Problems solved by technology

[0007] At present, the domestic use of the cuttings of golden leaf white wax shoots is the full-light mist cutting seedling cultivation system to control the cutting environment. This method has high costs and high environmental requirements, which is not conducive to market-oriented large-scale industrial production.

Embodiment 1

[0034] (1) Seedbed preparation: Build a steel structure arched greenhouse with a length of 20 meters, a width of 6 meters and a height of 3 meters, and cover it with a film. The top of the greenhouse is covered with a shading net with a shading rate of 75%, and reels are set on both sides. Roll up when the temperature is too high ventilation. The soil in the greenhouse was plowed deeply and carefully, and the soil was disinfected with 1% potassium permanganate solution. Make a seedbed with a width of 90 cm, a length of 18 m and a height of 20 cm after being leveled. Three seed beds are arranged in a greenhouse, and the distance between the seed beds is 45-50 cm. Use three layers of ordinary sintered bricks to build side fences around, and ensure that there is a 10cm height difference from the seedbed, so that 3cm of medium-coarse sand with a fineness modulus of 3.7-1.6 can be spread on the seedbed, and the seedbed will be watered thoroughly to avoid It is advisable to infiltr...

Embodiment 2

[0053] In the intelligent temperature-controlled greenhouse of the high-voltage electrostatic electromagnetic nursery area of ​​Hefei Forestry High-Tech Center and Hefei Forestry Science and Technology Demonstration Park, the size of the seedbed is 6.0m×1.2m×0.4m. For the convenience of operation and drainage of the seedbed, the center of the seedbed is higher than the sides 2cm, leaving drainage holes at the bottom. The seedbed is tiled with 10cm thick perlite, and in the intelligent temperature-controlled greenhouse: through the simulated leaf sensor every day, when the air humidity is less than 80%, the automatic spraying is controlled by the computer. The weather adopts the principle of "a small amount and many times", maintain a relative humidity of 90-91%, and a temperature of 30°C-40°C. Other conditions are the same as in Example 1, and after culturing for 30 days as in Example 1, the results are shown in Table 5.

Abstract

The invention discloses a gold leaf twig cutting seedling method. The method is characterized by comprises the steps of cutting bed preparation, cutting stem selection, cutting shoot making, cutting shoot hormone rooting induction, cutting, post-cutting management and the like. Perlite is used as a substrate of a cutting bed, and the cutting stem selection time is May, June and July; cutting stems with the diameter ranging from 4 mm to 6 mm are selected as cutting shoots and disinfected, and then the bottoms of the cutting shoots are soaked in a growth regulating agent of 50 ppm to 800 ppm for 1 min to 2 h; a straight cutting method is adopted for cutting the cutting shoots into the seedbed, and a small arched shed is built after cutting; the small arched shed is covered with a film and sealed, the seedbed is watered thoroughly at a time before sealing, the temperature inside the small arched shed is kept to range from 30 DEG C to 40 DEG C, and the humidity is kept more than 90%; water addition or film removing and ventilation is not needed within one month; the cutting environment most suitable for growth of gold leaf twigs is obtained through screening by adjusting and controlling cutting shoot obtaining time, the cutting environment, the cutting shoot selection, the cutting substrate selection, the selection of hormone promoting rooting and other aspects, and theoretical and technical bases are provided for obtaining a large number of excellent clonal plants which are capable of being developed and achieving production and utilization, high in genetic gain and uniform in character.

Description

Technical field: [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to the cutting technology of twigs of golden leaf white wax. Background technique: [0002] Golden leaf white wax, also known as golden crown white wax, (Fraxinus Linn) Oleaceae Ash, is a cultivated variety of European white wax, deciduous tree, dense branches and leaves, beautiful tree shape, and golden leaves in three seasons, 10-15 meters high, light bark tan. Branchlets smooth and glabrous; leaflets 5-9, ovate-elliptic, apex acuminate, base narrow, asymmetrical, margin toothed and wavy, surface glabrous; calyx campanulate, petalless; flowering period March-May. In spring, the small buds first sprout, like the golden wintersweet branches blooming all over the tree, and after the leaves are unfolded, the whole crown of the tree seems to be full of gold ingots. All the leaves are golden yellow before the end of July, and then the young leaves are...
