有机肥对小麦增产作用的研究

本文报导了在太湖流域的3个不同地点进行为期4年、重夏6次、184个处理的试验。结果表明,增施有机肥出叶速度快。植株生长量大。发蘖早,分蘖多,光合作用强,增加了物质积累,灌浆强度大,因穗多、粒多、粒重而增产。在使用225kg/ha纯氮的条件下,至少搭配25％～37.5％的有机氮,并做到两头促、中间补是小麦高产稳产的施肥技术。

A Study on the Function of Organic Fertilizer for Incresing the Yield of Wheat

This study is conducted on 3 different sites in the Taihu Lake valley for 4 years,6 repeats and 184 treatments.The results of the tests indicate that the increasing the organic fertilizer will result in faster growth of leaves,higher growth rate of the plant,earlier and more exuberant tillering,stronger photosynthesis.more accumaulation of matter and more intensive milking.So the amount of ears and grains of wheat will increase,the grains will be heavier and it is sure to reap a good harvest.
