One-film double-greenhouse seed seedling culture method for wild alpine roses

Abstract

The invention relates to a seedling culture method, in particular to a one-film double-greenhouse seed seedling culture method for wild alpine roses.A thin film is firstly laid in a built nursery pond, a seedling culture substrate is laid on the thin film, the nursery pond is built in a greenhouse, and a small shed is constructed on the nursery pond.According to the method, soilborne diseases can be effectively prevented, germination of weeds on the ground is effectively prevented, meanwhile, water seepage can be prevented, and an ideal moisture preservation effect is achieved.A double-greenhouse structure can effectively carry out heat preservation and moisture preservation, and it is avoided that condensation water drops on greenhouse roofs scour and damage seeds.The seedling culture method is easy to operate, the requirement for the conditions of facilities is not high, cost is low, the effect is good, the seeds do not need to be subjected to germination accelerating, and the emergence rate can reach 95% or above.

Description

technical field [0001] The invention relates to a method for raising seedlings, in particular to a seedling raising method for wild alpine rhododendron with one film and two sheds. Background technique [0002] Alpine Rhododendron is a collective name for cold-resistant, evergreen, and broad-leaved Rhododendron species in the Rhododendronaceae Rhododendron family, accounting for about 70% of all Rhododendron species. The cultivation of Rhododendron has a history of hundreds of years in my country, but it is limited to deciduous or semi-deciduous species of azalea. The understanding of alpine Rhododendron is relatively late, and the seedling cultivation technology is backward. Although many species of Alpine Rhododendron are tall shrubs and trees, the seeds are very small. Traditional sowing seedlings have slow emergence, low germination rate, weak growth and slow growth. Most species can only grow one node per year and are not easy to branch. Rhododendron has few branches, ...

Problems solved by technology

The cultivation of Rhododendron has a history of hundreds of years in my country, but it is limited to the species of azalea with deciduous or semi-deciduous leaves. The understanding of alpine Rhododendron is relatively late, and the technology of seedling cultivation is backward.

Although many species of Alpine Rhododendron are tall shrubs and trees, the seeds are very small. Traditional sowing seedlings have slow emergence, low germination rate, weak growth and slow growth. Most species can only grow one node per year and are not easy to branch. Rhododendron has few branches, long internodes, hard wood, and germinating buds are concentrated on the top of the branches. It is very difficult to propagate by cuttings. In recent years, although there are culture dish seedlings and floating seedlings , but all have relative limitations. For example, culture dish seedlings have higher requirements on the test environment conditions, and labor costs are large; floating seedlings are not convenient to use in the north where water resources are relatively scarce.
