| 摘 要： | 为了探求日光温室渗灌条件下青椒适宜的土壤水分控制下限,采用温室小区试验的方法在青椒全生育期内采用土壤体积含水率作为控制指标,研究了不同土壤水分对青椒的长势、叶绿素、耗水量、产量、水分利用率的影响。结果表明,不同土壤水分对青椒株高无显著影响,对茎粗的影响是5%显著水平和1%极显著水平。相同生育阶段青椒叶绿素含量随土壤水分控制范围降低而增加。在(55%~65%)θf处理下青椒的产量最高,而且水分生产率分别为(65%~75%)θf和(75%~85%)θf处理下的1.2倍和1.4倍。

| Abstract: | In order to obtain the reasonable soil moisture limit for pepper under subsurface irrigation in greenhouse,this paper did a field research about the effects of soil moisture on pepper growth,water consumption,yield,water use efficiency and chlorophyll content through pepper growth in greenhouse,taking soil moisture content as control index.Results show that the different soil moisture content had no significant influence on the pepper height,and had on pepper diameter with significant level of 5% and 1%.In ... |
