Simple germination accelerating method of torreya grandis seeds

Abstract

The invention discloses a simple germination accelerating method of torreya grandis seeds. The method comprises the steps of (1) seed collection, wherein the sufficiently mature torreya grandis seeds are collected during October and November; (2) seed storage, wherein aril is removed from the seeds, and the seeds are placed in a shady place, paved and kept moisture; (3) seed germination accelerating, wherein a wet sand layer is paved on an outdoor flat soil germination accelerating bed to conduct germination accelerating; (4) temperature-variable germination accelerating, wherein double layers of arcs are built on germination accelerating ridges, the germination accelerating ridges are covered with thin films, and the films are uncovered in daytime and laid on the ridges at might. The germination accelerating method of the torreya grandis seeds has the advantages that the method is simple, small in floor space, extremely easy to operate, short in processing time, high in sprouting rate and even in emergence, and seedlings are strong. Therefore, the germination accelerating of the torreya grandis seeds is more suitable for local conditions of Guizhou, the storage time is 40 days, and the emergence rate reaches 85% or above.

Description

technical field [0001] The invention relates to the technical field of plant seedling cultivation, in particular to a simple method for accelerating germination of Torreya seeds. Background technique [0002] The torreya fruit is rich in nutrition, has a mellow flavor, and has health care, medicinal value, and comprehensive development and utilization value. Generally, the fragrant frame can be used after frying. After the fragrant frame seed is fried, it is crispy and delicious. , the output of incense frames in the existing market is not high, mainly because the cultivation of incense frames has not reached industrialization. [0003] The torreya tree grows slowly, has low survival rate, late fruiting, large investment and late return from the germination of the torreya species to the mature fruit, thereby restricting the large-scale development of the fine variety of torreya. Torreya torreya is an evergreen tree, suitable for growing in a mild, humid, foggy, sunny ecolog...

Problems solved by technology

In the natural state, it takes a long time for the fragrant frame species to germinate. It takes about 2 years to germinate. It takes a long time and the survival rate is low, which greatly affects the industrial production.
