云南省直干桉自50年代初从澳大利亚引种以来,发展很快。但是,过去多是零星分散种植,形不成商品。能否在低山丘陵地带大面积发展,其经济效益如何?一直是人们关心的问题。本文以《直干桉丰产栽培试验示范》科研成果为例,采用新增纯收益法、时间因素分析法、推广效果法进行经济效益测算与分析。通过测算,直干桉丰产栽培试验示范林每亩产值402.06元,比桉树一般林每亩产值多增175.66元。投入1元的科研费用,可获得515元。从1989年开始至1995年预计可收入3057万元。因此,可以肯定直干桉丰产林可以在低山丘陵地带大面积发展种植,并能取得显著的经济效益。
Directly from Yunnan Province, Eucalyptus since the early 50s introduced from Australia, the rapid development. However, in the past, scattered planting was mostly scattered and could not form a commodity. Whether it can be developed in a large area in the hilly areas and what is the economic benefit? It has always been a concern of people. In this paper, “direct and eucalyptus high yield cultivation experiment demonstration” scientific research achievements as an example, the use of new net income method, time factor analysis, promotion effect method to measure and analyze economic benefits. Through the calculation, the yield per mu of demonstration forest of high yield cultivation test of straight eucalyptus is 402.06 yuan, which is 175.66 yuan more than that of general forest of eucalyptus. Into 1 yuan of scientific research costs, get 515 yuan. From 1989 to 1995 estimated income of 30.57 million yuan. Therefore, it can be affirmed that the planting of straight-eucalyptus high yielding forests in large areas in hilly areas can achieve significant economic benefits.
