Several methods of promoting seed of Hawthorn

Hawthorn taste sour sweet, is a lot of people like to eat sour favorite fruit. It can not only be eaten directly, but also processed into hawthorn slices, dried hawthorn and other small snacks. But hawthorn seed is very hard, germination rate is low. Today, Xiaobian brings several ways to improve the germination rate of hawthorn seeds.

1. Sand storage method of early seed collection and temperature change treatment

Hawthorn seeds can be harvested in advance and the germination speed can be accelerated. Hawthorn seeds can be harvested when they are mature in September. It is better to harvest seeds before the fruit is completely colored. Because at this time the seeds have basically matured, but not yet fully hardened and not stitched, this is conducive to germination. Crushing the harvested fruit but remember not to destroy the seeds, take out the seeds and wash them with water, stir them in boiling water above 90 degrees for 5 minutes, remove them and cool them with cold water, and soak them all day. The next day, take it out and expose it to the sun. Turn it once an hour to heat the seeds evenly. Soak them in water at night. Repeat the exposure the next day. This is conducive to cracking the seed shells ahead of time. Then you can prepare for sand storage. In the second year, a few seeds will have germinated and you can sow them.

2. Early seed collection and sand storage method

As with the method of early seed collection and sand storage, harvest seeds in advance, crush the pulp, take out seeds and wash them with water. Then put the seeds in a container and soak them in cold water for about 10-15 days, changing the water every 2-3 days. When removing seeds, sand them while they are still wet. Stir well and put into the pit. Dig a pit about one meter deep and 0.8 meters wide in the leeward area. The length depends on the situation and is determined by the number of seeds. Spread the stirred seeds flat into the bottom of the pit, put a layer of wood about 10 cm away from the seeds, put a piece of ventilated cloth on the wood, and put a handful of rice stalks or straw on the cloth for ventilation. Then fill the pit, in order to prevent water in the pit should be slightly higher than the ground level, sand storage in June-July, and then spring sowing. Such seed germination rate can be greatly improved.

3. Horse manure fermentation method

Harvesting seeds in autumn, blanching the seeds with hot water and soaking in warm water for 3-5 days. It should be noted that when the water temperature is lower than the body temperature, the water should be changed. After soaking, remove the seeds and stir them with horse dung. The ratio is about 1:4. After stirring, put it into a dug pit, 40 cm deep, and cover it up after putting it in. The seeds are heated to about 37 degrees Celsius. A month to two months after the seeds that crack, take out and then spring sowing, this method can emerge in the same year.

The above three kinds are the methods summarized by Xiaobian to improve the germination rate of hawthorn seeds, although the seeds in mature hawthorn are very hard and the germination rate is very low. However, it is possible to take seeds when hawthorn is not fully mature, and then use the method of small compilation to germinate, or it can greatly improve the germination rate of seeds!
