| 摘 要： | 同等施肥量下,不同的施肥模式或将导致不同的施肥效应,形成不同的产量水平。本项研究针对水稻的基肥、蘖肥、穗肥、粒肥等环节,设置了四种氮磷钾的施用方案,相对应的产量构成因素--穗数/穴、成粒/穗、千粒重＂各有千秋、此消彼长＂。试验结果显示,处理2的施肥模式为最佳,获得了最高的产量。

| Abstract: | The different effect will be presentunder different fertilization of same fertilizer rate and therefore form different yield. The tests set four levels of N P K to study the base fertilizer, tiller fertilizer, panicle fertilizer and grain fertilizer, then the panicles per hill,grains per panicle and 1000-grain weight have their advantages. The results indicated that treatment 2 can receive better yield. |
