Machine capable of simultaneously laying anti-seepage and anti-evaporation films on soil bottom layer and surface layer

Abstract

The invention discloses a machine capable of simultaneously laying anti-seepage and anti-evaporation films on a soil bottom layer and a surface layer. The machine comprises a rack, an impact type soilshoveling device arranged on the rack, a separation and filtering device, a soil bottom layer film covering device and a soil surface layer film covering device, wherein the separation and filteringdevice is installed behind the impact type soil shoveling device and is in transmission connection with the impact type soil shoveling device; the soil bottom layer film covering device is arranged below the impact type soil shoveling device; the soil surface layer film covering device is arranged below the separation and filtering device. A mellow soil layer is shoveled and sent onto the separation and filtering device through the impact type soil shoveling device, an immature soil layer below the mellow soil layer exposed from cultivated land, the soil bottom layer film covering device covers the immature soil layer by using the film, soil of the mellow soil layer falls and covers the film of the immature soil layer after being filtered by the separation and filtering device, the soil surface layer film covering device covers the mellow soil layer by using the film, and a sandwich structure is formed. Temperature increase, water retention and fertilizer retention are realized, soil moisture can be prevented from seeping, physical and chemical properties of the soil are improved, the soil fertility is improved, the growth of weeds can be inhibited, and the disease damage can be relieved.

Description

technical field [0001] The present invention relates to the field of agricultural machinery, and more specifically relates to a method of laying an anti-seepage and anti-evaporation film on the bottom layer and surface layer of the soil to effectively improve soil fertility, increase the temperature in the soil, inhibit the growth of weeds, and optimize the physical and chemical properties of the soil. Machinery for disease mitigation. Background technique [0002] With the development of agricultural cultivation technology, plastic film mulching has become one of the key technical measures of dry farming and water-saving agriculture. In recent years, the arid and semi-arid areas of Northwest, North China, Northeast and Southwest China have vigorously promoted the cultivation technology of plastic film mulching, which has effectively improved the level of food production technology, and achieved remarkable results in moisture conservation and temperature improvement, drought...
