摘要
研究不同种植方式玉米田玉米害虫与产量、无敌与产量的关系。并得出：间作套种的玉米比纯玉米的玉米螟该害株率减少，天敌增多，系统产量提高；间套作方式中，玉米套红薯依次优于玉米间大豆、玉米间花生和纯玉米。
When intercropping,with corn being the main crop,corn pests are directly correlated tothe production of corn and the pests are inversely related to their natural enemies. The rate of corn mortality when intercropping is less than when intercropping is absent.When intercrop-ping there are more natural enemies of the corn pests and as a consequence the production ofcorn is higher than when the crops are grown apart.When comparing different intercroppingmethods,the combination of corn and sweet potato gives better results than that of corn andbeans,the combination of corn and beans gives better results than that of corn and peanuts andthe combination of corn and peanuts gives better results than single corn.
