Limited studies have been conducted on the ecological impacts of transgenic insect-resistant cotton, especially for transgenic double genes （Bt＋CpTI） cotton, in this region. In this study, the potential effects of transgenic Bt＋CpTI cotton on the seasonal abundance of non-target pests and predators were assessed from 2009 to 2011 in Korla, Xinjiang. The results showed that species composition and seasonal abundance of 5 groups of pests and 5 groups of predators were not significantly different between transgenic Bt＋CpTI cotton and non-transgenic cotton every year. It suggests that transgenic Bt＋CpTI cotton per se does not affect the population dynamics of non-target pests and predators on this crop in Xinjiang.展开更多

Aiming for several main grain and economic crops of Xinjiang(cotton, corn and wheat), an intelligence decision support system for diagnosis and management of grain and cotton crop pests in Xinjiang was designed and developed, which was based on android platform and windows system architecture. APP application program of smart phones was used as an implementation form. The intelligence decision support system will help plant protection personnel and farmers to solve local pest recognition and prevention control problem at the grassroots level in Xinjiang remote regions.展开更多

However, the oases, dotted in the gobi deserts, are distributed at the foot of the enclosed mountains and a steppe in the centre of the Turpan Basin, and thus has a rathe vulnerable eco-environment. Since the 1980s, the cotton-growing industry has developed very quickly. The area of cotton-growing belt has increased from 181,000 hectares in 1980 to 866,600 hectares in 1997, which accounted for 34.7% of the total cultivated area in Xinjiang. The cotton output has correspondingly increased from 79,200 tons to 1.05 million tons and per hectare output has also increased from 438 kg to 1211 kg[1]. In recent decades, changes have taken place in agricultural products, such as the ratio of cotton and grain, total output and per hectare output with the expansion of cotton-growing belt. Before 1982, per hectare cotton output remained below 450 kg. Since 1982, thanks to the adoption of plastic film technique and such a planation mode as 'short, dense and early', namely, to select short-stalked, close planting and early maturing varieties, the per hectare cotton output has undergone a steady increase. After 1984, per hectare output reached more than 900 kg, and since 1995 it has reached 1435 kg per hectare, 9 folds more than that in the 1950s[1,2]. However the harmful organisms have accompanied the repaid expansion of the cotton-growing belt and the degree of deterioration has also kept increasing. Harmful organisms present a bottleneck for the further development of cotton production. To effectively control and protect against harmful organisms is the key to guaranteeing the steady development of Xinjiang cotton industry.展开更多

The main results were as follows: The contents of N, P2O5, K2O in cotton leaves, stems, squares and bolls decreased obviously with the time over the whole growth duration and the falling extent was greater in high-yield cotton than in CK. Contents of N in leaves, squares and bolls, in particular in the leaves of fruit-bearing shoot was higher in high-yield cotton than in CK. Contents of P2O5 in squares and bolls and that of K2O in stems were higher in high-yield cotton than in CK during the whole growing period. The accumulations of N, P2O5 and K2O in the cotton plants could be described with a logistic curve equation. There was the fastest nutrient uptake at about 90 d for N, 92 d for P2O5 and 85 d for K2O after emergence, respectively. Total nutrient accumulation of N, P2O5 and K2O was 385.8, 244. 7 and 340.3 kg ha-1, respectively. Approximately 12. 5 kg N, 8. 0 kg P2O5 and 11.1 kg K2O were needed for producing 100 kg lint with the leaves and stems under the super high yield condition of 3 000 kg ha-1 in Xinjiang.展开更多
