Red raspberry plants are 2 to 3 meters tall, the young shoots have white powder and a few barbs.Leaves are simple, alternate, suborbicular, palmately 5-lobed, middle lobes rhomboid ovate, base subcordatate, margin doubly serrate, white pubescent on both veins; Petiole, stipule, stipule are linear-lanceolate; Flowers of Red raspberry are bisexual, solitary at apex of short branches, calyx persistent, calyx lobes pubescent on both sides; Stamens are numerous, filaments broad and flat; Anthers are T-shaped, pistil numerous, pilose, borne on raised rectum.

3-7, sometimes flowers on 3 flocculus, infertility branches often 5-7 lobule, long ovate or elliptic, leaflets often ovate, sometimes shallow crack, 3-8 cm long, 1.5 4.5 cm wide, apex short acuminate, base rounded, base nearly heart-shaped lobules, glabrous or hydrophobic villous, densely covered with grayish white hairs below, margin irregular coarsely serrate or double toothed; Petioles of Red raspberry are 3-6 cm long, terminal petioles ca. 1 cm long, all villous pubescent and sparsely spiny;Stipules linear, pubescent.

Pedicels and pedicels of Red raspberry are densely covered with villous pubescent hairs and needles with different density. Pedicels are 1 -- 2 cm long;Bracts linear, pubescent; Flowers of Red raspberry are 1-1.5 cm in diameter; Calyx is densely villous pubescent and unevenly spaced pin pricked outside; Sepals of Red raspberry are ovate-lanceolate, apical caudate, outer margin with gray-white tomentose, erect in fruit and fruit; Petals of Red raspberry are spatulate, pubescent or glabrous, white, with broad claws at base; Filaments are broadly oblate, longer than style; Style of Red raspberry is base and ovary densely gray-white tomentose.

Fruit of Red raspberry is subglobose, juicy, 1 -- 1.4 cm in diameter, red or orange yellow, densely tomentose; Nucleus with obvious pits. The fruit of the Red raspberry is an aggregate of Red, gold, and black, spherical, pendulous, dense grayish-white pubescent fruit grown in Europe and the United States.

Red raspberry's distribution area

Red raspberry is mainly distributed in China's Liaoning, Jilin, Inner Mongolia, Fujian, Hebei, Henan, Shandong, Shanxi, Jiangsu, Anhui, Yunnan, Zhejiang, Jiangxi, Hunan (Yanling County mountain area most), Hubei, Guangxi, Guangdong, Shaanxi, Guizhou, Sichuan, Chongqing, Gansu;Xinjiang and other regions.Japan, Siberia, Central Asia, North America, Europe are also distributed.

Red raspberry's ecological habits

Red raspberry grows in mountainous forests, thickets, or wilderness, at altitudes of 500-2000 meters.

Red raspberry growing methods

Site preparation transplanting

Selected deep soil layer, fertile loose, good drainage of the slightly acidic gentle slope, deep turn the land. Transplant according to the Red raspberry row spacing of 50 cm ×100 cm or 100 cm ×100 cm.

Field management

After transplanting of Red raspberry, plowing, weeding and topdressing 3-4 times a year. In the Red raspberry growing season timely trim plastic. For spring pruning, keep 7-9 strong branches in each cluster, and fasten them with single or double posts or hedgerows. Pruning each plant with 12-15 evenly distributed strong branches in summer, and removing the core of the retained basic branches; Autumn shears in the fruit of Red raspberry after the harvest, cut to dry branches, sick branches, weak branches, shears dense branches.When rain or drought is excessive, timely drainage and irrigation water.

Before transplanting Red raspberry, apply sufficient base fertilizer, apply farmhouse fertilizer 3-5 kg per plant. During the Red raspberry growth period, combined with loose soil weeding, application of top dressing 2-3 times a year, nitrogen fertilizer, appropriate amount of phosphorus and potassium fertilizer. Seedling fertilizer was applied in spring, flower fertilizer was applied in spring, and winter fertilizer was applied for Red raspberry in winter. 1500-2000 kg of human excrement per acre. Watering during dry periods in summer and autumn. When new branches have lateral branches, pick off the terminal bud to promote the growth of lateral branches of Red raspberry.  At the same time, pick the center of lateral branches to promote the occurrence of secondary lateral branches. With more leaves, the parent branches of the next year will be increased and the yield will be increased. Props should be placed beside each plant at the fruiting stage to prevent lodging.

In the middle of May, the fruit is 80% ripe and the calyx is harvested and packaged together.

Red raspberry's way of propagation

There are branching propagation, split propagation and seed propagation of Red raspberry. Partition propagation can be used for transplanting seedlings germination from the root stem of the mother plant. Partition propagation of Red raspberry means to dig the roots and stems in the early spring before the adventitious buds are unearthed, cut them off according to the length of 10-15 cm, insert them diagonally or bury them shallowly, keep the soil moist, so as to survive. Seed propagation of Red raspberry to pick mature fruit, wash off the fruit, with wet sand layer storage to autumn or the next spring sowing, sowing one year after the transplanting. The most practical method is to dig up the regenerative branches and plant them in winter after the leaves are all gone. Cuttage propagation of Red raspberry will be thick about 25px side root dig out, choose the root with bud, cut into about 250px root strips, in the middle of spring for cutting, dig 250px deep ditch, the root inserted diagonally into the bed, exposed a quarter of the soil, buried flat.
