在总结山东省寿光市五台镇农民日光温室黄瓜高产栽培经验的基础上 ,分析了各项技术对改善生长环境及叶片光合特性的作用。研究结果表明 ,高产栽培技术的实施 ,提高了土壤的肥力水平 ,增加了室内CO2 浓度 ,延长了植株叶片高光合速率的时间 ,黄瓜功能叶片的光补偿点降低 ,光饱和点升高 ,羧化能力加强 ,并延缓了叶片的衰老 ,从而为日光温室黄瓜高产技术提供了科学依据。 On the basis of summing up the cucumber cultivation experiences of farmer greenhouse in Shouguang City, Shandong Province, the effects of various techniques on improving the growth environment and photosynthetic characteristics were analyzed. The results showed that high-yielding cultivation techniques increased soil fertility, increased indoor CO2 concentration, prolonged the high photosynthetic rate of plant leaves, decreased light compensation points of cucumber functional leaves, increased light saturation point, carboxylation Ability to strengthen and delay the leaf senescence, thus providing a scientific basis for high yielding cucumber technology in solar greenhouse.
