Embodiment 1

[0042] S1. Picking of star anise fruit: picking seeds from the fruit of the excellent tree, the selection of the mother tree should be the type of soft branch safflower, the tree age is 20-40 years old, the growth is vigorous, the fruit is good in the big and small years, the fruit is large, the follicles are complete and full, and there are no diseases and insect pests. The star anise tree is the mother tree for seed collection. The star anise fruit matures in mid-October. When the fruit is fully mature from yellow-green to yellow-brown, it is harvested, and the seed moisture content is 25-30%;

[0043] S2. Collection of star anise seeds: The fresh star anise fruits that are picked are directly exposed to the sun and dried for 3-4 days. During this period, the fruits are often turned to cause the fruits to crack and release the seeds. After the seeds are ejected, they must be stored in time, and the separated seeds should be collected every day. 2 - 3 times and temporarily sto...

Embodiment 2

[0048] S1. Picking of star anise fruit: picking seeds from the fruit of common fruit trees, star anise fruit matures in mid-October, when the fruit is fully mature from yellow-green to yellow-brown, the seed is harvested, and the water content of the seed is 25-30%;

[0049] S2. Collection of star anise seeds: Put the fresh star anise fruits collected in a cool place, ventilate or turn threshed seeds intermittently in time and collect and store them in time. The threshed seeds should be selected before sowing;

[0050] S3. Wet sand storage and germination of star anise seeds: The selected seeds are placed in the wet river sand and evenly mixed, and the river sand is sieved with a 40-mesh standard sieve. The mass ratio to the seeds is 10:1, so that each seed is surrounded by sand and does not touch each other, and then put the evenly mixed seeds into the storage box for storage, and the bottom of the storage box is covered with 2cm thick wet sand, Spread the wet sand mixed with...

[0054] S1. Picking of star anise fruit: picking seeds from the fruit of the excellent tree, the selection of the mother tree should be the type of soft branch safflower, the tree age is 20-40 years old, the growth is vigorous, the fruit is good in the big and small years, the fruit is large, the follicles are complete and full, and there are no diseases and insect pests. The star anise tree is the mother tree for seed collection. The star anise fruit matures in mid-October. When the fruit is fully mature from yellow-green to yellow-brown, it is harvested, and the seed moisture content is 25-30%;

[0055] S2. Collection of star anise seeds: The fresh star anise fruits that are picked are directly exposed to the sun and dried for 3-4 days. During this period, the fruits are often turned to cause the fruits to crack and release the seeds. After the seeds are ejected, they must be stored in time, and the separated seeds should be collected every day. 2 - 3 times and temporarily sto...

Abstract

The invention discloses a novel method for increasing the germination rate of anise seeds, which comprises the following steps: picking anise fruits: picking seeds from superior tree fruits, selecting robust anise trees which are of a soft-branch safflower type, are 20-40 years old, grow vigorously, bear good fruits in big and small years, have large fruits, complete and full follicles, are free from diseases and insect pests and the like as seed-collecting seed trees, and selecting anise trees as seed-collecting seed trees; illicium verum fruits are matured in the middle ten days of October and are harvested when the fruits become yellowish-brown from yellow green and are fully matured, and the water content of the seeds is 25-30%; collecting anise seeds: timely tedding picked anise fresh fruits, or placing the anise fresh fruits in a ventilated place to thresh the seeds, or directly obtaining the seeds by stripping the fresh fruits, the method improves the seed cultivation quality by selecting superior tree fruits, timely collects the seeds, avoids long-term airing and drying of the seeds and volatilization of moisture and oil, and improves the quality of the seeds. The water in the seeds is locked in a wet sand storage manner, so that the germination rate of the seeds is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of promoting the germination of star anise seeds in sand, in particular to a new method for improving the germination rate of star anise seeds. Background technique [0002] Star anise, also known as star anise, is an evergreen tree, originally wild in the southern subtropical region of my country, and is the only species in the star anise genus that has economic value and can be directly used as an edible raw material for large-scale artificial cultivation. Cultivation of star anise can produce great economic benefits and is highly valued by people. It is mainly distributed in Guangxi, Yunnan, Guangdong and other regions in southern China. The fruit of the genus Octagon is aggregated follicles, arranged radially in a single round, the exocarp and mesocarp of each mature carpel are fleshy, thick, and the endocarp is bony. Seeds are bombarded with timed mechanical pressure, containing 1 seed per mature carpe...
