Effect of Integration of Water, Fertilizer and Soil Amendment on Cotton Yield Improvement and Soil Salt Control
摘要
Abstract
[Objective] This project aims to study the effect of increasing the application of soil amend-ment on cotton yield and soil salt control in saline-alkali soil on the basis of drip irrigation and fertilization under the integrated film of field water and fertilizer.[Method]The experiment was carried out in Shawan County in 2017. There were five fertilization treatments in the experiment:control (no fertilization), conven-tional fertilizers, conventional fertilizers + soil amendment, special fertilizers and special fertilizers + soil a-mendment. Each treatment was repeated 3 times and set in a randomized block in the experimental plot. The determinant indicators were cotton yield, dry biomass, soil pH and soil conductivity.[Result]The convention-al fertilizers + soil amendment was the best. The average effective bolls were 6. 8 per plant. The average sin-gle boll weight was 5. 95 g, and the cotton yield was 6,640 kg/hm2 ,which was 17. 4％ higher than that by conventional fertilizers treatment. Soil amendment could reduce soil pH. Soil conductivity at 0 cm from the dripper was lower than that at 30 cm, indicating fertigation was effective for washing salt. [Conclusion]The addition of soil amendment can increase effective cotton bolls and promote boll weight, and can effectively in-crease cotton yield and reduce soil pH to improve soil environment.关键词
