Effects of Drought Stress on Cotton Output and Fiber Property of Different Cultivars

Abstract:

Under adverse soil situations and simulated extreme climatic conditions, use the orthogonal design method and study the effect of 3 cultivars (Xinong Kang NO.4, NO.5 and Zhong mian NO.41 on lint output and quality by conducting the coupling water saving farming practice. The results showed that K4 and K5 perform better in output than the control (Zhong mian NO.41) and appeared drought resistant to some extent. No irrigation or with few irrigation (water saving), the outputs of the plots of irrigation regions suffering from water stress are better than control (irrigating two-three times), average output is increased by 8.11%. Compared with control, the plots with optimal combination of water saving farming practices and drought resistance have higher lint outputs and various fibers, increased by 4.62%~13.76% and by 5-10% on average separately. These demonstrated that coupling of water saving farming practices and drought-resistant varieties had significant effects on cotton output and quality, it provides water-saving agriculture engineering theory basis for the arid and semi-arid area.
