Lady Banks' Rose, scientific name Rosa banksiae, is the generic name of the composite plant Cloud Lady Banks' Rose and Chuan Lady Banks' Rose. Lady Banks' rose is distributed in Sichuan, Yunnan, Xizang and other places in mainland China, mostly growing in alpine grassland and shrubs. It is a wild plant, but has not been artificially introduced and cultivated.The roots of both plants are important Chinese herbs.
Lady Banks' Rose (Rosa banksiae) is a small climbing shrub, up to 6 meters high; Branchlets are cylindrical, glabrous, with short prickles; The prickles on the old branches are larger, hard, and sometimes without prickles after cultivation.
Lady Banks' Rose (Rosa banksiae) has 3-5 leaflets, sparse 7, with petiole 4-6 cm long; Leaf blade is elliptic ovate-ovate or oblong-lanceolate, 2-5 cm long, 8-18 mm wide, apex acute or slightly obtuse, base suborbicular or broadly cuneate, margin appressed serrulate, glabrous above, dark green below, midrib protruding, pilose along veins; Petioles and axles of Lady Banks' Rose are sparsely pubescent and scattered prickles; Stipules are linear-lanceolate, membranous, free, caducous.
Flowers of Lady Banks' Rose (Rosa banksiae) are small, many into umbels, 1.5-2.5 cm in diameter; Pedicels of Lady Banks' Rose are 2-3 cm long, glabrous; Sepals are ovate, apex long acuminate, entire, outer sides of calyx tube and sepals glabrous, inner surfaces white pilose; Petals are double to semi double, white, obovate, apex rounded, base cuneate; Lady Banks' Rose has many carpels, styles free, densely pilose, much shorter than stamens.
Lady Banks' Rose (Rosa banksiae) likes warm, wet and sunny environments, and is resistant to cold and semi-shade, and is afraid of waterlogging. The ground can be planted in the sun, without water, so the soil requirements are not strict, but in the loose fertile, good drainage soil growth. Lady Banks' Rose has a strong germination force, resistant to pruning.
Lady banks' rose is made in Sichuan, Yunnan, China, raw stream side, roadside or hillside thickets, 500-1300 meters above sea level. Cultivated throughout the country.
Nutrient soil, the preparation of nutrient soil should pay attention to drainage for Lady banks' rose (Rosa banksiae), ventilation and a variety of nutrient collocation.Its proportion is Garden soil: leaf rot soil: rice chaff ash = 5:3:2. Every year before and after the winter suitable for turning over the basin, root, soil, year by year to increase the diameter of the basin, the clay pot is better.
Watering: depending on the season, the winter dormant period to keep the soil moist, dry on the line. Spring branches before hair, branches and leaves grow, appropriate to increase the amount of water, water morning and evening 1 times a day. In Lady banks' rose growing busy season and flowering period need to increase watering quantity, summer high temperature, the evaporation quantity of water increases, the plant is in weak and half dormant state, most avoid dry dehydrate, every morning and evening each irrigate water, avoid sunshine exposure. When high temperature watering, every watering should have a small amount of water oozing from the bottom of the basin, that has been watered thoroughly, do not splash water on the leaf when watering, prevent disease.
Fertilization: Lady banks' rose (Rosa banksiae) like fertilizer, fertilizer based on delayed organic fertilizer, such as rotten manure, cow dung, chicken dung, bean cake, oil residue, etc. Add liquid fertilizer water every half a month, can often protect leaf hypertrophy, dark green luster. Early spring before germination, can apply a thicker liquid fertilizer, pay attention to not fertilization in the flowering period, summer after the Lady banks' rose wither can apply liquid fertilizer again, in autumn between the fourth or fifth axillary buds will be sent again when the medium liquid fertilizer, winter dormant application of decompose organic fertilizer overwinter.
Pruning: A full pruning must be done after the first flowering of each season. General appropriate is gentle pruning, cut the residual Lady banks' rose that opens in time and delicate, cross, overlapping branch, leave stout, young branch from the base rises to leave only 3-6 cm, leave outside side bud, pruning becomes natural open heart form, make plant form is beautiful, extend flowering period.In addition, potted roses to choose low flowers and rich aroma varieties.
Lady banks' rose (Rosa banksiae) space for 50-100 cm, according to the size and needs of the seedling. In addition, rose cultivation must be sunny, dry and ventilated, good drainage, rich in organic matter of sandy soil.
Watering: planted Lady banks' rose (Rosa banksiae) mainly pay attention to the summer drought when watering enough water, especially pregnant period and flowering period must ensure enough water, but also pay attention to the rainy season and do not water.
Fertilization: winter tillage can be applied to human excrement or sprinkle with decaying organic fertilizer, and then turned into the soil, rose growth period to frequently apply fertilizer, Lady banks' rose wither after applying top dressing 1-2 times of quick-effect fertilizer. High temperature and drought should be applied to thin fertilizer, the last fertilizer before winter, before fertilization should also pay attention to remove weeds in time.
Pruning: summer pruning of roses is mainly to cut off the grafted stock of the bud and xue flowers, after flowers with leaves to cut off the residual flowers and sparse to the redundant buds of Lady banks' rose, reduce the consumption of nutrients to create good conditions for the next flowering.In order to make the plant beautiful, long branches can be cut to 1/3 or half, branches cut 1/3, in the upper leaf 1 cm oblique cut, if the pruning is too light, rose plants will be longer and higher, branches longer and finer, flowers are also more and more small. Winter pruning depends on the variety and cultivation purpose, when the pruning to leave branches, and pay attention to the overall shape of the rose plant, large Lady banks' rose varieties should be left 4-6 branches, 30-45 cm long to choose a side of strong bud, cut off the upper branches, vines or varieties to sparse to old technology, cut off weak branches, sick branches and cultivation of the main trunk.
It is easy for Lady Banks' rose (Rosa banksiae) to survive by cutting with hard branches before and after sprout or semi-hard branches before and after flowering.In the growth season selection of robust branches, at the lower end of the section carved, surrounded by plastic film into bags, filled with soil, after watering the bag mouth tied tight, keep the soil moist, have a very high survival rate.
The dormant period of Lady banks' rose (Rosa banksiae) can be naked root transplanting, transplanting should be strongly cut branches and tendrines. Keep the soil moist during the growing season to avoid standing water; After sprouting in spring, apply compound fertilizer once or twice to promote big flowers and taste sweet. After winter, apply decayed organic fertilizer in the trenches at the roots and pour permeable water. Prune the Lady banks' rose once in winter or early spring, removing long, dead, diseased branches and overdense branches to increase ventilation and light inside the plants.
Lady Banks' Rose (Rosa banksiae) propagation can be cuttings or layering. Cuttings before and after spring germination with hard branches or before and after flowering with semi-hard branches cuttings, are easy to survive the use of high-altitude lamination method.In the growth season selection of robust branches, at the lower end of the section carved, surrounded by plastic film into bags, filled with soil, after watering the bag mouth tied tight, keep the soil moist, have a very high survival rate.
In addition, sowing methods can be used to propagate. For some excellent varieties, use rose or single Lady Banks' rose as rootstock, grafting, bud grafting, split grafting can be done.
Lady Banks' rose (Rosa banksiae) disease has root rot, and the disease was severe in summer. When the infected Lady banks' rose was found, it was removed in time and 70% PCB 4kg was mixed next to the plant or soil was disinfected with formalin.
Disease has root rot, can use 70% pentachloronitrobenzene powder and plant ash (1:30) to withdraw next to the Lady banks' rose, prevent spread.Insect insects have aphids, can be used to kill 40% diethoate 800 times spray;Ground tigers and grubs can be killed by poison baits.
Another brown spot, white silk, such as appropriate. Early harm silver moths can use 80% of the enemy early 800-1000 times the spray.
Another black aphid, negative locusts such as short horn harm.
