Straw-checker sand-barrier type crop precision dibble seeding device

Abstract

The invention discloses a straw-checker sand-barrier type crop precision dibble seeding device. The straw-checker sand-barrier type crop precision dibble seeding device comprises a connecting rod mechanism, a seeding box and a grid, wherein the connecting rod mechanism is arranged above the seeding box; a steel wire rope is connected with and arranged at the bottom part of the connecting rod mechanism, and is positioned in the seeding box; the connecting rod mechanism can penetrate through the seeding box to move up and down; a spring opening is arranged on the side surface of the seeding box;a cross rod is fixedly arranged in the spring opening; one end of the cross rod penetrates through the steel wire rope; the bottom part of the steel wire rope is fixedly arranged on a fertilization adjusting button; a spring, located outside of the seeding box, is connected with and arranged at the other end of the cross rod; the tail end of the spring is connected with a seeding head located atthe bottom part of the seeding box; and a grid is arranged below the seeding head and fixedly connected with the seeding box. According to the invention, advantages of planting of straw-checker sand barriers in a desert area are combined; rainwater is collected in a concave grid pressed at the bottom part of the device; the ground wind speed is reduced; water evaporation is reduced; the drought resistance of plants is improved to a certain extent; the problem that plant growth is affected due to small amount of precipitation is solved; and thus, the crop yield is increased.

Description

technical field [0001] The invention relates to a crop on-demand device, in particular to a grass square sand barrier type crop precision on-demand device. Background technique [0002] my country is a country with a shortage of water resources, and water resources have the characteristics of uneven distribution in time and space, which is not suitable for the regional distribution of cultivated land and population. The total amount of water resources in northern my country only accounts for 14.4% of the national total, but the cultivated land area accounts for 58.3% of the national total. At the same time, due to the strong influence of the monsoon climate, the distribution of precipitation in my country is very uneven and the inter-annual variation is large. In addition, the development and utilization of water resources in my country is also uneven, which has caused relatively water shortages in my country, especially in the Loess Plateau in Northwest China and North Chin...

Problems solved by technology

At the same time, due to the influence of terrain, the altitude difference is large, there are many mountainous areas and it is not easy to store rainfall in mountainous areas, and the evaporation is large

Therefore, most of the small amount of agricultural water in mountainous areas is mainly transported by manpower, resulting in high agricultural production costs and low work efficiency, which to a certain extent has greatly affected and hindered agricultural production.

Of course, the local agricultural water use is mainly maintained by precipitation, but the mountainous terrain is rugged and difficult to store precipitation. In addition, the utilization rate of natural precipitation in my country's farmland is low, only reaching 56%. The efficiency of agricultural water use is not high, and the water use efficiency of farmland is 0.6- 0.75kg / m3, the technological transformation centered on water saving in these areas is an important measure to solve the problem of water shortage in Northwest China and promote the development of agricultural modernization
