Abstract

Lacking nitrogenous fertilizer during wheat growth can influence the photosynthetic rate and content of chlorophyll and nitrogen in leaves. It can also lead to early senescence in the root vigor, which then functions at a low level. The more nitrogen the wheat lacks, the more significant influence is made on the wheat growth. This kind of decline in physiological function, which occurred after the florescence has a negative effect on the wheat milking and formation of seed, decreases the quantity of spikes, shortens the duration time of milking, and lowers the thousand grains weight and seed production of the wheat. Therefore, sufficient nitrogenous fertilizer is an essential way to prevent early senescence in the latter period of wheat growth.
