土壤水分对番茄生长发育及产量品质的影响

Effect of Soil Water on the Growth, Development Yield and Quality of Tomato

以“L402”为试验材料,研究了土壤水分对番茄生长发育及产量品质的影响。结果表明,80％土壤水分 可显著提高番茄株高、茎粗及各器官鲜物重,但座果率较50％土壤水分处理番茄为低,而番茄灵处理可显著提 高80％与65％土壤水分处理的番茄座果率,并显著提高其产量,但对50％土壤水分处理的番茄没有显著影响。 本试验自然坐果条件下,80％、65％水分处理的番茄产量分别比50％处理高35．31％、27．73％,而采用番茄灵 处理后,则前者的产量分别比后者增加70．76％和38．98％。

Taking “L402” as the test material, the effect of soil water content on tomato growth, yield and quality was studied. The result indicated that the plant height, stem diameter and the fresh weight of organs of tomato growing in 80% soil water were higher, but the fruit setting rate lower than that of tomato growing in 50% soil water, and PCPA could enhance the fruit setting rate and yield of tomato growing in 80% and 65% soil water significantly, but having no effect on tomato growing in 50% soil water. The yield of tomato dealt with 80%, 65% soil water treatment was higher by 35.31%, 27. 73% than that of 50% respectively, moreover by 70. 76% and 38.98% after dealing with PCPA, respectively.
