Problems solved by technology

It has been reported in the literature that it will take several days for the cones to crack under the condition of sun exposure; when dealing with Yunnan pine cones, the temperature should not exceed 50°C, and the seed germination rate of the cones at 50°C lasts for 50 hours will drop
Therefore, it is extremely difficult to obtain Yunnan pine seeds and have a good germination rate

Embodiment 1

[0019] (1) Harvesting cones: During the maturity period of Yunnan Pine cones in December each year, select healthy and mature cones, cut them off with high branch shears and bring them back indoors for later use.

[0020] (2) Cone baking: Use a temperature-controllable drying oven, manually set the temperature condition of 50°C, put the obtained cones into the drying oven, bake for 40 minutes, and the cones will crack. The fruit is placed on a white disk or an agricultural dustpan, the cones are rolled, and the seeds are successively released from the cones, and the protruded seeds are separated by a sieve for sowing for later use. The seed germination rate was 95.3%.

Embodiment 2

[0022] (1) cone harvesting: with embodiment 1.

[0023] (2) Cone baking: Use a temperature-controllable drying oven, manually set the temperature condition of 55°C, put the obtained cones into the drying oven, bake for 37 minutes, and the cones will be cracked. The fruit is placed on a white disk or an agricultural dustpan, the cones are rolled, and the seeds are successively released from the cones, and the protruded seeds are separated by a sieve for sowing for later use. The seed germination rate was 96.8%.

Embodiment 3

[0025] (1) cone harvesting: with embodiment 1.

[0026] (2) Cone baking: Use a temperature-controllable drying oven, manually set the temperature condition of 55°C, put the obtained cones into the drying oven, bake for 30 minutes, and the cones will crack. The fruit is placed on a white disk or an agricultural dustpan, the cones are rolled, and the seeds are successively released from the cones, and the protruded seeds are separated by a sieve for sowing for later use. The seed germination rate was 96.1%.

[0027] Wherein taking embodiment 2 as preferred embodiment.

Abstract

The invention discloses a method for rapidly obtaining Yunnan pine seeds. The method comprises the following steps: 1, harvesting cones; and 2, baking the cones. The method for rapidly obtaining Yunnan pine seeds allows the seeds to be rapidly obtained within 30-40min and the seed germination rate to reach 95% or above. The method has the advantages of simple and easy operation, few device requirements, low cost, simple technical requirements, and easy popularization and application, and has important application and popularization values in aerial sowing forestation of Yunnan pine seeds.

Description

technical field [0001] The invention relates to the technical field of crops, in particular to a method for rapidly obtaining pine seeds. Background technique [0002] Yunnan pine (Pinusyunnanensis) is an evergreen forest tree conifer species of Pinaceae (Pinaceae). Forest. The cones of Pine yunnanensis will not open scales to release seeds immediately after they mature, and the closed cones will persist on the branches for many years. It has been reported in the literature that it will take several days for the cones to crack under the condition of sun exposure; when dealing with Yunnan pine cones, the temperature should not exceed 50°C, and the seed germination rate of the cones at 50°C lasts for 50 hours will drop. Therefore, it is extremely difficult to obtain Pine yunnanensis seeds and have a good germination rate. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of ...
