Abstract

The result of experiments and investigation showed that: When the soybeans were planted continuously and alternately, some abilitiy of their roots were depressed. They were growth, energy, ability to absorb nutrition and water, and the ability of resistance to diseases and insect pests. It can advance growth and buildup function of roots and increase output of soybeans to accommodate micro-ecological environment around roots. All of these shown that the change of root energy and the root ability to absorb nutrition and the ability reduce of resistance to diseases and insect pests was an important reason to reduce output of soybeans planted continuously and alternately. 
