Peanut, strengthen management and increase production

Yan Xiuwang, an associate researcher at the Institute of Economic Crops of Henan Academy of Agricultural Sciences, said that there have been more rains recently, and the management of peanut fields should focus on the following aspects:

Timely cleaning of gullies and eliminating water in the field Due to the recent rains, peanut gullies have been damaged, which is not conducive to the discharge of water in the field, resulting in soil oxygen deficiency, affecting the roots of peanuts and the absorption of nutrients. Therefore, the ravine should be cleaned up in time to eliminate the accumulation of water in the field, create a suitable soil environment, and promote the growth of peanuts.

After cultivating and weeding, the soil is easily squashed and the soil is easily sown in time. It can disperse excess water, enhance soil permeability and help the roots to recover. Due to the long-term effects of rain and rain on peanut fields, weeds should be combined with cultivating for weeding. For peanut fields that have been closed, it is not easy to carry out cultivating, but the field weeds should be removed manually.

Timely fertilization, to prevent premature aging due to rain erosion, a large loss of base fertilizer, easy to cause peanut field de-fertilization. The mulch peanuts can be top-dressed by means of perforation. The open-ground peanuts are combined with cultivating for topdressing. Generally, 5 to 10 kg of urea is applied per acre. If conditions permit, a certain amount of calcium fertilizer can be added to promote the expansion of the pods. In the late growth stage of peanuts, spray 50% of a mixture of 0.3% to 0.5% potassium dihydrogen phosphate and 1% urea per acre of leaf surface, and spray 2 to 3 times every 7 to 10 days to prevent peanuts. Premature aging, increase production.

Timely chemical regulation of peanut fields with long-term tendency after flooding and premature closure of the ridges. When the flowering stage is late or when the height of the plants is 35-40 cm, the paclobutrazol solution with a concentration of 150×10-6 is sprayed per mu or 50. ×10-6 to 70×10-6 of the uniconazole solution 50 kg can effectively control the vegetative growth of peanuts, promote reproductive growth, prevent field depression and increase yield.
