Deng Zhenyong,Wang Heling,Li Guochang,Xin Jiwu,Zhang Yufei,Xu Jinfang. Study on the Cause of Formation and Countermeasure Effect of Climate Warming on Cotton Produce in Hexi Corridor[J]. Advances in Earth Science, 2008, 23(2): 160-166.

This paper opened out brass tacks that cotton produce occurring importance changes, growth duration extended 20d, frost bloom decrease 30%, in order region heighten about 100m,acreage enlarge 7 times, lint percent improve two percent, climate yield increase 54.3% in Hexi corridor. Prove up the reason of the favorableness effect of modern times climate warming on cotton is ≥10 ℃,accumulate temperature hoist 131 ℃, temperature increase 30 ℃ during split bell to stop growth, the lowest temperature increase 0.9 ℃, temperature increased step on the juice in spring and drop tardiness in autumn, compensated the heat resource in growth period consequently, climate zoology adaptability in order. Forecast ≥10 ℃ accumulate temperature increase 100~300 ℃ by any possibility within 10~15 years in the future. In order growth region heighten about 100m, make suggestions steadily extend planting area 20%~30%. Moreover bring forward take be on speaking terms agriculture manufacture technology according to different planting region.
