Effect and function of Eucommia

[origin distribution] mainly produced in Hubei, Sichuan, Guizhou, Yunnan, Shaanxi and other provinces Most of them are cultivated Seed planting technology of Eucommia ulmoides Oliv Methods 1 Before sowing, put the seeds into plastic woven souvenir bags, hang them in a cool and ventilated place, and sow them directly in the border in late December The seeds of Eucommia ulmoides Oliv Were collected at the end of October and stored in suspension In the late December, they were soaked in clear water for 1-2 days and replaced with clear water once a day When Zui changed the water for the next time, copper sulfate, ammonium (zinc) and carbendazim were added less, so as to remove the pathogens and filter them until they were able to spread their hands when they were seeded and directly seeded in the border The life span of Duroc seed is one year, and the germination rate is closely related to maturity and freshness The germination rate of mature seeds is lower than that of spring seeds 2 Seeded in the border 1 Ploughed and raked twice or three times before sowing The "stubble" of compound fertilizer should be applied before the last ploughing of Zui It can be made into a 1-meter border, 20-25 cm deep The furrow can be fertilized or spread with Hefei and vegetable cake It can also be bottomed with human and animal urine dung, and the soil cover is 1.5-2 cm lower than the border surface 2 Put one seed between 5cm in the furrow with base fertilizer or scatter it evenly in the furrow, and pick up another place where it is too dense 1.5-2CM of mixed soil or fine soil covered with grass, wood and ash Lay rice and thatch on the border along the ditch to keep warm It is not necessary to cover the grass too thick, so as not to take out the seedlings when the grass is lifted after the seedling is complete 3 After the rice straw was used to cover the border, the mice were attracted very quickly, and the mice were severely bitten by Eucommia seeds The rats must be baited immediately 15~20 days before the seedlings were unearthed, they were mixed with 1:3 carbofuran and loess to spread the border surface, killing tigers When the seedlings are ready, remove the straw and thatch, and sprinkle the 1:4 longevity Baichong powder, plant ash and fine soil once more In case of drought during the seed filling stage of withered seeds or Eucommia ulmoides Oliv, the flesh inside the seeds is black Do not have the lucky psychology of "spreading and watching", and do not raise seedlings together with the strong seeds, so as to prevent the strong seeds from infecting with bacterial wilt after emergence 3 Management of seedling stage 1 Transplanting the seedlings with too dense seedlings to keep the plant spacing about 8-10cm It is better to transplanting the seedlings after they are basically full, and transplanting the seedlings before they open the true leaves The roots of the seedlings without the true leaves almost have no fibrous roots In overcast days or in the evening, use hard bamboo to gently pick out (with mud as much as possible), pick (a handful) and plant at will, water after planting, and use extremely light human urine or urea point to pour fertilizer once more after 7-10 days 2 In the whole seedling stage, spraying should be used to control locusts and the subsequently attracted pests such as the gyptids and longicorn Bordeaux solution can prevent bacterial wilt, but it is useless to spray Bordeaux solution after the seedlings get bacterial wilt It should be irrigated with kueling and carbendazim At the same time, it is necessary to hoe the surface shallowly to increase the ground temperature and water more light fertilizer to enhance the soil fertility The leaf of downy mildew has black spot, its back is like frost and leaves fall; sclerotinia disease shows rotten root and stem In the air temperature of about 20 ℃, it is rainy for a long time, with high humidity, insufficient soil power, and infected by the disease source of Eucommia ulmoides young forest nearby, the above diseases are also easy to get in the nursery It can be sprayed or poured with Diane ammonium (zinc), Diane manganese zinc and carbendazim Loosen the soil to increase the ground temperature, sprinkle 1:4 plant ash and quicklime powder on the root of the plant, bury or burn the diseased plant, and pay attention to the field drainage 3 Pull out the grass when the seedlings are unearthed to prevent grass shortage; loosen the soil and weed after 4 leaves Early hoeing can improve the ground temperature and fight against the source of disease At the beginning of 1-2 times, the soil should be lightly loosened and hoed 4 times in the whole seedling period In August, in the high temperature period, only the grass is pulled but not the soil 4 Fertilization at seedling stage should be "eat less and eat more" Farmyard manure and compound fertilizer should be the best, fertilization should be light, and it is appropriate to irrigate sparsely after loosening soil every time Ammonium bicarbonate should not be used to prevent fertilizer damage When the height of the seedlings is 30 cm, they can urinate in rainy days, with the dosage of 4-5 kg per mu After the seedling height is 40 cm, urea can be lightly sprinkled once every 15-20 days The seedlings of Eucommia ulmoides grow rapidly in autumn, and the fertilizer keeps up with the growth of Eucommia ulmoides The seedlings can grow up to 100-110cm high in the same year, and then be cultivated The high-yield cultivation technology of Eucommia ulmoides Oliv Eucommia ulmoides Oliv Is a special medicinal material in China Its bark is used as medicine It has the functions of nourishing the liver and kidney, strengthening the muscles and bones and reducing blood pressure Its high-yield cultivation technology is as follows: 1 Select the land, prepare the land and choose the neutral loam or sandy loam with sunny terrain, fertile soil and good drainage Before planting, apply enough base fertilizer, deep plough and rake fine 2 Seedling raising 2.1 When selecting the mother tree and seed treatment for seed collection, the trees with more than 15 years old and sunny growth on the fertile soil should be selected as the mother trees, and the mature and full seeds of that year should be collected Soak the seeds in 60 ℃ water, cool down naturally, keep at 20 ℃, soak for 2-3 days When the seeds expand and the peel softens, take them out, mix in the plant ash and dry soil, and mix them for sowing 2.2 Eucommia is sown in the north of Qinhuai River and the high mountain area of subtropics from February to March; in the south of Qinhuai River, it is sown as it is picked and sown in rows, with a row spacing of 23-26cm and a depth of 3cm, with a seed amount of 4-5kg per mu It is sown with a straw curtain and watered 2.3 nursery management in addition to conventional measures, the nursery management should pay special attention to keep the soil moist, and pay attention to the time seedlings, seedlings, high temperature and drought irrigation 3 The transplanting and transplanting shall be carried out in spring The transplanting land shall be ploughed in an all-round way A pit with a diameter of about 70 cm and a depth of 70 cm shall be dug Farmyard manure shall be applied in the pit The amount of fertilizer applied per mu is 1000-1500 kg, and the spacing between plants and rows is 1.50 m × 2 M the disease-free seedlings with a height of about 100 cm shall be selected and transplanted at the same time 4 Field management 4.1 the number of times of weeding and transplanting is generally 3-4 times in the same year, which can be reduced appropriately later, and the weeds in the field can be removed in combination with the medium tillage 4.2 apply farmyard manure once a year before sprouting and after defoliation in spring, and apply manure of 2000-2500 kg per mu 4.3 the frequency of irrigation and irrigation shall be determined according to the local climate conditions For areas with precipitation greater than 600mm, irrigation is not required in normal years For areas with precipitation less than 600mm, irrigation shall be conducted 3-4 times Before germination, in the growth period and dormancy period of new shoots, once in 3-5 days before peeling Irrigation shall be conducted in combination with topdressing 4.4 the disease control of Eucommia ulmoides mainly includes sudden onset disease, leaf blight and root rot in the early stage of the disease, spray 65% zineb WP 500-600 times, once every 25 days, use 70% methyltobujin WP for root rot, dig 3-5 circular ditches 30-45cm wide and 50-70cm deep, 100-150 G / plant, applied to the periphery of the crown 5 Harvesting and processing 5.1 Eucommia ulmoides Oliv can be peeled only after it has been planted for more than 10-15 years, and the peeling is carried out from April to June Use a saw to saw a circular opening on the ground to the depth of xylem, and then saw the second circular opening at an interval of 80 cm upward Cut all the openings between the two circular openings, and peel the edges gently at the longitudinal incision of the bamboo blade knife to separate the bark from the xylem 5.2 after the bark is peeled and scalded with boiling water, it shall be placed on the flat ground under the wheat straw mat layer by layer, covered with wood plate, and the weight shall be compacted The surrounding area shall be covered with grass to make it sweat For about 7 days, the endothelium shall be dark purple brown Take it out and dry in the sun, and scrape off the thick skin Xinchang Chengguan dividend CNC Manufacturing Factory Company: /cn: Fax: customer service:
