寒地中棚草莓早熟栽培技术研究

STUDIES ON THE CULTIVATION TECHNIQUES FOR STRAWBERRY EARLY MATURING IN COLD FIELD COVERED WITH SHED

本文对扣棚和露地栽植草莓的环境因子、物候期、生长状况、开花结果习性、产量和品质进行研究。结果表明:扣棚可显著提高气温、地温及湿度,物候期比露地提早8d^10d,产量提高近15.6%,但扣棚草莓的无效花数增多,花朵座果率和果实含糖量均有所下降。

The environmental factors,phenology,growth,flowering,fructing,yield and quality of strawberry cultivated in the field covered with shed and in the open field were investigated and analyzed. The results showed that the atmospheric temperature,soil temperature and humidity in the field couered with shep can be increased significantly,the phenological period can be moved up by 8-10days compared with open field. The yield was increased by 15.6% ,however,invalid flowers of strawberry in the field covered with shed were increased,fructifying rate and sugar content in fruits wiere decreased a little.
