玉米的产量90%以上是靠光合作用积累起来的.但目前各种作物对光能的利用率是很低的.即是高产玉米全生育期对光能的利用率也只有1-2%.所以研究玉米合理群体结构,提高光能利用率以提高产量,是很值得重视的一个方面.本文根据试验资料,对高产玉米合理群体结构的生理基础,作初步分析.一、叶面积与产量的关系.叶子是光合作用的主要器官,在一定密度范围内,叶面积愈大,产量愈高.但当叶
More than 90% of the yield of corn is accumulated by photosynthesis, but at present, the utilization rate of light energy of various crops is very low, that is, only 1-2% of the utilization of light energy during the whole growth period of high-yield corn. Therefore, it is very important to study the reasonable structure of maize population and increase the utilization of light energy to increase the yield.This paper based on the experimental data, the physiological basis of reasonable population structure of high-yielding maize for preliminary analysis.First, the leaf area and yield The relationship between the leaves of the main photosynthesis organs in a certain density range, the larger the leaf area, the higher the yield, but when the leaves
