Introduction to propagation methods and seedling raising techniques of Lycium barbarum

Lycium barbarum is a multi-branched shrub plant of the genus Lycium in Solanaceae. it is often born on hillsides, wastelands, hills, saline lands, roadsides and houses beside the village. gardens can be used as hedges, stakes, potted plants and shrubs for soil and water conservation. its fruit wolfberry and Qiongzhen Ganoderma lucidum, Changbai Mountain Ginseng, Dong E E Jiao are called the four treasures of traditional Chinese medicine. Let's take a look at the cultivation techniques of Chinese wolfberry seedlings.

Cutting culture of Lycium barbarum

Before the plants germinated at the end of spring, the plants with large fruit, high yield and good quality were selected, and the annual branches up to 0.5 cm in diameter were cut into cuttings 15 cm long. The lower end of the incision was quickly dipped with 0.05% rooting powder or 0.05-0.1% dole butyric acid solution for 10 minutes and 15 seconds, and then cut after drying. When cutting, trench on the border surface of the whole seedling land according to the row spacing of 40 cm, the ditch depth of 15 cm to 20 cm, the plant spacing of 10 cm, and the cuttings exposed to the soil surface of about 1 cm. After planting, set up a shed for shade, often keep the seedbed moist, and strengthen ploughing and weeding, appropriate topdressing, when the seedling height is 80 cm, it can be planted out of the nursery.

Separate cultivation of Lycium barbarum

Ramet transplanting is more than March to early April, directly control the root tiller seedlings in the Lycium barbarum orchard to transplant, dig up the tufted plants, cut off most of the branches, plant them, immediately water them, and often keep the soil moist, so it is easy to survive and blossom and bear fruit in the same year. The separate cultivation of Lycium barbarum is more labor-saving, but the quality of the variety is not easy to distinguish. In order to avoid the above shortcomings, the seedlings growing on the lower part of the rhizome of the mother plant or on the horizontal root within 3 cm from the mother plant can be cut off for transplanting.

Seed breeding of Lycium barbarum L.

The main results are as follows: 1. Seed selection and seed collection: in the planting area, the growth is robust, the fruit is red, and there are no diseases and insect pests. The plant with more than 6 years old is used as the mother plant, and when the fruit is red from June to November, it should be picked in time. Soak the picked fruit in 30-35 ℃ warm water for 24 hours, remove and knead, and rinse the seeds in clean water. Remove the pulp and peel, take out the ripe and full seeds that have sunk to the bottom of the water, dry them and then sow them. If you do not sow immediately, mix 1 seed with 3 parts of wet sand evenly, put it in a wooden box and place it in a 20 ℃ indoor layer to accelerate budding. in the following spring, when there are 30-50% seeds exposed, take out and sow.

2. Sowing in time: sowing can be carried out in spring, summer and autumn, and it is best to sow in late March in spring. On the whole seedling border, the seed ditch was planted horizontally according to the row spacing of about 25 cm, the ditch depth was 2 cm 3 cm, and the sowing width was 5 cm. Then the seeds were evenly scattered into the ditch, covered with fine soil after sowing, slightly compacted, and covered with grass for heat preservation and moisturization. the amount of seeds per mu was 150 to 200 grams.

3. Seedling management: often watering after sowing to keep the border soil moist. To facilitate seed germination, seedling emergence and seedling growth. After the seedlings were unearthed, the weeds on the border were removed, and then the weeding was carried out for 4 or 5 times, and then the seedlings were removed in combination with weeding. The weak seedlings were pulled out when the seedlings were 5 cm high, and the seedlings were retained at 5 cm in height. The second time in the first and middle of July, the weak and strong seedlings were removed, and the seedlings were fixed according to 10 cm to 15 cm. At the same time, 1000-1500 kg of sparse human and animal feces were applied every 667 square meters to promote the growth of seedlings. When the seedling grows to 30 cm high, the lateral branches of the seedling base should be removed in time, and the top should be carried out when the seedling is 60 cm high, so as to accelerate the growth of the trunk and main lateral branches. The seedlings in spring can be planted in the nursery after autumn, the seedlings can be irrigated with frozen water once in winter in summer and autumn, and planted in the nursery after autumn the following year.

Introduction to cultivation techniques of Lycium barbarum

Introduction: since ancient times, people have paid attention to health and nourishment, traditional Chinese medicine ingredients can regulate the various mechanisms of the body, so that each part of the function to adjust and unify, to achieve the most perfect state of body and mind. Our common practical ones for recuperating body and mind are Tremella fuciformis, lotus seed and Chinese wolfberry. It can not only cool off the fire, but also nourish yin and replenish deficiency. Among these nourishing items, the high-quality ones are expensive, so many people are willing to grow their own, and some business-minded people find business opportunities to plant Chinese wolfberry trees. The editor will introduce the planting method of Chinese wolfberry tree to you.

1. Direct seeding afforestation: strip sowing or hole sowing can be adopted and sown from late March to April after soil thawing in spring, the earlier the better. The sowing depth is 1ml / 3cm. In the seedling stage, the aboveground part of Chinese wolfberry is low, and it is easy to be eaten by livestock and uprooted by roots, so grazing must be banned after sowing.

two。 Seedling transplant: seedling can be raised in four seasons, but it is better in spring and autumn.

3. Cuttings and striping: Lycium barbarum root sprouting is very strong. Cuttings are easy to survive in spring and autumn. After soaking the branches of Chinese wolfberry growing on the barren slope for 3 days, cut them into cuttings with a thickness of O.5mi 1cm and a length of 30Mel 50cm.

4. Tillering propagation: in order to increase the coverage area, the trunk is cut off above the neck of the 2-year-old Chinese wolfberry root, and many young branches can germinate in the second year, or the main root of Chinese wolfberry can be truncated, that is, many young branches germinate from both ends of the truncated main root to increase the coverage. Spring is the best cut-off time.

[seed propagation]: excellent varieties can be selected to pick mature fruits with large fruit, bright color and no disease and insect spots. After picking in summer, soak the seeds in 30-60 ℃ warm water, rub the seeds, wash them, and dry them. Stop well with wet sand (1:3) before sowing, germinate at 20 ℃ at room temperature, wait for 30% when the seeds are white or soak the seeds in clean water for one day and night, then sow the seeds. It can be sown in spring, summer and autumn, mainly in spring. Spring sowing in late March to early April, according to the row spacing 40cm trench sowing, deep 1.5-3cm, covering soil 1-3cm, after the seedlings are unearthed, according to soil moisture, pay attention to irrigation. Seedling height 1.5-3cm, loosen the soil and weed once, and then loosen the soil and weed once every 20-30 days. The height of seedlings was 6-9cm, the distance between seedlings was 12-15cm, and the number of seedlings per 1hm2 was 150000-180000. Combined with irrigation, topdressing fertilizer for 3 times in May, June and July, in order to ensure seedling growth, the lateral buds of young plants off the ground should be removed in time, and the lateral buds should be removed when the seedling height is 60cm, so as to accelerate the growth of trunk and upper lateral branches. When the root is thick and 0.7cm, it can be transplanted out of the nursery.

The price of high-quality Chinese wolfberry on the market is on the high side, and Chinese wolfberry is the best thing to tonify the body. if you cultivate Chinese wolfberry, you can not only eat Chinese wolfberry for a long time, but also benefit relatives and friends. Chinese wolfberry can not only be washed and drunk, but also can be used as a fresh seasoning in cooking. At the same time, it can be eaten and tasted. However, the planting technology of Chinese wolfberry tree is also complicated, which needs to go through the process of transplanting, cutting and propagation. In the process of planting, it is necessary to consult experts and constantly maintain the seedlings in order to plant luxuriant Chinese wolfberry trees.

Techniques of sowing and raising seedlings of Lycium barbarum

Seed sowing and breeding, that is, sexual reproduction. It uses seeds to reproduce seedlings. The advantage of this method is that it can produce a large number of seedlings in a short time, meet the urgent need for seedlings in production, and is low in cost and easy to master. The disadvantage is that the variability of the production seedlings is great, the excellent characters of the mother tree can not be maintained, and the fruit is late and the quality is poor. However, considering the need of a large number of seedlings in production at present, although this method has some shortcomings, it still has certain application value.

Seed preparation: there are many varieties of Lycium barbarum, but Ningqi l, Ningqi 2 and hemp leaf are better. Therefore, the large fruits of the above excellent varieties should be selected for seed production. Small fruits with mixed quality should not be used for seed production, so as not to reduce the seed quality. Making seeds: making seeds from Chinese wolfberry fruit can be divided into the following steps: ① fruit soaking. If you use dried fruit to produce seeds, you should soak the dried fruit in water until the pericarp is swollen and rotten, but if you use fresh fruit to produce seeds, you don't have to soak. ② fruit is crushed. Crush the swollen fruit or fresh fruit so that the seed is completely separated from the pulp. ③ washing. After crushing the fruit, put an appropriate amount of water to wash, pour out water juice, peel and suspended empty seeds and other impurities, after several times of washing, sink in the bottom of the basin are full seeds. ④ seeds are dried. Spread out the full seeds and dry them. After drying, store them in a cool, dry place. Generally speaking, about 0.1 kg of seeds can be produced per kilogram of dried fruit. What is the germination rate of seeds? 4. How to reflect and reflect? Stop? Round ash? Cap 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 / 4 Sowing time: Chinese wolfberry can be sowed in spring, summer and autumn, but more in spring in production. After sowing in spring, under the conditions of suitable temperature and humidity, the seeds germinated and unearthed, and the seedlings also had a longer growth period, which could be planted in the nursery in autumn or the following spring. The seeds of Lycium barbarum are small, with a thousand seeds weighing about 1 gram, and it takes only 0.2 kg for every 667 square meters to sow. Sowing method: divided into water sowing method and dry sowing method. ① water sowing method. When sowing, mix the seeds with 10 times fine sandy soil, then use a hoe to open a 0.3 cm 0.5 cm wide sowing ditch on the prepared nursery with a row spacing of 40 cm, and sow along the ditch. After sowing, cover the soil with a thickness of about 0.3ft 0.5 cm, or use your feet slightly without covering the soil, so that the seeds are in close contact with the soil, then irrigate once shallowly with water, and then irrigate again after 2-3 days when the surface is not wet. Regular irrigation before seed germination and soil emergence to keep the surface moist is beneficial to seed germination and seedling growth. This method has the advantages of fast sowing, neat emergence, high emergence rate and simple operation. ② dry sowing method. It is different from the water sowing method in that it covers the soil according to soil properties and soil moisture after sowing, with a thickness of 1-2 cm. Sandy soil, poor soil moisture, thicker soil cover; clay soil, good soil moisture, thinner soil cover. Do not irrigate immediately after covering the soil, if the weather is dry after sowing, the soil moisture is poor, and it does not sprout for a long time, shallow irrigation with small water can also be used to promote seed germination. In order to make the seeds emerge early after sowing, the seeds can be germinated before sowing. 1 part of the seed mixed with 10 parts of fine wet sand, mixed well and placed in a room of about 20 ℃, covered with plastic film, sprayed with water once a day to maintain a good temperature and humidity, generally sowed when half of the seeds were white (germinated). Sow seeds when the temperature and humidity are suitable in summer, and sprout and unearth a week later.
