摘　　要：试验采用美国CID公司生产的CI-301光合作用测定仪,以四个南瓜自交系为试验材料,测定了其春季的净光合速率以及其生理生态因子。结果表明,此期间南瓜的净光合速率呈先上升后下降趋势,光合有效辐射最大值出现在5月30日,为1212.03μmol.m-2.s-1;平均叶温和气温均逐渐升高,且叶温高于气温。Using CI-301 photosynthesis measure system made in CID Corporation of America and looking four pumpkins inbred lines as the material,the experiment has measured pumpkin s net photosynthetic rate as well as its physiology ecological factors in spring so that scientific and guidable suggestion can be provided for cultivation and management of pumpkin.In the period,pumpkin s net photosynthetic rate was the single-peak curve,Photosynthetic active radiation,s maximum value appears in May 30,is 1212.03μmol·m-2·s-...
