摘要
１９９２～１９９５年对五莲县松柏乡王家口子村８ｈｍ２密植苹果园的间作物，进行了“五作四收”立体种植研究。结果表明，试验园苹果树定植的当年即可收回果园的全部投资，并且每公顷盈利２７０６８．８元。试验园２ａ平均一级果率９６．８％，平均单果重２３６．８ｇ，果实着色指数７３．８％，可溶性固形物含量７８．７％。试验园４ａ平均每公顷纯收入２７４１７．３５元，是４ａ平均每年每公顷投资（８８１８．５元）的３．１１倍；比对照园平均每公顷纯收入高１８３７６．５５元，是对照园投资（６３６７元）的４．３１倍。其产投比比对照园高１．７倍，效益显著。
The stereoplanting with intercrop filler in close planting apple orchard that covered an area of 8 hm2 was studied in Songbai township,Wangjiakou village of Wulian county from 1992 to 1995.The result showed that the total investment of the apple orchard could be taken back in the first year after the apple trees were planted and make a profit of 270688 yuan/hm2.The average first class fruit rate of 968%,the average single kernel weight of 2368g,the coloring index of 738% and the content of soluble solid matter of 787% were achieved in the two year old orchard.There was an average pure income of 274135 yuan/hm2·year in the four year old orchard,which was 311 times as much as the average investment for the orchard in four years(88185 year/hm2·year) ,183755 yuan/hm2higher than the pure income and 431 times as much as the investment in the contract apple orchard.The rate between invest and income was 17 times and the economical benefit was remarkable.
