specific Embodiment approach 1

[0037] Specific implementation mode 1: This implementation mode is within the area from 44 degrees north latitude to 50 degrees north latitude ， With the cold-resistant kiwifruit seedlings in the open field as the rootstock, and the adult trees in the production garden as the scion source, the kiwifruit seedlings are cultivated for open field cultivation, and the specific method is carried out in the following steps:

[0038] Step 1. Collect the mature fruit of kiwifruit in the open field, then take out the seeds, dry them, and store them in a shaded and dry place at 0-5°C;

[0039] Step 2. At the beginning of January next year, immerse the seeds obtained in step 1 with water at 30-40°C for 1 day, then put them into gauze bags and bury them in sand, and freeze them at -5-15°C for 60-70 1 day, then slowly thawed at 0-5°C, and then germinated at 18-20°C until the seed coat cracked, white radicles were seen, and germinated seeds were obtained;

[0040] Step 3. Then in the sol...

specific Embodiment approach 2

[0050] Specific implementation mode two: In this embodiment, the seedlings of Chinese kiwifruit and delicious kiwifruit cold-resistant varieties are used as rootstocks, and the new shoots of adult trees from Chinese or delicious cold-resistant varieties are used as scions to carry out cold area protected areas (greenhouses and plastics). The general name of greenhouse) kiwifruit seedling cultivation for cultivation, the specific method is carried out according to the following steps:

[0051] Step a, collect mature fruits of Chinese kiwifruit or delicious kiwifruit varieties, then take out the seeds, dry them, and store them in a shaded and dry place at 0-5°C;

[0052] Step b. At the beginning of January next year, immerse the seeds obtained in Step 1 in water at 30-40°C for 1 day, then put them into gauze bags and bury them in sand, and freeze them at -5-15°C for 60-70 1 day, and then slowly thawed at 0-5°C, and then germinated at 18-20°C until the seed coat cracked and w...

specific Embodiment approach 3

[0062] Specific implementation mode 3: This implementation mode is a specific implementation mode of transfer breeding of germplasm resources.

[0063] Wild soft jujube, dog jujube and Gezao are precious kiwifruit resources in Heilongjiang Province, with rich genetic diversity. Some populations are still in the original state, and some have disappeared. The improper logging and development of forest resources in the past 60 years has exacerbated the demise of this wild fruit tree resource, and it has become an endangered plant. In order to effectively protect and utilize this natural precious resource, research work such as molecular markers, fruit proteomics, in situ dynamic investigation, protection of heterotopic germplasm gardens and natural hybridization variant population cultivation has been carried out. The kiwifruit seedling cultivation method provided by the present invention simultaneously As a new use for transferring inoculum resources, returning to the mounta...

Abstract

The invention relates to a kiwi seedling cultivation method, belongs to the technical field of kiwi cultivation, and solves the problems that the existing kiwi seedling cultivation technique fails to meet the needs of standard production, large-scale gardening, germplasm resources transferring and conservation, and planting in protected areas due to the factors such as long seedling cultivation period, low seedling emergence rate, few seed sources and slow cultivation. The method includes using of greenhouses, trays, plastic-covered tunnels and plastic film mulching; cold storage, stratification, sowing, stock cultivation, branch grafting, field management and outplanting of stock seeds. The whole cultivation process starts from January and ends before soil freezing in November and is under quality control. According to the method, seeding, grafting and outplanting all occur in one year. The time from storing seeds in sand to emergence of seedlings lasts for 11 months, namely the seedling cultivation time is 11 months, the rate of first-grade seedlings is up to 90%, and the need of standard, large-scale planting and demonstrative popularization of kiwi and the need of germplasm resources expansion and protection are met.

Description

technical field [0001] The invention belongs to the technical field of kiwifruit cultivation and specifically discloses a method for cultivating kiwifruit seedlings. Background technique [0002] The ancestor of kiwi fruit originated from my country, and was utilized by New Zealand, European and American countries, and developed into a worldwide fruit. Long-term competition has occupied the international kiwi fruit market. my country has experienced 30 years of investigation, excavation, domestication, improvement, selection and breeding of kiwifruit resources to the rise of the industry. New Zealand has obtained resources from my country, leading the world, and has become a major country in kiwifruit breeding, production and export for 100 years. , Japan is also 40 years ahead of my country. It is an important link to speed up my country's becoming a powerful country in kiwifruit resources and cultivation, and to study and solve technical problems in seedling cultivation. ...
