Abstract

Abstract: Two-month-old tissue culture plantlets of Zhongke Mizhen No.2 were used to study the effects of different proportions of foliar fertilization combined with plant type control on stem diameter growth, chlorophyll content, nitrogen, phosphorus and potassium content, and seedling physiological indicators. The results showed that stem diameter, chlorophyll content, total nitrogen and potassium contents and root-to-shoot ratio were significantly different among different treatments, while total plant phosphorus content was not significantly different among treatments. Among the four control factors, plant type control had the greatest promoting effect on the growth of tissue-cultured seedlings of Zhongke Mizhen No.2. The optimum treatment formula for Zhongke Mizhen No.2 was plant type control combined with application of compound foliar fertilizer （0.2% urea + 0.1% monopotassium phosphate + 0.2% horticultural fertilizer）.

Key words: Zhongke Mizhen No.2, foliar fertilization, plant type control, kiwifruit, tissue culture seedling, growth and development, physiological indicator
