摘要
本项研究是在对寒温带低山丘陵地区的果农复合经营的果园生态因子和农民经济收入进行深入调查的基础上．进行了果农复合生态系统因子动态变化分析、间作农作物种类比较分析和经济效益综合分析。结果表明：果农复合生态经营模式具有重要的生态学效益和经济收益．它能够有效地改善果园条件．降低空气温度．提高空气相对湿度．增加土壤有机质、全氮和全钾的会量．有利于果树和农作物的生长和土壤改良；果农复合生态经营可分为果树生长初期、果初期、结果盛期三个阶段；适于低山丘陵区果农复合的最佳模式是在果树行间间作瓜类、豆类和蔬菜类．可根据实际情况具体操作。
The dynamic analysis of ecological factor, the comparative analysis of companion crop types and thesynthetic analysis of economic benefit were made on the base of investigating the ecological factor andincome of farmer in the low hilly land. The study showed that the fruit-crops compound ecologicalmodel had the result of ecology and economy. and could improve the environmental condition oforchard. reduce the air temperature. raise the air relative humidity and increase the proportion of organicmatter. full-N and full-p in soil. These could benefit the growth of the fruit trees and crops and soilamendment. The fixed number of years of fruit-crops compound ecological model was divided into threestages: the initial stage of growth, the early days of bear fruit. the hey-day of bear fruit. The best fruit-crops compound ecological model suited to the low hilly land is that melon. beau and vegetables areintercropped according to the local objective reality.
