[ China Agricultural Machinery Industry News ] As green agriculture has become the general direction of China's agricultural development, China has taken a crucial step towards the active transformation of ecologically sustainable agriculture. The long-term overdraft of agricultural resources, the excessive use of pesticides and the lack of comprehensive utilization of agricultural wastes, the solution to the two problems of resources and environment is becoming more and more urgent.
Modern agricultural green transformation plant protection machinery is a breakthrough
Water is the "lifeline" of agriculture, and Fertilizer is the "food" of crops. Pesticides are the "drugs" for crops to prevent and cure diseases. These three are several important issues that must be faced in the modern development of modern agriculture.
Water-saving irrigation is a common topic in modern agriculture. The use of water resources is inseparable from advanced irrigation equipment. In the apple park using drip irrigation equipment, it takes only 15 to 20 square meters of water to cast an acre of land, and 80% less water than flood irrigation. The original 100-acre orchard had to hire more than a dozen people to take care of it. Now only two people are used, and the yield per mu has increased by 20%.
For the utilization of chemical fertilizers, “deep application of chemical fertilizers†is an important technical means, which can greatly reduce the volatilization and loss of fertilizers, and the deep application of chemical fertilizers must rely on agricultural machinery. By contrast, after deep application of chemical fertilizer, not only the fertilizer is saved by nearly 20% per mu, but also the yield is increased by more than 10%.
Pesticide has received special attention because of the quality and safety of agricultural products. To reduce the amount of pesticides used, it is necessary to give "bullets" a "good gun." Plant protection machinery (unmanned aerial vehicle) is more suitable for spraying, more uniform spraying, stronger penetrating power, and better drug-resisting effect, which can effectively reduce the number of medications and dosage and reduce pesticide residues. China Agricultural Machinery Industry Network and Jiamusi Longyue planted a strong alliance to provide drone operation services for the people of the country, solve security risks and help green agriculture development.
China has comprehensively started the battle for the integration of agricultural resources pollution control. Agricultural machinery (unmanned aerial vehicles), which implements and promotes this strategic initiative, is undoubtedly the key hand and carrier, and is an important breakthrough.
