Cultivation techniques of Lycium barbarum seedlings

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.
