运用扦插育苗既能保持母株的优良性状,经济林又能提早结果,是一种多快好省的育苗途径。现介绍几种促进早生根、多生根,提高成活率的新方法 1 浸肥水催根:将剪好的插条浸入10～20％磷酸二氢钾水溶液中12～14小时,让其吸足肥水再扦插,可促使生根快,发芽早,成活率高。 2 预处理:硼素有促进插条生根之效,和激素合用效果显著,如用吲哚丁酸50ppm加硼素10～200ppm处理插条12小时,生根率显著提高。
The use of cutting seedlings can not only maintain the excellent traits of mother plants, economic forest and early results, is a fast and good province of seedling. Now introduce several new methods to promote early root, more root, improve survival rate of a new method of fertilizing water: Cut the cuttings immersed in 10 to 20% potassium dihydrogen phosphate solution for 12 to 14 hours, let it absorb enough fat Re-cutting, can promote rapid rooting, germination early, high survival rate. Pretreatment: Boron has the effect of promoting the rooting of cuttings, and the combination effect of hormones is remarkable. For example, when using indole butyric acid 50ppm plus boron 10-200ppm for 12 hours, the rooting rate is significantly increased.
