扦插法是无性繁殖中一种常用的方法。然而对很多植物来说,成活率往往都很低。如何使插条提前生根,研究很多,最有效的是利用生长激素对插条进行处理。但在广大农村,目前受条件的限制,这种方法仍难于普遍推广。据报道,过去曾有人试验在插条基端割条裂缝,嵌入一粒小麦种子,插入土内后,借麦粒发芽生根来促进插条不定根的发生。在此启发下,我进行了几年实验,采用将插条扦插在植株根部,由于是借用活体植株的根来影响插条成活,因此将这种方法称作“借根”扦插法。 1.实验材料的选取取月季、玫瑰、石榴、茉莉、栀子花、瑞香、夜来香等一年生或多年生枝条,各保留3～5个节,且腋芽饱满,剪去部分叶片,以减少蒸腾。将枝条下端剪成斜面待用。 Cutting method is a common method of asexual reproduction. However, for many plants, the survival rate is often low. How to make cuttings in advance rooted in many studies, the most effective is the use of growth hormone cuttings for processing. However, in the vast rural areas, due to the current restrictions, this method is still difficult to universally promote. It has been reported that in the past, it was reported that in the cuttings at the base end of the cuttings, cracks were embedded in a piece of wheat seeds and inserted into the soil, adventitious rooting was promoted by germination and rooting of wheat grains. Inspired by this, I conducted several years of experimentation by cutting the cuttings at the root of the plant and by using the roots of the living plants to influence the survival of the cuttings. This method is therefore called “rooting” cutting. 1. Selection of experimental materials Take annual or perennial shoots such as rose, rose, pomegranate, jasmine, gardenia, daphne, and evening primrose with 3 to 5 knots each, and full axillary buds to cut off some leaves to reduce transpiration. Cut the lower ends of the branches into bevels.
