EFFECT OF SILICON NITROGEN SUPERPHOSPHATE GRANULATED FERTILIZER ON N AND P ASSIMILATION IN RICE |
| |
| Abstract: | 15N and 32P were used to investigate the effect of silicon nitrogen superphosphate granulated fertilizer on N and P assimilation of rice.The results showed that the silicon nitrogen superphosphate granulated fertilizer had positive effects on growth,increase of tiller and ear in rice.Application of the fertilizer at transplanting period increased 18.4% of rice yield.The total N and P accumulated in plant reached 11.45% and 12.10% respectively.The utilization rates of N and P with applying silicon nitrogen superphosphate granulated fertilizer at the stage of transplanting shoots were 7.7% and 3.4% higher respectively than those without applying the fertilizer. |
