It can be used as yard hedges and landscaping materials, and can also be used as roadside hedges to beautify the greening environment.

The leaves are obovate or obovate oblong, with a length of 65438 0.5-6 cm and a width of 0.5-2 cm. The apex is round or slightly concave, sometimes the apex is short, the base is wedge-shaped, the lower part is connected with the petiole, the edge is blunt and serrated, the tooth tip is bent inward, nearly the whole base, and both sides are hairless; Petiole short, glabrous or pilose when tender.

The whole flower is a compound corymbose inflorescence with a diameter of 3-4 cm. The pedicel and total pedicel are nearly hairless, and the pedicel is about 65438 0 cm long. The flower diameter is about1cm; Calyx tube campanulate, glabrous; Sepals triangular-ovate, apex obtuse; Petals are white, suborbicular, about 4 mm long and 3 mm wide; Stamens 20, filaments 3-4 mm long, medicinal yellow; Style 5, free, as long as stamens, upper part of ovary densely white pilose. The fruit is nearly spherical, about 5 mm in diameter, orange or crimson. The flowering period is March-May, and the fruiting period is August-165438+1October.

Distribution range:

It is distributed in the south of the Yellow River and the vast southwest of China. All belong to 10 species, 7 of which are made in China. Many excellent cultivated varieties have been cultivated abroad. Shaanxi, Jiangsu, Zhejiang, Fujian, Hubei, Hunan, Guangxi, Sichuan, Yunnan and Guizhou provinces.

Growing habits:

Strong light, barren resistance, drought resistance, not cold resistance; Planting in the open field south of the Yellow River requires potted plants in North China and wintering in plastic greenhouses or low-temperature greenhouses. The temperature can be as low as 0℃, and the seeds can be washed with water. The requirements for soil are not strict, and the neutral or slightly acidic loam with good drainage, moisture and looseness is better.

Multiplication method:

1. Seed: Pyracantha fortuneana fruit 5438+00 ripens in June, and can be stored in the tree until February of the following year. It is appropriate to collect seeds from June 5438+00 to June 5438+02. Remove the pulp in time after harvest, wash the seeds and dry them for later use. It is better to sow pyracantha in autumn. Before sowing, seeds can be treated with gibberellin with a concentration of two ten thousandths. On the sorted seedbed, a long ditch with a row spacing of 20-30 cm and a depth of 5 cm is opened, and the sowing ditch is paved with 3 cm of soil.

Step 2 cut

1 ~ 2-year-old branches were cut into cuttings with the length of 12 ~ 15 cm, and the lower end was horse-ear-shaped. Make a small ditch with a depth of 10 cm on the sorting bed, place cuttings at an oblique angle of 30 degrees at the edge of the ditch with a spacing of 10 cm, and expose the upper part of the bed for 2 ~ 5 cm.
