以聚乙烯醇为聚合体与甘油反应制得水凝胶,以水凝胶为载体加入生根激素,最后制得高分子·激素水凝胶,将其涂在插穗上面水凝胶干燥后在插穗表面形成一层薄膜,防湿水,可以缓解释放出激素刺激插穗生根,从而达到延长插穗生根临界期,提高插穗生根成活率的目的。
Polyvinyl alcohol is reacted with glycerin to obtain a hydrogel, hydrogel is added as rooting hormone, and finally a polymer hydrogel is prepared, which is applied to the hydrogel on the cuttings to dry, The surface of a thin film, moisture-proof water, can relieve the release of hormones to stimulate cuttings rooting, so as to extend the cuttings rooting critical period and improve the survival rate of cutting root.
