A layered fertilization method for peanuts in loose bales

Abstract

The invention discloses a dispersed buried row-applying layered fertilization method for peanuts. The method comprises the following steps: 1 / 2 of a fertilizer is evenly applied to a fruiting layer, on a ridge, of 0-10 cm in thickness, by using a peanut sowing machine and in a buried manner; the remaining 1 / 2 of fertilizer is evenly divided into 3 parts for respectively applied to the center of the ridge and the soil layer, below two sowing rows, 10-15 cm away from the ridge surface, in a row-applying manner. According to the characteristic of the peanuts adsorbing the fertilizer, the method increases the contact range of peanut root systems / pods and the fertilizer through the layered fertilization mode, that is, the fertilizer is applied to different soil layers in dispersed and row-applying manners, so that the absorption and utilization of the fertilizer are improved, the utilization rate of the fertilizer is increased, the development of the peanut root systems and root nodules is promoted, the problems of low utilization rate of the fertilizer, rotten fruits and reduced yield of the peanuts, caused by high concentration of fertilizer in the conventional fertilization method, are avoided, the yield and quality of the peanuts are prominently improved, and the product cost is reduced to a certain degree.

Description

Technical field [0001] The invention belongs to the technical field of peanut planting, and in particular relates to a fertilization method for peanuts scattered, packed and seeded in layers. Background technique [0002] The traditional peanut planter fertilization is to apply all the fertilizer in the form of strip application in the soil layer 5-7cm deep from the center of the ridge to the surface of the ridge. [0003] The traditional peanut planter fertilizes because all the fertilizer is concentrated in the 5-7cm depth of the center of the ridge, this fertilization method has some disadvantages: one is that the fertilizer is too concentrated, and the contact surface between the fertilizer and the root system and the pod is small, which is not conducive to the effect of the root system and the pod on the fertilizer. Therefore, the fertilizer utilization rate is low, especially for the phosphate fertilizer with little mobility in the soil, the plant stubble utilization rate is ...
