A kind of cutting seedling raising method of Begonia variegata

Abstract

The invention discloses a cutting seedling method for malus toringoides. The cutting seedling method for the malus toringoides comprises the following steps of treating a cutting bed; laying cobblestones under the cutting bed; laying a window gauze on the cutting bed; laying mixing materials comprising nutrient soil and perlite on the window gauze; sterilizing soil; shearing semi-lignified branches, which grow normally, are not affected by plant diseases and insect pests and have plump buds, from a malus toringoides seed tree with the age about 10 years; timely bringing back the branches and manufacturing cutting slips; performing earlier-stage treatment on the cutting slips and performing cutting; and performing management after cutting. By using the cutting seedling method, the operation is simple, the yield is high, requirements on production of nursery-grown plants of the malus toringoides can be met, and the nutrient soil 3 and the perlite 1 serve as a cutting medium which is loose and breathable, has rich nutrition and can provide nutrition for the nursery-grown plants during earlier-stage growth. After the cutting slips are rapidly dipped in 1200mg / L of naphthaleneacetic acid liquor, cutting can be directly performed on the cutting slips, the cutting time is shortened, and the work efficiency is improved; the cutting yield is higher than 90%; the nursery-grown plants grow healthily and strongly; and the excellent performance of the maternal malus toringoides is kept. Compared with a seed raising method, the cutting seedling method has the advantages that cutting propagation is not limited by seasons, branches can be treated by cutting immediately after being shearing from the tree, and the operation is simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a method for growing seedlings of crabapple by cuttings. Background technique [0002] Malustoringoides is a species of Malustoringoides in the family Rosaceae (Malus) and is mainly distributed in the southeastern margin of the Qinghai-Tibet Plateau. The leaves of this tree species are rich in various nutrients and have the effect of reducing "three highs". [0003] Variegated Begonia is mainly used for sowing and raising seedlings. Two documents published in "Forestry Practical Technology" (2006, (9): 31-32) and "Chinese Patent" (2013, 2, 24) have analyzed the Sowing and raising seedlings is introduced in detail, but the cutting propagation of Begonia variegata has not been involved. [0004] Sowing seedlings is a common method of raising seedlings in production, but seedlings grow slowly, take a long time to raise seedlings, have large inter-i...
