库车干旱灌区农作物生产潜力分析及开发利用

Analysis of crop productive potentiality and developing ways in arid irrigation area in kuche County

对库车干旱灌区主要农作物的生产潜力分析表明 ,光合产量是实际产量的 5倍～ 8倍 ,灌溉产量是实际产量的 3倍～ 5倍 ,限制生产潜力发挥的主要因素是干旱少雨和地力低下 ,在保证灌溉的前提下 ,改良土壤和提高管理水平等农业综合技术 ,可使目前农作物产量提高 2倍～ 4.6倍。

This paper analyzed the crop productive potentiality of arid irrigation area in Kuch County. The result shows that the upper limitations of theoretical yield are 5~8 times as high as actual yield, and crop irrigation yields are 3~5 times as high as actual yield. The major constraints affecting the development of productive potentiality are less rainfall, drought and poor soil fertility. The improvement of soil and the comprehensive development of other agro technologies can raise crop yields by 3~4.6 times.
