所谓平衡施肥,就是根据不同的土壤肥力、气候和轮作制度,确定合理的氮、磷、钾及微量元素的适宜用量和比例,实施有机肥与无机肥相结合的施肥技术。其实质就是科学施肥,平衡供给作物营养,提高农作物产量和生产效益。 根据内邱县的土壤肥力、气候和轮作制度,结合近几年的工作实践,总结归纳了内邱县平衡施肥的几点做法:1 增施有机肥。通过抓好有机肥积造、秸秆还田以及发展绿肥和固氮作物等途径,增加土壤有机质含量,提高土壤肥力。为确保施肥效果,一般把有机肥作基肥底施,每亩施用量3立方米以上。以改善土壤理化性状,全面调节和供给作物养分。2＄施氮肥。合理施用氮肥,既能直接增加作物
The so-called balanced fertilization is based on different soil fertility, climate and crop rotation system, to determine the appropriate amount of nitrogen, phosphorus, potassium and trace elements and the proportion of the implementation of organic fertilizer and inorganic fertilizer combination of fertilization techniques. Its essence is scientific fertilization, balanced supply of crop nutrition, improve crop yield and production efficiency. According to the soil fertility, climate and rotation system of Neiqiu County, combined with the work practice in recent years, several practices of balanced fertilization in Neiqiu County are summarized: 1. Through the accumulation of organic fertilizer, straw returning and the development of green manure and nitrogen-fixing crops and other means to increase soil organic matter content and increase soil fertility. In order to ensure the fertilization effect, the general application of organic fertilizer as basal fertilizer, the application rate of 3 cubic meters per acre or more. To improve the physical and chemical properties of soil, fully regulate and supply crop nutrients. 2 $ Nitrogen fertilizer. Rational use of nitrogen fertilizer, both directly increase the crop
