灌水频率对樱桃番茄生长发育的影响

Effects of different irrigation frequency on the growth and development of cherry tomato

以"旺喜"樱桃番茄为试验材料,研究了在北方春季日光温室内,不同生育期不同灌水频率对樱桃番茄生长发育、产量及病害的影响。测定并分析试验结果表明:在座果前灌水施肥频率相同,座果期到采收期灌水频率不同的情况下,随着灌水频率的减少,樱桃番茄的株高呈下降趋势;从定植到座果灌水施肥间隔4d的处理茎粗和植株干物质量明显优于其他处理,其中在定植期到采收期灌水施肥间隔均为4d的处理樱桃番茄地上部干物质量和地下部干物质量最高;灌水施肥间隔越短病害越重,间隔越长病害越轻;在定植期到座果期灌水施肥间隔为4d,座果期到采收期间隔为6d的处理最有利于产量的形成。

Cherry tomato＂Wangxi＂was used as the experimental material to study the effects of different irrigation frequency on the growth, yield and disease of cherry tomato in the spring greenhouse in northern area. The results shows that the plant height of cherry tomato decreases with the decrease of irrigation frequency under the same irrigation and fertilization frequency before fruit setting and different irrigation frequency from fruit setting to harvest. The treatment of stem coarseness and plant dry weight at four days interval from planting to fruit irrigation is superior to other treatments obviously. The above ground dry weight and below of cherry tomato is the highest when irrigation and fertilization intervals are four days from planting stage to heavier the disease is, and fertilization is four arvest stage. The shorter the interval between irrigation and fertilization is, the elonger the interval is, the lighter the disease is. The interval between irrigation ays from planting stage to Fruit setting stage, and six days is the most favorable for yield from fruit setting stage to fruit -harvesting stage.
