Peanut planting technology: how to manage peanut mid-growth?

How to manage peanuts in the middle stage of growth? Please guide the management of peanut in the middle growth period with reference to the following methods: first, skillfully chasing flower and fruit fertilizer in the middle growth stage, peanut vegetative growth and reproductive growth reach the peak at the same time from the initial peak stage, not only the stems and leaves grow faster, but also a large number of plants blossom and needle, a large number of fruit needles enter the soil to develop into pods, and the demand for nutrients increases. Therefore, for the fields without topdressing at the seedling stage, it is necessary to topdressing 7.5kg / mu of urea, 25kg / mu of calcium superphosphate and 10kg of potassium sulfate at the early flowering stage, and to apply 20kg / mu gypsum powder at the full flowering stage to promote pod development and improve the satiety rate. In addition, if the heart leaves of the plant are yellow, white and green, 0.3%-0.5% ferrous sulfate solution should be sprayed. Second, cultivating the soil to welcome the fruit needle can thicken the soil layer, make the fruit needle enter the soil early and bear fruit early. Soil cultivation should be carried out before the field has just closed ridges, a small number of fruit needles have been buried, and a large number of fruit needles have been buried. The method of soil cultivation is to tie a grass ring on the hoe hook and pull the soil on both sides of the base of the peanut, but do not bury the base of the stem. Soil cultivation is generally carried out in two stages, and the second time is carried out about 10 days after the first soil cultivation. Third, watering and drainage flowering needle stage and podding stage are the critical period of water demand of peanut, which is very sensitive to water, so we should pay attention to water management. The suitable soil water content at the flowering stage and podding stage is 60%-70% of the maximum field capacity, and should be watered in time in case of drought. Watering method should choose sprinkler irrigation or small water fast furrow irrigation, do not flood irrigation. Timely drainage after precipitation, so as not to cause a large number of rotten fruit, reduce yield and quality. Fourth, controlling the tree to maintain stable growth in the middle growth stage, peanuts are very easy to lodge after overgrowth, resulting in a serious reduction in yield. Therefore, the middle and high yield peanut fields should be sprayed with 50 grams of 15% paclobutrazol wettable powder and 50 kg of water at the end of flowering stage and when the main stem is more than 40 cm high, so as to control the up and down and prevent plant lodging. Control of diseases and insect pests the main diseases and insect pests in the middle stage of peanut are leaf spot, grub and cotton bollworm. At the initial stage of the onset of leaf spot, 40% carbendazim glue suspension 1000 times or 50% topiramine wettable powder 1500-2000 times solution can be sprayed, once every 7-10 days, 2 times 3 times, 50 kg per mu. For the control of grubs, the poisonous soil should be made by mixing 3% isofenphos granule 2.5 kg / mu or 50% phoxim 0.25 kg plus fine soil 30 kg / mu into poisonous soil, spread along the ridge near the plant, and cultivate the soil after sowing. The cotton bollworm can be sprayed with 1500 times solution to control cotton bollworm. Click to get more peanut planting techniques click to get more food crop planting techniques
