Problems solved by technology

The second is cutting seedlings: the survival rate of conventional hard branch cuttings is usually lower than 10%. Full-light semi-lignified tender branch cuttings require very high technology and full-light spraying systems and facilities. Usually, the survival rate is 40-50%. The cutting process A mistake in any link will cause the death of all the seedlings

Embodiment 1

[0028] Embodiment 1: a kind of efficient, rapid breeding method of European viburnum comprises the following steps:

[0029] A. Planting of Viburnum seedlings: Before the seedlings germinate in spring, purchase (or use conventional methods to breed 1-2 years old) European viburnum seedlings. The seedlings are required to be 20-40 (cm) high, with intact root systems and no pests and diseases. Seedlings. Apply basal fertilizer (2-4 tons / mu) and soil preparation (comprehensive soil preparation) according to conventional afforestation methods, and use border planting and border irrigation (planting seedlings can be large or small, according to the requirements of convenient management, you can choose 4 meters × 5 meters) method for afforestation , planting seedlings at a row spacing of 30-40×30-40 (cm), planting 7400-5550 seedlings per acre (calculated as 6000 plants per acre afterward), flat drying after planting, leaving a dry height of 5-8 (cm), and immediately irrigation;

Abstract

The invention relates to an efficient and rapid breeding method of viburnum opulus. According to the method, viburnum opulus nursery stocks are planted, environmental conditions suitable for rooting are provided at bud eyes of the viburnum opulus nursery stocks, so that adventitious roots can be generated at each bud eye of each branch of the viburnum opulus, branches with lignified adventitious roots are cut off after the adventitious roots are lignified, the cut-off branches are cut from internodes between the bud eyes to form cuttings with the adventitious roots and buds, root systems of the cuttings are completely embedded into soil, the bud eyes are covered, planting and culture are implemented, and each cutting can grow into a nursery stock. According to the biological characteristicof easy rooting at bud eyes of viburnum opulus branches, the cuttings with the roots and buds serving as intermediates of the nursery stocks are produced and cultured, the nursery stocks are culturedby the cuttings, and breeding efficiency is improved, so that the viburnum opulus is efficiently, simply and rapidly bred.

Description

technical field [0001] The invention relates to plant cultivation, in particular to a high-efficiency and rapid breeding method of the landscaping tree species Viburnum viburnum. Background technique [0002] It is the country's development strategy to fully implement the forestry development strategy focusing on ecological construction and to better play the five functions of forestry ecology, economy, society, carbon sinks and culture. In the near future, my country will complete 6 million hectares of new forests every year. Afforestation implements the national land ecological security barrier strategy, and the development direction of urban forestry is urban greening, beautification, dust reduction and noise reduction. [0003] With the development of China's social economy and the improvement of people's living standards, urban people have higher and higher requirements for the development of urban forestry, not only to increase the area of ​​green land, but also to have...
