Several methods of promoting seed of Hawthorn

Hawthorn tastes sour and sweet, and it is the favorite fruit of many people who like to eat sour food. It can not only be eaten directly, but also can be processed into Hawthorn slices, dried Hawthorn and other small snacks. But Hawthorn seeds are hard and the germination rate is low. Today, the editor has brought several ways to improve the germination rate of Hawthorn seeds.

The main results are as follows: 1. Early seed collection and variable temperature treatment of sand storage.

The speed of seedling emergence of Hawthorn seeds collected in advance can be accelerated, and Hawthorn seeds can be harvested when Hawthorn is mature in September. It is more appropriate to collect seeds before the fruit is thoroughly colored. Because at this time the seeds are basically mature, but they are not completely hardened or stitched, which is conducive to germination. Crush the harvested fruit but remember not to destroy the seeds. Wash the seeds with water, stir them in boiling water above 90 degrees for 5 minutes, cool them with cold water and soak them for a whole day. Put it out in the sun the next day and turn it once an hour to heat the seeds evenly, soak them in the water in the evening, and repeat the sun the next day, which is conducive to the early cracking of the seed shell. Then you can prepare for sand storage, and in the second year, a small number of seeds will have germinated and can be sown.

2. Sand storage method of early seed collection

Like the method of early seed collection and variable temperature treatment of sand storage, the seeds are harvested in advance, and the pulp is crushed and the seeds are washed with water. Then put the seeds in a container and soak them in cold water for about 10-15 days and change the water every 2-3 days. When taking out the seeds, hide them while the seeds are still wet. Stir evenly and put into the pit. Dig a pit about one meter deep and 0.8 meters wide in the leeward area of Xiangyang. The length depends on the situation and depends on the number of seeds. Spread the stirred seeds flat into the bottom of the pit, build a layer of wood about 10 centimeters away from the seeds, put a 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 the accumulation of water in the pit should be slightly above the ground level, sand storage in June-July, and then spring sowing. The germination rate of such seeds can be greatly improved.

3. Horse dung fermentation

Collect seeds in autumn, scald the seeds with hot water and soak them 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, the seeds are mixed with horse dung, the ratio is about 1:4. After stirring, put into the dug pit, pit depth of 40 cm, put in cover, the seed fever to about 37 degrees. The seeds will crack in one to two months, and then sowed in spring after being taken out. This method can produce seedlings in the same year.

The above three are the methods summarized by the editor to improve the germination rate of Hawthorn seeds, although the mature Hawthorn seeds are very hard and the germination rate is very low. But can be taken when Hawthorn is not fully mature, and then use the method of Xiaobian to promote germination, or can greatly improve the germination rate of seeds!
