| 摘 要： | 采用负压控水系统将土壤水分控制在不同的水平上, 研究了亏缺灌溉对草莓果实特性、植株生长和产量形成的影响。随着土壤水分的降低, 植株的株高、叶片数、结果数、产量和单果质量逐步减少。不同土壤水分处理条件下果实的理化特性明显不同, 亏缺灌溉降低了果实含水量, 提高了果实硬度、可溶性固形物含量(Brix) 、滴定酸度、糖酸比、维生素C 含量。相关分析表明, 果实的鲜样质量、直径与土壤水分含量呈显著的正相关, 而可溶性固形物含量(Brix) 、糖酸比与土壤水分含量呈显著的负相关。

| Abstract: | The effects of soil moisture on the plant growth,yields,physical and chemical properties of strawberry fruit were studied by use of a new auto irrigation system of negative pressure. It was showed that plant height,number of leaves,fruit weight,fruit diameter,fruit number and yields gradually decreased with the decreasing of soil moisture.The physical and chemical properties were apparently different under different soil moisture treatments.The Deficit Irrigation decreased water content of fruit,increased fruit hardness,soluble solid content,titratable acidity,sugar acid ratio and the content of ascorbic acid.The correlation analysis indicated that soil moisture has a positive correlation with the fruit diameter and weight,but has a negative correlation with soluble solid content and sugar acid ratio. |
