A corn intelligent sowing and fertilization control system and control method

Abstract

The invention relates to the technical field of agricultural machinery and especially relates to an intelligent maize sowing and fertilizing control system and control method. The system comprises a central control system, a sowing subsystem and a fertilizing subsystem, which are arranged in each sowing and fertilizing machine. The fertilizing subsystem comprises a fertilizing flow control device, a fertilizing amount detection device, a fertilizer soil entering detector, a fertilizer depth measurement device and a soil fertilizer content detection device. Automatic positioning and sowing of seeds and fertilizer can be realized, and actual sowing depth of the seeds and fertilizer and soil fertilizer content can be detected; and substandard sowing points can be positioned and compensated in time.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an intelligent corn sowing and fertilization control system and control method. Background technique [0002] With the development of agricultural machinery automation, farming operations such as sowing and fertilizing are gradually replaced by machines, which reduces the burden on farmers and effectively improves the efficiency of farming. Seed and fertilizer simultaneous sowing technology, as a product of intelligent machinery, is widely recognized because it can apply fertilizer at one time while sowing, eliminating the traditional multiple fertilization process. However, in actual use, especially when corn is planted, due to factors such as uneven surface soil and mechanical walking bumps, there is an error between the actual position of the seed or fertilizer and the distance from the surface and the theoretical range. These errors are likely to affect the gr...

AI Technical Summary

Problems solved by technology

However, in actual use, especially when corn is planted, due to factors such as uneven surface soil and mechanical walking bumps, there is an error between the actual position of the seed or fertilizer and the distance from the surface and the theoretical range.

These errors are likely to affect the growth of later plants

The existing seeding and fertilizing machines do not record the error and the coordinate position where the error exists, so that when there is a problem with plant growth, the cause cannot be found out in time, and the timing of treatment is delayed

[0003] In addition, due to the influence of uneven soil or the structure of the machine itself, the fertilization process of the existing fertilizer applicator will be interrupted when it is moving, and fertilization cannot be done continuously, resulting in uneven fertilization, and the content of nitrogen, phosphorus and potassium in the field cannot be precisely controlled
