摘要
本文针对阿拉尔垦区主要农作物的光合生产潜力、光温生产潜力、天然状态下光温水生产潜力、光温水土生产潜力及灌溉保证下的土壤生产潜力进行了计算和分析。结果表明,水分和肥力是限制该区生产潜力发挥的主要因素。在此基础上,对提高本地区农业资源生产潜力的主要措施进行了讨论。
The potential productivities of photosynthesis, the potential productivities of the light and temperature, the potential productivities of the light, temperature and water in the state of nature, the potential productivities of the light, temperature, water and soil in the state of nature, the potential productivities of soil regulated by irrigation of the main crops were analysed and calculated. The results showed that water and fertilizers were the major limitation factors. On the basis of calculation and analysis, this paper put forward the major measures which could improve agricultural resources potential productivities of the Alar irrigated area in South Xinjiang.
