Problems solved by technology

[0003] Moreover, the 2-year-old seedlings are full and exposed, and they are easy to be damaged and fall off during the process of raising seedlings, bundling, and transportation. There are no buds at the positions where branches need to be sprouted, making it difficult to shape the tree. At the same time, it affects the reproductive rate of sweet cherries and indirectly affects the economy. benefit

Embodiment 1

[0031] A kind of quick cultivation method of sweet cherry grafted seedling, comprises the steps:

[0032] 1. Scion collection and preservation:

[0033] The scion variety is 'Pioneer'. After the leaves of the tree dormant, select robust plants, collect 1-year-old branches with full buds, arrange them into bundles, hang labels, wrap them with 3 layers of safe plastic film, and put them in a -1°C freezer Stored and grafted at the end of May of the following year for later use;

[0034] 2. Cutting propagation of rootstock:

[0035] (1) collection of cuttings: the rootstock variety is "Gisela No. 6", and in June every year, in the healthy, detoxified rootstock ear picking nursery through tissue culture, cut the new-born rootstock fringes of 10cm in length in that year. Remove base leaves and 2cm higher lignified parts, cut the bottom of branches obliquely at 40°, make the base in a semi-lignified state, make the lower cut close to the axillary buds, and keep 2 leaves at the top;...

Embodiment 2

[0047] A kind of quick cultivation method of sweet cherry grafted seedling, comprises the steps:

[0048] 1. Scion collection and storage:

[0049] The scion variety is 'Pioneer'. After the leaves of the tree dormant, select robust plants, collect 1-year-old branches with full and full buds, organize them into bundles, hang labels, wrap them with 4 layers of safety plastic film, and put them in a -4 ℃ cold storage Stored and grafted at the end of May of the following year for later use;

[0050] 2. Cutting propagation of rootstock:

[0051] (1) collection of cuttings: the rootstock variety is "Gisela No. 6", in July every year, in the healthy, detoxified rootstock ear nursery through tissue culture, cut the new-born rootstock fringe of 14cm in length in that year, cut Remove base leaves and 3cm higher lignified parts, cut the bottom of branches obliquely at 45°, make the base in a semi-lignified state, make the lower cut close to the axillary buds, and keep 3 leaves at the t...

Abstract

The invention relates to a quick cultivation method of grafted sweet cherry seedlings and belongs to the field of plant cultivation. The method comprises steps as follows: collection and storage of variety scions; preparation of a cutting bed, cuttage and management after cuttage of rootstock, grafting of the scions and management of nursery stock after grafting. A greenhouse is adopted for special cultivation, grafting of the variety scions is performed in the second half of May, transplantation can be performed in the very year after leaf falling, the seedling raising time is greatly shortened, and the grafted sweet cherry seedlings are obtained quickly. With the adoption of the method, sweet cherries only take one growth season from rootstock seedlings to transplantation of the grafted variety scions, and cultivation time of the grafted sweet cherry seedlings is 1 year shorter than that of the seedlings cultivated with a conventional seedling raising method. The nursery stock can be transplanted after leaf falling in the early winter, the seedlings are 1.5-2.0 m high, the base of each seedling is 1.0-1.5 m thick, sprouts are plump, the germination rate is high, and the nursery stock is high in quality and strong. The seedling raising cost is greatly reduced due to the fact that the seedling raising time is shortened by 1 year.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a method for quickly cultivating sweet cherry grafted seedlings. Background technique [0002] The breeding of sweet cherry seedlings includes the cultivation of rootstock seedlings, grafting of scion varieties, management of grafted seedlings, and several stages of nursery emergence. Rootstock seedling propagation is divided into seed propagation, root tiller seedling layering propagation, tissue culture and twig (or hard branch) cutting propagation. It takes 1 year for rootstock seedlings to reach grafting thickness for seed and layering propagation, and tissue culture or twig cutting propagation for rootstock It takes 1-2 years for seedlings to reach the grafting thickness; grafting of scion varieties is mostly in autumn (early September) and spring (March) of the following year, and it takes 1 year for grafted seedlings to grow out of the nursery. In this way, con...
