Abstract

The invention provides a cutting propagation method for Brachychiton rupestris. The propagation method mainly utilizes the branches of the Brachychiton rupestris, and comprises the following steps: selecting a time for taking the branches, selecting healthy cutting branches and a cultivating container, preparing cultivating soil, potting, putting the cultivated seedlings in a sunny natural lighting environment, and watering with a proper amount of water; after 3 months, a part of root system can grow out from bottom holes of the cultivating pot; and by measuring, the trunk part of the seedlings after being cut for two years can be thickened by 8mm. Brachychiton rupestris is a famous succulent plant ornamental tree species in the world, and has beautiful leaves, little damage by disease and insect, slow growth and ornamental value, and the diameter at breast height of a lumber tree species is greater than 1m. In the place of origin, the tree age for a Brachychiton rupestris seed to grow into a tree with the diameter at breast height greater than 1m is 50 years, so far, only seed propagation is adopted. The cutting propagation method improves the growth speed of the Brachychiton rupestris, shortens the seedling raising time, overcomes the problem of long growth period of the seedling, and enables the precious ornamental tree species to propagate quickly.

Description

Cutting propagation method for Brachychiton rupestris
Technical field
The present invention relates to Queensland's bottle and do the cuttage breeding method of tree, belong to the plant asexual multiplication technology field.
Background technology
Queensland's bottle is done tree Brachychiton rupestris, Sterculiaceae bottle Pterostyrax, Australia endemic tree, the bearing tree body bodily form is very large, the likeness in form bottle, has very high ornamental value, one strain is through the sapling of sowing, and trunk just can expand gradually after growing 15 years usually, and the plant with certain ornamental value, the age of tree all should be more than 50 years, these seeds are botanical gardens, first-selected ornamental tree species precious in the scape is made in torrid areas park and garden construction and the greening of modern leisure agriculture, and the plant that common import one strain has ornamental value is all more than tens0000 yuan, even hundreds of thousands unit, and to pass through lifting, transportation, the process of field planting, if it is improper to nurse, will cause plant injured, with all that has been achieved is spoiled, some places are done Queensland's bottle that can have a strain health and are set the jewellery of looking that is, are called the treasured in shop, town or garden, town.Queensland of the present invention bottle is done the cottage propagation technology of tree, has shortened seedling raise period, and moulding is fast, the rate of growing seedlings height, overcomes seed seedling long problem in vegetative period, has also solved the difficult problem of the dried tree of China's Queensland's bottle resource sleepiness.
Summary of the invention
Queensland's bottle is done the cuttage breeding method of tree, its characteristics are at first to choose gets bar opportunity and cutting, the wound at cutting two ends is through after airing, disinfecting, select suitable container and substrate culture, must be placed on sun-drenched environment after cultivation is good, it is many that branch after the cultivation is disliked water, the humidity of matrix uses " suction type soil moisture " to measure soil wetness>50Kpa, can bear new root in 45-50 days, transplant after 80-90 days, the seedling trunk position of cuttage after 2 years increases thick 8-9 millimeter, and be faster than the moulding of seed seedling.
More detailed content is: its characteristics are at first to choose and get the bar time, carry out before Chun Mo Queensland bottle is done tree vigorous growth arrival, and the wound of pruning does not have a large amount of nutrients and overflows, and helps surviving; Select to transplant a cutting, transplant a cutting and require healthy and strong, no damage by disease and insect, diameter 2cm is selected in specification requirement, the plugged ear of long 1~1.5m; Queensland bottle bar tree meat is loose, includes a large amount of moisture, and incision very easily is subjected to the infection of germ, and the plugged ear of cutting-out will be converted cement with carbendazim and seal, and through drying, uses after the wound cement for the treatment of two ends is received the universe under hidden environment; Cultivating container is selected dark tube plastic basin (degree of depth of basin is that 30cm, bore are 34cm), the plastic basin water retention property is better, cultivation matrix uses perlite portion, leaf mould portion, big two parts of river sands of grain, ash portion to convert water and stir, and the humidity of soil is as the criterion with the data that " suction type tensiometer " records; Plant after cultivating well must be placed under the sun-drenched environment, and bottle bar tree in Queensland's originates in Australia, and it is vigorous to grow in the environment of high-temperature drying, and its soil moisture of taking root is>50Kpa; Plant after cultivation is good is not watered immediately, and the humid air in the soil helps plant and bears new root system, waters once permeablely after 8~10 days again to plant, enters normal management later on; Can bear new root in 40-50 days, some root system can grow from the bottom outlet of cultivation tray after 80-90 days, can transplant; Through measuring, the seedling trunk position of cuttage after 2 years increases thick 8-9mm.
Advantage of the present invention: Queensland's bottle bar is set as outstanding ornamental tree species, in the china natural resources rareness, the breeding difficulty, the branch that the utilization of Queensland's bottle bar tree cuttage breeding method is pruned row is again bred, and has not only utilized resource but also solved the difficult problem of China Queensland bottle bar tree resource sleepiness.Shortened seedling raise period, moulding is fast, the rate of growing seedlings height, overcomes seed seedling long problem in vegetative period.
