Cuttage seedling culture method of liquidambar styraciflua

Abstract

The invention belongs to the technical field of seedling breeding, and relates to a cuttage seedling culture method of liquidambar styraciflua. According to the method, parent semi-lignified current-year branches are selected to be sheared into cuttage branches with the length being 8 to 10cm, 2 to 3 buds and 2 to 4 leaves are reserved, the upper ends of the cuttage branches are flatly sheared, the shearing position is 1 to 1.5cm from the upper part buds, the lower part is sheared in the inclined direction, the shearing openings are flat and smooth, the cuttage branches are placed into a nutrition solution to be soaked for 1 to 2 hours and are then inserted into a mixed substrate of perlite and turfy soil subjected to sterilization treatment, and the bare-root transplanting can be carried out after the culture for 40 to 45 days in the mixed substrate of the perlite and the turfy soil. The cuttage substrate adopts the mixed substrate formed by the perlite and the turfy soil according to the weight ratio being 5:1, the ventilation performance and the moisture absorption performance are good, the cost is low, the conditions are favorable for root system growth, and the rooting rate is high; a soaking process is adopted, and cutting slips are soaked for 1 to 2 hours in the nutrition solution, so that the roots of the cutting slips have the sufficient time to absorb nutrients in the nutrition solution, then, the cutting slips are subjected to cuttage into the prepared mixed substrate, root nodules are formed after 5 to 7 days, the rooting is realized after 13 to 15 days, the bare-root transplanting can be carried out after 40 to 45 days, the root system is developed, the survival rate is high, and can reach more than 95 percent, and the seedling forming period is short.

Description

technical field [0001] The invention relates to a plant breeding technology, which belongs to the technical field of nursery stock breeding, and in particular relates to a cutting seedling raising method of American red maple. Background technique [0002] American red maple (scientific name: Acer rubrum L.): native to the east coast of the United States, mainly from the northern United States and most of Canada. It is a large deciduous tree with fast growth. The adult height is 12-18 meters, and the crown width is 12 meters. , can adapt to the growth of various soil types, blooms in spring, and the flowers are red. Because of its eye-catching colors in autumn and neat tree crown, it is widely used in parks, residential areas, and streets for planting. It can be used for landscaping and street trees. It is deeply loved by people. It is an ideal rare for landscaping and greening urban gardens introduced in recent years. One of the tree species and the only color-leaved tree ...

Problems solved by technology

This method also adopts the rapid dipping process, the time is relatively short, the absorption of nutrient solution is less, the nutritional effect cannot be achieved, and the nutrient solution will flow down to the bottom of the cuttings, which can only promote the production of the bottom root, making the overall root system not strong enough. Although its rooting rate is high, and the survival rate reaches more than 95%, its rooting speed is relatively slow, and the seedling cultivation period is long.
