Automatic water supplementing type greenhouse soil structure

Abstract

The invention belongs to the technical field of agriculture, and particularly provides an automatic water supplementing type greenhouse soil structure. The greenhouse soil structure comprises a header tank, a water storage tank and a soil layer structure, wherein the bottom of the soil layer structure is sealed, the header tank is arranged at the bottom outside the soil layer structure, the water storage tank is isolated from the soil layer structure, water absorbing sponge is arranged in the water storage tank, the other end of the water absorbing sponge is arranged in a peripheral tank in the soil layer structure, and the peripheral tank is isolated from the soil layer through an obstructing net. The soil layer structure is capable of fully saving water and achieving automatic adjustment of water in soil in a greenhouse. Soil updating and replacement are convenient.

Description

Technical field [0001] The invention belongs to the field of agricultural technology, and particularly relates to an automatic water supplement type greenhouse soil structure. Background technique [0002] With the widespread popularity of greenhouses, there are more and more crops in the greenhouses, and the nutrient content in the soil in the greenhouses will change after years of growth. Although fertilization can be used to improve the soil, the soil quality will still decline; the existing The water control of the soil layer in the greenhouse is also mainly carried out by irrigation, and this method has a large human factor. If the water volume is not controlled well, it will cause water waste and also have a negative effect on the respiration of crop roots. . Summary of the invention [0003] In view of this, the present invention aims to propose an automatic water replenishment greenhouse soil structure to solve the problems in the prior art, realize the automatic adjustme...

Problems solved by technology

[0002] With the widespread popularity of greenhouses, more and more crops are in the greenhouses, and the nutrient content in the soil in the greenhouses after many years of growth will change. Although the soil can be improved by fertilization, the soil quality will still decline; the existing The moisture control of the soil layer in the greenhouse is also mainly carried out by irrigation, and this method has relatively large human factors. If the water volume is not well controlled, it will cause waste of water, and at the same time, it will also have a negative effect on the respiration of crop roots.
