Problems solved by technology

Although foreign GF677 tissue culture and rapid propagation technology is relatively mature, due to commercial reasons, there are few written reports on its proliferation, rooting medium formulations and transplanting procedures.
At present, there is no relatively mature tissue culture and rapid propagation technology in China for the large-scale production of this rootstock

Embodiment 1

[0065] In Chengdu area in 2016, 50g of boron fertilizer with 20% pure boron content was applied to each root of GF677 in late March, 200g of 50% potassium sulfate was applied to each root of each plant in early May, and 0.2% borax and 0.3% dihydrogen phosphate were sprayed on leaves in early June Potassium three times, 15 days apart.

[0066] In the last ten days of September, from a healthy growing tree without pests and diseases, collect semi-lignified branches of the year with full buds in the middle and upper parts of the canopy, with a thickness of 1.0 cm. Cut off the top and base of the branches, and leave the middle and upper parts as cuttings. For short branches with a length of 16cm, 3-5 full buds are left for each cutting. The lower 5-8cm leaves are removed, and the upper 3-5cm leaves are kept. The base of the cuttings is immersed in water, and the upper part is covered with a sunshade net, and placed in a cool place for later use. Before cutting, soak the base 3cm ...

Embodiment 2

[0071] In Meishan area in 2017, 50g of boron fertilizer with 20% pure boron content was applied to each root of GF677 in late March, 200g of 50% potassium sulfate was applied to each root of each plant in early May, and 0.2% borax and 0.3% dihydrogen phosphate were sprayed on leaves in early June Potassium three times, 15 days apart.

[0072] In the second ten days of the month, collect the semi-lignified branches of the year with full buds in the middle and upper parts of the canopy from the fruit trees that are healthy and free from diseases and insect pests. The thickness is 1.0 cm. Cut off the top and base of the branches, and leave the middle and upper parts as cuttings. For shorter branches, 3-5 full buds are left for each cutting, the lower 5-8cm leaves are removed, and the upper 3-5cm leaves are kept, cut flat at a distance of 1-1.2cm from the upper buds, and the lower ends are cut into oblique planes. The base of the cuttings is immersed in water, and the upper part i...

Abstract

The invention discloses a high-efficiency cutting propagation method for plum and apricot stocks. The method comprises the following steps: S1, carrying out management of seed tree for branches taking; S2, carrying out cutting; S3, carrying out cutting slip collection and trimming; S4, carrying out cutting slip processing; S5, carrying out seedbed cutting; S6, carrying out post-cutting management;and S7, carrying out hardening-seedling transplanting. The method has the following beneficial effects: the seedling growing period is short; the hereditary features are stable; the technical equipment is simple; the breeding coefficient is high; and the needed cost is low.

Description

technical field [0001] The invention relates to a high-efficiency cutting propagation method for plum and apricot rootstocks. Background technique [0002] The economic life span of plum trees and apricot trees is generally 15-20 years, compared with other fruit trees, the economic life span is relatively short. Since the reform and opening up, my country's plum and apricot production has experienced years of steady and rapid development. In many areas, the plum and apricot industry has become the main economic pillar for rural industrial structure adjustment and farmers' income increase. my country's plum and apricot rootstocks have always used raw peaches, mountain peaches, etc., and these rootstocks have poor resistance. In order to maintain the dominant position of the industry under the condition of limited land, there is a trend of frequent transformation of old orchards and renewal of old varieties, and problems such as obstacles to replanting in production have beco...
