摘　　要：去劣疏伐是提高种子园产量和品质的主要措施之一，而无性系再选择则 能科学地确定出疏伐对象。通过子代测定和对无性系开花结实及产种量的观测， 综合评定出优、中、劣无性系，从而制定出疏伐强度、疏伐时间等疏伐方案。同时，向其它油松基地推广评选出的油松优良无性系。Thinning is one of the main methods for improving genetic qualities and yields of seed in seed orchards. Trees to be thinned could be scientifically selected through clone re selecting. By means of progeny tests and observing of flowering and seed yield of clones in seed orchard the best, middle and the poorest clones could be selected, and the intensity, date and plan of thinning be determined.
