First, timely release of seedlings, replanting, and clearing branches. When the seedlings are green, the soil (heap) above the seeding line is removed to the furrow to expose the cotyledonary nodes. Where the peanut seedlings can not be automatically ruptured, it is necessary to artificially rupture the membrane to release the seedlings. After the seedlings, it is necessary to check the seedlings in time, and continuously vaccinate more than 2 piers. Beginning with the sapling stage (the main stem has 4 compound leaves), it is necessary to check and extract the lateral branches buried under the membrane in time to make it grow vigorously. It takes 2 to 3 times before the flowering .
Second, timely irrigation and drainage, drought prevention, flood control. The spring and summer peanuts sowed in the foot can not be watered in the seedling stage. Suitable drought is beneficial to the development of the root system and improve the drought resistance and tolerance of the plants. There is a drought in the seedling stage of wheat, and it is necessary to water and protect the seedlings in time. The mid-fertility period (flowering period and pod-forming period) is the most sensitive period for peanuts to respond to water, and it is also the period of most water demand in a lifetime. When the leaves of plants are wilting around noon, they should be watered in time. In the late growth stage (full fruiting period), it is necessary to timely watering and moistening the small water to prevent premature senescence and aflatoxin contamination of the pod. In addition, the peanut field should have three smooth communication and no water damage.
Third, timely cultivating, topdressing, and killing grass. The wheat peanuts are ploughed and weeded in time after the wheat harvest. The plot that needs topdressing is ditched and topdressed on the side of the peanut plant, and then the soil is watered, suitable for cultivating. When the peanuts in the field are close to the ridge, the soil is cut through the two rows of peanuts, and the soil is cultivated to make the ditch clear, the soil ridge, the ridge waist fat, and the ridge top concave, so that more fruit needles are sturdy.
Fourth, timely prevention and treatment of pests. When the leaf rate of peanut disease reaches 10% , spray the leaves with 60% Baitai wettable powder 1500 times solution, 70% methyl thiophanate WP 500 times solution, 43% tebuconazole 1500 times solution and other fungicides. Face, even spray 2 to 3 times, interval 10 to 15 days, prevention and control of leaf spot, net spot disease. Root knot nematode disease can be rooted with 1.8 % avermectin EC 1000 times solution. Foliar application of 1.8% avermectin EC 2000 ~ 3000 times solution, or 40% phoxim EC 1000 ~ 1500 times solution, control of cotton bollworm, Spodoptera litura and other pests.
Fifth, the early control of the anti-professor. When the height of the main stem of the peanut reaches 30 ~ 35cm (general field) or 35 ~ 40cm (high yield field), use 5% uniconazole 40 ~ 50g wettable powder per acre (active ingredient 2 ~ 2.5g ), add water 35 ~ 40kg foliar spraying, if the main stem height of more than 45cm can be sprayed once again, seed rate and full fruit set.
Sixth, root dressing to prevent premature aging. After entering the full fruit period, prevent premature aging. Foliar Nutrition of KH2PO4 per acre 120 ~ 150g + urea 350 ~ 400g + 75% chlorothalonil WP 70 ~ 80g fungicides such as a mixture of 35 ~ 40kg, and even spray 2, spaced 10 to 15 days, Extend the functional period of the parietal leaf.
