1、物质生产:作物群体的物质生产,决定于叶面积与太阳光能的利用效率,而光能利用效率受光合成能力和受光姿态所左右。从而,对栽培密度与品种的问题,如果从物质生产的观点出发,则为栽培密度对于叶面积、光合成能力、受光姿态的影响,以及品种间的差异。花生小叶的大小、厚度、单株总叶数和叶面积,两大品种群间有着明显的不同,据此,直立性品种与匍匐性、半立性品种比较,小叶虽薄,但长度和宽度大,小叶面积约有后两者的两倍。但单株总叶数却不及匍匐性和半立性品种,单株总叶
1, material production: material production of crop groups, depending on leaf area and solar energy utilization efficiency, and light utilization efficiency by the light synthesis ability and light attitude. Thus, the cultivation density and variety of problems, from the perspective of material production, then the planting density for the leaf area, photosynthetic capacity, the impact of light exposure, as well as the differences between varieties. The size and thickness of peanut leaflets, the total number of leaves per plant and leaf area were significantly different between the two populations. Therefore, compared with the creep and semi-sexual varieties, the erect leaves are thin, but the length and width Large, leaf area of about twice the latter two. However, the total number of leaves per plant is less than the creeping and semi-stereotypes, the total plant leaves
