黄土高原设施农业种植制度探析

对黄土高原日光温室黄瓜与其他作物建立的不同种植制度研究表明,冬春茬黄瓜收获后采用不同轮作体系可显著减少土壤微生物数量;休闲降低土壤细菌和真菌数量效果最佳,其次为种植豇豆或与其他豆科作物轮作。翻青玉米、翻青黑豆和种植豇豆处理黄瓜产量较高,其次为夏季休闲,而种植番茄和小白菜处理黄瓜产量较低。并提出黄瓜与翻青玉米、豇豆、翻青黑豆轮作是有效预防和克服土壤连作障碍的较佳种植制度。

The cropping system for facility agriculture on Loess Plateau

The cropping systems of(cucumber) and other different crops which were conducted in plastic greenhouse on(Loess) Plateau were studied.The results show that after cucumber harvest,there is(significant) effects of different cropping systems on soil(microbe,) the soil microbe is the(lowest) in follow,the second lower is(planting) cowpea or other legumina(crops.) The highest cucumber yield can be got after(planting) corn for green manure,black-bean for green (manure) or(planting) cowpea,then higher(cucumber) yield can be got after follow,the cucumber(yield) is the lowest after planting(tomato,) cabbage.It is efficient rotation system for overcoming continuous cropping obstacle to use rotation system of (cucumber) with corn for green manure,black-bean for green manure or planting cowpea.
