Method for cultivating euscaphis japonica seedlings in container

Abstract

The invention relates to cultivation of shallow dish container seedlings and culturing of container seedlings for seeding of euscaphis japonica. A method for cultivating euscaphis japonica seedlings in a shallow dish comprises the following steps: uniformly sowing germination-accelerated seeds on a shallow seedling cultivating dish filled with a matrix obtained by mixing chaffs, peat soil and yellow soil; covering with the matrix after sowing until the seeds are invisible; watering and placing in an incubator at 25-30 DEG C for cultivation and germination acceleration; or covering with a plastic thin film, and placing at a room temperature of 25-30 DEG C for accelerating germination; when a budding ratio reaches 5-10%, timely shifting out of the cultivation tank or removing the plastic thin film, and transferring into a greenhouse, shading with a shading net having a light transmittance of 30%-50%; timely watering to maintain the humidity of the matrix; cultivating the shallow dish container seedlings. The method is suitable for seeding and cultivating the seedlings in advance in the greenhouse, has a seed sand-storage and germination acceleration time of less than 360 d, has a germination rate of 80% or higher, obtains neat seedlings, and is suitable for industrial cultivation of euscaphis japonica seedlings and container seedlings.

Description

technical field [0001] The invention belongs to a method for raising seedlings of woody plants, in particular to a method for raising seedlings of a medicinal and ornamental plant Arvenia sowing in a container, including shallow dish container bud seedling cultivation and container seedling cultivation. Background technique [0002] Due to the deep dormancy characteristics of the seeds of Jacuna japonica, especially the layer of wax on the seed shell, it is difficult to absorb water without treatment. Generally, the seeds of Javenia japonica have a span of 3 years from seed collection to sowing and emergence, and the emergence rate is low. To obtain a higher seed germination rate and more robust seedlings, the seeds must be stored in sand to accelerate germination; the CN101263758A method for accelerating the germination of Crow Crow seeds, which was applied for and authorized by the inventor in the early stage, has overcome the problem of Crow Crow The deep dormancy and ger...

Problems solved by technology

However, the treatment of the waxy layer of the seed shell is neglected, so it still needs a long treatment time, that is, it takes about 450 days from September or October of the first year to around February or March of the third year before the seeds start Cracks, the time from the cracks to the growth of sprouts is long and not neat, and the germination rate is difficult to exceed 80%, and the nursery is used to sow seedlings, the time controllability is poor, and it is not suitable for industrial seedlings
