Clean up gully in time and rule out water in the field. Due to the recent rainwater, the gully in the peanut field was destroyed, which is not conducive to the discharge of water in the field, resulting in anoxic soil and affecting the absorption of nutrient and root respiration. Therefore, the gully should be cleared up in time to eliminate water in the field, create a suitable soil environment, and promote the growth of peanuts.
After cultivating and weeding, the soil is easy to be compacted after the peanut field has been submerged and the soil is easy to compact. The cultivator can remove the excess water, increase the permeability of the soil, and help the root system recover. Due to long-term exposure to rain, peanut fields are prone to weeds and weeding should be done in combination with cultivators. For ridged peanut farms, cultivating is not easy, but field weeds should be removed manually.
Timely fertilization to prevent premature aging due to rain erosion, a large number of base fertilizer loss, easily lead to defermentation of peanut field. Peanut mulch can be used to drill the top dressing, open ground peanuts combined with cultivator topdressing, usually topdressing urea 5 ~ 10 kg per mu, conditions, can increase the amount of calcium fertilizer, promote pod expansion. In the late growth stage of peanuts, spray 50-kilograms of a mixture of potassium dihydrogen phosphate and 1% urea in an amount of 0.3% to 0.5% per acre, spray once every 7 to 10 days, and spray for 2 to 3 times, which can effectively prevent Premature decline in peanuts, increase production.
In a timely manner, chemical regulation is applied to the peanut field where there is an impervious trend after flooding and the group is prematurely ridged. In the late flowering stage or when the plant height is 35 to 40 cm, a paclobutrazol solution with a concentration of 15010-6 or 5010-6 per acre is sprayed. The 50 kg of Uniconazole solution up to 7010-6 can effectively control the vegetative growth of peanuts, promote reproductive growth, prevent fields from being covered, and increase yield.
Peanut Strengthens Management and Increases Production
Yan Xiuwang, deputy researcher of the Provincial Institute of Agricultural Economics of the Provincial Academy of Agricultural Sciences, said that there has been more rains recently and management of peanut fields should focus on the following aspects:
