Farmland water filtering control and soil amelioration desalination persistent blind drain

Abstract

The invention relates to a farmland water filtering control and soil amelioration desalination persistent blind drain which comprises an isolation layer, a first filtering layer and a second filtering layer which are arranged from top to bottom in sequence. The isolation layer is formed by an upper straw or crop stalk layer and a lower filter screen, the first filtering layer is formed by small stones, the second filtering layer is formed by middle stones, the isolation layer is covered with a soil ploughing layer, a drainage pipeline is arranged between the interior of the second filtering layer and the bottom of the drain and formed by multiple sections in a connected mode, and a gap exists between every two sections. By means of the farmland water filtering control and soil amelioration desalination persistent blind drain, the water levels overground and underground can be lowered in time, the blind drain filters soil water of the farmland planting surface, the filtered water is drained, the quality of the drained water is improved, the water level of soil of the hidden layer, and deep desalination and dealkalization on saline and alkaline farmland can be achieved; the construction is easy and rapid, and the cost is low.

[0002] At present, in the process of planting crops in agriculture, when sowing rice and barley in the farmland, it is often necessary to keep a good row spacing (ditch spacing) every season when transplanting seedlings, or after pulling out seedlings and transplanting plants in the middle, dig trenches and move soil to achieve drainage for crop growth. At the same time, these tasks are often used repeatedly, which is time-consuming, labor-intensive 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 underground water levels in time, increase the underground air circulation, and promote the vigorous development of crop root systems, so that the crops have insufficient resistance to pests and diseases and lodging. Modern agricultural planting urgently needs a It can not only play a good role in filtering and controlling water, but also improve the discharge water quality and reduce the water level of the subsurface layer. The saline-alkali field can be deeply desalinated and de-alkalied without delaying the farming time. It is a scientific and innovative modern agricultural technology management system that is convenient for management.
