Abstract
Farmers blind and excessive use fertilizer in sprinkler irrigation circle of potato growing areas, only pay attention to use ignoring the protection, which causing the soil physical and chemical properties worsening year by year and making production efficiency lower. Organic fertilizer has an irreplaceable role on soil improvement, soil fertility. Through policy guidance, publicity and training, and materialized in the form of subsidies to encourage farmers to collecting , composting and increasing organic fertilizer to reduce the dosage of chemical fertilizer, change the concept of reuse to ground. We should make full use of organic fertilizer under the premise of ensuring crops benefit, which is the rich resources in Xilingol League, through optimizing fertilization structure, reduce the unreasonable investment, improve the quality of potato to achieve a fertilizer efficiency, and combination of organic-inorganic sustainable development road to reach fertilizer zero growth targets.关键词
