High-quality and high-yield fertilizing method for continuous cropping peanut planting

Abstract

The invention discloses a high-quality and high-yield fertilizing method for continuous cropping peanut planting. The method comprises following steps: (1), by combination with land preparation and bottom application before sowing of peanuts, 60-100 kg of high-concentration balance type humic acid complexed organic and inorganic compound fertilizer is applied per mu, and 40-80 kg of amino acid high-calcium organic fertilizer is applied per mu; (2), foliage spray of fulvic acid microelement liquid fertilizer is performed one or two times at the seedling stage of the peanuts, foliage spray of the fulvic acid microelement liquid fertilizer is performed two or three times at the initial flowering stage and full-bloom stage, the interval of every two times of spray is 5-7 days, and spraying isperformed uniformly each time. By means of bottom application fertilizer, continuous cropping obstacle of the peanuts can be controlled better, the characteristics of the humic acid fertilizer can bebetter exerted, and ecological functions of soil are optimized and improved; by means of cooperative application of the bottom application fertilizer and foliar fertilizer, the per mu yield reaches 650-900 kg, furthermore, top dressing times are reduced, top dressing is even not needed, cost saving and synergism effects are realized, and the environmental threat caused by unreasonable applicationof chemical fertilizer is reduced.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a high-quality and high-yield fertilization method for repeated cropping of peanuts. Background technique [0002] Peanut is a crop that grows above the ground and bears fruit underground. Before the 1990s, due to the low level of investment and the lack of fertilizers, the yield of peanuts per mu was only 300-400 jin. Since the 1990s until today, most of the peanut yields per mu have been hovering at 500-800 jin, which is at a low yield level. There are three fundamental reasons why peanuts are high-yield crops but the actual yield is at a low level: one is that the yield per mu of peanuts has been at a low level of several hundred catties for decades, and it has been mistaken for low-yield crops, and the fertilizer input is at a low level; Peanuts should avoid repeated cropping, which will inevitably lead to low yield, poor quality, and serious diseases.

There are three fundamental reasons why peanut is a high-yielding crop but the actual yield is at a low level: one is that the yield per mu of peanut has been at a low level of several hundred catties for decades, and it has been mistakenly treated as a low-yielding crop, and the fertilizer input is at a low level; Peanuts should avoid repeated cropping, which will inevitably lead to low yield, poor quality, and serious diseases. The problem of repeated cropping is also called the problem of repeated cropping. After research, the root cause of repeated cropping obstacles is the accumulation of bacteria, autotoxicity, and nutritional imbalance. , and the main peanut production areas are almost all planted with heavy cropping, and there is no effective prevention and control of heavy cropping obstacles; third, the application of phosphorus fertilizers is unscientific, and only inorganic fertilizers are applied, the soil lacks organic matter, and the advantages of nitrogen fixation of peanut root nodules have not been fully utilized. And late, do not apply calcium fertilizer, etc., did not satisfy the habit of peanuts who like phosphorus and calcium
