| Abstract: |
| Through the field plot experiment, the effects of two kinds of acid drip irrigation fertilizer on the growth, physiological function and yield of film-free cotton were studied. The results showed that the yield and it’s components of F1 fertilizer treatment ["Lvduoli" brand acid water-soluble fertilizer: urea 690kg/hm2, high phosphorus fertilizer (16-35-8+TE) 510kg/hm2, high potassium fertilizer (8-20-25+TE) 225kg/hm2] were significantly improved compared with F2 fertilizer treatment ["Feidigai brand acid water-soluble fertilizer: urea 725.5kg/hm2, feidigai (10-38-10) 382.5kg/hm2, and agricultural potassium sulfate (0-52-0) 240kg/hm2]. The yield of Zhong 19 was up to 5 360.74kg/hm2, which was 16.35% higher than F2 fertilizer treatment. The average yield of F1 treatment was 5 063.42kg/hm2, increased by 9.52% compared with F2 treatment, and the efficiency increased by 3 250.43 yuan/hm2. Conclusion: F1 fertilizer has a certain effect of increasing yield and efficiency, which is worthy of popularization and application in film-free cotton area in Southern Xinjiang. |
