Planting techniques of Eucommia ulmoides Oliv. Planting time and methods of Eucommia ulmoides

As we all know, Eucommia ulmoides is a very precious tree species in China, because its bark can be used as medicine, it is a precious traditional Chinese medicine, and the efficacy of health care is also very high. So do you know how to plant Eucommia ulmoides trees? The following editor will introduce you to the planting method of Eucommia ulmoides.

Planting techniques of Eucommia ulmoides

1. Pre-broadcast preparation

Put the seeds into a plastic souvenir bag, hang them in a cool and ventilated place, and sow them directly into the border in late December. The seeds of Eucommia ulmoides were collected at the end of October, hung and stored, soaked in clean water for 1-2 days in late December, changed the water once a day, and added less copper sulfate or ammonium benzoate (zinc) and carbendazim in the last change of water, so as to kill the bacteria and filter them so that they could spread without sticking hands when sowing, and sow seeds directly into the border. The life span of Eucommia ulmoides seeds is 1 year, and the seed germination rate is closely related to maturity and freshness. the germination rate of mature seeds is low, and the germination rate of spring sowing is even lower.

2. Soil preparation and fertilization

Choose Shatian or sandy loam field, plough and rake repeatedly for 2 or 3 times before sowing. The compound fertilizer "stubble" before the last ploughing and harrowing. Make a 1-meter border, cut 20-25 cm deep, apply ring fertilizer or sprinkle compound fertilizer and vegetable cake in the ditch, or use human and animal urine feces to make the bottom, covering soil 1.5-2 cm below the border surface.

3. Planting into the bed

In the ditch where the base fertilizer is applied, put a seed between 5 cm or sprinkle it sparsely and evenly in the ditch, and those who are too dense will pick up another sparse place. Cover vegetation ash mixed with soil or fine soil 1.5 cm. Along the ditch on the border, the rice and thatch are kept warm. The cover grass does not need to be too thick, so as not to bring out the seedlings when lifting the grass.

Planting time and method of Eucommia ulmoides

It is usually propagated with seeds. Seeds can be sowed in spring and autumn. Soak the seeds in warm water of 40-50 ℃, stir constantly, remove them until the water is cool, soak them in cold water for two days, wait for the seeds to expand, and mix them with fine sand. Dig a hole in the sunny place, put the mixed seeds in the pit, pour water and moisturize, cover with a layer of plastic film, stir every 1-2 days, and sow when the seeds sprout. Strip sowing, open 2 cm shallow ditch according to the row spacing of 25 cm to 30 cm, sow the seeds evenly into the ditch, push them flat with a hoe, and keep the border surface moist before emergence. Transplanting in spring or winter, digging holes according to row spacing and plant spacing of 3 meters respectively, the roots should be stretched when the seedlings are planted, and then covered with soil, compacted and watered.

Growth environment of Eucommia ulmoides

Eucommia ulmoides likes the warm and humid climate and sunny environment, can withstand severe cold, and the adult plant can survive normally under the condition of-30 ℃. It can be cultivated in most areas of our country with strong adaptability and no strict selection of soil, but the loam with deep soil layer, loose and fertile soil, moist and good drainage is the most suitable. The growth rate of Eucommia ulmoides trees was slow in their infancy, and the fast-growing period appeared in 7 ~ 20 years. After 20 years, the growth rate decreased year by year. After 50 years, the height growth basically stopped and the plants withered naturally.

Seedling stage management

1. Spraying to protect seedlings: Eucommia ulmoides should be sprayed to control locusts, gibberries, longicorn beetles and other pests during the whole seedling stage. Bordeaux liquid can prevent blight, but it is useless to spray Bordeaux liquid after the seedlings get blight, so Kangkuling and carbendazim should be irrigated. At the same time, it is necessary to hoe the surface shallowly to increase the ground temperature and irrigate more light fertilizer to enhance soil fertility. Downy mildew can be sprayed or irrigated with mancozeb, mancozeb and carbendazim.

2. Pulling grass and loosening soil: after emergence, Eucommia ulmoides seeds should pay attention to ploughing and weeding, watering and fertilizing, loosening the soil. Seedlings avoid the scorching sun, should be properly shaded, sprinkler irrigation should be timely to prevent drought in the dry season, and attention should be paid to waterlogging in the rainy season. If the trunk of the seedling is bent, it can remove all the aboveground parts along the surface in early spring, promote the development of new branches, and leave a strong and straight new branch as the new trunk, and all the rest can be removed.

3. Rational fertilization: Eucommia ulmoides seedling fertilization should be "eat less and eat more", farm manure and compound fertilizer should be better, fertilization should be light, thinning after each loosening soil is appropriate, ammonium bicarbonate should not be used to prevent fertilizer damage. After the seedling height is 30 centimeters, you can spread urea on rainy days, with a dosage of 4-5 kg per mu. After the seedling height is 40 cm, urea can be sprinkled lightly every 15-20 days. Eucommia ulmoides seedlings grow sharply in autumn, fertilizer to keep up, the big one can grow 100 to 110 centimeters high, can cultivate high-quality seedlings.

The above is a summary of the planting methods of Eucommia ulmoides for you. I hope it can help you. Eucommia ulmoides bark has the effects of fixing menstruation and calming the fetus, strengthening muscles and bones, tonifying the liver and kidney, and so on, so it is a very popular medicinal material in the market, so the prospect of planting Eucommia ulmoides is relatively broad.
