Quantitative fertilizing method of crop chemical fertilizers

Abstract

The invention relates to the field of quantitative fertilizing of chemical fertilizers, in particular to a quantitative fertilizing method of crop chemical fertilizers. The method involves a main body, a feeding mechanism, excavating mechanisms, a rotating shaft, a discharging mechanism, a connecting mechanism, a driving mechanism and an adjusting mechanism. According to the method, when crops need to be fertilized, the excavating mechanisms are disassembled according to the distance between the crops; the adjusting mechanism is rotated to adjust the distance between one ends of the excavatingmechanisms and the rotating shaft to enable the arc-shaped distance between every two adjacent excavating mechanisms is equal to the distance between the crops; after one excavating mechanism enterssoil, the excavating mechanisms drive the driving mechanism to rotate, the driving mechanism drives the bottom ends of the excavating mechanisms to be opened in soil, and grooves obtained by excavating are located in one sides of the crops; and meanwhile, the driving mechanism rotates to drive the discharging mechanism to rotate to enable the chemical fertilizers in the discharging mechanism to enter the grooves, and the volume of the chemical fertilizers added into the grooves each time is equal to the volume of the interior of the discharging mechanism, so that the quantitative fertilizers are added into the grooves.

Description

technical field [0001] The invention relates to the field of chemical fertilizer quota fertilization, in particular to a method for crop chemical fertilizer quota fertilization. Background technique [0002] When the soil cannot provide the nutrients needed for the growth and development of crops, the behavior of artificially supplementing nutrients to crops is called fertilization. Increase soil nutrients No matter the application of organic fertilizers or inorganic fertilizers can increase soil nutrients. Most of the inorganic fertilizers are easy to dissolve, and the crops can absorb them immediately after application, except that they are partially absorbed by the soil. For organic fertilizers, except for a small amount of nutrients that can be directly absorbed by crops, most of them must be decomposed by microorganisms before crops can use them.

AI Technical Summary

Problems solved by technology

[0003] When planting crops in mountain terraces, the roads are impassable, the area of ​​mountain terraces is small, and large fertilizer machines cannot enter the fields for fertilization, and farmers have a weak concept of reasonable fertilization, and they have insufficient control over the amount of chemical fertilizers required for the growth of each crop. Excessive application of chemical fertilizers, and excessive application of chemical fertilizers, on the one hand, will make crops prone to lodging, resulting in reduced grain production; , easily infested by diseases and insect pests; if the amount of chemical fertilizers is not controlled for a long time, it is easy to cause accelerated soil acidification, soil nutrient imbalance, accelerated soil heavy metals and toxic elements, which is not conducive to the growth of crops; when crops grow, need Fertilize crops, and different crops have different distances. The fertilization tool is blocked by tall crops, and it is impossible to fertilize flexibly. During the movement of the fertilization tool, it is easy to damage the crops.
