惠民县是理想的棉麦产区,但由于热量的限制,一年只能种一季棉花或一季小麦和一季玉米,不能实现正常的麦棉两熟。为了充分发挥黄河水利资源优势,挖掘光热资源潜力,于1982年进行了棉麦套种一膜两用试验,迄今已经4年了。实践证明,棉麦套种采用一膜两用后,不仅实现了麦棉两熟,而且经济效益高。据统计,1983～1985年,小
Huimin County is the ideal area for cotton and wheat production. However, due to the heat restriction, only one season of cotton, one season of wheat and one season of corn can be planted each year, and the normal double cropping of wheat and cotton can not be achieved. In order to give full play to the advantages of the Yellow River water conservancy resources, tap the potential of light and heat resources, cotton and wheat intercropping a membrane dual-purpose test in 1982, so far 4 years. Practice has proved that cotton-wheat intercropping with a membrane dual-use, not only to achieve a two-cotton wheat, but also high economic benefits. According to statistics, from 1983 to 1985, small
