Calcium Fruit

Calcium Fruit

A deciduous shrub of the genus Prunus in the rose family, 1.5 m tall. Bark grayish brown, branchlets puberulent; 

The leaves intergrow round or elliptic lanceolate; Flowers and leaves open at the same time, solitary or concurrent, 

petals white or pink; Drupes subglobular, bright red or orange when ripe. Flowering in April to May, fruit in May to June.

Calcium fruit originated in China, distributed in Hebei, Liaoning, Jilin, Heilongjiang, Inner Mongolia, Henan, Shandong, 

Jiangsu, Sichuan and other places, in Europe, North America, South Africa is also widely cultivated. It is often found on 

sunny slopes, stone crevices and roadside bushes. Calcium fruit has strong adaptability, can resist cold, drought and barren, 

salt and alkali. The main mode of propagation is sowing or branching.

According to the records of Shennong's Herbal Classic, the seed of calcium fruit, Yu Li Ren, can be used as medicine, with bitter, 

sweet and smooth taste. Spleen, large intestine, small intestine channel; It is used to moisten dry and slippery intestine, lower Qi 

and water, food accumulation and qi stagnation, abdominal distention and constipation, edema, beriberi and unfavorable urination. 

Calcium fruit is delicious and nutrient-rich, and is a high quality raw material for juice processing. Its short plants, bright red fruits, 

dark green leaves, can also be used for bonsai or garden greening. Calcium fruit can also be used for soil and water conservation.

Morphological characteristics

Calcium fruit is a shrubby plant, 0.4-1.5 m tall. Branchlets grayish brown or tan, pubescent. Winter buds ovate, sparsely pubescent 

or somewhat glabrous. Leaf blade oblong-elliptic or oblong-oblong-lanceolate, 2.5-5 cm long, 1-2 cm wide, broadest above middle,

 apex acute or breviacuminate, base cuneate, margin simple or double serrated, dark green above, glabrous, light green below, 

glabrous or sparsely pubescent, lateral veins 6-8 pairs; Petiole 2-4 mm long, glabrous or sparsely pubescent; Stipules linear, 5-6 mm

 long, with glands on either side.

Flowers solitary or 2-3 clusters, flowers and leaves open together; Pedicels 5-10 mm long, sparsely pubescent; Calyx tube nearly 

equal in length and width, ca. 3 mm, outside sparsely puberulent, sepals triangular-ovate, apex acute or obtuse; Petals white or pink,

 oblong or obovate; Stamens 30-35; Style subequal to stamen, glabrous.

Drupes subglobular when ripe, red or purplish-red, 1.5-1.8 cm in diameter; The nuclear surface is not ribbed except on both sides of

 the back. Flowering period from April to May, fruit period from June to October.

Habitat of origin

Calcium fruit originated in China, distributed in Hebei, Liaoning, Jilin, Heilongjiang, Inner Mongolia, Henan, Shandong, Jiangsu, 

Sichuan and other places, in Europe, North America, South Africa is also widely cultivated. It is often found on sunny slopes, stone 

crevices and roadside bushes. The distribution of calcium fruit is little or no in the high vertical mountains and shady slopes with 

great changes, while the distribution is most in the gentle slopes, hilly areas and terraces. There is no obvious difference between 

the distribution and the altitude, and it is generally distributed at the altitude of 300-1800 meters.

Growth habit

Calcium fruit has strong adaptability, can resist cold, drought, barren, salt and alkali, like more humid environment, in fertile sandy 

loam or light clay loam planting is appropriate. It has special drought resistance and is suitable for planting in arid areas. It can avoid 

drought and store water in rainy season. In the dry spring, calcium fruit not only has higher leaf water content, but also strong water 

retention. Calcium fruit leaves are small and thick, although the stomata density is large, but the stomata is small, and the water loss 

is less. In the dry season, the growth rate of the above-ground part slows down, and the base of the soil plant produces a large 

number of basic buds, which do not germinate. When the rainfall occurs, the basic buds can form underground stems, expand in the 

soil, form rhizoids or sprout out of the surface to form new plants. This physiological characteristic is the intrinsic factor of calcium 

fruit drought resistance.

Mode of reproduction

The main propagation mode of calcium fruit is sowing or branching.

Cultivation technique

Select the land to prepare the land

Calcium fruit is suitable for planting in places with sufficient light and certain shade. The soil should ensure sufficient fertility, rich 

humus and certain permeability, so that the soil can effectively ensure the growth of calcium fruit. After choosing the land, pay 

attention to the preparation work, and turn it about 30 cm deep. Then apply sufficient bottom fertilizer in the deep turning, and 

fully mix it with the soil to improve the fertility of the soil. Then to do the ridge, the ridge will be pressed tightly, improve the soil's 

ability to retain water and fertilizer, promote the growth of plum, increase yield.

Timely planting

The planting time of calcium fruit is generally carried out after falling leaves, or after the soil temperature rises and thaws in the 

spring. If it is not with soil seedlings, then spring and autumn can be carried out. When planting in the spring, it is best to do it 

before the buds are expanded and mature. Planting time has a great relationship with the subsequent growth ability of calcium 

fruit. When we are planting, we also need to pay attention to controlling the planting density, and it is most appropriate to control 

the spacing between the plants at about 50 cm, which can prevent the planting from being too dense, and the plants affect each 

other's growth, and can improve the utilization rate of land resources, which is convenient for planting management.

Water and fertilizer management

Although the barren resistance of calcium fruit is strong, the yield of artificial cultivation is relatively high. To ensure that there is 

sufficient nutritional water to improve the yield of calcium fruit. Therefore, when we plant calcium fruit, we should topdressing 

about three times a year, generally at flowering, expansion and after harvesting. Pay attention to the amount and type of fertilizer 

to prevent improper fertilization resulting in fertilizer damage to calcium fruit. Then pay attention to observe the water content of 

the soil, prevent insufficient water from affecting the growth of calcium fruit, and water frequently. However, water should not be 

too much, too much water should be drained in time to avoid water retting and reduce production.

Medicinal value

According to the records of Shennong's Herbal Classic, the seed of calcium fruit, Yu Li Ren, can be used as medicine, with bitter, 

sweet and smooth taste. Spleen, large intestine, small intestine channel; It is used to moisten dry and slippery intestine, lower Qi 

and water, food accumulation and qi stagnation, abdominal distention and constipation, edema, beriberi and unfavorable urination.
