摘要
设置6个不同营养液配方研究了石斛兰营养生长和开花情况。结果表明:石斛兰在5~8月为旺长期,需养分为每周每株N1.76mg、P0.47mg、K2.10mg、Ca1.54mg、Mg0.95mg。正常生长植株茎叶养分含量为N1.18%、P0.31%、K1.62%、Ca1.28%、Mg0.68%。本试验的条件下,完全配方处理的植株生长发育和开花正常,最佳配方是N∶P∶K为15∶30∶15的完全营养液并加腐殖酸。每周喷施(3%)1~2次为宜。
The vegetation growth and blooming of Dendrobium has been studied with six kinds of nutrient solution composition.The results indicated that the vigorous growth period of Dendrobium was from May to August. The nutrient requirement per plant in each week was N 1.76mg,P 0.47mg,K 2.10 mg,Ca 1.54mg and Mg 0.95mg,respectively.For normal bloom,the nutrient concentration in the shoot were N 1.18%,P 0.31%,K 1.62%,Ca 1.28% and Mg 0.68%,respectively.The optimum nutritive composition was the complete nutrient solution with N,P,K and humic acid(N∶P∶K=15∶30∶15).It was suitable to spray 0.3% fertilizer solution 1-2 times in each week.
