摘要
不同氮、磷、钾肥施用比例对弱筋小麦苗期植株性状的影响结果表明:适量施钾(N∶P2O5∶K2O为1∶0.6∶0.6)能促进小麦苗期根系和地上部的生长,小麦根干重和地上部干物质积累量增加、叶面积增大和次生根数增多。但钾肥施用比例过高反而不利于苗期植株地上部和根系的生长。
In this article, the effects of potassium fertilizer application on the seedlings characteristics of weak - gluten wheat varieties Ningmai 13 and Yangmai 15 were studied. The results showed that suitable potassium application （N： P2O5：K2O = 1：0.6： 0.6） could promote the growth of root system and overground part of wheat seedlings, increase the root dry weight, accumulation of overground dry matter, leaf area and secondary root number of wheat. But too high proportion of potassium application was not good for the growth of overground part and root system at wheat seedling stage. The suitable N： P2O5： K2O was 1： 0.6： 0.6.
