The cranberry can be used to produce seedlings by seedling, cuttings and dividing to expand the planting area. Due to the cuttings seedling method is simple and easy to implement, and can be early flowering and fruiting, in the production area, often use this method to produce zinnia seedlings.

1. Seedling

Seedling ground preparation: choose convenient drainage and irrigation, loose fertile, sunny sandy loam soil, deep tillage, harrowing and smoothing, made into 1.3 m wide raised beds, per acre of stable manure or soil fertilizer, fire soil 1500 kg, sifted sprinkled on the bed, mixed with the bed soil, according to the row spacing of 30 cm to open the seeding ditch, ditch depth of about 5 to 7 cm. And fully wet the seeding groove.

Seed harvesting and storage: the growth of robust, disease-free plants on the mature fruit harvesting, mixed with 2 times the moist sand, stacked indoors in a cool, ventilated place for storage, the next year in March to April to take out the seed.

Seed treatment: before sowing with a bamboo sieve to sieve the fruit from the sand, gently rubbed off the shell, raised clean, placed in 35 ~ 40 ℃ warm water soaked 12 ~ 24 hours, fished out a little dry to be sown.

Sowing method: after soaking the seeds and mixed with manure, grass ash, fire soil ash and so on, evenly spread in the furrow can be. After sowing, cover a layer of grass ash or soil fertilizer, and then cover a layer of fine sandy soil, and finally cover grass in the border to keep the soil moist, about 1 month after sowing can be seedlings. Sowing amount of 6 to 7 kilograms per acre of nursery.

Seedling management: seedling should be applied 2 to 3 times dilute human and animal fecal water, to promote strong growth of seedlings, while the nursery on the weed removal, so as not to affect the growth of seedlings. In case of drought, irrigation should be used to combat drought. Under normal conditions, spring nursery seedlings can grow to 30-40 cm high that year, and can be planted in the fall.

2. Cuttings generally in February to April or fall rainy weather cuttings. Choose sturdy, disease-free 2-3-year-old branches, cut 20-25 centimeters long, with 2-3 nodes of the cuttings. In the bed according to the row spacing 25 ~ 30 cm, plant spacing 6 ~ 8 cm will be inserted into the seedbed, into the soil depth of about 2 / 3 of the insertion, stamping the soil, watering, mulching. After insertion, special attention should be paid to drenching, and rows of plowing and weeding, fertilizer, etc., to promote plant growth. Spring cuttings can be planted in the fall of the year, fall cuttings transplanted in the spring of the second year. You can also cut the branches into 30-40 cm strips and insert them directly into the planting site.

3. planting reproduction In the spring, choose rainy weather, in the fruiting season around the plant will be budding tillers dug out with the roots, trimming off the long thick roots and part of the branches and leaves can be planted.
