Abstract:

In order to select suitable shoots arid Potentilla fruticosa cutting propagation of cutting seedling matrix and growth regulator and cutting date for many breed Potentilla fruticosa seedlings to provide theoretical basis. On June 5, 2008 to July 15 healthy, no choice in born of plant diseases and insect pests of half woodiness shoots as test materials, cutting matrix and plant growth regulator, cutting time waiting for different processed Potentilla fruticosa shoots Potentilla fruticosa shoots test was conducted Potentilla fruticosa shoots, studies the influence of cutting propagation of seedling. Results show that different treatment combinations were significantly or extremely significant improvement Potentilla fruticosa shoots survival rate, at the same time for cutting seedling stage growth also have certain effect. Comprehensive view, nursery substrates as soil + mushroom medium waste of matrix is the best, plant growth regulator to 500 mg/L IBA processing Potentilla fruticosa shoots cuttings, reaches the highest survival rate 85.45%, from other comprehensive characteristic look, the concentration of NAA would handle Potentilla fruticosa shoots cuttings, survival of branch height, average rooting number, average root length is significantly higher than other combinations of growth regulator and contrast, Different date with sprigs of cutting into sprout rate is higher, but in June 5, reaches the highest cutting 88.85%.
