Precise water-supplementing and subsoiling machine and water-supplementing method thereof

Abstract

The invention discloses a precise water-supplementing and subsoiling machine and a water-supplementing method thereof, and belongs to the technical field of agricultural machines. A subsoiling machineis used to carry a water supplementing system and a soil moisture detecting device in order to simultaneously carry out subsoiling operation and water-supplementing operation on land; the soil moisture detecting device arranged at the lower end of a subsoiling shovel is used to quickly, conveniently and accurately detect the soil moisture condition of a plow bottom layer, and then a control unitcontrols the water supplementing system to perform precise water supplementation according to a predetermined water supplementing program; water is atomized by an atomizing nozzle and then is sprayedon the broken soil in the plow bottom layer, so water supplementing is realized during subsoiling, and uniform water supplementation is achieved; and the good water supplementing effect and avoiding of the waste of water resources are achieved.

Description

technical field [0001] The invention specifically relates to a precision water replenishment subsoiler and a water replenishment method thereof, belonging to the technical field of agricultural machinery. Background technique [0002] In terms of agricultural production, in order to obtain high grain yields and harvests, not only high-quality seeds, sufficient fertilizers, and methods of controlling pests and diseases are required, but also advanced and applicable mechanization technology as support; [0003] The meaning of mechanical subsoiling technology: refers to the mechanized technology of using different power machinery to support corresponding subsoiling machinery to complete farmland subsoiling operations; the purpose of mechanical subsoiling is to loosen the soil, break the bottom of the plow, and increase the speed and quantity of rainwater infiltration , reduce runoff, reduce water evaporation loss; mechanical deep loosening of soil is actually a technological re...

Problems solved by technology

[0004] The facts of agricultural production tell us that one of the most important factors restricting the increase in grain production is the quality of the soil; according to surveys, in the past 30 years, most of the land in our province has been dominated by traditional farming methods, that is, small-scale agricultural machinery operations. As a result of cultivation, the soil plow layer is only about 12-15 cm, the soil is hardened severely, and the resistance continues to increase. It hinders the penetration of water vapor from the top and bottom of the soil and the storage of natural precipitation. The continuous operation of small agricultural machinery has also led to a large reduction of earthworms and other organisms in the soil, the destruction of soil capillaries, and the destruction of soil nutrient transport capacity, making it difficult to maintain normal growth of plants. Demand for water, fertilizer, air, and heat; such as figure 1 Shown is a schematic diagram of the above-mentioned soil structure; according to measurements, the plowing depth of the small four-wheel machinery for stubble removal is 6-10cm, and the multi-functional compound soil preparation machine is only 12-16cm; this has led to the increase of soil drought year by year, a vicious cycle, crops It can only grow in the narrow space of the interlayer, there is no room for root development, and nutrients cannot be absorbed, resulting in poor growth of crops, insufficient wind resistance, drought resistance, and disease resistance; soil compaction, crop roots cannot be deeply penetrated, it should be said that the quality of cultivated land has declined , has become a basic obstacle to improving the comprehensive agricultural production capacity
