作物的经济产量决定于光合面积、光合强度、光合时间、光合产物的消耗和分配.在这些因素中,光合面积与产量关系极为密切.大蒜在生长过程中相邻株间叶片交叉重叠现象是常有的,在密植情况下,这种现象相当严重,对光合面积以及光合产量造成很大影响.近年,我们通过对大蒜叶片分布规 The economic yield of crops depends on the photosynthetic area, photosynthetic intensity, photosynthetic time, photosynthetic product consumption and distribution of these factors, the photosynthetic area and yield are closely related to the garlic growth during the process of cross-overlap between adjacent plants is often Some, in the case of close planting, this phenomenon is quite serious, have a great impact on photosynthetic area and photosynthetic output.In recent years, we passed garlic leaf distribution rules
