| Abstract: |
| In order to explore the best phosphorus fertilizer and application method used in cotton field in Xinjiang, the effects of different fertilizer types and application methods on uptake yield and soil balance in cotton fields in Xinjiang were studied. Six treatments were set up: no fertilizer (CK), triple superphosphate as base fertilizer (TSP-B), monoammonium phosphate as base fertilizer (MAP-B), urea phosphate as base fertilizer (UP-B), monoammonium phosphate applied with drip irrigation (MAP-D), urea phosphate applied with drip irrigation (UP-D). Soil and plant samples were collected in the bud stage, flowering boll stage and boll opening stage to determine the soil, plant accumulation and seed cotton yield. The results showed that, soil treated with MAP and UP was higher than that of TSP; and plant phosphorus uptake were higher under applied with drip irrigation than as bas fertilizers. In the boll opening period, the soil content under MAP-D and UP-D treatments were 46.34% and 105.12% higher than MAP-B and UP-B treatments. Compared with CK and TSP treatments, the yield of seed cotton under MAP and UP treatments was significantly higher, and drip treatment was slightly higher than base treatment. MAP-D treatment significantly increased yield by 41.38% and 37.82%compared to CK and TSP-B treatments. The fertilizer utilization rate and agronomic efficiency under MAP-D treatment were the highest, 25.44% and 19.59 kg·kg-1, respectively. The soil balance under MAP-D treatment was -39.99 kg·hm-2, which lowest among fertilization treatments. In summary, in Xinjiang cotton planting system, MAP and UP may be the better fertilizers compared with TSP in improving soil availability, seed cotton yield, fertilizer utilization rate and plant capability to use soil, and drip application slightly better than basal application. |
