Cutting seedling culture method of pileostegia viburnoides under subtropical high-altitude climatic conditions

Abstract

The invention provides a cutting seedling culture method of pileostegia viburnoides under subtropical high-altitude climatic conditions. The cutting seedling culture method of pileostegia viburnoidesunder subtropical high-altitude climatic conditions comprises the following steps of (1) preparing cutting substrates: uniformly mixing peat soil and yellow soil to obtain mixtures to be used as the cutting substrates; (2) preparing cutting panicles; (3) performing soaking with rooting powder: soaking the cutting panicles cut in the step (2) in heteroauxing rooting powder; (4) performing cutting;(5) performing moisture management; and (6) performing illumination management. The cutting seedling culture method of pileostegia viburnoides under subtropical high-altitude climatic conditions disclosed by the invention has the advantages that the pileostegia viburnoides can be well planted at high-altitude low-temperature regions, the cutting seedling breeding speed is high, the cutting seedling culture method of pileostegia viburnoides under subtropical high-altitude climatic conditions is labor-saving, effortless and environmentally-friendly, pileostegia viburnoides seedlings are easy tosurvive after being transplanted, and the cutting seedling culture method of pileostegia viburnoides under subtropical high-altitude climatic conditions has favorable repairing effects on vegetation destruction caused by manual activities of way building, mine exploiting and the like at subtropical mountain massifs.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and specifically relates to a method for growing seedlings by cuttings of canopy vines under subtropical high-altitude climate conditions. Background technique [0002] Pileostegia viburnoides Hook.f.et Thoms. is a plant of the genus Pileostegia in the family Saxifragaceae. Evergreen climbing shrub, distributed in southern my country, growing in valley forests at an altitude of 600-1000 meters. Canopy vines have luxuriant branches, large vine leaves, strong adsorption and climbing ability, and can be used for vertical greening, suitable for wall greening of tall buildings, and also suitable for vegetation restoration on exposed slopes and other places. Cutting propagation has the advantages of simple operation, low cost, fast propagation speed, and can effectively ensure the stable inheritance of excellent traits of parents. At present, the canopy vines are all grown in low...

AI Technical Summary

Problems solved by technology

At present, the canopy vines are all grown in low-altitude areas, and the cutting method is mainly used in warmer areas. In the past, the cutting propagation of the canopy vines was mostly carried out in spring (that is, March-April every year), while in higher altitude areas, the relative temperature It is difficult to raise seedlings at low temperatures, and there is no report on raising seedlings at higher altitudes with relatively lower temperatures
