Abstract
Taking Cymbidium Wenshanense as the research object,randomized block experiment was used.The change of the photosynthetic physiological characteristics and nutrient content of orchid by fertilized with 3 different foliar fertilizer(Potassium Dihydrogen Phosphate,Biogen,Cuijun B-2) was studied.The aim is to provide reference for the cultivation technique of Cymbidium Wenshanense.And the results showed that: 1.To Cymbidium Wenshanense,when the treatment concentration of Cuijun B-2 at dilution of 1:500,in indexes of photosynthetic physiology,the value of net photosynthetic rate,stomatal conductance,transpiration rate,is relatively larger,while the value of intercellular CO2 concentration is relatively smaller,the photosynthetic efficiency was high,which was beneficial to fast growth. 2.The content of total N,total N P and total N K in Cymbidium Wenshanense was improved when 3 fifferent fertilizer were applied.The effect of Cuijun B-2 was applied better than Potassium Dihydrogen Phosphate and Biogen,which was beneficial to fast growth.
