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。
Film mulching cultivation is a new form of production in protected areas. In recent years, more than 60 kinds of crops have been tested in various places in China, and large-scale popularization and utilization has been carried out. In this paper, the growth of Rehmannia glutinosa and Rehmannia glutinosa cultivated under plastic film mulching was measured. The changes of temperature, humidity and other factors were analyzed and compared, and the yield and quality of the two cultivated Rehmannia glutinosa after harvest were compared. Practice has proved that the application of film to rehmannia is feasible and can improve the yield and quality of rehmannia. The cost is low and simple.
