Sowing and Seedling-raising techniques of Eucommia ulmoides

Eucommia ulmoides is a medicinal plant, which contains a variety of amino acids and minerals, as well as many trace elements. It belongs to the precious medicinal materials of our country, and it is of great economic value to be used in pharmaceuticals. it can also help more patients and produce a lot of health care drugs. The main purpose of planting Eucommia ulmoides is to sow and raise seedlings. Sowing u seedlings can inherit good shape characteristics and have high guarantee for planting yield. So now we would like to introduce the technical points of sowing and raising seedlings of Eucommia ulmoides.

I. seed treatment

Eucommia ulmoides seeds have an ingredient called Eucommia ulmoides gum, so the adhesion is strong, it is not easy to germinate naturally, and requires artificial germination. For Eucommia ulmoides, sand is commonly used to dig a pit about 1 meter deep in a higher place where the leeward is sunny, then put 10 cm thick sand at the bottom of the pit, and then mix the seeds with sand, which is about three times the size of seeds. Put it in the pit and cover it with 15 cm thick sand. Note that the edges need to be separated by straw, which can be breathable, and the top should be covered with about 20 cm of soil. It will sprout in a week or so, sift out the sand with a sieve before sowing, but if it has not germinated, soak it in warm water of 20 degrees for another day.

II. Land preparation

First choose the deep soil layer, leeward to the sun, water and fertilizer conservation, permeable loose sandy soil to plant. When sowing, the soil should be ploughed deeply first, and then the soil should be ploughed by rotary ploughing and fine ploughing to break large chunks of soil. Finally, about 1000 jin per mu of base fertilizer is applied, and the surface of the mixed soil will also be covered with 10 cm of topsoil for planting, and finally flatten the land.

Third, sowing seeds

The sowing time of one year can be the best in spring, April and autumn, and the temperature and humidity are suitable, so it is easy to emerge and survive. Sowing to dig a ditch to apply, it is generally good to dig a ditch 10 cm deep and 30 cm wide, water in the ditch to be infiltrated and then spread directly and evenly in the ditch, and finally cover the soil to the height of the unearthed seedlings. The distance between the trenches is 20 centimeters and can be crossed by pedestrians. Sow about 200 to 400 jin of seeds per hectare.

IV. Management at seedling stage

About 20 days after emergence, when the seedlings grow out of about 5 leaves, we should begin to check the replenishment of the seedlings, which should be meticulous in cloudy days and should be early in order to catch up with the previous growth period. The direct growth distance between the seedling and the seedling should be about 2 cm. Fertilization should be combined with watering, planting in autumn should be less watering, less fertilization, not shading, Eucommia ulmoides has strong resistance.

The above is the seedling process of Eucommia ulmoides planting, seedling is the key to the cultivation of seedlings can be planted, good seedlings can ensure the good growth of Eucommia ulmoides. Only by being skilled in raising seedlings can we raise seedlings efficiently in a large area, shorten the time of raising seedlings, and produce a large number of seedlings in a short time.
