Primary discussion on the effects of micro drip-irrigation high-efficient compound solid fertilizer applied to high-yielding cotton planting in Xinjiang.

【Objective】The main purpose of this study was to indentify the effects of micro drip-irrigation high-efficient compound solid fertilizer applied to high-yielding cotton planting in Xinjiang.【Method】The compative test was conducted among the four groups including:micro drip irrigation high-efficient compound solid fertilizer applied with water,the local common appication of fertilizer,micro drip irrigation high-efficient compound solid fertilizer and other drip-irrigation special fertilizer.【Result】The coefficient of cotton leaf area of treatment 1(Micro drip irrigation high-efficient compound solid fertilizer)were increased by 0.47,compared with the treatment 2(Common application of fertilizer),the number of leaf per plant were increased by 3.2 leaf/plant.Aboveground dry matter weight of cotton plant were increased by 8.74 g/plant.Subsurface matter were increased by 0.68 g/plant.The cost of mico drip-irrigation high-efficient compound solid fertilizer were reduced by 206.11 yuan per ha.compared with common application of fertilizer.Seed cotton were increased by 301.8 kg/hm2.The net income was increased by 1 023.9 yuan/hm2.The seed cotton from micro dripirrigation high-efficient compound solid fertilizer were 341.5 kg/hm2 more than that from other drip irrigation special fertilizer.The profit was increased by 1 115.78 yuan/hm2.【Conclusion】The test indicated that micro drip irrigation high-efficient compound solid fertilizer could help make cotton yield increase,which is worth being popularized in large area.
