Method of accelerating germination of woody flower seeds

There are mainly five kinds of budding methods of forest flower seeds, which are seed soaking method, stratification method, dewaxing and deoiling method, peeling method and Yang bed method. Here are five methods in detail.

Seed soaking method

Some seeds need to be soaked in cold water or warm water before sowing, so that the seeds can absorb water and sprout earlier after sowing; some seeds just need to be sprayed with warm water before sowing to make the seeds moist and evenly, dry the seeds and sow them.

Usually, small seeds can be sowed after soaking in cold water for 3-5 days; seeds with thick seed coat need to be soaked in warm water of about 45 degrees for 3-5 days. The seeds of Robinia pseudoacacia, peach, plum and apricot should be scalded with hot water.

Concrete operation

Put the seeds into the cylinder and pour in about 85 degrees of hot water, the amount of water is 2-3 times the volume of the seeds, pour water while stirring, so that the seeds can be heated evenly, and then let the water cool naturally. After that, rinse 1-2 times a day with warm water of 45 degrees, wait for the seeds to "crack" before sowing.

Stratified budding method

This method is very effective for seeds with long dormant period and slow germination. The selected sand should be washed clean, and the humidity of the sand should be kept without dripping or loosening. The wet sand and seeds should be stored in a low temperature of 0-5 degrees. When the seeds show signs of germination, they can be sown.

Dewaxing and deoiling

This method is used for seeds with waxy or greasy skins.

Concrete operation

Soak the seeds in 70 degrees ash water or a mixture of water and alkali noodles, rub the wax skin or grease after cooling, rinse with clean water, pick them out, sprout with raw bean sprouts, and sow seeds when the seeds are "cracked".

Skin breaking method

If the seed coat of the seed is very hard, the seed coat can be cut and germinated.

Yang bed budding method

Fill the fine sawdust or wheat bran into the hotbed, 10 cm thick, flatten, pour thoroughly, and spread the treated seeds evenly. After sowing, cover about 1 cm of sawdust, spray water through the sawdust and cover it with film. The "split mouth" of the seed can be taken out and sown, or you can wait for the seed to sprout and transplant.
