Seedling cultivating method capable of shortening peach trees

Abstract

The invention relates to fruit tree seedling cultivating field, particularly discloses a seedling cultivating method capable of shortening peach trees. The method includes cultivating root stocks, dwarfed interstocks and scions. Main technology is characterized in that the root stocks adopt seedlings of wild peach seeds; the dwarfed interstock seedlings are hybrid seedlings obtained by using the wild peaches as female parents and white peaches as male parents, performing artificial interspecific hybridization, sowing seeds obtained from hybridization and allowing growing; and the step of cultivating the scions includes using the dwarfed interstocks as the scions, and grafting onto the root stocks (seedlings) to obtain short peach tree seedlings. according to the invention, the affinity of the root stocks and the scions is strong, the tree body is compact, the fruit bearing period is early, the yield is high; the short peach tree is good in cold resistance and disease resistance, easy in management, and suitable for urban and rural beautification, greening and potting.

Description

technical field [0001] The invention relates to the field of fruit tree seedling raising, more specifically, it relates to a seedling raising method for making peach trees dwarf. Background technique [0002] At present, in the seedling raising process of making peach trees dwarf, generally adopt arborization rootstock dwarf saplings, the method of raising seedlings of this dwarf pear tree is: at first cultivate seedlings after sowing with the seeds of wild mountain peach, as crop graft dwarfing The root stocks of peach trees are grafted on the root stock seedlings according to the procedure of grafting fruit trees, and then the dwarf peach trees selected in advance are grafted on the root stock seedlings as scions. Cultivate arborization stock dwarf sapling, its bottom is the seedling root stock, and the top is the scion of dwarfing, cultivates this dwarfing peach seedling, there are many drawbacks: [0003] (1) Peach trees are tall. With the growth of tree age, peach tree...

AI Technical Summary

Problems solved by technology

[0003] (1) Peach trees are tall, and with the growth of tree age, peach trees gradually grow taller, which is not convenient for management, and is not suitable for urban beautification, greening and potted plants;

[0004] (2) The phenomenon of large and small years is serious, and the size of fruit food is uneven, which affects the yield and is difficult to standardize;

[0005] (3) Fruit bearing is late, yield is low, and benefit is poor;

[0006] (4) There is a big difference between the root stock and the scion, showing incompatibility, low survival rate, no cold resistance, no resistance to diseases and insect pests
