试验设25℃、30℃、35℃三种温度处理,研究结果表明:大棚黄瓜的干物质生产随生育发展适温提高,果实的干物质含量随温度升高而降低.30℃温度处理在生育前期的NAR、LAI及总干重量最高,最利于干物质向果实分配,35℃温度处理在生育后期的NAR、LAI总干重最高,最利于干物质向果实分配。温度对全生育期的干物质总分配无显著影响。据此,笔者提出了“干物质分配平衡论”。 The experiment was conducted at 25 ℃, 30 ℃ and 35 ℃. The results showed that: the dry matter production of greenhouse cucumber increased with the growth and development of suitable temperature, and the dry matter content of fruit decreased with the increase of temperature. The highest NAR, LAI and total dry weight in the early stage were the most favorable for the distribution of dry matter to the fruit. At 35 ℃, the NAR and LAI in the late growing stage had the highest total dry weight, which was the most favorable for the distribution of dry matter to the fruit. Temperature had no significant effect on the total dry matter distribution during the whole growth period. Accordingly, I put forward the “dry matter distribution balance.”
