基于TOMSIM模型的温室番茄中杂9号生产潜力的空间分析

Spatial Distribution of Potential Productivity for Greenhouse Tomato Variety Zhongza No.9 Based on TOMSIM

首先利用作物生长模型TOMSIM,在选择的10个地区对模型进行了区域化验证。在此基础上,利用全国各大城市1981-2000年的室外辐射资料,进行温室番茄光合生产潜力的模拟计算。结果表明,温室番茄的潜在年产量最高值在西藏,为57kg.m-2,最低值在重庆,为34kg.m-2。将潜在产量与实际产量数据进行比较,发现全国平均的实际产量仅占潜在产量的7.7%,说明温室番茄的生产有较大的潜力空间。

Potential productivity of greenhouse tomato variety Zhongza No. 9 was calculated by using TOMSIM model to guide production of greenhouse tomato. At first the mechanism of TOMSIM was introduced and tested by using the 10 sites radiant data of China. Then the potential productivity of greenhouse tomato variety Zhongza No. 9 were simulated by inputting 33 cities solar radiation data of China from 1981 to 2000. The results showed that the highest yield equal to 57kg·m^-2 was in Tibet and the lowest equal to 34kg·m^-2 in Chongqing. The average actual yield of the tomato was only 7.7% of the average potential productivity, which revealed that the enormous output potential of greenhouse could be utilized.
