Embodiment 1

[0021] From 2012 to 2016, the technology of this invention was continuously used to breed plum and apricot seedlings. Rootstock seeds were prepared in 2012, sown in spring of 2012, grafted in February 2013, and so on, and tested for 4 consecutive years from 2013 to 2016. In November each year, 1000 seedlings were randomly selected by each of the two methods, and the root system, stem The dryness and other indicators are counted, and the cost is counted at the same time. The selling price is based on the market price. The production period is based on the first batch of seedlings in 2013 and after planting in November 2013. The specific statistical results are shown in Table 1 and Table 2.

[0022] As can be seen from Table 1 and Table 2, compared with the conventional seedling raising technology, the seedlings produced by the improved seed breeding technology of the present invention have a high survival rate and a nursery rate, fast propagation speed, well-developed plant root...

Abstract

The invention relates to a breeding technology of improved varieties, in particular to a breeding technology of improved varieties of plum and apricot seedlings. The improved varieties of seedlings are cultivated by the following steps: breeding field selection, pre-sowing treatment and germination cultivation, scion grafting, post-grafting treatment and seedling outplanting. The pre-sowing treatment is sand storage lamination. The breeding technology of improved varieties of plum and apricot seedlings provided by the invention has the advantages of disinfecting through pre-sowing treatment, preserving the good and rouging and preventing and controlling diseases and insect pests in germination cultivation and post-scion treatment, and ensuring no virus in seedling production; by raising seedlings in nutrition pockets, the root systems of young seedlings are all in the nutrition pockets, and the whole pockets with soil are transplanted while transplanting, so that the survival rate is improved, and the average survival rate is 96% or more; the main root number of the root systems of the seedlings obtained by breeding is at least five, the average length of main root and lateral root is at least 5cm greater than that of the conventional seedling breeding, the stem width is 0.8 to 1.2cm, and the full bud number of a training belt is more than 10. The plum and apricot seedlings bred by the invention have developed root systems, are robust and non-toxic, and have high survival rate and early production period.

Description

technical field [0001] The invention relates to the technical field of seedling breeding, in particular to a method for breeding plum and apricot seedlings. Background technique [0002] The breeding of improved seedlings is the continuation of the work of species selection and an important link in the application of improved seeds to production, which has very important significance and far-reaching influence. If good varieties are not frequently selected, and reasonable breeding techniques and breeding systems are not adopted, it will result in mixed varieties and degraded species, which will not only fail to meet the production requirements, but even bring serious adverse consequences to production. [0003] Plum and apricot are both stone fruit seedling varieties native to China, and their propagation is mainly through grafting. In recent years, the regional development of these two seedlings has been rapid, and the demand for seedlings has increased significantly. How...
