Effect Analysis of Root Growth Promoting Agent on Continuous
Cropping and Alternate Cropping Soybean
摘要
Abstract
Study on Root Growth Promoting Agent was conducted under field plot experiment and large area demonstration experiment. The results showed that Root Growth Promoting Agent could promote shoot and root growth of continuous cropping and alternate cropping soybean plants significantly at seedling, flowering and podding stages. Plant height, root length, shoot fresh weight, root fresh weight and root nodule weight all increased compared with control. The effect on root growth was most significant, with a increase over 10%. The agent enhanced photosynthesis of soybean leaves, made accumulation of dry matters increased, so that the leaf aera of soybean increased compared with control. The effect of the agent was different in different rotation. The effect decreased in the order of two year continuous cropping, altrernate cropping, three years continuous cropping and normal cropping. The agent iucresed total number of soybean seeds significantly, which made the yield of continuous cropping and alternate cropping soybean increased over 10% compared with control.关键词
