摘　　要：在参考国内外园艺作物生长发育模拟模型研究的基础上,结合温室黄瓜试验数据,确定模型参数,建立了温室黄瓜光合生产与干物质积累模拟模型,其中包括光合,呼吸和干物质生产等子模型。通过对温室黄瓜进行活体定株观测和取样测量,在不同播种期(春季和秋季)和不同处理光强(100%光照和33%光照)下验证模型的准确性,表明模型具有较高的精确性、灵敏性和实用性。Referred to the results from both abroad and at home,a simulation model of greenhouse cucumber for photosynthesis and dry matter accumulation was developed.The model includes sub-models for photosynthesis,respiration and dry matter production.Through living and stable plants sampling and observation,the model was validated for two growing seasons(spring and autumn) and with two different light intensity treatments(100% and 33%).According to the experimental data,some of model parameters were determined.The results showed that the model was of high accuracy,sensitivity and practicability.
