摘要
以 2年生玫瑰红苹果为试材 ,对盆栽苹果施肥试验进行了研究 ,比较了不同肥料种类和不同施肥浓度对盆栽苹果生长以及盆土溶液电导率和 pH值的影响。结果表明 ,自 4月 2 0日开始 ,每周浇 1次 2 0 0倍的麻酱渣上清液以及在此基础上每 2周加喷 1次 0 .1%的尿素 ,均能促进盆栽苹果的生长。并且随着施肥浓度的增加 ,盆土溶液电导率增高 。
The experiment was conducted in potted fruit garden of agricultural university of Hebei. The effects of fertilizers and their concentrations on the growth and development of two-year-old rose-red Apple and conductivity and pH values of soil solution were compared in the study. The results showed that, from 20, April, the application of fermented solution of 200 water: 1 sesame dregs every week and/ or foliar spray of 0.1% urea every two weeks promoted the growth of the apples cultivated in pots. Moreover, as the concentration of the fermented sesame dregs solution increased, the conductivity of soil solution increased and the pH value decreased.
