水分状况对华莱士蜜瓜幼苗生长的影响

Research on the seedling growth of Wallace honeydew melon under moisture condition

为明确水分状况对华莱士蜜瓜幼苗生长的影响,本文采用轻基质穴盘育苗的方法,通过人工称重法控制基质含水量,研究结果表明:适度干旱条件下(灌水量为常规灌水量的70%或90%)有利于华莱士蜜瓜的生长,并且华莱士蜜瓜叶绿素含量也较高,而当苗期灌水量过大时(灌水量为常规灌水量的110%)则不利于华莱士蜜瓜幼苗的生长。本研究结果为华莱士蜜瓜的合理育苗提供了技术保障。

To make clear that the influence of water status on seedling growth of Wallace honeydew melon, this research use hght media plug tray to cultivate seedlings, and through artificial weighing method to control water content. The results show that：Under the condition of moderate drought （70% or 90% irrigation water of normal amount）is conducive to the growth of Wallace honeydew melon, and chlorophyll content of Wallace honeydew melon is higher as well. While, when irrigation amount is too excessive （110% irrigation water of normal amount）,is not conducive to the growth of Wallace honeydew mdon. This study provides technical support for reasonable cultivation Wallace honeydew melon.
