基　　金：云南省"九.五"重点攻关课题"滇东南岩溶山区生态经济林优良树种选择及营造技术试验示范"的研究内容之一。

摘　　要：在滇东南岩溶山区进行了早实核桃、美国山核桃、日本甜柿和奈李的引种和林农混作试验。结果表明:早实核桃、美国山核桃和奈李在引种区生长初期表现良好;奈李和早实核桃还具有早实的特性,4年生结实株率达100%,每公顷产量分别为4 673.8?和497?,每公顷产值为12 151.9元和2 982元,宜推广种植。若与花生、大白豆和辣椒进行林农混作,将会取得较高的经济效益和良好的生态效益。而日本甜柿由于受试区小气候(风和干旱)的影响和金龟子的危害,在试区内生长表现不良,但在该区水湿条件较好的地区和农家庭院还是可以种植的。An experiment was conducted to introduce J.sigillata×J.regia, Carga illinoensis, Disopyros kaki and Prunus salicina Lindl.var.Cordatn Y. He et J.Y.Zhang into Karst mountain area of southeast Yunnan and make mixed cropping of the four species and three crop species, Arachis hypogaea Linn, Phaseolus lunatus L.and Capsicum frutescens L., in the area. Results indicated that J.sigillata×J.regia,Carga illinoensis, Disopyros kaki and Prunus salicina Lindl.var.Cordatn Y.He et J.Y.Zhang showed fine performance in the early days of growth in the area; Prunus salicina Lindl.var.Cordatn Y.He et J.Y.Zhang and J.sigillata×J.regia have early maturing characteristic, and the percentages of number of four-year old fruiting trees of the two species both reached 100%, and the yield in each hectare of Prunus salicina Lindl.var.Cordatn Y.He et J.Y.Zhang and that of J.sigillata×J.regia are 4 673.8 kg and 497 kg respectively, and the output value of Prunus salicina Lindl.var. Cordatn Y. He et J.Y.Zhang and that of J.sigillata×J.regia are 12 151.9 yuan and 2 982 yuan respectively, and the two species are both fit to popularize and plant; fairly much economic benefit and rather great ecological benefit will be get if mixed cropping of the four species and the three crop species is made. Disopyros kaki showed a poor performance in the test region due to the negative effect of microclimate, i.e. wind and drought, in the test region and the damage caused by Cyphochilus farinosus, While this tree species might be planted in some farm courtyards and some other places where the humidity condition is fairly good in the area.
