摘要
在田间栽培条件下研究了增产菌对甜菜的生理效应,研究表明:在不同生育期增产菌均能促进甜菜的根叶生长,并能减少叶片的气孔阻力,促进甜菜的光合作用,改善光合产物的分配以及提高甜菜的蒸腾速率和水分利用效率。
The physiological effects of yield increasing bacteria (YIB) in field cultured sugarbeet were studied, the results obtained are as follows:YIB could promote root and leaf growth of sugarbeet in different development stages, it also could reduce stomatal resistance and improve photosynthesis and transpiration rate, made the allocation of photosynthate better as well as increase water use effeciency.
