河西走廊在耕作改制中推广的带状种植,简称带田,改变了以往的单一作物生产为多种作物配合的两季生产,使产量大幅度增加。为了弄清带田光能分配的特点,并为带型设计提供科学依据,从1975年至1978年我们在武威县羊下坝公社和清水公社进行了试验。试验研究结果如下: Hexi Corridor in the farming system to promote the strip planting, referred to as field, changing the previous single crop production for a variety of crops with two seasons of production, so that a substantial increase in output. In order to find out the characteristics of light distribution in the field and provide a scientific basis for the design of the belt type, from 1975 to 1978 we conducted experiments in Shexiaxia Commune and Shuicheng Commune in Wuwei County. The experimental results are as follows:
