不同时期喷施多效唑对大豆农艺及生理性状的影响
Effects of PP333 Spraying at Different Stages on Soybean Agronomic and Physiological Characters
摘要
Abstract
The research taking ‘Jiyu88’ as material, aimed to study the effects of plant growth regulator PP333 spraying at V4,V7,V10 and V13 stage on the soybean agronomic characters and physiological traits. The results showed that PP333 spraying increased SPAD value and photosynthetic rate, decreased leaf area; significantly reduced plant height by adjusting intemode length. The effect of PP333 on soybean yield varied with application stage, spraying at V10 significantly increased seed yield by 9.9％; spraying at V4 and V7 had no significant difference compared to CK; while spraying at V13 significantly decreased seed yield, indicated that V10 was the best stage for spraying PP333.关键词
