A root zone type controllable fertilizer saver

Abstract

The invention provides an adjustable plant root zone fertilizer water irrigation technique device particularly suitable for production of fruit trees such as pomelo trees and jack fruit trees which have well developed root systems, large line spacing and row spacing and the high fertilizer requirement per plant, and during planting of economic plants such as grape trees, banana trees, wax apple trees, mango trees and litchi trees with high fertilizer requirements, fertilizer water irrigation operation of a large batch of plants can be achieved in the mode that a fertilization tank is enlarged according to an equal proportion and the bottom of the fertilization tank is connected with a drop irrigation leather hose. During practical production, the humidity of the rhizospheres of the plants is mainly monitored through humidity probes, a fertilizer water storage tank is controlled to directly convey to-be-applied fertilizer water to the surfaces of the root systems of the plants through root zone contact areas under the condition that the plants are short in water and fertilizer, the diffusion and permeation process of the fertilizer water from soil to the root systems of the plants is greatly shortened, and it is guaranteed that the plants absorb and use the fertilizer water efficiently. A plant root zone type controllable fertilizer economizer reduces losses and waste of soluble fertilizer in the transfer and diffusion process from the soil environment to the root systems of the plants, and fertilizer utilization efficiency is remarkably improved. The root zone type controllable fertilizer economizer can be widely applied to various fields, is convenient to operate, enables the utilization efficiency of the water soluble fertilizer to be improved by more than 20%, saves more than 30% of water, and has broad application and market popularization prospects.

Description

technical field [0001] This patent belongs to the field of planting, and in particular relates to a technique for improving fertilizer and water use efficiency by using a controllable fertilizer and water applicator. Background technique [0002] Fertilizer is an important means of agricultural production and the material basis of crop production. It contributes about 40% to 50% to the increase in grain production. At present, my country's annual chemical fertilizer consumption is about 60 million tons, accounting for more than 30% of the world's total. However, only 28% to 41% of the fertilizers applied to the soil are absorbed and utilized by crops, while most of the rest are left in the soil or transferred to the atmosphere and water bodies, causing a series of environmental problems such as greenhouse gas emissions and water eutrophication. The problem is that the low utilization rate of fertilizers not only causes a lot of losses and waste of resources, but also serious...

AI Technical Summary

Problems solved by technology

Faced with the current dual pressures of food security and resources and the environment, achieving high crop yields, resource efficiency and environmental protection at the same time has become the only way for the development of modern agriculture in my country. , while improving the utilization rate of fertilizers has become an important bottleneck restricting my country's agricultural production

In the current environment, scholars' research on improving fertilizer efficiency mainly focuses on crop growth requirements and scientific fertilization methods, while the technical research and application of matching fertilization to plants through the rhizosphere is still in its infancy
