Suspension type strawberry germplasm resource preservation method

Abstract

The invention discloses a suspension type strawberry germplasm resource preservation method. Seedling substrate soil is adopted, a bio-organic fertilizer is added, the adding amount of the bio-organicfertilizer accounts for 5% of the volume of the seedling substrate soil, and the seedling substrate soil and the bio-organic fertilizer are uniformly mixed to obtain a seedling substrate; a seedlingpot is fully filled with the seedling substrate, and thorough watering is carried out; healthy and disease-free strawberry plants are selected, and the specification of seedlings is that 10 nutritionpot seedlings which are 1.0 cm in rhizome thickness, short, strong, solid and free of plant diseases and insect pests are selected; roots are dipped with a medicament before planting, and transplanting is carried out after root dipping of plants; during planting, no core is buried at the upper part, no root is exposed at the lower part, then the seedling pot is placed into a fixing ring of a suspension device, watering for 1-2 times every day is carried out within 7 days after field planting, local moisture of rhizomes and root systems is kept, and germination of new roots is promoted; and strawberry stock plants are preserved through the suspension type strawberry germplasm resource preservation method, the continuous cropping problem and the disease infection problem caused by open-fieldcultivation of the stock plants are solved, the germplasm resource mixing problem is effectively solved, and meanwhile space can be effectively utilized.

Description

technical field [0001] The invention relates to a hanging method for preserving strawberry germplasm resources, which belongs to the field of agricultural planting. Background technique [0002] The preservation of strawberry germplasm resources is the premise and foundation of strawberry breeding. At present, the preservation of strawberry germplasm resources mainly includes three methods: field cultivation, seedbed matrix potting and tissue culture explant preservation, among which field cultivation and seedbed matrix potting are the most common, usually choose a Variety resource nursery, paving the ground, and then planting strawberry seedlings in flowerpots, 4-6 pots for each variety, placed according to the area of ​​​​variety resources, the distance between pots of the same variety is generally about 5cm, between varieties The distance between pots is generally 10-15cm, and then the conventional germplasm resource preservation and management are carried out. However, d...

AI Technical Summary

Problems solved by technology

It mainly solves the problems of cumbersome storage, utilization and management of conventional strawberry germplasm resources, which can easily lead to mixed germplasm, cross-infection of diseases, serious soil-borne diseases, etc.
