新疆玉米生产农业气候资源及生产潜力估算

[目的]揭示新疆玉米生产农业气候资源及生产潜力,为新疆玉米生产提高产量提供有效途径.[方法]收集新疆12个具有代表点的玉米生育期光合有效辐射、各月平均温度和降水量等一些气候资料.[结果]新疆绿洲地区光温生产潜力冬季为0,夏季作物的光温生产潜力最大.南疆和东疆地区,包括吐一哈盆地和塔里木盆地周边等地区,为全区作物光温生产潜力的高值区,但玉米开花授粉时期温度过高,影响玉米授粉和灌浆.石河子和博乐等地其实际值比光温生产潜力估算值高.阿勒泰为作物光温生产潜力的低值区.[结论]新疆发展玉米种植具有很大的生产潜力,尤其是在南疆等地,种植复播玉米或套种玉米,充分利用后期光温充足的特点,为新疆发展玉米生产提高产量提出有效途径.

Agricultural Climatic Resources of Xinjiang Maize Production and Its Production Potential Estimation

[Objective]The purpose of this project was to reveal the Xinjiang maize production and agroclimatic resources and production potential to provide an effective way for the development of maize production in Xinjiang to increase its production.[Method]Xinjiang 12 representative points maize growing photo synthetically active radiation,the average monthly temperature and precipitation climate data were collected. [Result]Xinjiang oasis region of light,temperature and production potential in winter are zero,but the summer crop production potential of light and temperature is huge.In Southern and Eastern Xinjiang region, including spit - and Tarim basins and their surrounding regions,the high production potential value of light and temperature exists but for the maize pollination period,the temperature is too high,affecting maize pollination and grain filling.The production potential of light and temperature estimates in Shihezi and Bole has actually high value.Altay is the low value area of the production potential of light and temperature. [Conclusion]Xinjiang has great production potential in the development of maize planting,especially in Southern Xinjiang and other places,which can be regarded as effective proposal to increase maize production in Xinjiang.
