Agricultural water retention mulching film

Abstract

The invention discloses an agricultural water retention mulching film, and belongs to the field of agriculture. The agricultural water retention mulching film comprises a positioning film, a water seepage layer is fixedly connected to the positioning film, a plurality of uniformly distributed water through holes are dug in the water seepage layer, a water retention film is fixedly connected to thewater seepage layer, and the water retention film comprises a plurality of horizontal films. A folding film is arranged between every two adjacent horizontal films, binding belts are connected between the folding film and the horizontal films, the binding belts are fixedly connected with the water seepage layer, fixing buckles are arranged in the folding films, the inner walls of the two ends ofthe folding films are connected through the fixing buckles, the folding films are filled with a plurality of water retaining balls, and the light transmission of the film can be guaranteed in a normalstate. When the moisture in the soil is excessively evaporated, the mulching film can be expanded to release the water retaining balls to recover the moisture, evaporation loss of the soil moisture is effectively prevented, meanwhile, the falling water retaining balls and the expanded folding films shield the surface of the soil, irradiation of sunlight to the soil is further reduced, and evaporation of the soil moisture is prevented.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an agricultural water-retaining plastic film. Background technique [0002] Mulch film is the ground covering film, covering the ground, which can increase soil temperature, maintain soil moisture, improve fertilizer efficiency, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc., and promote plant growth. Plastic film mulching cultivation is an important means in agricultural production. The use of plastic film mulching can meet the needs of crop warming, moisture conservation, and fertility maintenance. It is mainly used for early mulching of crops in northern, arid, and cold regions, as well as windproof and sand-fixing. Quality, early maturity and other functions. [0003] Among the functions of agricultural mulch, water retention is a very important item, and water retention is also an important indicator for evaluating s...

AI Technical Summary

Problems solved by technology

[0004] The water retention performance of ordinary agricultural mulch film is not good, especially in the north where there is little rain and aridity, this problem is even more prominent

Existing liquid mulch products have low film strength, cracking after laying on the surface, ventilation and ventilation, etc., and poor water retention, heat preservation and fertilizer retention effects
