Problems solved by technology

[0004] However, at present, most of these sterling resources are wild or semi-wild seedling populations, and there are not many large-scale commercial cultivations. Most of the seedling breeding methods are traditional seeding and cutting propagation methods. There are large differences between plants in seeding propagation, especially The sowing and germination rate of sycamore is very low, so far there has been no artificial introduction and cultivation; cutting propagation requires a large amount of propagation materials, and it is difficult to breed a large number of high-quality seedlings in a short period of time, which is not conducive to the promotion of improved breeding. Grafting is prone to "watering" phenomenon, which seriously affects the survival rate of grafting, thus limiting the large-scale cultivation of sterling plants

Embodiment 1

[0042] A method for grafting and cultivating seedlings of Sterula, comprising the steps of:

[0043] (1) Seed treatment: select Pingpo seeds without mildew and no damage by diseases and insect pests, soak for 4 minutes with 900 times of 70% wettable powder thiophanate-methyl solution before sowing, and remove stunted and unfulfilled seeds floating on the water surface. Seeds, finally take out the seeds and put them in a cool and ventilated place to dry for later use;

[0044] (2) Rootstock cultivation: mix the sieved sandy loam, rice husk, and decomposed cake fertilizer in a ratio of 7:1:3 to prepare a seedling-raising substrate, apply 58 grams of 65% Zinc powder to the seedling-raising substrate, stir and mix well Cover with a film for 3 days and then remove the film and bag it. Before sowing, the matrix is ​​sprayed with aerosol to keep the humidity in the matrix at 60%. The treated seeds are sown in a nutrient bag equipped with a seedling-raising matrix. The surface of the...

[0052] A method for grafting and cultivating seedlings of Sterula, comprising the steps of:

[0053] (1) Seed treatment: select Pingpo seeds without mildew and no damage by diseases and insect pests, soak for 3 minutes with 800 times of 70% wettable powder thiophanate-methyl solution before sowing, and remove stunted and unfulfilled seeds floating on the water surface. Seeds, finally take out the seeds and put them in a cool and ventilated place to dry for later use;

[0054] (2) Rootstock cultivation: Mix sieved sandy loam, rice husk, and decomposed cake fertilizer in a ratio of 5:1:3 to prepare a seedling-raising substrate, apply 55 grams of 65% Zinc powder to the seedling-raising substrate, and mix well Cover with a film for 2 days and then remove the film and bag it. Before sowing, the matrix is ​​sprayed with aerosol to keep the humidity in the matrix at 50%. The treated seeds are sown in a nutrient bag equipped with a seedling matrix. Dig out a seeding hole with a depth...

Embodiment 3

[0062] A method for grafting and cultivating seedlings of Sterula, comprising the steps of:

[0063] (1) Seed treatment: select Pingpo seeds without mildew and no damage by diseases and insect pests, soak for 5 minutes with 1000 times of 70% wettable powder thiophanate-methyl solution before sowing, and remove stunted and unfulfilled seeds floating on the water surface. Seeds, finally take out the seeds and put them in a cool and ventilated place to dry for later use;

[0064] (2) Rootstock cultivation: mix the sieved sandy loam, rice husk, and decomposed cake fertilizer in a ratio of 8:2:4 to prepare a seedling-raising substrate, apply 60 grams of 65% Zinc powder to the seedling-raising substrate, stir and mix well Cover with a film for 3 days and then remove the film and bag it. Before sowing, the matrix is ​​sprayed with aerosol, and the humidity in the matrix is ​​kept at 70%. The treated seeds are sown in a nutrient bag equipped with a seedling-raising matrix.

Abstract

The invention discloses a grafting and seedling raising method for sterculia nobilis plants, and belongs to the technical field of planting of sterculia nobilis plants. The method comprises the following steps of, (1), seed treatment; (2) rootstock culture; (3) rootstock preparation; (4) scion treatment; (5) grafting; (6) planting; and (7) management. According to the method, sterculia nobilis seeds are treated with thiophanate methyl fluid before being sown, the seeds germinate to reach the stem thickness of 0.9-1.5 cm to serve as rootstock, annual semi-lignified twigs serve as scions, and the scions are treated with an activating solution composition before grafting, so that division and differentiation capacity of cells at incisions can be promoted, the healing capacity of the incisionsis improved, the healing time is shortened, growth of the scions is promoted, the budding rate of the scions is increased, and the grafting survival rate is further increased; and after the grafted seedlings survive, the seedlings are lifted out of nursery for planting, so that the breeding time of the high-quality seedlings is greatly shortened, and the breeding efficiency and the market competitiveness are improved.

Description

technical field [0001] The invention belongs to the technical field of plant grafting and planting, and in particular relates to a method for grafting and raising seedlings of Sterula plants. Background technique [0002] Grafting is one of the artificial propagation methods that are often used in agricultural planting. It refers to the technology of transferring the buds and branches of a good variety of plants to the stems and roots of another plant, and allowing them to heal to form new independent plants. , is a technique widely used in the seedling raising and production process of horticultural crops. The important factor affecting the grafting result is the "affinity" between the scion and rootstock of both grafting parties. The affinity here refers to the "affinity" between the grafting parties. The distance of the genetic relationship between the two, whether the internal organizational structure, physiology and genetics of the two are similar, that is to say, the c...
