Rosa roxburghii, alias Kinashi and Tianci pear, is a perennial deciduous shrub in Rosaceae. It is called Rosa roxburghii because its fruit looks like a pear and its surface is covered with small thorns. Rosa roxburghii has high medicinal value, nutritional value and ornamental value, and has broad development prospects.

(1) medicinal. The flowers, leaves, fruits and seeds of Rosa roxburghii can be used as medicine, which has the effects of invigorating stomach, promoting digestion, nourishing and stopping diarrhea. Especially Rosa roxburghii is rich in anti-aging, anti-radiation and anti-cancer active substances-superoxide dismutase.

SOD (abbreviated as SOD) has a good preventive effect on cardiovascular and digestive diseases and various tumors. At present, 3p- sitosterol, which is effective in treating early cervical cancer and skin cancer, has also been extracted from Rosa roxburghii pulp.

(2) High vitamin content. Rosa roxburghii is the first-class raw material for processing health food. Ripe Rosa roxburghii is delicious, sweet and sour, and has a particularly high vitamin content. According to the determination,100g of Rosa roxburghii fresh fruit contains vitamin C 1.8- 2.5, which is 5- 10 times higher than that of kiwifruit, and contains 2.8g of vitamin D and 2.4-3.6mg of vitamin E. Rosa roxburghii also contains other vitamins and trace elements. Rosa roxburghii fruit can be processed into fruit juice, fruit wine, beverage, preserved fruit, jam, etc.

(3) Rosa roxburghii is a good tree species for greening environment. The thorn pear tree is not high, with dense branches and good greening and covering effect. It has many patterns, large flowers, long flowering period, green and glittering fruit and special fragrance when it matures. Rosa roxburghii can also be planted in gardens and green spaces, and is also a good choice for planting hedges, thorn hedges and flower hedges.

(1) feature. The plant height is about 1.5 meters, and the crown is mostly clustered or spreading, with odd pinnate compound leaves. Flowers began to bloom in late May, with white, pink and crimson petals. The flowering period lasts for half a month, and the fruit matures from the end of August to the beginning of September. The fruit is oblate, green when immature and yellow when mature, containing 10~50 seeds. The fruit per plant 10~29 kg, 1 1 entered the defoliation stage. Rosa roxburghii likes warm and humid climate, with annual average temperature 12- 16℃ and annual rainfall1000 mm. The requirements for soil are not strict, and acidic or slightly acidic soil with pH value of 5.5 ~ 7 is better.

(2) Seedling propagation. There are two ways: sowing and cutting.

(1) seed propagation. There are spring sowing and autumn sowing. Rosa roxburghii seeds have no obvious dormancy period, and the germination rate and emergence rate can reach more than 90% if they are sown immediately after the seeds mature in autumn. Sow in autumn, collect the seeds after the fruit ripens in the first half of September, immediately sow in the seedbed, and emerge in the second half of June. 10. Transplant the nursery in March of the following year and leave the nursery at the end of the year. But it needs to be covered with plastic film to prevent freezing in cold areas in winter. Spring sowing is suitable for late February to early March, seedling emergence in early April, and transplanting to nursery from late May to early June. Soak the seeds in 50-60~C warm water 12-24 hours the day before sowing, and then wash and sow, which can germinate 5 days earlier and improve the germination rate.

② cutting. It can be done in spring, summer and autumn. When sowing in spring, the 1 annual branches pruned in winter are cut into 10~ 12 cm long, with the lower end obliquely cut at the bud and the upper end obliquely cut at the bud with 1 cm. 100 1 tied up and hidden in wet sand. In the first half of February of the following year, the plant spacing is 9x24, the buds are exposed 1, and the cuttings are covered with soil. It germinated in mid-March, and the survival rate was over 90%. Cutting in summer and autumn, taking 1-3-year-old branches and treating the base of cuttings with ABT rooting powder, the rooting survival rate is 100%.

(3) Colonization. The suitable period before planting is from late February to early February of the following year. Soil preparation and fertilization should be carried out before planting. Carry out hole planting in Pingyuan, and dig fixed planting holes at the row spacing of 1.5x2 meters, with the length, width and depth of 50cm respectively. To build a garden in a low mountain, a horizontal belt should be built according to the contour line, with a spacing of 1. 5-2 meters, bandwidth 1- 1.5 meters, planting holes shall be dug at the spacing of 1.5 meters. Before planting, compost100 ~150kg was applied to each hole, and 250g of calcium magnesium phosphate fertilizer was mixed with soil. When planting, the roots should be elongated, the soil should be firmly covered and the planting water should be poured. After the seedlings survive, we should pay attention to timely intertillage weeding and fertilization, and water them in time to fight drought when it is dry.

(4) plastic trimming. Keep the tree height at 1.5-2m, the crown width at 1.5m or so, and there are 5-8 main branches in the whole cluster, which are interlaced with bearing mother branches. At the initial stage of planting, let it grow, promote fruit and crown, then sparse the branches that are too dense, drooping and too long, and cultivate the fruiting mother branches through pruning in winter and summer to achieve the purpose of three-dimensional fruiting.

(5) pest control. Common diseases and insect pests of Rosa roxburghii include powdery mildew, aphid, thorn moth, debt-dodging moth, whitefly, moth eater and so on. Powdery mildew occurs in spring and autumn, so triadimefon should be sprayed in early June, and the control effect can reach 74%-88%. Aphids mainly harm new shoots, so spraying 80% dichlorvos 2000 times is suitable, and the control effect is good. In addition, it is also effective against leafhoppers, spiny moths, leaf curl moths and small ape leaf worms. Whitefly parasitizes on the back of leaves. When pests occur from May to August, 2000 times of isocarbophos can be used for control. Spraying with 6,000 times of 2.5% triamcinolone acetonide solution twice from early July to August can control fruit eaters.

(6) harvesting and drying. From the end of August to September, the fruits are maturing one after another, so it is advisable to pick them in batches when the fruits are dark yellow and fragrant. When picking, put it down gently to prevent pressure, and sell it immediately after picking. Dried fruits are easy to process and can be dried or dried. The storage time of dried products is about 1 year. Before storage, each ton of dried products should be smoked with 2 kilograms of sulfur powder for 2 hours, then packed in gunny bags and stored in film bags. After 1 year, the loss of vitamin C was only 2.85%. Without fumigation, the loss of vitamin C will be as high as 80% after 1 year.
