Embodiment 1

[0017] A method for selecting escutellaria escutellaria seeds, the specific technical scheme is as follows:

[0018] A. Separate valid and invalid seeds:

[0019] On April 16, 2014, 2 kg of mature seeds of Erigeron lanceolata were harvested from the breeding ground of Yuxi Academy of Agricultural Sciences, and placed in the sun for 3 days until the pappus on the seeds opened. Prepare a plastic bucket with a capacity of 20L and fill it with 180 times the detergent solution, and soak the seeds in the solution for 2 hours. Take out the invalid seeds floating on the surface, leave the effective seeds that sink to the bottom, pack the effective seeds in gauze bags, rinse them with clean water, wring out the water, and dry them in the air until the pappus of seeds opens;

[0020] B. To remove the pappus:

[0021] Pack the dried seeds in a gauze bag and rub the seeds until the pappus falls off. Spread an 8-thread-thick plastic film on a clean and dry indoor floor, prepare an ele...

Embodiment 2

[0025] A method for selecting escutellaria escutellaria seeds, the specific technical scheme is as follows:

[0026] A. Separate valid and invalid seeds:

[0027] On April 16, 2014, 2 kg of mature seeds of Erigeron lanceolata were harvested from the breeding ground of Yuxi Academy of Agricultural Sciences, and placed in the sun for 3 days until the pappus on the seeds opened. Prepare a plastic bucket with a capacity of 20L and fill it with 220 times of detergent solution, and soak the seeds in the solution for 1 hour. Take out the invalid seeds floating on the surface, leave the effective seeds that sink to the bottom, pack the effective seeds in gauze bags, rinse them with clean water, wring out the water, and dry them in the air until the pappus of seeds opens.

[0028] B. To remove the pappus:

[0029] Pack the dried seeds in a gauze bag and rub the seeds until the pappus falls off. Spread a 5-thread-thick plastic film on a clean and dry indoor floor, prepare an electr...

Abstract

The invention relates to a seed careful selection method, and particularly relates to a selection method of erigeron breviscapus (vant.) hand.-mazz seeds. According to the technical scheme, the selection method of the erigeron breviscapus (vant.) hand.-mazz seeds comprises the following steps: A. separating useable seeds from useless seeds; and B. removing pappus. With the adoption of the careful selection method of the erigeron breviscapus (vant.) hand.-mazz seeds, most of pathogenic bacteria carried by the surfaces of the seeds can be extinguished and removed, so that the disease damage in the seedling period can be reduced; the germination rate and the seedling rate of the seeds can be increased; the size of the obtained pure seeds is less than 5 times that of the original seeds, so that the sowing precision is increased, the seedling emergence is fast and uniform, the seedling rate is increased by about 35 to 40% and reaches 80 to 85%, and the seedlings are uniform and strong; after transplanting, the seedlings of the carefully-selected erigeron breviscapus (vant.) hand.-mazz seeds are free of rejuvenation period and grow strongly and uniformly; 30 to 50kg of dry products per mu is increased, and the added output value reaches 600 to 1000 Yuan.

Description

technical field [0001] The invention relates to a method for selecting seeds, in particular to a method for selecting seeds of Erigeron breviscapine. Background technique [0002] Erigeron breviscapus (Vant.) Hand.-Mazz., also known as Erigeron breviscapus (Vant.) Hand.-Mazz., is a perennial herb belonging to the Aster family of Asteraceae. The mixed crystals of flavonoids contained in it are called scutellarin. It is currently the best natural biological drug for the treatment of obliterative cerebrovascular diseases and sequelae of cerebral hemorrhage, with an effective rate of over 95%. It has been designated as an essential Chinese patent medicine in the emergency department (room) of Chinese hospitals nationwide, and listed as a national protected variety of traditional Chinese medicine, which has broad development prospects in the pharmaceutical industry. Due to high market demand and over-excavation, wild resources are on the verge of extinction. Artificial plantin...
