沈阳地区玉米光热水生产潜力研究

Studies on the solar Light, Thermal and Watery Potential Productivity in Shenyang Region

在玉米光热生产潜力的基础上，进一步讨论沈阳地区水分对玉米生产潜力发挥的限制作用，结果表明：水分的限制率为１８．５％，使玉米经济产量降低３９５．０１ｋｇ／ｍｕ。

Based on the solar light and thermal potential productivity of maize, the influence of water to potential productivity of maize were discussed in Shenyang region, The result showes that the watery restriction ratio is 18.5%,and water causes the economis production of maize reduced by 5925.15kg/ha.
