1983年建立早酥、锦丰梨密植栽培试验园36.37亩,平均每亩栽植40株。栽后第2年成花,第3年结果,第5年丰产。全园平均亩产5年生为1170.9kg,6年生为1638.6kg。其中亩栽74株早酥梨,5年生亩产2141.6kg,6年生达2696.1kg。5年生时全部收回投资并有盈余,6年内全园纯收益达55856.70元,平均每亩纯收益1513.4元。研究表明,梨幼树早期产量与干周及枝量间呈显著的复相关?迅速增加梨幼树早期枝量及干周,是早结果、早丰产的基础。同时总结出早结果、早丰产的主要农业技术措施,供生产上参考应用。
In 1983 to establish as early as crisp, Kam Feng pear close planting cultivation 36.37 acres of the park, an average of 40 acres planted. The second year after planting into flowers, the third year results, the first five years of high yield. The park average yield of 5-year-old 1170.9kg, 6-year-old was 1638.6kg. Among them, 74 were planted as early as morning pears, yielding 2141.6 kg per mu in 5 years and 2696.1 kg in 6-year-olds. 5-year-old all the time to recover the investment and a surplus, 6 years, the park net income of 55856.70 yuan, the average net profit of 1513.4 yuan per mu. The results showed that the early yield of pear saplings was significantly and repeatedly correlated with the dry weeks and the branches. The rapid increase of early shoots and dry weeks of saplings was the basis of early and early yield. At the same time summed up the early results, early bumper production of major agricultural technology measures for the production of reference applications.
