配方施肥是我国施肥技术的一项重大改革.80年代以来,我省陆续在稻田上推广几种配方施肥法,例如养分丰缺指标法、氮磷钾比例法及氮调法等等,都取得了显著的经济效益.1986年冬,刘中柱兄弟提出了“土壤识别与优化施肥”技术(简称优化施肥法),由于此法简便实用,引起省内土肥工作者的极大兴趣,纷纷做了各种不同处理的对比试验,以验证优化施肥法与其他配方施肥的增产效果.现将几年来试验结果比较如下. Formulation fertilization is a major reform of fertilization technology in our country.From the 1980s, our province has promoted several formula fertilization methods on paddy fields one after another, such as the index of nutrient abundance and deficiency, the ratio of nitrogen, phosphorus and potassium and the method of nitrogen adjustment, etc. A significant economic benefits.In the winter of 1986, Liu Zhongzhu brothers put forward the “soil identification and optimization of fertilization” technology (referred to as the optimization of fertilization method), because this method is simple and practical, causing the great interest of soil fertility workers in the province, have done Different treatment comparison test to verify the optimized fertilization and other formula fertilization yield results now test results in recent years are as follows.
