| 摘 要： | 1986～1990年对9～10年生板栗低产园进行改造试验。试验后连续5 a平均单位面积产量比开始前3 a 平均增加410. 5%, 1990年平均产量达到1 339. 2 kghm- 2, 是开始前3 a 平均产量的9倍。低产园改造主要技术措施是: 高接换种, 缺株补植, 深翻改土, 施足基肥, 因树修剪, 以及套种、追肥和病虫害防治等。

| Abstract: | A test was made from 1986 to 1990 in a 9- to 10-year-old low-yielded Chinese chestnut stand. The post-test yield per unit area increased by 410. 5% on the average in sucessive 5 years, compared with that in 3 years before the test done. In 1990 the average yield reached 1 339.2 kg per hectare, which was 9 times as high as that in 3 years prior to the test. The main tecniques used in the improvement of the low-yielded stand included to pgraf ting for varietal change, replanting for increase of density, deep plowing for improvrmrnt of soil condition, applying sufficient basal manure, pruning, interplanting, doing top fertilizers and controlling both pests and diseases, all of which were, proved to be effective. |
