Fertigation control system

Abstract

The invention relates to a fertigation control system for planting crops. The fertigation control system comprises a fertilizer container, a water source device, a control system and the like, wherein the control system comprises a controller and control branches, the controller is used for respectively controlling startup devices of the fertilizer container and the water source device by the control branches, wherein a fertilizer outlet pipe of the fertilizer container is converged with a water outlet pipe of the water source device and is then branched into a plurality of irrigation pipes communicated to an irrigation region. The fertigation control system disclosed by the invention can provide a fine fertigation scheme according to program control and soil situations and growth requirements of different stages of crops, is capable of sufficiently absorbing moisture and nutrients and cannot cause soil pollution.

Description

technical field [0001] The invention relates to an irrigation and fertigation control system for planting crops. [0002] Background technique [0003] The variety of crops is diverse, and the types and time intervals of fertilization are different for different varieties. However, in most cases, it is difficult for farmers to fertilize finely. First, the proportion of fertilizers is not as accurate as that of experts. Different growth stages require fertilization, and the labor intensity is also very high. Conventional fertilization is often one-time fertilization, not only excessive water loss, but also oxidation of fertilizers in the air and residues of unabsorbed fertilizers on the soil surface, which is not conducive to environmental protection, nor does it take advantage of the absorption of fertilizer nutrients by crops. [0004] The current fertilization system used in agriculture generally has relatively expensive facilities and is suitable for farms or large-scal...

[0003] The variety of crops is diverse, and the types and time intervals of fertilization are different for different varieties. However, in most cases, it is difficult for farmers to fertilize finely. First, the proportion of fertilizers is not as accurate as that of experts. Fertilization is required in different growth periods, and the labor intensity is also very high

Conventional fertilization is often one-time fertilization, not only excessive water loss, but also oxidation of fertilizers in the air and residues of unabsorbed fertilizers on the soil surface, which is not conducive to environmental protection, nor does it take advantage of the absorption of fertilizer nutrients by crops

[0004] The current fertilization system used in agriculture is generally expensive in facilities and is suitable for farms or large-scale fertilization, but it is not suitable for the system of family responsibility fields in rural my country and the diversification of planting varieties.

Moreover, the climate and soil conditions in various regions of our country vary greatly, as well as environmental changes. The existing knowledge level of agricultural personnel is relatively backward. Based on the past experience of agricultural personnel, the decision to purchase fertilizers, fertilization time and amount of fertilizers will affect the planting effect of crops and The grasp of fertilizer utilization rate is not scientific, which may lead to inaccurate fertilization time and amount, fertilizer consumption and labor waste.
