In-depth implementation of chemical fertilizer reduction and efficiency increase actions to ensure that the utilization rate of chemical fertilizers is increased to over 40% and the negative growth of chemical fertilizer use is maintained. Select 300 counties producing grain, cotton and oil to carry out the pilot project of reducing chemical fertilizer and increasing efficiency, and integrate and promote high-efficiency fertilization technologies such as deep application of rice, simultaneous sowing of corn seed fertilizer and one-time fertilization of wheat, so as to demonstrate and drive the reduction and increase efficiency of chemical fertilizers nationwide.
Continue to promote the cooperation between farmers and enterprises in soil testing and formula fertilization, scientifically formulate large formulas, and promote the landing of formula fertilizer. The pilot implementation scope of replacing chemical fertilizer with organic fertilizer for fruit, vegetable and tea is inclined to the Yangtze River Economic Belt and the Yellow River Basin, and the pilot crops are expanded from apples, oranges, vegetables and tea to other horticultural crops with local characteristics and great fertilizer saving potential.
Carry out in-depth actions to reduce pesticide consumption and increase efficiency, ensure that the utilization rate of pesticides is increased to over 40%, and maintain negative growth in pesticide use. Implement green prevention and control instead of chemical prevention and control, continue to create 100 green prevention and control demonstration counties, promote green technologies such as ecological prevention and control, biological prevention and control and new plant protection machinery, and implement professional unified prevention and control.
In the main grain producing areas and the advantageous areas of fruit, vegetable and tea, we will build a number of full-scale green prevention and control demonstration models to drive large-scale reduction and efficiency increase of pesticides, and strive to achieve a green prevention and control coverage rate of major crop pests and diseases of more than 30%. Strengthen the supervision and inspection of the safe use of pesticides, and increase the investigation and punishment of illegal use of pesticides.
Fertilizer control and synergistic measures
First of all, scientific fertilization is the premise. It is necessary to adhere to the principle of organic-inorganic combination and close coordination of nitrogen, phosphorus, potassium and trace element fertilizers. Through soil testing and formula fertilization, we can find out the basic situation of the soil, meet the growth needs of potatoes according to the soil formula, and ensure the stable and high yield of potatoes. Secondly, coordinated fertilization throughout the year is the key. We should pay attention to the effective combination of agricultural machinery and agronomy, and realize efficient fertilization with the help of modern agricultural machinery.
At the same time, it is necessary to improve the fertilization method, that is, in dry land, combine deep application with machinery or change quick-acting fertilizer into quick-acting slow-release fertilizer; In potato drip irrigation and sprinkler irrigation, we should popularize the integrated technology of water and fertilizer, follow the principle of small amount and multiple times, and select new fertilizers with high efficiency and high concentration, such as liquid fertilizer, to improve the utilization efficiency of fertilizers.
To sum up, we should not only do a good job in technology, but also help farmers calculate their economic accounts. Through a series of integrated fertilization management measures, the overall investment is reduced, the planting benefit of farmers is not reduced, and even the income of farmers is increased.
