水稻分蘖成穗与产量组成关系分析

Analysis of the Relations between Panicle Bearing Tillers and Yield Components of Rice

通过对水稻分蘖成穗与产量组成数量关系的分析表明：（1）提高成穗率即可提高产量及其组成因子；（2）群体穗数与产量多呈负相关，单株穗数与产量多呈正相关；（3）群体的苗、茎（蘖）、穗与成穗率多呈负相关，单株的茎（蘖）、穗与成穗率多呈正相关。

This expdriment in the analysis of the relations between panicle bearing tillers and yield components of rice showed:(1)Raising the Panicle bearing tillers rate increased the yield and component factors;(2)There was a negative correlation be-tween panicles number and yield and positive correlation between panicle number per plant dnd yield; (3)Ther was anegative correlation between the number of seedling,stem(tiller)per mu and oanicle bearing rillers tate;there was positive correlation be-tween Stem(tiller)number per plant and the panicle bearing tiller rate.
