喷施CO_2对黄瓜生理代谢影响研究初报

施用CO_2气体肥料,能提高塑料大棚内栽培黄瓜产量20％左右。喷施CO_2气体后能引起黄瓜生理代谢一系列变化,首先是气孔开放度增加,光合产物糖的积累也明显增高。从生长上测定株高,叶面积也有扩大。生长与前期氮代谢加速有关,测得全氮含量也有不同程度提高。

Effects of application of CO_2 to the metabolism of cucumber

CO_2 is cne of the raw materials in photosynthesis and influences this process directly.The output of the cucumber growing in plastic tent increases evidently after CO_2 application.Treated plants always show more promotive in a series of physical changes and physiological reactions than c.k;the stomatal opening bigger,the enlargement of the area of leaf faster and the quantity of sugar,especially the photosynthesitic product is enhanced obviously by about 22.31% on average. Poet.M.M reports that CO_2 has great effects on lettuce the infliuences are reflected in increase of output,earlier ripeness and enlar.gement of the area(about 40 percent higher). The same results havt been obtained in our experiment.
