Device and method for efficiently utilizing natural rainfall of forest and fruit land and inhibiting and removing weeds

Abstract

The invention discloses a device for efficiently utilizing natural rainfall of forest and fruit land and inhibiting and removing weeds. The device structurally comprises a plurality of rain collecting and weed inhibiting units which are sequentially laid. Each rain collecting and weed inhibiting unit comprises a rain collecting and weed inhibiting cover plate with the middle high and the two sides low, and protective cover plates arranged on the two sides of the rain collecting and weed inhibiting cover plate. The rain collecting and weed inhibiting cover plates and the protective cover plates are all solid thick plates impermeable to light and water. The using method of the device includes the steps that A, a water seepage and retention trench is excavated along the bottom of a tree trunk of a forest/fruit tree; B, soil excavated in the step A is piled into supporting soil mounds which are tamped; C, the rain collecting and weeding inhibiting units are laid on the supporting soil mounds which are obtained in the step B in a matched mode, and then the device is obtained. The device can collect rainwater and efficiently utilize the rainwater, ineffective evaporation of soil is reduced, a good weed inhibiting and removing effect is achieved, and meanwhile the device has high compatibility with mechanization and automatic watering, fertilization and insecticide application of modern agriculture.

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 500 mm. 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 spa...

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
