根据我国柑桔产区内110个气象站的光合有效辐射资料,计算了光能利用率分别为1％、2％、5％和10％的柑桔光合生产潜力,每亩柑桔产量可用y=K_i·U_i·Q_(par)式表示,式中y为柑桔果实产量(公斤/亩),K_i为经验系数,U_i为光能利用率(％)卧Q_(par)为柑桔生长期(≥12.5℃时期)的光合有效辐射(千卡/厘米~2·≥12.5℃)。计算结果表明,光能利用率10％的柑桔产量,除四川盆地和贵州高原外,各地都在10000公斤/亩以上,台湾南部和海南岛,高于15000公斤/亩·浙江省黄岩县,光能利用率1％、2％、5％和10％的柑桔产量分别为:1051公斤/亩、2102公斤/宙、5256公斤/亩和10515公斤/亩。最后,对如何提高光能利用率问题进行了讨论。
Based on the photosynthetically active radiation data of 110 weather stations in China’s citrus producing areas, the photosynthetic potential of citrus with light energy utilization rates of 1%, 2%, 5% and 10% = K_i · U_i · Q_ (par) expression, where y is the output of citrus fruits (kg / mu), K_i is the empirical coefficient, U_i is the light energy utilization rate (% (≥12.5 ℃ period) photosynthetically active radiation (kcal / cm ~ 2 · ≥12.5 ℃). The calculation results show that the output of citrus with light energy utilization rate of 10% is over 10000kg / mu except in Sichuan Basin and Guizhou Plateau, higher than 15000 kg / mu in Huangshan County of Zhejiang Province, The citrus yields of 1%, 2%, 5% and 10% of the light energy utilization rates were 1051 kg / acre, 2102 kg / yun, 5256 kg / acre and 10515 kg / acre respectively. Finally, how to improve the utilization of solar energy was discussed.
