摘要: 对水稻植株七种营养元素分析水稻坐蔸的原因,一是P、K、Zn的不足和Mn过剩,二是各营养元素之间相互吸收与运输及拮抗作用,造成植株生长系统内养分不平衡。通过养分适量的调节,增产效果明显。

关键词: 水稻, 坐蔸, 营养元素, 平衡调节

Abstract: Seven nutritive elements of rice plant were analysied. The reason of root decline, on one hand, is the insufficient of N, P, Zn and surplus of Mn and on the other hand, was caused imbalance of nutrient on the plant growth sysitem, for every element could promote or keep from absorption and transplanting. It's obviously to promote the yield of rice by adjusting it's nutrition creactly.

Key words: RICE, ROOT DECLINE, NUTRINET ELEMENT, BALANCE ADJUSTMENT
