Description

Pesticide spraying device and method for improving adhesion on blades after pesticide spraying

Technical Field

The invention belongs to the field of agricultural machinery, relates to a pesticide spraying technology, and particularly relates to a pesticide spraying device and a method for improving the adhesion force of pesticide sprayed on blades.

Background

The annual chemical pesticide use area of China is 2.8 hundred million hm²In the above, about 70% of chemical pesticides are wasted in an application amount of 50 to 60 ten thousand tons, and the pesticides do not directly act on a control object and are difficult to attach to leaves, which is a main cause of waste. The conventional pesticide feeding mode is generally large-area, wide-range and average feeding. The throwing mode is simple to operate and has certain prevention and control effect. But neglects the spatial distribution of the pests; taking cotton crops as an example, cotton aphids and cotton bollworms generally inhabit the lower surfaces of the leaves, and the traditional pesticide putting mode is difficult to directly act on the inhabiting positions of pests and has poor pesticide effect. Meanwhile, in order to reduce the economic loss of crops caused by plant diseases and insect pests, a grower usually uses a large amount of pesticide frequently, so that a large amount of pesticide is wasted; in addition, many plant leaves have natural hydrophobicity, and the plant epidermal cells are covered with a hydrophobic layer consisting of lipophilic plant wax, so that pesticides are difficult to adsorb on the surfaces of the leaves. Part of pesticide falls off naturally or is changed into runoff by rain washIn part, can lead to contamination of soil and water resources. In addition, the root system also absorbs residual pesticides dissipated in soil and irrigation water, so that pesticide residues in crops are accumulated, the quality of agricultural products is reduced, and finally the residues enter a food chain to threaten the health of people. Therefore, the use of the pesticide is reduced, and the utilization rate of the pesticide is improved.

Disclosure of Invention

The invention aims to solve the problems that the pesticide utilization rate is low and the pesticide is easy to pollute soil when falling off plants in the soil at present.
