| 摘 要： | 以"紫罗兰"紫甘薯为材料,薯苗扦插成活后30d叶面喷施50mg/L、150mg/L和250mg/L三种浓度PP333溶液,并以清水作对照.用药后7d测定叶片叶绿素含量;种植3.5月采收后测定产量和品质.结果表明:三种浓度PP333处理中,150mg/L为最佳,增产率19.37%,花青素含量、淀粉含量、可溶性糖含量分别较对照提高9.60%、17.87%、11.06%,含水量降低1.60%,各项指标的影响较对照均达显著水平.

| Abstract: | With ＂ violet＂ purple sweet potato as experiment materials, after the cutting seedling survived 30 days, the effect of PP333 on the yield and quality of purple sweet potato was studied by means of foliar spraying 50 mg/L, 150 mg/L and 250 mg/L PP333 liquid. The results indicated 150mg/L was the best treatment, it could promote yield 19.37%, anthocyanin content 9.60 %, starch content 17.87%, soluble sugar content 11.06% and reduced water content 1.60%. |
