【摘要】 地膜覆盖栽培是保护地生产的一种新的形式,近年来我国各地在60多种作物上进行了试验,并进行大面积推广利用。本文测定了地膜覆盖栽培地黄与露地栽培地黄之间的生长情况,分析比较了两者温度,湿度等一系列因子的变化情况,以及收获后两者在产量,质量上的比较。实践证明,地膜应用于地黄生产是切实可行的,能提高地黄产量和质量,成本低、简单易行。更多还原

【Abstract】 Recently, plastic film has been used in our country as soil mulch in more than sixty crops in their early growth.It is one. of the new ways inprotected cultivation and is still extending in use. Hueiching rehmannia (Rehmannia glutinosa Libosch f, hueichingensis (Chao et Schin.) Hsiao) was cultured under plastic film as soil mulch in our experiment. Several factors such as temperature, moisture were measured in the early growth stage.The rehmannia cultivated with plastic film was compared with that in the open air in their quality and yield.Result showed that plastic film used as soil mulch is a more available means in the rehmannia production, because of its low cost and easy operation更多还原
