针对我省荔枝生产上存在的稀植、结果晚、产量低、不稳产的关键技术问题，从１９８２年起，以怀枝品种为试材，进行矮化密植早果丰产综合技术研究。通过适度密植，促进幼龄树早生快长；培养适时健壮的秋梢结果母枝；控制冬梢，促进花芽分化；壮花保果及回缩修剪等综合技术，使怀枝早果丰产，栽植后第３年结果，第８年每公顷产量达１３３１１ｋｇ，明显超过传统栽培的成年结果树每公顷７５００ｋｇ的最高产量水平，并连续保持高产稳产。
Aiming at the key technical problems of thinning planting, late result, low yield and unstable yield of litchi production in our province, from 1982 onwards, we carry out the comprehensive technology research of shortening and planting early yield and high yielding with the varieties of Wakabayashi. Through moderation and close planting, young trees will be promoted to grow faster and faster in early life. Cultivation of sturdy branches of autumn shoots with proper robustness will result in the control of winter shoots and the promotion of flower bud differentiation. In the third year of the project, the yield per hectare in the eighth year reached 13,311kg, which clearly surpassed the highest output level of 7500kg per hectare of the mature adult tree and maintained a high and stable yield continuously.
