摘要

Direct sowing on moistened paddy (DSMP) system enables to improve the ratio of seeding emergence and rice growth but poor lodging resistance. The object of the work is to establish a new way of evaluating the lodging resistance. Using a newdesigned instrumentation drawing out a rice stub with roots, lodging resistance of rice was measured for three varieties and three levels of crop density in a few weeks after heading. Shapes and amount of soil clod attached with roots were correlated with root density, and also they had a relationship to the properties of drawing resistance of stub. Recommendation was to reduce the seeding density or to enhance the rice tiller for increase in anti-lodging ability.
