农一师近几年来获得了水稻大面积丰收。在施肥方法上有了新的改进,采取了“前促、中控、后保”为主的追肥法。使水稻一生呈现了“前乌”(苗期至分蘖盛期);“中赤”(无效分蘖期至拔节初期);“后青”(拔节至成熟期)的规律性变化。这种施肥法的优点有四:(一)形成了“主蘖并重、穗粒并重”的丰产结构;(二)达到了“高产不倒青秆黄熟”的长势长相;(三)提高了肥效和经济效益;(四)有利于实现高产稳产。现将这种施肥技术简述如下:一、磷氮配合深施法:亩产千斤水稻,一般亩施过磷酸钙35公斤或三料磷肥或磷酸 In recent years, a division of farmers received a large area of ​​rice harvest. In the fertilization method has been a new improvement, adopted the “pre-promotion, control, after Paul” mainly based on fertilizer method. The results showed that rice had “Qianwu” (seedling to tillering stage), “Zhongchu” (inefficient tillering stage to early jointing stage), and “regular green” (from jointing stage to maturity stage). The advantages of this fertilization method are as follows: (1) A high-yield structure with “main tiller being equal and ear grain equal” is formed; (2) The growing status of "high- And economic benefits; (four) is conducive to achieving high and stable yield. Now this kind of fertilizer technology is briefly described as follows: First, the phosphorus and nitrogen with deep application method: per kilogram of rice, general Mushu over 35 kg of calcium phosphate or three fertilizer or phosphate
