Description

Micro-soil-preparation drought-resisting operation device combined with no-tillage corn seeder and application method

Technical Field

The invention belongs to the technical field of agricultural machinery, and particularly relates to a micro-soil preparation drought-resisting operation device combined with a corn no-tillage seeder and an application method.

Background

Corn is used as an important grain crop and is also one of essential raw material crops in food, medical health, light industry and chemical industry. Therefore, the corn yield guarantee has great significance for guaranteeing national food safety and social stability and harmony.

Jilin province is the main producing area of spring corn in China, and plays a significant role in the aspects of per unit yield level, commercialization rate and the like. However, for different ecological areas of Jilin province, the yield per unit level is obviously different, especially for wide western arid areas and semi-arid areas, the method is limited by rainfall and the like, drought and rain in the sowing period are main reasons for restricting the sowing quality, seedling shortage and ridge breaking phenomena with different degrees can be caused in general years, the yield loss is over 10 percent, and the yield loss can reach 30 percent in particularly arid years. For example, severe spring drought in 2018 causes that the sowing is delayed for 2-3 weeks than before, and serious influence is brought to the unit yield of regional corns. Therefore, improving the drought-resistant sowing quality of the corn is a main subject for the production of the corn and other crops in the area.

With the improvement of science and technology, the improvement of regional agricultural production level and the application of some major agricultural technologies obviously improve the drought-resistant sowing capacity of the corns. For example, by means of breeding, some varieties with strong drought resistance are bred, and the application of some protective farming measures such as mulching film mulching and water and fertilizer integration technology, no-tillage seeding and soil movement reduction plays some positive roles in improving the drought resistance of regional crop production. However, for the production of crops in large area, the traditional breeding cycle is long, and many limitations in disease resistance, insect resistance, even ecological adaptability and the like need to be considered, so that the application of the technology is limited; the plastic film mulching and water-fertilizer integration technology is difficult to popularize and apply in a large area due to the limitation of agricultural infrastructure construction and capital investment, agricultural production comparative benefits, farmer cognition, behavior selection and the like, and the plastic film mulching and drip irrigation pipe has certain environmental pollution risk after being used for a long time. Therefore, the development of a matching machine of the corn no-tillage planter, which is simple in operation, strong in practicability, green and environment-friendly, and obvious in effect, has important significance for drought-resistant cultivation of large-area agricultural production in regions.

Through the use of ploughing seeder antithetical couplet and slightly preparing drought resisting operation device, its apparent soil that lets the earth's surface push away disperses outside the seedling area, guarantee to sow earth's surface soil humidity after the plastic a little promptly, simultaneously with the formation bellied soil structure outside the seedling area, be favorable to growing period seedling area collection rain, thereby the utilization efficiency to the rainfall nature has been improved, but when the in-service use, the distance between two furrow openers is not convenient for adjust, and the height of furrow opener is also not convenient for adjust, be not convenient for actual operation, influence work efficiency.
