摘要
为了明确结果期水分调控对樱桃番茄产量和品质的影响,以千禧和红玉为试验材料,对不同土壤相对含水量(40%~50%、60%~70%、80%~90%)下日光温室冬春茬和秋冬茬樱桃番茄品质、产量和水分利用效率进行研究。结果表明,随着土壤相对含水量降低,樱桃番茄的果实可溶性固形物、可溶性糖、可滴定酸、VC含量显著提高,水分利用效率也明显提高;但叶片净光合速率、气孔导度、叶绿素含量以及单果质量、产量随着土壤相对含水量降低呈现出先增加后降低的变化趋势。通过熵权法和TOPSIS法相结合,综合分析樱桃番茄品质、产量和水分利用效率各项指标,得出樱桃番茄结果期最佳土壤相对含水量为40%~50%。
In order to figure out the effect of water regulation during fruiting period on cherry tomato yield and quality,this paper took cherry tomato‘Qianxi’and‘Hongyu’as experimental material and studied the effects of 3 treatments with different relative soil water contents(40%-50%,60%-70%,and 80%-90%)on cherry tomato quality,yield and water use efficiency in winter-spring crop and autumn-winter crop in solar greenhouse.The results showed that the contents of soluble solids,soluble sugar,titratable acid,VC and water use efficiency of cherry tomato were significantly increased along with the increasing of soil relative water content.But,the leaf net photosynthetic rate,stomatal conductance,chlorophyll content,single fruit weight and total yield would show a changing tendency of first increasing then decreasing along with the reducing of soil relative water content.Combining entropy weight method with TOPSIS method,the paper comprehensively analyzed various indexes of cherry tomato including quality,yield and water use efficiency.The optimum relative soil water content was 40%-50%during cherry tomato fruiting period.
