Replacing herbicides with high technology to ensure "double safety" of grain production food

Using high technology to replace herbicides to ensure the "double safety" of grain production food

"The new pneumonia epidemic is spreading rapidly around the world, some countries regions are strengthening trade control. It is also a severe test for China's food security." For wheat production, spring is the key time to increase production ensure production. However, in the face of the impact of a large area of weeds in the field, large growers face the shortage of agricultural labor force, often use excessive herbicides to solve the problems in food production.

"At present, the use of herbicides has accounted for 60% of the amount of pesticides used, has become the main source of agricultural non-point source pollution. It is urgent to solve the problems through agricultural technological innovation." Professor Zhang Ruihong said.

Wheat, rice corn grow in the field, a lot of weeds will be generated in the field, this time weeding is needed. During the period of traditional agricultural operations, it mainly depends on manual removal. "But since the 1980s, due to the massive transfer of rural labor, the continuous development of pesticides fertilizers, stem leaf treatment agents, contact herbicides, etc. have begun to be used in large quantities, the dosage is still high." To solve the problem of herbicide pollution, has been It is imminent to become a major event in China's environmental governance.

Experts introduced that the residues toxicity of herbicides are much more much stronger than insecticides. Excessive use of herbicides in large quantities causes great harm to crops the environment. For example, bensulfuron-methyl is a systemic, conductive sulfonylurea herbicide applied in large areas around the world, which is very likely to cause potential harm to the ecological environment, food crop yield, food safety the environment.

In addition, when weeding controlling pests diseases, the large-scale domestic use is still mainly manual motorized fog sprayers other small spraying machinery, which has poor operating accuracy a large diameter of fogged droplets, the droplets are easy to roll off the blade surface, resulting in Nearly 70% of pesticides are lost to the soil, causing large-scale environmental pollution.

In the opinion of experts, the key to solving the problem of agricultural non-point source pollution is to accelerate the integration of agricultural technology, mechanization of the planting process, production management in accordance with the principles of "equal emphasis on increasing production efficiency, supporting good varieties good laws, combining agricultural machinery agronomy, producing ecology. Informatization, eco-environmental protection greening promote the prosperity development of China's crop cultivation science, effectively guarantee the quality safety of China's agricultural products the sustainable development of crop production in the new period.

In recent years, with the rapid rise vigorous development of Beidou Navigation, artificial intelligence, big data, cloud computing, Internet of Things, advanced manufacturing other technical fields, China is building an innovative industrial chain of multi-disciplinary integration of agricultural machinery technology, a group of independent innovations The achievements are overturning the traditional production methods of grain production food, spawning a number of new industries, new models, new formats.
