How to select goji berry seeds? What are the seedling raising methods?

Goji berry belongs to the Solanaceae family. It grows in large quantities in the northern regions of our country, has very strong cold resistance, and is drought tolerant. In areas with severe waterlogging, root rot easily occurs. It prefers loose, fertile sandy soil and a growing environment with ample light. So how should goji berry seeds be selected? What are the seedling raising methods? Let's take a look together below.

1. How to select goji berry seeds?

In the planting area, select robust plants with large red fruit, free of pests and diseases, and more than 6 years old as mother plants for seed collection. From June to November, when the fruit turns red, pick it promptly. Soak the picked fruit in 30-35°C warm water for 24 hours, remove and rub them, then rinse out the seeds in clean water. Remove the pulp and skin, take out the mature, plump seeds that sink to the bottom, and sow after drying. If not sowing immediately, mix 1 part seeds with 3 parts wet sand evenly, place in a wooden box, and stratify at 20°C indoors to promote germination. The following spring, when 30-50% of the seeds have cracked and shown white, take them out and sow.

1. Goji berry cutting propagation

In spring before the plants begin to sprout, select plants with large fruit, high yield, and good quality, cut 1-year-old branches with a diameter of 0.5 cm, cut them into 15-20 cm long cuttings, quickly dip the lower end of the cut in 0.05% rooting powder or 0.05-0.1% indolebutyric acid solution for 10-15 seconds, and insert after drying. When inserting, open furrows on the prepared seedbed surface at a row spacing of 40 cm, with a furrow depth of 15-20 cm, insert at a plant spacing of 10 cm, with the cuttings exposed about 1 cm above the soil surface. After insertion, build a shade frame, keep the seedbed moist frequently, strengthen cultivation and weeding, and apply appropriate topdressing. When the seedlings are 80 cm tall, they can be lifted for field planting.

2. Goji berry division propagation

Division and transplanting are mostly carried out in early to mid-March and April. Directly take root suckers from the goji berry orchard for transplanting. After digging up clustered plants, cut off most of the branches, divide and plant them, water immediately, and keep the soil moist frequently. They survive very easily and can bloom and bear fruit in the same year. Goji berry division cultivation saves labor, but the quality of the variety is not easy to distinguish. To avoid the above shortcomings, you can cut and transplant the tiller seedlings growing on the horizontal roots at the lower part of the mother plant's root crown or within 3-7 cm from the mother plant.

3. Seed seedling raising

Sowing can be done in spring, summer, and autumn, with sowing in late March in spring being the best. On the prepared seedling bed, open sowing furrows horizontally at a row spacing of about 25 cm, with a furrow depth of 2-3 cm and a sowing width of 5 cm, then evenly scatter the seeds into the furrows, cover with fine soil after sowing, press lightly, and cover the bed surface with grass to keep warm and moist. The seed rate per mu is 150-200 grams.

Water frequently after sowing to keep the bed soil moist, so as to facilitate seed germination, emergence, and seedling growth. After the seedlings emerge, remove the grass covering the bed, then carry out cultivation and weeding 4-5 times, and thin the seedlings in combination with cultivation and weeding. The first time, when the seedlings are 5 cm tall, pull out weak seedlings and keep seedlings at 5-6 cm. The second time, in early to mid-July, remove the weak and keep the strong, and set the seedlings at 10-15 cm. While thinning and setting seedlings, apply 1000-1500 kg of dilute human and livestock manure per 667 square meters each time to promote robust seedling growth. When the seedlings grow to 30 cm tall, promptly remove the side branches growing from the base of the seedlings. When the seedlings are 60 cm tall, top them to accelerate the thick and strong growth of the main trunk and main side branches. Seedlings raised in spring can be lifted for planting after autumn. Seedlings raised in summer and autumn should be irrigated once with sealing ice water in winter and lifted for planting after autumn the following year.

The above is an introduction to goji berry. There are many seedling raising methods for goji berry. Farmers planting goji berry should choose suitable seedling raising methods according to their own actual conditions and local climate conditions, etc., to achieve the goal of high yield.
