Problems solved by technology

Shandong Provincial Academy of Forestry and Luoyang Forestry Institute have used artificial hybridization technology and multi-level breeding technology based on ecological concepts to breed new varieties with characteristics that expand their uses, such as the fast-growing catalpa tree "Rosalpa 1" and "Rosalpa 2". ", timber tree species "1-4", ornamental tree species "Zhaoxia", etc., the market utilization rate has increased, but the reproductive coefficient of fine varieties is low, and the gap is large
[0003] After years of research, it has been found that catalpa can be propagated by cuttings, grafting and other methods. The survival rate of catalpa cuttings is extremely low, especially that of hard branch cuttings. When cultivating catalpa by grafting, the selection of grafted rootstocks is low and the utilization rate is low. , and the grafting time is greatly affected by climate, temperature and humidity

Embodiment 1

[0023] A method for quickly cultivating catalpa by grafting and cutting, the steps are:

[0024] 1) In spring, select the hard branches of catalpa tree (second year branches) with a diameter of 1-1.5cm, which are healthy and free from diseases and insect pests, as the rootstock for catalpa grafting. The mixture of carbendazim and aluminum triethylphosphonate (the mixture of carbendazim and aluminum triethylphosphonate is a 400-fold dilution of 25% carbendazim and a 200-fold dilution of 40% aluminum triethylphosphonate, according to the mass ratio 1:1 mixture);

[0025] 2) Take catalpa scion (the scion retains a plump upper bud, and the thickness of the xylem of the scion is 0.8-1 cm) and sterilize it in chlorothalonil. After washing with water, soak it in 300PPM 6-benzylaminopurine aqueous solution for 2 hours. Carry out catalpa grafting on the hard branch of catalpa by bud grafting (the grafting point is 5cm away from the upper end of the hard branch of catalpa). After the i...

Embodiment 2

[0030] A method for quickly cultivating catalpa by grafting and cutting, the steps are:

[0031] 1) In autumn, select hard branches of catalpa tree (second-year branches) with a diameter of 1.5-2mm in diameter, free from diseases and insect pests, as catalpa grafting rootstocks, trim them into 10-15cm sections, cut the upper end flat, and cut the lower end smoothly and obliquely, and spray multi-bacteria The mixed solution of carbendazim and aluminum triethylphosphonate (the mixed solution of carbendazim and aluminum triethylphosphonate is a 400-fold dilution of 25% carbendazim and a 200-fold dilution of 40% aluminum triethylphosphonate, according to the mass ratio of 1 :1 mixture);

[0032] 2) Sterilize the scion of catalpa (one plump upper bud on the scion, and the thickness of the xylem of the scion is 0.8-1 cm) in chlorothalonil, wash with water, soak in 200PPM 6-benzylaminopurine aqueous solution for 3 hours, and use xylem Carry out catalpa grafting on the hard branch of...

Abstract

The invention relates to a rapid catalpa bungei cultivating method integrating grafting and cuttage. Catalpa ovata branches serve as stocks for heteroplastic grafting, cuttage is performed for seedling raising after catalpa bungei with xylems undergoes bud grafting. The rapid catalpa bungei cultivating method integrating grafting and cuttage is simple in operation, the stock utilization rate is high, the grafting and cuttage are not influenced by time, weather, environment, temperature and the like, the cuttage rotting rate is up to 100%, and the survival rate is up to 98% or above. The problems of slow catalpa bungei seedling breeding, short grafting period, low preserving rate after conventional grafting, long adult seedling cultivating time, low stock commodity and the like are solved, and accordingly the demand for a large number of fine catalpa bungei varieties, stocks and adult seedlings in the market. The seedling raising period can be shortened to be one year by adopting the method, the seedlings are orderly in height, the production cost is greatly reduced, the seedling raising speed is improved, factorized catalpa bungei production is achieved, and the economical benefit is remarkable.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a rapid cultivation method of catalpa by grafting and cutting. Background technique [0002] Catalpa belongs to Bignoniaceae catalpa, is a national reserve forest tree species, with wide distribution, good wood quality, beautiful tree shape, large leaves, and great ornamental value in flowering period. Catalpa is known as "both material and appearance". One of the precious native tree species. Shandong Provincial Academy of Forestry and Luoyang Forestry Institute have used artificial hybridization technology and multi-level breeding technology based on ecological concepts to breed new varieties with characteristics that expand their uses, such as the fast-growing catalpa tree "Rosalpa 1" and "Rosalpa 2". ", timber species "1-4", ornamental tree species "Zhaoxia", etc., the market utilization rate has increased, but the reproductive coefficient of fine varieties is low, and the ...
