为了探讨香梨、砀山梨乔砧矮化密植早期丰产的可行性,我们于1982年春在库尔勒市建立试验园1.26亩,定植香梨、砀山梨嫁接苗376株,株行距1.5×1.5米.建园第二年即见果,第三年平均亩产433.8公斤,第四年平均亩产1562.3公斤,第五年平均亩产3261.0公斤;到第六年,平均亩产3738.7公斤,梨果品质优良,特级、一级优质商品果占85%,亩产值4039.9元,纯利为3272.9元,开创了库尔勒香梨早结果、早丰产、早收益的先例.现将我们采取的主要技术介绍如下.
In order to investigate the feasibility of fragrant pear and Dangsanliashen an dwarfing dense planting in the early stage of high yield, we established 1.26mu experimental garden in Korla in spring of 1982, planted fragrant pear and 376 grafted seedlings of Dangsanliarum with a spacing of 1.5 × 1.5m. In the second year, the park witnessed fruit. The average yield per mu in the third year was 433.8 kilograms, the average yield per mu in the fourth year was 1562.3 kilograms, and the average yield per mu in the fifth year was 3261.0 kilograms. By the sixth year, the average yield per mu was 3738.7 kilograms, , Special grade, a grade of high-quality goods accounted for 85%, 4039.9 yuan per mu, net profit of 3272.9 yuan, creating a Korla fragrant pear early results, early yield, early yield precedent now we introduce the main techniques are as follows.
