针对水稻生产中化肥的施用过量、利用率不高的现象，本文应用具有改善根际生物多样性功能的生物质小分子有机碳肥乌金绿，在不减少和减少肥料施用量两种情况下探讨其对水稻减肥增效的作用。结果表明，不减肥施用乌金绿和减肥施用乌金绿，均能提高水稻根系活力和叶绿素含量，增加有效穗数；乌金绿不减肥处理比常规用肥处理增产7.8%，乌金绿减肥处理与常规用肥处理产量相当，可避免化学肥料的浪费和减缓农业面源污染。

In view of the phenomenon of excessive fertilizer application with low efficacy in rice production, we conducted a trial of appling rice with Strongreen, which is a biomass micromolecule organic carbon fertilizer and can improving rhizosphere biodiversity, in reducing chemical fertilizer amounts and increasing fertilizers efficiency. The results showed that applying Strongreen and no reduced conventional fertilizer can increase rice yield by 7.8%, and applying Strongreen and reduced conventional fertilizer can obtain equivalent rice yield compared with the conventional fertilization, but it can avoid the waste of chemical fertilizer and slow down the agricultural nonpoint source pollution. Applying Strongreen in both cases can improve rice root activity and increase chlorophyll content and effective panicles.
