| Abstract: |
| A field experiment was carried out to study the effect of phosphorus rates〔0(P0), 75(P1), 150(P2) and 225(P3) kg/hm2〕 on nitrogen, phosphorus and potassium uptake, utilization and yield of hybrid cotton with drip irrigation under membrane, so as to find out the reasonable phosphorus rates in this area. The results showed that: phosphorus rates could significantly increase biological yield, economic yield and total nitrogen, phosphorus and potassium uptake of hybrid cotton in maturity; The mutative trends of output of unginned cotton, nitrogen, phosphorus and potassium uptake, utilization ratio were P2>P3>P1>P0 under using different phosphorus fertilizer; Under our experiment condition, the phosphorus rates of hybrid cotton should be controlled at about 150 kg/hm2. |
