| Abstract: | The experiment was in the situation of the wheat nitrogenous fertilizer sufficient, the bottom phosphorus was insufficient, and the jointing initial period performance seriously lacks the phosphorus to carry on. The results indicated that pursuesing phosphate feailizer could promote the wheat growth, increase root system quantity, enhance the wheat ear ratio, increase yield re- markably. There were instruction significance to recovery phosphorus lacking to wheat on vegetal period, lacks phosphorus recovery to the wheat vegetal period to have the instruction significance. |
