Abstract
The quantity and quality of the fertilizers affected the photosynthetic characteristic of the winter wheat. So, the rationality applied, reduced fertilizers not only can decline pollution for soil and ground water, but also save the cost. The quantity and quality of the fertilizers determine the relationship between the photosynthetic characteristics. Therefore, the different effects about the using of the Controlled Release Fertilizer (CRF) and the Conventional Complex Fertilizer (CCF) on photosynthetic characteristics in winter wheat were studied in the open field by pots experiment. The results showed that the SPAD value, photosynthetic rate and stomatal conductance of the treatments of the mixture of the CRF and equivalent CCF applied were higher than that of the treatments of CRF used alone and the control treatment, but the intercellular carbon dioxide concentration of both latter was higher than that of the former. So it can conclude that it was the best way to maintain higher photosynthetic rate in winter wheat by using the amount application and the way of application of fertilizer of T6.
