幼龄胶园行间间种甘蔗的生态与经济效益分析

Ecological and economic benefit analysis of young rubber interplanting with sugarcane

通过幼龄胶园间种甘蔗对土壤肥力特性、胶树生长及经济收益的研究,分析间种甘蔗对胶园生态效益和经济效益的影响。结果发现,幼龄胶园间种甘蔗对土壤温、湿度影响不大,但降低了土壤p H值、有机质和土壤养分含量,其中速效钾含量降低幅度最大,从而对橡胶树增粗有一定的影响;从产出方面来看,间种甘蔗可净增加13 695元/hm2的经济收益,而不间种则需要支出除草费用1 275元/hm2。

Based on the interplanting with sugarcane in young rubber plantation,the soil fertility characteristics,the growth of rubber trees and the increased economic income were studied to analysis the ecological and economic benefits of rubber plantation interplanting with sugarcane. The results showed that,the soil temperature and moisture were little affected,but soil pH,soil organic matter content and soil nutrient content were all decreased,of which the available potassium reduced most. The soil fertility of rubber plantation decreased so the growth of rubber trees was effected to some extent. From the output point of view,13695 yuan / hm2 net increased economic benefit was obtained in young rubber plantation interplanting with sugarcane,but the control need to pay some weeding costs about 1275 yuan / hm^2.
