High-efficiency utilization of natural precipitation in forest and fruit fields and weed suppression device and method

Abstract

The invention discloses a device for high-efficiency utilization of natural precipitation in forest and fruit fields and for weed control. A rain-gathering and grass-suppressing cover plate and a protective cover plate arranged on both sides of the rain-collecting and grass-suppressing cover plate are both light and water-impermeable solid dense plates. Its use method is as follows: A. digging a seepage and water-retention ditch along the bottom of the trunk of the forest / fruit tree; B. the soil dug out in step A is piled up into a supporting mound and compacted; C. on the supporting mound obtained in step B, a rain-collecting mound is fitted and laid. Grass unit, that is. The invention can collect rainwater for efficient utilization, reduce ineffective soil evaporation, have excellent weed control effects, and at the same time have a high degree of compatibility with the mechanization of modern agriculture and the automation of water and fertilizers.

Description

technical field [0001] The invention relates to the technical field of hydrology and geography, in particular to a device and method capable of realizing efficient utilization of natural precipitation in forest and fruit fields and at the same time having a weed suppression effect, which is suitable for the North China Plain, especially for areas with annual rainfall less than 500mm. Background technique [0002] With the implementation of the five national forestry projects, the forest area in our country is growing rapidly. Forest belts are planted with a wide row spacing, generally about 2-4 meters, and working equipment can be walked between the rows. Most of the ground is bare, and the ineffective evaporation of the soil is very large, especially in the Bohai Rim area where the soil salinization is serious. With the evaporation of the soil, the salt in the soil rises with the evaporation, which is prone to soil salinization; and weeds are overgrown in the large row spac...

Problems solved by technology

Forest belts are planted with a wide row spacing, generally about 2-4 meters, and working equipment can be walked between the rows. Most of the ground is bare, and the ineffective evaporation of the soil is very large, especially in the Bohai Rim area where the soil salinization is serious. The evaporation of the soil, the salt in the soil rises with the evaporation, and the soil salinization is prone to occur; and weeds are overgrown in the large row spacing, which requires frequent manual weeding or herbicide control, which is labor-intensive and time-consuming
