Embodiment 1

[0031] The method of operation includes the following steps:

[0032] (1) Drying and removing wings: Dry the cones of Paleopsis chinensis in the air until the seeds completely fall off, then continue to dry the seeds, rub the seeds with hands when the wings fall off and stop drying, and manually rub the seeds repeatedly to separate the seeds completely, and obtain De-wing the seeds.

[0033] (2) Acquisition of seeds with high fullness rate: use an electric net sorter to remove the winged seeds obtained in step (1), and set the speed to 1000r / min to remove empty seeds, shriveled seeds, insect particles and other sundries, repeat 2 times, Obtain full seeds with high purity (seed fullness rate is more than 80%), and pack into cloth bags.

[0034] (3) Sleep break at low temperature: Store the seeds treated in step (2) in the refrigerator at 3°C ​​and store them at low temperature, take them out one month later and wait for sowing.

[0035] (4) Warm soup degreasing: Put the low-t...

[0041] The method of operation includes the following steps:

[0042] (1) Drying and removing wings: Dry the cones of Paleopsis chinensis in the air until the seeds completely fall off, then continue to dry the seeds, rub the seeds with hands when the wings fall off and stop drying, and manually rub the seeds repeatedly to separate the seeds completely, and obtain De-wing the seeds.

[0043] (2) Acquisition of seeds with high fullness rate: use an electric net sorter to remove the winged seeds obtained in step (1), and set the speed to 1000r / min to remove empty seeds, shriveled seeds, insect particles and other sundries, repeat 2 times, Obtain full seeds with high purity (seed fullness rate is more than 80%), and pack into cloth bags.

[0044] (3) Sleep break at low temperature: The seeds treated in step (2) are stored in the refrigerator at a low temperature of 5°C, and taken out after 2 months for sowing.

[0045] (4)) Degreasing in warm soup: Put the seeds of Chinese fir ...

Abstract

The invention discloses a method for improving the uniformity of germination of Chinese fir, the main technical parameters of which include: (1) Acquisition of seeds with a high plumpness rate: using an electric net sorter for net sorting, replacing the low-efficiency soaking and floating method to remove empty seeds ; (2) Low temperature sleep break: 3 ℃ ~ 5 ℃ short-term low temperature storage, break dormancy. (3) Degreasing in warm NaOH soup: Soak the seeds in continuous warm water for 4 to 5 hours, and then soak in NaOH solution with a mass concentration of 1.0% to 1.5% for 16 hours to complete the degreasing. (4) Seed soaking in clear water and chemical treatment: Soak the seeds in clear water with an initial temperature of 45-55°C for 24h-36h, and then soak the seeds in 500ppm gibberellin solution for 2h; Sprinkle on a flat sand bed, the seeding rate is 0.5-0.6kg / m 2 . Applying the method of the present invention to treat and accelerate the germination of Cedar chinensis seeds, the fullness rate of the seeds before sowing can reach more than 80%, the germination rate in the field after sowing is more than 75%, the germination time is 15 days to 25 days, and the seedling emergence rate in the field is more than 70%. Greatly improved the germination uniformity and field seedling emergence rate of Cedar chinensis seeds, and shortened the germination time.

Description

technical field [0001] The invention belongs to the technical field of forestry planting, and in particular relates to a method for improving the uniformity of germination of Chinese fir. Background technique [0002] Jiangnan oil fir (Keteleeria cyclolepis Flous) is a large evergreen tree belonging to the family Pinaceae. It is unique to southern my country. Its trunk is straight, its wood is solid, and its texture is straight. In addition to its wide range of uses, it is also an excellent tree species for garden greening. The main habit characteristics of this tree species are strong stress resistance, extreme drought tolerance, and fast growth. In recent years, Guangxi, Fujian, Zhejiang, Guangdong, Hunan, Jiangxi and other provinces have begun to pay attention to the promotion and utilization value of Yale fir, and have carried out related research on germplasm resource investigation and collection, seed collection and seedling cultivation, and afforestation models. At p...
