Cutting seedling method for single magnolia bud with leaves

Abstract

The invention discloses a cutting seedling method for a single magnolia bud with leaves. The method includes the following steps of firstly, preparing a cutting bed, wherein perlite and vermiculite are mixed to serve as a cutting matrix; secondly, preparing a shoot for cutting, wherein the distance between the lower notch of the shoot for cutting and a joint should be as long as possible, the upper notch is not lower than an axillary bud, and the shoot for cutting is soaked, washed and sterilized through bactericide after being shorn; thirdly, conducting cutting, wherein cutting is conducted after the shoot for cutting is rapidly dipped with rooting liquid; fourthly, conducting post-cutting management, wherein atomizing and bactericide spraying are regularly conducted; fifthly, conducting seedling hardening; sixthly, conducting field planting and managing, wherein field planting is conducted 1.5-2 months after seedling hardening, a rooting agent, leaf fertilizer and the like are applied in a watering mode, and then normal seedling stage nursing and managing are conducted. Single bud cutting is adopted, and therefore the cutting propagation coefficient is increased; the stem section below the joint is reserved during shoot obtaining as much as possible, the number of adventitious roots is increased, the number of roots of the single shoot can reach 7, and especially after field planting, growth of root systems and blades is scientifically regulated and controlled, and the transplanting survival rate is remarkably increased and can reach 95% or above.

Description

technical field [0001] The invention belongs to the field of plant propagation, and in particular relates to a method for growing magnolia leaves with single bud cuttings. Background technique [0002] Magnoliaceae plants are recognized as the best landscaping trees with "beautiful leaves, flowers and fruits, and wonderful color, fragrance and rhyme", and the demand for landscaping is constantly expanding. Some fine varieties are mostly propagated by grafting and cuttings. Among them, grafting propagation is limited by the amount of rootstock, and the commonly used cutting method uses branches with many buds as cuttings, and the propagation coefficient is limited. Taking single-bud cuttings can make full use of materials, increase the reproduction coefficient, and achieve a large number of seedlings, especially for some precious and rare varieties. Therefore, those skilled in the art are committed to developing a method for raising magnolia leafy single bud cutting seedlin...
