1977年春按株行距0.67×1m和0.5×1m定植一年生晚三吉梨苗1.2亩,运用综合技术措施,实现定植后第2年结果(平均亩产77.67kg),第3年丰产(平均亩产4798.04kg),连续8年平均亩产超过5000kg,好果率均在99％以上。创出了7年生梨树最高亩产达到12913.59kg的记录。实现了11年生梨园1.2亩累计总产71249.5kg,年平均亩产5397.69kg。3年生梨园收回全部投资并有盈余,11年平均每亩年纯收入987.23元。总结出梨乔砧密植早结果、早丰产、持续高产的一套栽培技术措施,并提出双行水平树墙式丰产树体结构指标,可供梨乔砧密植栽培参考。
In the spring of 1977, 1.2 mu of annual mulberry seedlings were planted at a row spacing of 0.67 × 1m and 0.5 × 1m. Comprehensive techniques were used to achieve the results of the second year after planting (average yield 77.67kg), the third year (average yield 4798.04 kg), the average yield per mu for 8 years exceeded 5000kg, the good fruit rate was over 99%. Created a 7-year-old pears highest yield reached 12913.59kg record. Achieved 11-year-old pear orchard 1.2 mu cumulative total output of 71249.5kg, the average annual yield of 5397.69kg. 3-year-old pear orchard to recover all the investment and a surplus, 11 years, the average annual net income of 987.23 yuan per mu. Summed up the pear anvil close planting early results, early bumper crop, continuous high yield of a set of cultivation techniques, and put forward two-tier horizontal tree wall high yield tree structure index for Pear Joe anvil dense planting cultivation reference.
