中稻高产栽培最佳施肥量、施肥技术的研究
Study of Optimum Fertilizing Amount and Fertilization Technology of High-yield Cultivation of Middle-season Rice
摘要
Abstract
[Objective] The research aimed to provide the basis for the fertilizing method of high-yield cultivation of middle-season rice.[Method] Trials of different fertilizing method,different level of nitrogenous fertilizer and different level of potash fertilizer were carried out.According to the nutrient preserving capability of the soil,law of fertilizer requirement and fertilizer response,optimum fertilizing amount and ratio of N,P2O5 and K2O and the corresponding fertilization technology were given.[Result] Based on the experimental results,the optimum fertilizing method and optimum fertilizing amount were obtained with variance analysis.[Conclusion] The optimum fertilizing method was stabilizing before and attack the middle method,whose ratio of basic fertilizer,tiller fertilizer,fertilization for head sprouting and granula fertilizer was 4∶ 3∶ 3∶ 0.The optimum fertilizing amount of N,P2O5 and K2Owas 180,75 and 120 kg/hm2,respectively.关键词
