stage of pod formation.

5. Spraying the growth regulator at the appropriate time in the early stage of the pod to prevent the plant from growing long, maintaining a high and stable effective leaf area, increasing the photosynthetic rate, and increasing the rate of vegetative photosynthetic product transfer to the pod. The growth regulators such as schizozotocin, peanut treasure and Zhuangshen are controlled.

Sixth, do a good job in other related links 1 soil, the first time shallow soil, the second flower re-cultivation; 2 flowering pods each spray a high-yield, each (10 ml) plus water 60 kg evenly sprayed on the leaves and The stem can also be combined with the insecticide to add the liquid; 3 timely harvest to ensure the quality.
