Modern agricultural planting hidden layer filter and drainage and water and soil improving high-yield technology blind drain

Abstract

The invention relates to a modern agricultural planting hidden layer filter and drainage and water and soil improving high-yield technology blind drain. An isolation layer, a first filter layer, a second filter layer, a third filter layer, a fourth filter layer and a fifth filter layer are sequentially arranged below a soil plough layer from top to bottom, wherein the first filter layer is composed of coarse sand, the second filter layer is composed of coarse sand and melon seed-shaped gravels or small gravels, the third filter layer is composed of melon seed-shaped gravels or small gravels, the fourth filter layer is composed of inch gravels or medium gravels, and the fifth filter layer is composed of large gravels. A laying layer is arranged on the upper layer of the isolation layer, and a filter net is arranged on the lower layer of the isolation layer. The laying layer is composed of mountain grass or bamboo or leaves or fruit shells or straw or halm or husk. A pipeline with no filter net or a drainage pipeline wrapped by a filter net are arranged in the fifth filter layer and is higher than the horizontal plane of water flow in a canal or river, and a plurality of small holes are evenly formed in the pipe body for water flow. Water in soil on a farmland planting surface layer or hidden layer is drained after being filtered, the drained water quality is improved, the hidden layer soil water level is lowered, and the deep desalination and dealkalization effect can be achieved for salt and alkali farmland. The modern agricultural planting hidden layer filter and drainage and water and soil improving high-yield technology blind drain is easy to construct, practical, durable and low in cost.

Description

technical field [0001] The invention relates to the application technical field of planting crops for agricultural production and controlling saline-alkali land and farmland water and soil regulation in my country, and more specifically relates to a modern agricultural planting latent layer filtering and drainage improving water and soil high-yield technology culvert. Background technique [0002] my country has a vast land, a large population, a large demand for food, a large area of ​​farmland, and a large area of ​​saline-alkali land that has not been transformed into fertile land and cannot grow crops.

[0002] my country has a vast land, a large population, a large demand for food, a large area of ​​farmland, and a large area of ​​saline-alkali land that has not been transformed into fertile land and cannot grow crops. It is urgent to innovate a modern agricultural planting filter drainage improvement water and soil application technology system, especially The reason is that agricultural planting management has not changed for thousands of years. The old management methods can no longer keep up with the needs of scientific planting. Agricultural planting management is time-consuming, laborious and inefficient. Mistakes in farming time lead to low yields of agricultural products, which are no longer suitable for the rapid development of modern agriculture.

And because the drainage system of farmland, especially some cold-soaked farmland and low-lying farmland, cannot reduce the ground and u
