Seed treatment method for neat seedling emergence of euscaphis japonica seeds

Abstract

The invention relates to a seed treatment method for neat seedling emergence of euscaphis japonica seeds. The seed treatment method comprises the following steps: uniformly mixing harvested, impurity-removed and selected seeds and river sand in the volume ratio of 1 to 3 every year; placing the mixture in a wood box with good drainage; after 300 days, adding 0.5 to 1 weight percent of plant ash, mixing uniformly, and watering often to keep the humidity, wherein the humidity is suitable when the mixture kneaded by a hand can form dough; the seeds start to crack on 350 to 360 days, and the seedscan be screened for sowing when the number of cracks reaches 3 to 5 percent. The germination rate of seed seedlings is over 80 percent; the treatment time is shorter than 360 days; the time from sowing to germinating and growing into bud seedlings is short; the seedlings emerge neatly; the sowing time controllability is high; the euscaphis japonica seed treatment method or a germination accelerating method is suitable for industrialized seedling production; the euscaphis japonica seeds can germinate indoors about three months earlier; the height of the seedlings which are transplanted in a nursery land for planting in current year can reach over 80 cm; bare roots in the current year can be delivered out of the nursery land.

Description

technical field [0001] The invention belongs to a method for growing seedlings of economic forests or ornamental plants, in particular to a seed treatment method for the orderly emergence of seeds of the medicinal and ornamental plant Jacuna japonica. Background technique [0002] The so-called Arvenia seeds in the present invention include the seeds of Arvenia genus and Arvenia genus of the genus Arvenia, which is an emerging and fast-growing important ornamental and medicinal plant in the market. Native tree species. However, due to the characteristics of deep dormancy 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 Javenica japonica have a span of 3 years from seed collection to sowing and emergence, and the emergence rate is low. In order to obtain a higher seed germination rate and more robust seedlings, the seeds must be stored in sand to accelerate germination; ...

Problems solved by technology

However, the treatment of the waxy layer of the seed shell has been neglected, so it still needs a long treatment time, that is, it will take about 450 days to the end of February and early March of the third year before the seeds begin to crack. The time is long and not neat, and the germination rate is difficult to exceed 80%. The controllability of the sowing time is poor, and it is not suitable for industrial seedling cultivation
