| 摘 要： | 去劣硫伐是提高种子园产量的主要措施之一，而无性质再选择能科学地确定疏伐对象。通过子代测定和对无性系结实量观测，采用综合指数法综合评定出优、中、劣无性系，从而确定疏伐对象、疏代强度、疏伐时间等。对已进入盛果期的种子园可对结实母树进行整形修剪，增加结实量。施肥能促进种子园母树生长和开发结实，提高种子产量。 |

| Abstract: | 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 by clone re-selecting By means of progeny tests and observing of flowering and comprehensive index of 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 The pruning of maternal plant can improve its yield of entering high yield the seed orchard of Pinus tabulaeformis Fertilizing can promote maternal plant developing and flowering and seed yield in Chinese pine |
| Keywords: | Piuns tabulaeformis seed orchard technique of fructification |
