摘　　要：开展板栗低产园改造技术试验研究,采用高接换种配置授粉树、微肥"三喷"、间伐降密、结合树体管理、无公害化防治病虫害等综合技术措施,对8～10a生年生低产栗园实施改造,产量由改造前的1245.0kg/hm2和487.5kg/hm2提高到了5461.5kg/hm2和4637.3kg/hm2。增产4216.5kg/hm2和4149.8kg/hm2,增值2.4万元/hm2和2.3万元/hm2,增产率达338.7%和851.2%。The test study on improving technology in low-yield garden of Castanea mollissima Blume. was carried out. The technological measures of top grafting and pollination tree, thinning and low density, trees management, nuisance free and disease and insect pests control was adopt. The yield from 1 245 kg/hm^2 and 5 461.5 kg/hm^2 to 5 461.5 kg/hm^2 and 4 637.3 kg/hm^2. the increase production were 4 216.5 kg/hm^2 and 4 149.8 kg/hm^2,increased 24 thousand Yuan/hm^2 and 23 thousand Yuan/hm^2, The increase ratio was 338.7% and 851.2%.
