A method for planting summer corn with a grass square sand barrier type crop precision on-demand device

Abstract

The invention discloses a method for planting summer corn with a grass square sand barrier type crop precision on-demand device, including (1) preparation before sowing, including selection of fine varieties, selection of seeds, drying of seeds, planting methods, and selection of plots; (2) Sowing with a grass grid sand barrier type crop precision on-demand device; (3) After the maize emerges, check seedlings, replenish seedlings, thin out seedlings, and stabilize seedlings. When sowing, use the method of sowing first and then watering for irrigation and intertillage , fertilization, weeding, and lodging prevention; (4) Use chemicals to prevent and control corn leaf spot, aphids, and corn borer pests; (5) When summer corn bracts turn white, the upper mouth is loosened, and a black layer at the base of the grain appears, When the milk line disappears, it can be harvested. The invention combines the advantages of planting grass grid sand barriers in desert areas, and the concave grid can collect rainwater, reduce ground wind speed, reduce water evaporation, and improve the drought tolerance of corn to a certain extent, thereby increasing crop yield.

Description

technical field [0001] The invention relates to a method for planting summer corn, in particular to a method for planting summer corn with 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 th...

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
