How to choose Chinese wolfberry seeds? What are the methods of raising seedlings?

Lycium barbarum belongs to Solanaceae, which has a large number of growth in northern China, strong cold tolerance, and drought tolerance, serious waterlogging areas are prone to rotten roots, like loose and fertile sandy soil, like the growth environment with sufficient light. So how to choose the seeds of Chinese wolfberry? What are the methods of raising seedlings? Next, let's have a look with the editor.

First, how to select Chinese wolfberry seeds?

In the planting area, the plants with strong growth, red fruit and no diseases and insect pests were selected. The plants with more than 6 years old were used as the mother plant, and when the fruit was red from June to November, it was 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 germination. In the following spring, when 30-50% of the seeds are exposed, take out and sow.

Second, what are the seedling methods of Chinese wolfberry?

1. Cutting seedlings of Lycium barbarum L.

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 15-20 cm long. The lower end of the incision was quickly dipped with 0.05% rooting powder or 0.05-0.1% DBA solution for 10-15 seconds, and then cut after drying. When cutting, on the border surface of the whole nursery land, the furrow spacing is 40 cm, the ditch depth is 15-20 cm, the plant spacing is 10 cm, and the cuttings are 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.

2. Separate seedlings of Lycium barbarum L.

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, which is easy to survive, and can bloom and bear fruit in the same year. The 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 3-7 cm from the mother plant can be cut off for transplanting.

3. Seed breeding

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 2-3 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 150-200 grams.

Often water the soil after sowing to keep the 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 4-5 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 according to 5-6 cm, and the second time in the first and middle of July, the seedlings were fixed according to 10-15 cm. At the same time, 1000-1500 kg of sparse human and animal feces were applied every 667m2 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.

The above is the introduction of Chinese wolfberry, there are many seedling methods of Chinese wolfberry, farmers who grow Chinese wolfberry should choose suitable seedling methods according to their own actual situation and local climatic conditions, so as to achieve the goal of high yield.
