| 摘 要： | 对日光温室春茬基质培韭菜的基质含水率进行了研究,结果表明基质相对含水率高于60%可获得韭菜的高产和稳产,同时有利于增加韭菜茎粗和叶宽。基质含水率对韭菜N、P、K三要素的吸收和肥料的利用率有影响,基质含水率高有利于P和K的吸收,对N的促进在基质含水率低于50%以下时明显。随基质含水率增加,NPK肥料的利用率增加,PK肥相对于N肥比例增加。经韭菜产量与灌水量回归分析,还得出日光温室春茬基质培韭菜各时期的适宜灌水范围。

| Abstract: | Influence of water content of growing media on yield and growth of Chinese chive in spring greenhouse was studied.The results showed that 60% RWC of water content could obtain high yield,big diameter of stem and large width of leaf.Total N,K content reduced and total P content increased in dry Chinese chive with water supply decreasing.The optimum range of the amount of water used in growing media was recommended in greenhouse in spring by regression equation between amount of water used and yield of Chinese chive. |
