利用树木枝条扦插育苗,能保持母株原有优良性状,经济林能提早结果,是一条多快好省的育苗途径。现介绍几种促早生根、多生根、提高成活率的新方法。1.浸肥水催根:将剪好的插穗浸入0.1～0.2磷酸二氢钾肥水中12～14小时,让其吸足肥水后再扦插,可促使生根快、发芽早、成活率高。 Cuttings using tree branches cuttings, can maintain the original good characteristics of the mother plant, economic forest can be early results, is a much faster and better province of seedling. Now introduce several kinds of early rooting, more roots, improve the survival rate of new methods. 1. Baptist fertilizer forcing: the cuttings will be immersed in 0.1-0.2 potassium dihydrogen phosphate fertilizer water 12 to 14 hours, let them absorb enough fertilizer and then cutting, can promote fast rooting, early germination, high survival rate.
