SELECTION OF FORM AND PH VALUE OF NUTRIENT SOLUTION FOR WATER CULTURE OF EUCALYPT SEEDLING

This paper deals with the selection of suitable form, concentration and pH value of nutrient solution for the water culture of and E. 12ABL seedlings. The results can be summarized asfollows:1.Among the four nutrient solution forms which are of representatives i. e. Hoagland, Plonisnicofe(Лрянишников),Cronip and Walker et al. nutrient solution forms, Hoagland one is the best for the growth of the two species seedlings.2.The standard concentration of Hoagland nutrient solution is more suitable for the growth of the seedling than the others.3.The range of pH value which is suitable for the seedling grow th is 4.0~6.0 but 5.0 is the best.
