Hidden layer permanent drainage ditch for farm flourishing

Abstract

The invention discloses a hidden layer permanent drainage ditch for farm flourishing, comprising an isolation layer, a first filter layer, a second filter layer and a third filter layer which are orderly arranged from top to bottom, wherein the isolation layer is made of straw or stalk; the first filter layer is made of small stones; the second filter layer is made of small stones or medium stones; the third filter layer is made of large stones; a soil cultivation layer is covered on the isolation layer; a bracket is arranged between the third filter layer and the bottom of the ditch; a gutterway through which the water can flow is formed between the bracket and the bottom of the ditch; a plurality of water gaps or holes, which are transparent up and down are distributed in the bracket. The hidden layer permanent drainage ditch has the advantages of being lasting in drainability, smooth in water, convenient to build, and firm and durable; overground and underground water levels are effectively reduced; time and labor are saved.

Description

technical field [0001] The invention relates to an agricultural production water supply and drainage regulation system, in particular to a submerged permanent drainage ditch for high-yield farmland. Background technique [0002] At present, in the process of agricultural planting such as rice planting, when transplanting rice seedlings in the farmland to plant rice, it is 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. , rooted in the needs of the growth of strong plants, and at the same time these several tasks are repeated common operations, time-consuming and labor-intensive, the efficiency is low, and the wrong farming time leads to low yields of agricultural products. And because the farmland drainage system cannot reduce the ground and underground water levels in time, increase the undergr...

Problems solved by technology

[0002] At present, in the process of agricultural planting such as rice planting, when transplanting rice seedlings in the farmland to plant rice, it is 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. , rooted in the needs of the growth of strong plants. At the same time, these tasks are frequently used repeatedly, which is time-consuming and labor-intensive, and the efficiency is low. Mistakes in farming time lead to low yields of agricultural products.

And because the farmland drainage system cannot reduce the ground and underground water levels in time, increase the underground air circulation, and promote the vigorous development of the root system of the crops, so that the crops have insufficient resistance to diseases and insect pests and lodging.
