Embodiment 1

[0028] Example 1

[0029] On May 16, 2018, choose a wisteria mother tree that has bloomed and is fruitful, and the trunk meter diameter is more than 2.5cm. On the trunk, select healthy, 1-year-old branches with a diameter of 0.5-1.0cm and no pests and diseases. For the smooth parts above 3 buds, use a sharp knife to cut up and down along the girdling part of the branch. Gently pick off the cortex from the side, and then use a cotton swab to dip the prepared 500mg / L naphthalene acetic acid aqueous solution to apply the girdling area 1 to 2 times, and let it dry for 5 to 6 minutes; finally use the cut square agricultural For the film, wrap the girdling mouth with pure yellow clay mixed with 500 mg / L naphthalene acetic acid aqueous solution to form an olive-shaped mud mass, and then tie the film at both ends tightly. In case of dry weather after branch stripping, water the roots of the mother tree once every 3 to 4 days. On June 19, 2018, 2 to 3 roots began to grow. On July 3, ...

Embodiment 2

[0031] On June 5, 2018, choose a wisteria mother tree that has bloomed and is fruitful, and the trunk meter diameter is more than 2.5cm. On the trunk, select healthy, 1-year-old branches with a diameter of 0.5-0.8cm and no pests and diseases. For the smooth parts above 3 buds, use a sharp knife to cut up and down along the girdling part of the branch. Gently pick off the cortex from the side, and then use a cotton swab to dip the prepared 500mg / L naphthalene acetic acid aqueous solution to apply the girdling area 1-2 times, let it dry for 5-6 minutes, and then use the cut square agricultural The film wraps the girdling mouth with pure yellow clay mixed with 800 mg / L naphthalene acetic acid aqueous solution to form an olive-shaped mud mass, and then the two ends of the film are tied tightly. In case of dry weather after branch stripping, water the roots of the mother tree once every 3 to 4 days. On July 9, 2018, it was observed that two roots began to grow. On July 16, many ro...

Embodiment 3

[0033] On July 18, 2018, choose a wisteria mother tree that has bloomed and is fruitful, and the main diameter is more than 2.5 cm. On the main trunk, select a robust, 1-year-old branch with a diameter of 0.5 to 0.8 cm and no damage from diseases and insect pests. For the smooth parts above 3 buds, use a sharp knife to cut up and down along the girdling part of the branch. Gently pick off the cortex from the side, and then use a cotton swab to dip the prepared 500mg / L naphthalene acetic acid aqueous solution to apply the girdling area 1-2 times, let it dry for 5-6 minutes, and then use the cut square agricultural The film wraps the girdling mouth with pure yellow clay mixed with 1000 mg / L naphthalene acetic acid aqueous solution to form an olive-shaped mud mass, and then the two ends of the film are tied tightly. In the rainy season after peeling off the branches, water the roots of the mother tree once every 3 to 4 days. On August 21, 2018, 2 to 3 roots began to grow. On the...

Abstract

The invention belongs to the technical field of asexual reproduction of plants, and in particular relates to a method for cultivating wisteria seedlings. The operation steps include layering in the air, management after stripping branches, transplanting of stripped branch seedlings, etc., selecting a flowering and fruiting mother tree with a trunk diameter of more than 2.5cm , The diameter of 0.5~1.0cm that germinates on the main branch of the plant is robust, and the 1-year-old side branch without diseases and insect pests is used as the stripping branch. The stripping seedlings with well-developed root systems are obtained by adopting the air layering method, and then the stripping seedlings are cut and transplanted into containers to cultivate wisteria seedlings. The invention cultivates wisteria seedlings with fast rooting at the girdling mouth, roots grow in 34 days, the seedling period is short, the root system of the seedlings is particularly strong and developed, the survival rate of transplanting can reach more than 91%, and the growth is rapid after transplanting, and it is ready after 3 months of cultivation. Can be out of the garden. The method is simple and easy to implement, has low cost, and better compensates for the problems of low rooting rate of wisteria hard branch cutting seedlings, small cutting seedlings, long flowering time of plants and the like. The invention can provide technical support for rapid cultivation of wisteria seedlings.

Description

technical field [0001] The invention belongs to the technical field of plant asexual reproduction, and in particular relates to a method for cultivating wisteria seedlings. Background technique [0002] Wisteria (Wisteria sinensis) is a liana of the genus Wisteria in the Fabaceae family. Wisteria has strong adaptability to climate, can withstand severe cold and heat, and can be planted in both north and south. It is a famous flower-viewing vine in my country. The inflorescences are large and long, with tens to hundreds of flowers in each sequence. The flowers are butterfly-shaped and purple-blue. They bloom from April to May every year. The strings of inflorescences are very cute and sway with the wind. The flowers are also edible. Residents in North China often use wisteria flowers mixed with sugar and flour to process them into wisteria cakes, which are flavored snacks. Wisteria has many advantages such as soft branches, fast growth, extensive management, eye-catching an...
