Embodiment 1

[0024] In mid-June 2015, in Nanchang City, Jiangxi Province, a total of 10,356 cuttings were cut and 9,528 survived. The method is to prepare the site according to the ridge width of 1m and remove weeds one day before the cutting, and fragment the soil about 10cm above the surface. According to the ratio of 1:1, mix the natural soil and humus soil evenly to get the mixed soil, spread it evenly on the crushed soil, the depth is about 3cm, and disinfect it with a 1000 times solution of potassium permanganate. The cuttings are carried out in the evening of cloudy or sunny days, and semi-lignified branches of young trees that grow vigorously and have no diseases in that year are selected. Cut the spikes to be 10-15cm long, and the base is about 2cm below the axillary buds, remove the young leaves, keep 2-3 axillary buds, and leave 2-3 leaves (cut off 1 / 2 area). Immediately after the cuttings are cut, the incisions are aligned and tied tightly, and the lower end 3-5cm of the branc...

Abstract

The invention belongs to the field of plant breeding, and particularly relates to a method for increasing cutting survival rate of liriodendron sino-americanum. The method mainly comprises the following steps of selecting cutting substrates of the liriodendron sino-americanum and selecting cutting slips; selecting a formula of a rooting agent, a leaching manner, and a disinfection technique; and taking moisture preservation and temperature adjustment and control measures. According to the method disclosed by the invention, the problems that the cutting scion bases of the liriodendron sino-americanum are easy to rot and the rooting rate is low are solved, the cutting survival rate is increased to 92%, and the cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of plant breeding, in particular to a method for improving the survival rate of cuttages of japonica japonica. Background technique [0002] Asian-American mandarin tree, also known as hybrid mandarin wood or hybrid tulipwood, is a famous tree breeder in my country and the late Professor Ye Peizhong of Nanjing Forestry University. A new tree species bred by artificial hybridization of Mandarin japonica. In the past, it was commonly known as hybrid mandarin tree or hybrid tulipwood (Liriodendron chinense (Hemsl.) Sarg. × L. tulipifera L.). Because this tree species has its unique morphological characteristics and biological characteristics, it is an independent species, and it was renamed as Liriodendron sino-americanum P.C. Yieh ex Shang et Z.R.Wang). Yamei mandarin wood not only has the advantages of fast growth, strong resistance, and good material, but also has beautiful tree shape and bright colors. It is an exc...
