Problems solved by technology

[0003] At present, the planting and cultivation of hybrid paulownia mainly adopts the traditional nursery seedling raising method to carry out real seedlings or root transplantation. The production cycle of seedlings is long and the land occupation is large, so it is difficult to realize efficient and rapid large-scale industrial planting and cultivation

Embodiment 1

[0033] A kind of hybrid paulownia seedling cultivating method of the present invention comprises the steps:

[0034] S1. Carry out aseptic bud culture: take hybrid paulownia paulownia tender stems or tender shoots as explants, first sterilize with 70-80% alcohol by volume ratio, then wash once with sterile water, and then adopt a mass fraction of 0.05-0.15 %HgCl 2 After the solution is sterilized, it is washed with sterile water for 3-5 times, and then cultured on a sterile bud culture medium, and the sterile buds are obtained after 16-18 days of cultivation.

[0035] The number of days of cultivation is mainly determined by the growth rate of the hybrid paulownia buds, and it is generally advisable for the aseptic buds to grow to about 1 cm. Of course, if the sterile sprout is longer than 1 centimeter (for example, grows to 1.5 centimeters) or shorter than 1 centimeter (for example, grows to 0.5 centimeters), it does not affect the realization of the purpose of the present i...

Embodiment 2

[0067] A kind of hybrid paulownia seedling cultivating method of the present invention comprises the steps:

[0068] S1. Carry out aseptic bud culture: take hybrid paulownia paulownia tender stems or tender shoots as explants, first immerse and disinfect in 75% alcohol by volume ratio, then wash once with sterile water, and then use 0.15% HgCl in mass fraction 2 After the solution is sterilized, it is washed with sterile water for 3-5 times, and then cultured on a sterile bud culture medium, and the sterile buds are obtained after 16-18 days of cultivation.

[0069] The number of days of cultivation is mainly determined by the growth rate of the hybrid paulownia buds, and it is generally advisable for the aseptic buds to grow to about 1 cm. Of course, if the sterile sprout is longer than 1 centimeter (for example, grows to 1.5 centimeters) or shorter than 1 centimeter (for example, grows to 0.5 centimeters), it does not affect the realization of the purpose of the present inve...

Embodiment 3

[0101] A kind of hybrid paulownia seedling cultivating method of the present invention comprises the steps:

[0102] S1, carry out aseptic bud culture:

[0103] Put the hybrid Paulownia that has just grown buds into a biochemical incubator, and after cultivating at 38-40°C for 6-8 days, cut the hybrid Paulownia buds and soak them in alcohol with a volume ratio of 70-80% for 1 minute to sterilize and mass ratio 0.05 -0.15% HgCl 2After the solution is sterilized, after washing with sterile water for 3-5 times, cut out the 1.8mm long bud tip and put it into the culture medium. Cultivate and repeat this for three or more times to obtain detoxified aseptic buds; because certain viruses can be killed after high-temperature cultivation, the conduction tissue at the growth point of the 2mm-long bud tip has not yet developed completely, which is not conducive to virus conduction, and a relatively high temperature can be obtained. Good virus-free aseptic buds, the advantage of such vi...

Abstract

The invention provides a cross-bred cultivation method for paulownia seedling. The steps include cultivating aseptic sprouts, using cross-bred paulownia tender shoot or bud as the outer stem, after disinfecting, sterilizing and cleaning, transplanting to a 1 / 2 MS or MS cultivation base with an appropriate amount of plant growth regulator added, cultivating for 12 - 18 days to have the aseptic sprouts; cultivating crowd shoots: cutting down the aseptic sprouts, transplanting to the MS crowd shoots cultivation base with an appropriate amount of plant growth regulator added; cultivating strong seedlings and developed roots: when the crowd roots grow to 1 - 2 cm, transplanting to the 1 / 2 MS and / or MS cultivation base with an appropriate amount of plant growth regulator added, cultivating with separate bottles, during the above steps, the cultivating temperature is between 15 - 30 DEG C, the light intensity is 2000 - 3000 LUX, the sunshine time is 6 - 12 hours per day; domesticating and transplanting; transplanting the reproduced plant from the roots to the base ground with garden soil and peat soil (2 : 1), using a shading net to shade from the light, keeping the dampness at 60 - 70%, 15 - 30 days after taking them out of the cultivation farm. This method greatly increases the growth speed and planting efficiency of cross-bred paulownia. The cost is low, and the pollution is reduced. The production can be at any season. The method is suitable for large-scaled seedling cultivations.

Description

technical field [0001] The invention relates to a method for cultivating hybrid paulownia seedlings. Background technique [0002] Paulownia is a plant of the genus Paulownia in the family Scrophulariaceae. It is widely distributed in my country and is the main fast-growing broad-leaved tree species. Paulownia grows very fast and matures early. There is a folk saying that "one year a pole, two years like an umbrella, and five years can saw a board". Hybrid Paulownia "9501" is one of the achievements of the 15 major scientific and technological research projects of the Paulownia Research Institute of the State Forestry Administration. Under favorable conditions, the 1-year-old tree grows up to 7-8 meters, and the ground diameter is more than 15-20 cm. It can be cut in rotation or in 3-4 years, and a single tree can reach 18 meters in 5 years. The diameter at breast height is more than 40 cm, the volume is 0.5-0.6 cubic meters, and the wood texture is straight, the pattern i...
