Recently, the reporter learned from the Inner Mongolia Agriculture and Animal Husbandry Department that the use of chemical fertilizers in the whole district has increased in the past five years, and the increment has continued to decline. In 2017, while the total planting area continued to increase, the use of chemical fertilizers and pesticides in the whole district was effectively controlled.
'The four control actions of controlling fertilizer and increasing efficiency, controlling pesticides and reducing pollution, controlling water consumption and reducing the amount of controllable membranes are the main reasons for the decline in the growth of chemical fertilizer use,' said Wen Zhanping, the planting department of Inner Mongolia Agriculture and Animal Husbandry Department. At the beginning of the work of controlling the use of chemical fertilizers and pesticides, the Inner Mongolia Agriculture and Animal Husbandry Department focused on the prominent problems in the use of chemical fertilizers and pesticides, promoted the control of fertilizers and increased efficiency, controlled the harm reduction, controlled water consumption, controlled membranes, and improved utilization. , reduce the amount of use, and gradually achieve negative growth on the basis of controlling the increase.
'Structural adjustment, enhanced ground fertility, precise fertilization' are the three major tools for achieving 'negative growth' of chemical fertilizer application in Inner Mongolia. In terms of structural adjustment, the Inner Mongolia Agriculture and Animal Husbandry Department has adjusted to reduce corn that requires large amounts of fertilizer, and to expand soybean cultivation with small fertilizer requirements. At the same time, through the promotion of straw returning to more than 22 million mu, the farmland rotation system pilots 6 million mu, and the application of organic fertilizer 40 million mu, an increase of about 3 million mu. Compared with precision fertilization, the department promotes soil testing and formula fertilization technology area of 9000. Ten thousand mu, an increase of 3 million mu year-on-year, of which 42 million mu of formula fertilizer is used, an increase of 2 million mu compared with the same period of last year. According to statistics, in Inner Mongolia in 2017, the fertilization amount of chemical fertilizer per mu in the whole district dropped from 20.2kg in 2015 to 2017. 19.2kg, reduced by 1.0kg, a decrease of 5.0%.
It is reported that in the past five years, the Inner Mongolia Agriculture and Animal Husbandry Department has also promoted the negative growth of pesticide use through three channels: unified prevention and control, green prevention and control, and scientific drug use, which has reduced the fluctuation of pesticide use in the whole district. In the past five years, the district has implemented specialized defense. It has a total area of 31 million mu, a green control area of 27 million mu, and 130 green prevention and control demonstration zones. The core demonstration area is 1.8 million mu. In the past five years, the use of pesticides in the whole region has fluctuated and declined. In 2012, the total consumption was 14,800. Tons, reached the peak. In 2017, the use of pesticides was 12,800 tons, which was 9.8% lower than that of 2015. The average usage per mu decreased from 125g to 107g in 2017, down 18g, a decrease of 14.4%.
