锡林郭勒盟马铃薯有机肥合理利用与实现化肥零增长问题探讨

Discussion of reasonable use and implementation of organic fertilizer and chemical fertilizer zero growth in Xilingol League

喷灌圈马铃薯种植区存在盲目过量施肥现象,农民只注重用地,而忽略养地,造成种植区土壤理化性状逐年恶化,生产效益降低。有机肥对改良土壤、培肥地力具有不可替代的重要作用。通过政策引导、宣传培训及物化补贴的形式,鼓励农民积造和增施有机肥,减少化肥用量,改变重用地轻养地的观念。充分发挥锡林郭勒盟有机肥丰富的资源优势,在保证作物种植效益不减的前提下,通过优化施肥结构,减少不合理投入,提高马铃薯品质,实现控肥增效,走有机-无机相结合的可持续发展道路,实现化肥零增长目标[1]。

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.
