Germination method of Norway maple seed

Abstract

The invention discloses a germination method of Norway maple seeds, which comprises the steps as follows: firstly, the crusts of the Norway maple seeds are stripped, and then the seeds are dipped in water at 25 DEG C, to ensure the seeds to fully absorb water; then 1 to 3 meshes of vermiculite is mixed with the seeds, the mixing ratio of the vermiculite to the seeds is 3:1, then a conditioning agent is added, and the weight of the conditioning agent accounts for 0.5 to 1 percent of the weight of the seeds with the crusts being stripped; the admixture of the vermiculite and the seeds is put into a sealed container, and put into a refrigerator with the temperature being 2 to 5 DEG C, whether the seeds have breaches are observed for one time every three days from the 20th day, and when one third of the seeds have breaches, the seeds can be used for sowing and germination. The method has high operability and easy operation, is slightly influenced by the external climatic factor, and can be performed all the year round; and the germination period is short, which is 26 days generally, and the germination percentage is above 58 percent.

Description

Technical field: [0001] The invention relates to a seed germination method. Background technique: [0002] At present, sand storage is generally used for accelerating germination of the American Norwegian maple. This treatment has high requirements on environmental conditions and is generally only suitable for spring sowing. It has a long germination period (generally 48 days) and a low germination rate (generally 35%). Invention content: [0003] The purpose of the present invention is to provide a method for germination of Norway maple seeds which are less affected by external climate, have a short germination period and a high germination rate. [0004] Technical solution of the present invention is: [0005] A kind of Norway maple seed germination method is characterized in that: comprises the following steps successively: [0006] (1) First peel off the shell of the Norway maple seeds, and then soak the seeds in water with a temperature of 25° C. for 24 hours to mak...
