The Latest Technical Method Tutorial for Sowing and Raising Eucommia ulmoides Seedlings
Eucommia ulmoides is a medicinal plant that contains a variety of amino acids and minerals, as well as many trace element components. It is a precious medicinal herb in our country, of great economic value for making medicine, and it can also help more patients and be used to produce many health-care medicines. Growing Eucommia ulmoides is mainly done by sowing and raising seedlings, and sowing and raising seedlings can pass on good shape characteristics and gives a relatively high guarantee of planting yield. So now the key technical points of sowing and raising Eucommia ulmoides seedlings will be introduced.
1. Seed treatment
Eucommia ulmoides seeds contain a component called eucommia gum, so their binding force is relatively strong and they do not germinate naturally very easily, so artificial germination prompting is needed. For Eucommia ulmoides, the commonly used method of prompting germination is the sand method: dig a pit about 1 m deep in a high, wind-sheltered, sunny place, then place 10 cm of sand at the bottom of the pit, then mix the seeds evenly with sand, with the sand being about three times the amount of the seeds. Put them into the pit, then cover with 15 cm of sand, note that the edges all need to be separated with straw so air can pass through, and on top also cover with about 20 cm of soil. After about a week they will sprout; sieve out the sand and then sow, but if some have not germinated, soak them again for one day in 20°C warm water.
2. Land preparation
First choose a deep soil layer, wind-sheltered and sunny, water- and fertilizer-retaining, well-drained and loose sandy loam for planting. When sowing, first turn the soil and deep plow, then rotary till and finely till the soil, breaking up large clods of earth. Finally apply basal fertilizer well, about 1000 jin per mu, and after mixing with the soil, cover the surface with 10 cm of topsoil for planting, and finally level the land.
3. Sowing
For sowing time, it is best to sow in spring in April and in autumn in October, when temperature and humidity are suitable and seedlings emerge and survive easily. For sowing, dig furrows for row sowing; generally it is good to dig furrows 10 cm deep and 30 cm wide, water in the furrow, and after it seeps through, directly scatter the seeds evenly in the furrow, and finally cover with soil just enough to cover the seedlings as they emerge. The furrow spacing can be about 20 cm, enough for a person to pass through. About 200 to 400 jin of seeds are sown per hectare.
4. Seedling-stage management
About 20 days after emergence, when the seedlings have grown about 5 leaves, begin checking and filling in gaps with new seedlings; fill in gaps carefully on cloudy days, and do it early so the new seedlings can catch up with the earlier growth period. The growing distance directly between seedlings should leave a gap of about 2 cm. Fertilization should be combined with watering; for autumn planting, water less and fertilize less, and do not shade, as Eucommia ulmoides has relatively strong resistance.
The above is the seedling-raising process for growing Eucommia ulmoides. Raising seedlings is the key to planting; only by raising seedlings can you plant, and only by raising good seedlings can you ensure good growth of Eucommia ulmoides. Proficiency in seedling raising is what enables efficient seedling raising on a large scale, can shorten the seedling-raising time, and produce a large number of seedlings in a short time.
