Abstract
In order to research the use ratio of controlled release fertilizer in winter wheat. So, the experiment about the effects of Controlled Release Fertilizer (CRF) and Conventional Complex Fertilizer (CCF) on the dry matter accumulation and the grain yield in winter wheat has studied with pots in the open field. The results indicated that the CRF improved the proportion of the number of effective tillers to the total number of tillers. And the mixture of the CRF and equivalent CCF have more improved the proportion of the dry root weight to the total dry matters of the after of wheat flowering stage than that of the CRF used alone (T1, T2, T3). The treatment T6 was more improved the accumulation of the dry matters of aerial part than others. And the weight gain of T6 after a thesis was higher than other treatments and the control treatment (CK). In the facts of grain number per spike, thousand grain weight and yield, the treatments of the mixture of the CRF and equivalent CCF (T4,T5,T6) were higher than that of the treatments of CRF used only (T1,T2,T3) and CK, in which the T6 was highest. So, we think that this treatment namely T6 was used fertilizers least and gained the highest yield of grain.
