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,采用了“前促、中控、后保”为主的施肥法。使水稻一生呈现了“前乌”(苗期至分蘖盛期);“中赤”(无效分蘖至拔节初期);“后青”(拔节至成热)的规律变化。这种施肥法有如下优点:(一)形成了“主茎分蘖并重、穗粒并重”的丰产结构;(二)达到了“青秆黄熟、高产不倒”的长势长相;(三)提高了肥效和经济效益;(四)符合高产规律,有利实现高产稳产。现将“前促、中控、后保”施肥法简介如下:
In recent years, a division of farmers received a large area of rice harvest. In the fertilization method has been a new improvement, using the “pre-promotion, control, after Paul” based fertilization method. The results showed that rice had “Qianwu” (seedling to tillering stage), “Zhongchu” (ineffective tillering to early stage of jointing) and “post-green” (from jointing to becoming hot). This fertilization method has the following advantages: (1) A high yield structure with “equal weight of main stems and equal weight of grains and spikelets” has been formed; (2) The growth of “yellow stalk, high yield and no yield” has been reached; Fertilizer efficiency and economic benefits; (D) in line with the law of high yield, favorable high yield. Now “before the promotion, control, after Paul” fertilizer method is as follows:
