Abstract
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...
Examples
Embodiment Construction
[0025] Please refer to figure 1 , figure 2 As shown, it is the submerged farmland high-yield permanent drainage ditch of the present invention, including an isolation layer 1, a first filter layer 2, a second filter layer 3, and a third filter layer 4. The isolation layer 1 is made of straw or straw Composition, its thickness is 50-80mm, this layer mainly plays a role in filtering and blocking sediment and impurities, the first filter layer 2 is made of small stones or stone flakes with a thickness of 100-180mm. The second filter layer 3 is made of medium stones or one-inch-sized stones, 100-180mm, and the third filter layer 4 is made of large stones or large stone flakes or stones of the size of a goose egg. It can also be used to remove walls and bricks and remove cement pavement The broken block is composed of broken stones, and its thickness is 100-180mm. The thickness of the fourth filter layer becomes 90-180mm. After passing through the third and fourth filter layers, ...
