一、概述大田株行布局对作物的光环境的变换起着决定性作用,而光环境中又有直射光和漫射光之分。谢尼可夫在评论植物光环境时指出:“……漫射光能较完全被植物利用,它对植物的光能利用亦较有利,漫射光中包括红、黄光约50-60%,而直射光中仅37%左右,因此,漫射光对植物的生态意义远比直射光有利。”人们研究作物栽培技术时,如何创造漫射光比 First, an overview The field layout of rows of plants on the crop’s light environment transformation plays a decisive role, while the light environment has direct light and diffuse light points. Commenting on the light environment of plants, Sennikov pointed out: “... stray light can be used more completely by plants and it is also advantageous for the utilization of the light energy of plants, including about 50-60% of red and yellow light in diffuse light, Direct light only about 37%, therefore, the ecological significance of diffuse light on plants far better than direct light. ”People study crop cultivation techniques, how to create a diffuse light ratio
