人们栽培作物、种植果树和蔬菜,实质上都是利用植物的光合作用制造有机物来形成产量的过程.农业上的施肥、灌水以及一系列栽培措施,也主要围绕改善光合条件,进而提高产量.因此,要对作物进行科学管理,必须了解光合作用与作物产量的关系.一、构成作物产量的因素 People cultivate crops, grow fruit trees and vegetables, are essentially the process of using photosynthesis of plants to create organic matter to form the yield of agricultural fertilization, irrigation and a series of cultivation measures, mainly around improving photosynthetic conditions, thereby increasing production. , The scientific management of crops, we must understand the relationship between photosynthesis and crop yield.
