| 中文摘要: |
| 我国荔枝龙眼主产区果树树龄平均在10年以上，60%以上的果园存在不同程度的郁闭现象，亟待进行间伐改造。本研究通过对主产区农户问卷调研，分析农户间伐技术采用情况，评估间伐的技术经济效益，为郁闭荔枝果园间伐改造技术的推广提供参考依据。2011年7月至11月在广东、广西、海南对257户农户组织了问卷调研，其中117户采用了间伐技术，占45.5%。间伐后卖树的收益基本可以弥补砍树的成本支出，部分农户反映会略有盈余。大多数果园间伐后每亩收益比改造前明显增加。对间伐技术采用户和未采用户进行对比分析表明，户主年龄、受教育年限、家庭人口总数、果树树龄、种植面积、水果收入比重、亩均销售收入、人均管理种植面积等不同农户禀赋对农户是否采用间伐技术存在显著影响。 |

| Fruit tree tree age shares main our country Litchi chinensis longan producing area above 10 , there exists the closing phenomenon to varying degrees in 60% the above orchard , reforms urgently after carrying out intermediate cuttings. The peasant household questionnaire studying originally by main couple producing area is surveyed, the analytical peasant household intermediate cuttings technology adopt condition, basis appraising the intermediate cuttings technology economic effect , providing a reference in order closing Litchi chinensis orchard intermediate cuttings reforms the technology extension. Survey till the peasant household of family has organized a questionnaire in Guangdong , Guangxi , Hainan to 257 November in July , 2011, among them, 117 family have adopt the intermediate cuttings technology , have accounted for 45.5%. The avails selling a tree can make up the cost disbursement chopping a tree basically , that the part peasant household reports is able to have a bit having a surplus for behind intermediate cuttings. Great majority increase by behind orchard intermediate cuttings is more obviously than reforming front each mu avails. The technology adopt pair of intermediate cuttings the family indicates age , cultivated area , fruit income specific gravity , mu of equal income from sales of products , per capita administration cultivated area with not having adopt a family to carry out comparative analysis , head of a household age , population size , fruit tree the fixed number of years , the family are educated set up Deng Bu Tong the peasant household gift there exists notable effect in technology to if peasant household adopt intermediate cuttings. |
