Embodiment 1

[0009] Embodiment 1: operate according to the following steps:

[0010] (1) Pretreatment before germination. Choose fully mature torreya seeds between October and November every year, and the best harvest is when the arils are cracked and some of them fall off. Immediately after harvesting, the arils are peeled or stacked for no more than a week. Once the arils are rotten, the seeds are peeled and spread in a cool place with a thickness of 20cm. Covered with straw to keep moisture, to avoid dry and wet and stacking for fermentation.

[0011] (2) Germination in the nursery. Before November 15th, bring the above-mentioned prepared seeds to the nursery, first spread 10cm thick wet sand on the nursery, then sprinkle the seeds, without overlapping, and then cover with wet sand, so as not to see the seeds. (the wet sand here has a moisture content of 8%, which can be moistened by hand but without water seepage). Cover it with a layer of 1.5cm thick straw to keep moisture, and the...

Embodiment 2

[0014] Embodiment 2: each step and method of operation are all the same as embodiment 1, and the difference is (2) germination in the nursery, the seed layer sown and the wet sand layer on it are respectively two layers, and are arranged at intervals one by one. The advantage is that it saves plots and sheds, and it is convenient for centralized management; the disadvantage is that it increases the difficulty of management, and the germination rate of seeds in the lower layer is slightly lower than that in the upper layer.

[0015] By using the method for accelerating germination of the present invention, the average germination rate of Torreya seeds is about 80%.

Abstract

The germination accelerating method for Chinese torreya seed includes collecting mature Chinese torreya seed, eliminating aril, spreading in shade place while maintaining humidity for at most one week, germination accelerating in wet sand layer inside nursery land, covering with short arched plastic shed and high plastic shed, and conventional management. The present invention has one time raised Chinese torreya seed germination ratio, low cost and capacity of cultivating great amount of Chinese torreya stock seedlings.

Description

technical field [0001] The invention relates to a method for accelerating the germination of Torreya seeds, in particular to a method for accelerating the germination by using high and low double plastic sheds to increase the temperature. Background technique [0002] Torreya grandis (Torreya, grandis'Merrillii') is a rare dried fruit unique to my country. It is an excellent cultivar that has been grafted and propagated from Torreya grandis (Torreya grandis Fort.ex Lindl.). It is crispy, nutritious, and has health care functions. The price per kilogram is more than 200 yuan. Torreya torreya (commonly known as torreya), which is propagated by seedlings, has hard and thick seed shells, thick and hard meat, no fragrance, and poor taste. The price is only 1 / 5 of that of torreya, but the resources are more abundant than torreya. Using Torreya seeds to sow and raise seedlings as rootstocks for grafting Torreya torreya has the advantages of rich seed resources and reduced seedling ...
