不同处理对旱柳扦插繁殖的影响
Effect of Different Treatments on Cutting Propagation of Salix matsudana Koidz.
摘要
Abstract
[Objective] The aim was to discuss the optimum rooting conditions for the cutting propagation of Salix matsudana Koidz.. [ Method ] The effect of different substrate, cutting diameters, rooting agent, temperature and humidity on the rooting of Salix matsudana Koidz. Cuttings were studied. [ Result ] In the mixed substrate of 1/4 garden soil and 3/4 peat, the rooting rate of Salix matsudana Koidz. Cuttings was the maximum of 98.48%, and the average root quantity was the largest of 5.99; while in the mixed substrate of 1/2 saline-alkali soil and 1/2 peat substrate, the average root length was the largest of 3.06 cm. 1 000 mg/L of IBA promoted the rooting rate of Salix matsudana Koidz to as high as 100% , and improved the average root number and length of the cuttings. The temperature and humidity inside and outside of the greenhouse had great impact on the rooting of Salix matsudana Koidz. Cuttings, inside of the greenhouse, the rooting rate of the cuttings was 94.90% , the average root number was 4.41, and the average root length was 2.35 cm, which was obviously higher than that outside of the greenhouse, the cuttings inside of the greenhouse were easy to survive. The diameter of Salix matsudana Koidz. Cuttings had slight influence on its rooting, and the rooting effect of the middle and base section of Salix matsudana Koidz. Cuttings was good. [ Conclusion ] The middle and base sections of the Salix matsudana Koidz. Were selected to be the cuttings, which had good rooting effect in the mixed substrate of garden soil and peat in the greenhouse by adding certain concentrations of rooting agent.关键词
