Industrial seedling raising method for vine hard branch single-bud cuttage

Abstract

Disclosed is an industrial seedling culture method for a single-bud cutting of a grapevine hard branch. The method is completed in the following steps of: (1). collecting and storing seed branches; (2) cutting, dipping, disinfecting branches; paving galvanothermy root hotbed; preparing soil, making ridge and screening earth in plastic tent; (3) bagging cutting; (4) hardening and lifting plantlet. The invention has the advantages that: 1. seed branches are saved; 2. energy resource is saved and environment pollution is reduced; 3. the culturing speed is high; 4 earth and labor are saved; 5. planting survival rate is high; 6. the seedling culture, planting and success of garden construction in the same year can be realized, and 500-1000kg per 667 square meters can be realized in the second year; 7. the technology is simple, practical and suitable for being popularized.

Description

Technical field: [0001] The invention belongs to a seedling raising method, in particular to an industrial seedling raising method of grape hard branch single bud cuttings. Background technique: [0002] The common hardwood cutting seedling raising method currently used is mainly direct open-field cutting without rooting. [0003] 1. Preparation of nursery ground: Choose a place with flat terrain, loose and fertile soil, and irrigation conditions. In the autumn of the first year, the soil was deeply plowed by 30-40cm, and organic fertilizer was applied, and then winter irrigation. [0004] 2. Cuttings: After the soil is thawed in early spring, make a seedling bed. Generally, the bed is 1-1.2 meters wide and about 10 meters long. Cuttings are started when the local temperature is stable at 10°C (generally in mid-April in Tianjin). Soak the stored seed strips in clean water for 6-8 hours, and the cuttings are generally cut into about 20cm. Cutting plant spacing 12-15cm, row...

AI Technical Summary

Problems solved by technology

[0005] There are following defects in the above-mentioned seedling raising method: 1, the cutting survival rate is low, and the seedling quality is poor, and the seedling rate is generally only more than 60%; Generally only 6000-7000 cuttings / 667 square meters can be inserted in the open field

4. The seedling cultivation cycle is long and the cost is high. It takes one year to get out of the nursery, and it needs to be stored in winter, and planted in the spring of the second year. The garden is not slow and uneven
