Method for preparing substrate and seedbed for cuttage growth of big fruit sea-buckthorn twigs

Abstract

The invention relates to a method for preparing a substrate and a seedbed for cuttage growth of big fruit sea-buckthorn twigs. The method includes the following steps: step I. selecting a nursery ground: the soil type is loam; step II. selection of soil inserting: selecting a plot with high soil fertility and good ventilation and water permeability as soil inserting in the nursery land; step III.making a bed: the nursery adopts a high bed with the height range of the bed being 8-15cm, the width of the bed being 120cm, and the periphery of the bed being built by bricks; step IV. preparing a growth substrate: filling the prepared seedbed with the growth substrate used for cuttage, wherein the growth substrate is pure quartz sand, and the thickness range is 8-15cm; step V. disinfection: spraying a ferrous sulfate aqueous solution and a potassium permanganate aqueous solution for disinfection; step VI. cuttage: inserting the processed cuttings into the growth substrate; and step VII. spray irrigation. According to the method, the growth substrate and seedbed for cuttage growth of big fruit sea-buckthorn twigs are improved, and the growth substrate is changed every year, so that the problems of high cost and low cutting survival rate of the existing twig cuttage can be solved.

Description

technical field [0001] The invention relates to the field of configuration of growth substrates and seedbeds, in particular to a method for configuring growth substrates and seedbeds of seabuckthorn twig cuttings. Background technique [0002] Twig cuttings are an important means of asexual and rapid propagation of Hippophae rhamnoides L., and the growth substrate is the key to successful propagation of Hippophae rhamnoides twigs. The growth matrix structure of the existing seedbed is 3 layers, the lower layer (base layer) pebbles, 15-20 cm in thickness; the bean paste in the middle layer, 10-15 cm in thickness; [0003] The existing seedbed growth substrate is used for twig cuttings of large-fruited seabuckthorn. First, the cost of making the bed is high, and the cost of cleaning or treating the seedbed is higher; However, the survival rate of seabuckthorn tender branch cuttings in the second year is 50%, and the survival rate of sea buckthorn tender branch cuttings in the...

Problems solved by technology

[0003] The existing seedbed growth substrate is used for twig cuttings of large-fruited seabuckthorn. First, the cost of making the bed is high, and the cost of cleaning or treating the seedbed is higher; However, the survival rate of seabuckthorn tender branch cuttings in the second year is 50%, and the survival rate of sea buckthorn tender branch cuttings in the third year is even lower. In order to achieve the purpose of rapid propagation, the growth substrate needs to be replaced every year. Among them, the growth substrate determines the Survival rate, the reason why the survival rate drops a lot in the second year is that the growth substrate is not thoroughly sterilized, and there are pathogenic bacteria or viruses
