| 摘 要： | 1997~1998年在试验区进行了林农间适应及作物种类选择试验，结果如下；适度的林木郁闭对作物生长有利，郁闭度为0.35时，其生物产量和经济产量均优于0.125；郁闭度为0.67以上，不宜进行间种。适宜于试区土地条件的冬春作物有满园花、油菜；夏季作物有西瓜、甘薯、凉茹、辣椒、大豆、花生、豌豆等，但从防侵蚀角度考虑，甘薯、凉茹等收获地下块根的作物不宜选用。

| Abstract: | The experiment of forest and agriculture inter1cropping model of interspecific suit and crops choose in test plot was conducted in 1997～1998.Results as follows:moderate degree forest tree closing were beneficial to crops growth,canopy density was 0.35,its living things(output) and economic output were excellent than 0.125,canopy density was over 0.67,intercropping was not fit.Suitable to test area land condition’s,winter and spring crops were Manyuanhua,rape;summer and autumn crops were watermelon,sweet potato,Liangru,peoper,soybean,peanut,pea and so on.But from the angel of anti-corrosion,crops with underground root tuber were not fit to plant. |
