A kind of method of kiwifruit finished seedling breeding

Abstract

The invention discloses a method for breeding kiwi fruit finished product seedlings in a greenhouse by using nutritive bowls. The method includes: seed collection, sandy storage, seedling heating bed laying, arc shed construction, sowing, seedling stage management, young seedling transplanting, nutritive bowl changing, and grafting. Seed selection can allow strong germination force of seeds, the emergence time is fast, the emergence rate and the evenness of the seedlings are better than that of variety seedlings, and the good seeds can ensure the whole quality of later seedlings; greenhouse nutritive bowl seedling cultivation can promote growth of the seedlings of the kiwi fruits during a seedling stage. The method is even in seedlings, is short in seedling cultivation period, is high in yield, is high in transplanting survival rate, is simple in technology, facilitates large-scale industrialized production, and has important practical significance for rapid large-scale seedling cultivation of the kiwi fruits.

Description

technical field [0001] The invention belongs to the technical field of agricultural seedling breeding, and relates to a method for breeding finished kiwi fruit seedlings. Background technique [0002] In recent years, my country's kiwifruit industry has developed rapidly. The average annual growth rate of new kiwifruit orchards is greater than 10%, and the demand for high-quality kiwifruit seedlings has increased sharply. At present, most fruit farmers in my country use seedlings to build gardens. Seedlings are grafted after 1-2 years of planting, fruit bearing begins in 3-4 years, and enters the full fruit period in 5-6 years. However, in foreign countries such as New Zealand, Italy, Chile, etc., most of the gardens are built with finished seedlings, which can bear fruit in 2-3 years, which is 2 years earlier than the traditional seedlings. [0003] According to the survey, there are many kiwifruit nurseries in my country with different scales and different technical appro...

AI Technical Summary

Problems solved by technology

There are many problems in raising seedlings in this way of raising seedlings: (1) The source of seeds is unknown, and some farmers or units use their own surplus or leftover fruits and rotten fruits accumulated in cold storage as seedlings for seedlings, resulting in the mixture of delicious and Chinese series, and the good and bad varieties. Make the seedlings uneven and the strains intricate

(2) The seedling period is long, and field nurseries usually sow seeds in mid-March, and grafting can only be carried out in the next year, which prolongs the seedling time, increases the blank period of investment, and prolongs the return period of funds

(3) Serious pests and diseases, field nurseries are prone to soil-borne diseases, root rot of seedlings, severe root-knot nematodes, weak seedlings and diseased seedlings cannot meet market demand

(4) The nursery rate is low, sowing in the field nursery is easy, but it is easy to cause uneven distribution of seedlings, high requirements for seedling management, difficulties in picking seedlings, weeding, etc., and the field is uncertain due to natural factors, resulting in a low nursery rate

(5) The root system is weak, transplanting is difficult and the survival rate is low. Traditional nurseries need to cut off the root system when transplanting out of the nursery, resulting in difficulty in transplanting and low survival rate
