摘要
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”。
An experiment is carried out in a greenhouse with controlled temperatures of 25C ,30C, and 35C, respectively. The results show that in greenhouse dry matter production increases with growth developing suitable temperature. During the earlier growing stage, NAR, LAI and total dry matter weight are the highest at 30C, and it is suitable to dry matter to concentrate in fruit. During the growing anaphase, NAR, Lai and total dry matter weight are the highest at 35C , and it is suitable to dry matter to concentrate in fruit. Temperature has no significant influence on total distribution of dry matter during the whole growing period. According to this, 'the view of the dry matter distribution balance' was put forward.
