Shandong's "Eleventh Five-Year Plan" Agricultural Chemical Reduction of 30%

The reporter learned from the Department of Agriculture of Shandong Province that during the “Eleventh Five-Year Plan” period, the fertilization area in the province will reach more than 90%, and the amount of pesticides will be reduced by 30% from the present.
According to statistics, the province uses about 4.5 million tons of chemical fertilizer each year, and the actual utilization rate is only 40%. More than half of the fertilizer does not have the effect of increasing production and increasing efficiency. Even more shocking is the lower utilization rate of nitrogen fertilizer, only about 10%. According to relevant department statistics, the province wastes more than 800,000 tons of nitrogen fertilizer each year, worth up to several billion yuan.
In the use of pesticides, the relative backwardness of pesticide application technology greatly affects the efficacy of the drug. Most farmers still use knapsack sprayers, large volume sprays, and the actual utilization of pesticides is less than 30%. This method not only increases the cost of pesticide application, but also causes some pollution to agricultural products and the surrounding environment. What's more, there are still a large number of farmers still using high-toxicity, high-residue pesticides that the country has banned, and farmers using biochemical pesticides are minimal.
It is also known that the province’s mulching film covers an area of ​​about 26 million mu, and the amount of plastic film is more than 100,000 tons, and the remaining amount in the soil is as high as 50% or more. Experts pointed out that plastic film is a polymer compound with a natural degradation cycle of more than 250 years. When the residual plastic film per acre reaches 2 to 3 kg, corn can reduce production by 8% and wheat by 7%.
