Lonicera caerulea cutting medium seedbed and lonicera caerulea cutting propagation method

Abstract

The invention relates to the technical field of lonicera caerulea propagation, in particular to a lonicera caerulea twig cutting medium seedbed and a cutting propagation method. The lonicera caeruleacutting medium seedbed comprises a substrate layer and a surface layer, wherein the surface layer is positioned on the surface of the substrate layer; the substrate layer comprises fine river sand, larch needles, sawdust and garden soil, and the volume ratio of the fine river sand to the larch needles to the sawdust to the garden soil is (1.8-2.2): (0.4-0.6): (0.4-0.6): (0.8-1.2); and the surfacelayer comprises larch needles and saw dust, and the volume ratio of the larch needles to the saw dust is (0.4-0.6): (0.4-0.6). When the cutting medium seedbed is used for lonicera caerulea cutting propagation, the cutting medium seedbed is good in moisture retention performance, high in nutrient, high in rooting rate and survival rate, capable of being directly used for bed reserving for overwintering (high in preservation rate), low in cost, simple in raw material, suitable for factory-like seedling propagation and particularly beneficial to seedling strengthening and increasing of the survival rate in the bed moving and seedling hardening process.

Description

technical field [0001] The invention relates to the technical field of Lonicera indigo Lonicera propagation, in particular to a twig cutting substrate seedbed for Lonicera indigo Lonicera and a cutting propagation method. Background technique [0002] Lonicera indigo Lonicerae is one of the most representative edible small berries in my country. For a long time, the cutting propagation method of L. indigo mainly uses moss or fine river sand as the cutting substrate. Bryophytes are a kind of higher plants with simple structure. They are the only group of higher plants without vascular bundles. They are also a transitional form from aquatic to terrestrial. They are the most primitive group of higher plants. Moss has high requirements for a suitable environment, and it cannot be planted artificially at present. The use of moss as a cutting substrate has the following disadvantages: (1) In recent years, with the artificial destruction of the moss population, its population has...

Problems solved by technology

Moss has high requirements for a suitable environment, and it cannot be planted artificially at present

The use of moss as a cutting substrate has the following disadvantages: (1) In recent years, with the artificial destruction of the moss population, its population has shrunk, and the market price has also increased year by year. It is currently close to 20 yuan / kg, and moss is used as a cutting substrate. , although the rooting rate of cuttings can reach about 70%, but the price is expensive, the cost is too high, and the ecological environment is seriously damaged. Most cities in my country have banned moss harvesting in recent years, resulting in a shortage of raw materials.

(2) Moss has the advantages of moisturizing, breathable, and easy to use. It has active factors, which are good for inducing the root system. However, once the water is too much, it will cause the substratum to collapse, resulting in poor air permeability, root development and aging, and then affect the growth of the aboveground part.

Fine river sand is an inorganic substrate. Although it has good air permeability and is also suitable for the root development of cuttings after rooting, it has the following disadvantages: (1) Fine river sand itself does not have functions such as heat preservation and providing nutrients for plant growth and development. No active factor

It is not suitable for plant growth and development at the later stage of rooting of cuttings, and cannot provide assistance for plants in establishing an effective biological cycle

(2) After the root system of cutting seedlings reaches a certain degree of lignification, the management of bed removal must be carried out immediately, which may easily cause death of seedlings during the process of bed transfer and seedling training

(3) Because the river sand itself does not have water retention, the sand bed must be in charge of by a special person, and it must be watered every 20 minutes, and the field management cost is high

[0003] To sum up, moss is currently used as the cutting substrate, although the rooting rate is high, but there are serious problems such as lack of raw materials, high cost, and damage to the ecological environment; while using fine river sand as the cutting substrate, although the cost is low, but The matrix itself has no nutritional components and moisturizing functions, which makes manual management difficult in the later stage. Management costs are high, and the quality of seedlings cannot be guaranteed, which restricts the development potential of industrialization.
