温室黄瓜不同栽培形式和密度，直接影响产量，其原因是产量采自基本的主理过程。如光合、呼吸、传导作用、离子吸收、蒸腾、色素形成、生长发育、开花结果等许多过程。不同的栽培形式和密度，促进或阻碍这些过程的进行。如栽培形式和密度不同，２号小区株行距２７ｃｍ×６０ｃｍ４１６７株／６６７ｍ２，比３号小区株行距４０ｃｍ×６０ｃｍ２７７８株／６６７ｍ２，前期产量增１４．５７％，总产量增３１．２４％。２号小区比３号小区霜霉病晚发生１８天，病情指数降低１２．２４。所以栽培形式和密度不同．群体结构不同，在不同生长发育阶段中，对光、热、水分、离子吸收均不同。其结果必然是产量和发病轻重都不同。关键词
Greenhouse cucumber cultivation in different forms and density, a direct impact on yield, the reason is that the production from the basic principle of the process. Such as photosynthesis, respiration, conduction, ion absorption, transpiration, pigment formation, growth and development, flowering and many other processes. Different forms and densities of cultivation promote or hinder the progress of these processes. For example, the plot size and density of No.2 plots were 27cm × 60cm4167 / 667m2, which was 40cm × 60cm2778 / 667m2 higher than that of No.3 plots. The yield of early stage increased by 14.57% and the total yield increased by 31.24%. Community No. 2 cell downy than No. 3 occurred 18 days later, the disease index decreased 12.24. Therefore, different forms of cultivation and density. Group structure is different, in different stages of growth and development, the light, heat, moisture, ion absorption are different. The result is necessarily different in terms of yield and severity. Key words
