一、试验目的科学的施肥技术是夺取水稻高产的重要环节。但是,当前在水稻施肥技术上存在着不同的观点,归纳起来主要有三种:一是竹笋形施肥法。这种施肥理论,强调分蘖肥的重要性,认为水稻有苗即有谷,因而、在肥水措施的运用上采取前期攻足,中、后期守的做法。二是“V”字形施肥方法,以潮汕老农施肥法为代表。认为水稻有效分蘖期和孕穗期是水稻一生中需肥最多的两个阶段,中期施肥则认为是有害无益的。因此,在肥水措施上采取前攻、中控、后促的做法,重
First, the purpose of the experiment Scientific fertilization technology is an important part of the high yield of rice. However, at present, there are different views on rice fertilization technology, and there are mainly three kinds of fertilization technologies: First, the bamboo shoot-shaped fertilization method. This fertilization theory, emphasizing the importance of tillering that rice has seedling valley, therefore, in the use of fertilizer measures to take pre-attack, in the late keep practice. Second, “V” -shaped fertilization methods to Chaoshan farmers fertilization method as the representative. It is considered that the effective tillering stage and booting stage of rice are the two stages of the most needed fertilizer in rice’s life, while the medium-term fertilization is regarded as harmful and unhelpful. Therefore, in the fertilizer measures to take pre-attack, control, post-promotion practices, heavy
