Problems solved by technology

[0002] Cherry, the fruit is gorgeous, high-quality, nutritious, known as the "treasure in the fruit", the fruit matures the earliest among the deciduous fruit trees in the north, and enjoys the reputation of "the first spring fruit". Its dormancy period is relatively short, and its cold resistance is weak. Low temperature is an important factor that limits the distribution and growth of plants. Especially in inland areas, the winter is long and cold, which makes cherries suffer from low temperature damage, often resulting in damage to flower buds and branches. In severe cases, the whole plant will die and cannot survive the winter safely; therefore, inventing a cherry with high cold resistance can effectively promote the rapid development and promotion of the cherry industry

Embodiment 1

[0019] In the embodiment of the present invention, a kind of hybrid seedling raising method that improves cold resistance of cherry, concrete method is as follows:

[0020] (1) Rootstock cultivation

[0021] At the beginning of March, cut the lignified branches of the 2-year-old Longbao cherry tree as rootstock cuttings. The cutting length is 17-19cm. Rootstock cuttings were immersed in the treatment solution for 44 minutes, drained and removed, cuttages were placed on the seedling substrate, and a mixed solution of 0.31% potassium dihydrogen phosphate aqueous solution and 0.43% urea aqueous solution was applied to the roots, and then every 25 Applied once every 27 days to obtain rootstock; the weight ratio of potassium dihydrogen phosphate aqueous solution and urea aqueous solution is 1:1.6;

[0022] (2) Cultivation of scions

[0023] At the beginning of March in the second year, cut the lignified branches of the 2-year-old Longdan cherry tree as the scion branch, cut the l...

Embodiment 2

[0031] In the embodiment of the present invention, a kind of hybrid seedling raising method that improves cold resistance of cherry, concrete method is as follows:

[0032] (1) Rootstock cultivation

[0033] At the beginning of March, cut the lignified branches of the 2-year-old Longbao cherry tree as rootstock cuttings. The cutting length is 17-19cm. Rootstock cuttings were immersed in the treatment solution for 46 minutes, drained and removed, cuttages were placed on the seedling substrate, and a mixed solution of 0.32% potassium dihydrogen phosphate aqueous solution and 0.44% urea aqueous solution was applied to the roots, and then every 25 Applied once every 27 days to get rootstock; the weight ratio of potassium dihydrogen phosphate aqueous solution and urea aqueous solution is 1:1.7;

[0034] (2) Cultivation of scions

[0035] At the beginning of March in the second year, cut the lignified branches of the 2-year-old Longdan cherry tree as the scion branch, cut the leng...

Embodiment 3

[0043] In the embodiment of the present invention, a kind of hybrid seedling raising method that improves cold resistance of cherry, concrete method is as follows:

[0044] (1) Rootstock cultivation

[0045] At the beginning of March, cut the lignified branches of the 2-year-old Longbao cherry tree as rootstock cuttings. The cutting length is 17-19cm. Rootstock cuttings were immersed in the treatment solution for 48 minutes, drained and removed, cuttages were placed on the seedling substrate, and a mixed solution of 0.33% potassium dihydrogen phosphate aqueous solution and 0.45% urea aqueous solution was applied to the roots, and then every 25 Applied once every 27 days to get rootstock; the weight ratio of potassium dihydrogen phosphate aqueous solution and urea aqueous solution is 1:1.8;

[0046] (2) Cultivation of scions

[0047] At the beginning of March of the second year, cut the lignified branches of the 2-year-old Longdan cherry tree as the scion branch, cut the leng...

Abstract

The invention belongs to the technical field of fruit culture and particularly relates to a hybrid seedling culture method capable of increasing cherry cold resistance. The method specifically includes the steps of firstly, culturing stocks; secondly, culturing scions; thirdly, grafting, and culturing after grafting. Hybrid seedlings obtained by the method have the advantages that membrane destroying and leakage under low temperature can be inhibited effectively, calcium ions are inhibited from entering cells, phospholipid degradation is lowered, cell membrane stability is protected, the balance between the generation and the elimination of free radicals in cherry trees is kept favorably, membrane lipid peroxidation can be avoided, relative intracellular environment stability is kept effectively, plasma membrane freezing injury degree is lowered, more moisture is retained, the probability of protoplasm injury and death caused by freezing is reduced, and cells and tissue are protected.
