作物是农田生态系统中最基本的机能系统。它的种类组成、品种组合,群体结构以及种群演替(轮、间、套作等)等特点,决定着农田生态系统的基本特征,影响到土地利用是否合理,生长季节和光能利用是否充分,以及农产品的数量和品质等。间接地还影响到动物生产的规模、农牧结合的水平和人民的食品结构。作物布局也影响农业生态
Crops are the most basic functional system in farmland ecosystems. Its characteristics such as species composition, breed assemblage, colony structure and population succession (round, intercropping and intercropping) determine the basic characteristics of farmland ecosystem and affect whether land use is reasonable, growth season and light energy utilization are sufficient, As well as the quantity and quality of agricultural products. Indirectly also affect the scale of animal production, the level of integration of agriculture and animal husbandry and the people's food structure. Crop layout also affects agro-ecology
