Cultivation of Chinese rose

There are many cultivation methods of rose, among which cutting and grafting are the most common. The main method of grafting is bud grafting. The method of cutting propagation is introduced below.

1. Cutting period. Rose seedlings are mostly raised in spring and autumn, spring begins from late April to the end of May, and autumn begins from late August to the end of October. Cutting seedlings in autumn can not be divided into pots in the same year, young roots are underdeveloped, cold resistance is poor, so it is necessary to do a good job of anti-freezing in winter.

2. Prepare the basin soil. Small and medium-sized tile pots should be selected for cultivation, with a □ diameter of 15cm to 20cm. The soil used for cutting should choose loam with good drainage performance, mix with 30% ridge bran ash and set aside after mixing.

3. Selection of cuttings. Select the disease-free new branches on the strong growing rose mother plant and cut them into 7-15 cm long. The cuttings cut during the growing season had better have some leaves. In order to improve the survival rate, it is necessary to collect and water cuttings at the same time.

4. Cutting into the pot. Cover the drainage hole at the bottom of the selected basin with several tiles, add a small amount of sand and add the sifted coarse-grained soil, accounting for 1 × 5 of the basin height, which is beneficial to the later drainage, and then add the mixed soil, accounting for 3% of the basin height. After several shakes, the basin soil is more compact, and the basin □ leaves 1 to 5 without filling, which is used for watering. When the temperature is high in spring and autumn, the cuttings, such as soil, should not be too deep, and the cuttings should be buried with the full length of the cuttings. A 15 cm □ diameter earthen pot can cut 10-12 cuttings. After inserting, shake the basin a few times so that the soil particles are in close contact with the soil-like part of each cuttings. After each basin is inserted, it should be watered for a second time, and can be watered with a thin eye until water is left in the bottom hole.

Cultivation techniques of Chinese rose 1. Soil requirements for rose cultivation

A. Rose likes weakly acidic soil, and PH should be kept at about 6.5. if the soil is planted, it is best to use imported peat to improve the soil, so as to neutralize the acidity and salinity of the soil.

B. composition and proportion of rose cultivation substrate, coarse granular matter (coconut shell, coconut fiber), fine peat and organic fertilizer, and a small part of garden soil. Coarse particles account for about 1 beat 3 to 1 jump 5, and garden soil accounts for about 1 jump 10 or less. The main function of coarse particles is to permeate water and air, while the role of fine particles is to retain water and supply fertilizer. The function of garden soil is to improve the buffering capacity of the matrix together with organic fertilizer.

2. Disk selection in rose cultivation.

The size of a flowerpot. The minimum should not be less than 20 centimeters. The eyes of the pelvic floor should not be too small. It's not good to seep water that way. It's as big as a coin. The basin in our garden. They all have three eyes. Plastic pots or earthen pots are fine. It is best not to use porcelain pots. The permeability is not good.

3. Chinese rose is cultivated and watered thoroughly.

Dry water and wet drain. If you water it, you will water it thoroughly. When planted on the ground, he threw the skin tube into the pool. Fill the pool with water. This refers to when the temperature is higher in summer. It is appropriate for potted plants to seep down quickly after being watered. Stick a chopstick in the dirt. You can tell when the bottom is dry and wet. It can be watered 1-2 times a day when the temperature is above 30 degrees.

4. Fertilization control of rose cultivation.

Rose can not be fertilized at the beginning of budding, urea or compound fertilizer is applied when spreading leaves, potassium dihydrogen phosphate is applied when budding, and the interval between fertilizers is 10-15 days depending on the temperature. The higher the temperature, the shorter the interval. In this cycle, it is best to apply fertilizer before it rains. Occasionally, you can also pour some rooting water.

5. Cultivation and transplanting of Chinese rose

Because the rose moved its roots in the process of transplanting. Yellowing of rose leaves is a normal phenomenon. You can pinch off the yellow leaves. It's okay to lose all the leaves. Pinch boldly. After transplanting. Water should be watered less first. It is dry and watering. After a period of time, the rose will grow new roots and leaves. Don't worry.

6. medication control of rose cultivation.

The medicine should be given every half a month. Play every 10 days or so when the weather is hot. Sterilization and disinfection: potassium permanganate, chlorothalonil, methyl topiramate. The carbendazim played for a change. The higher the temperature, the shorter the interval. Insecticidal: dimethoate. DDVP, etc. Treatment of aphids: imidacloprid. Pesticides are poisonous. Pay attention to protection.

7. The cultivation of Chinese rose is beneficial to ventilation.

Whether it is courtyard cultivation or balcony cultivation, we must pay attention to ventilation. With good ventilation, rose flowers can grow healthily and reduce the occurrence of diseases and insect pests.

Cutting cultivation techniques of Chinese rose 1. Cutting time

It can be carried out in both spring and autumn. Spring is from late April to the end of May, when the climate is mild, the branches are strong, they can take root one month after planting, and the survival rate is high. Autumn cutting is carried out from late August to the end of October, when the cutting is affected by the large temperature difference between day and night, the rooting is relatively slow, it takes about 40 to 50 days to take root, and the survival rate is slightly lower than that of spring cutting.

2. Nursery site preparation

In the Xiangyang area, the plots with deep soil layer, loose structure, good permeability, rich humus and good drainage are selected as the inserting bed. Per mu of bed mixed with 200 kg of rotten farm manure (pig manure, cow manure), 25 kg of calcium superphosphate as base fertilizer, and then mixed with 20 to 30 kg of fire soil ash or grain bran ash to facilitate ventilation. In order to reduce the incidence of cutting seedlings, the soil should be disinfected before cutting: spray the soil with 50% special wettable powder 500-800 times, then cover it with plastic film for 3 to 4 days, and cut 1 week after opening the film.

3. Selection and treatment of cuttings.

From the middle and young mother trees of excellent varieties, 1-2-year-old spring shoots or current year-old autumn shoots with sturdy, full, strong growth potential and no diseases and insect pests were selected as cuttings. This kind of branch has high growth substance content and strong metabolic activity, so it is not only easy to survive, but also has good seedling quality and high price. Those who transport branches from other places for cuttings should pay attention to moisturizing and shading in order to maintain the vitality of the branches. The cuttings are about 8 to 12 centimeters long. Cut off the lower leaves, leaving only the upper 3 to 5 leaves. The survival rate of cuttings can be improved by pressing 50 cuttings into a bundle and soaking the lower part of the cuttings in 100ppmGGR6 solution for 1 to 2 hours.

4. Cuttage

Do as much as possible with pruning, with treatment, with cutting. Do not hurt the skin when cutting, generally use a small stick or finger to insert a small hole in the bed, and then put the cuttings into the hole. The cutting depth is from 1 to 2 to 3 of the cuttage length, and the row spacing is 10x15 cm. After insertion, the cuttings are compacted with hands and watered once, so that the cuttings are closely combined with the soil.

5. Plug-in management

A, set up arch shed and cover sunshade net. The plastic shed can adjust the temperature and humidity of the soil and air, and the sunshade net can prevent direct sunlight and reduce the temperature. The light transmittance of the sunshade net should be 20% to 30%. In addition to covering the sunshade net on the top of the seedbed, it is also necessary to hang curtains on the east and west side of the seedbed to reduce sunlight in the morning and evening. The best rooting temperature of rose is from 20 ℃ to 25 ℃. The temperature is too high. Besides covering the sunshade net, it can also be watered and ventilated.

B, watering: in the early stage of cutting, the cuttings have not yet germinated leaves, and the water supply should not be too much, usually once every 7 to 10 days. After a month, the panicle begins to root and shoot, and the water consumption increases gradually, which should be irrigated every 3 to 5 days. The amount of water should be determined according to soil moisture and air humidity, so that the soil is moderately dry and wet. The best moisture condition after cutting is that the field capacity of the seedling bed is about 80%, and the air relative humidity is 80% to 90%. If the humidity is too high, the amount of watering can be controlled and ventilation can be strengthened; if the humidity is too low, the amount of watering and spraying times can be increased.

C, fertilization: the amount of fertilizer needed for cutting is not large, and the basic fertilizer has been applied during soil preparation, so there is no need for soil fertilization before seedling transplanting, but foliar fertilization should be carried out. That is, after cutting for one month, 0.3% urea liquid fertilizer and 0.2% potassium dihydrogen phosphate liquid fertilizer are used in turn every half a month for foliar fertilization to promote rooting.

D, weeding: to pull out the weeds in the bed in time, do not move the seedlings.

E, seedling refinement: half a year after the seedlings take root, the ventilation and light time should be properly prolonged to improve the seedlings' ability to adapt to the external environment.

[methods of cultivation and culture of Chinese rose]

Looking at the beautiful and moving rose, in fact, it is not so easy to cultivate and breed. The cultivation of rose requires our dedication and care to cultivate the best rose.

1. Rose likes an environment with plenty of sunshine, good ventilation and shelter from the wind, so remember not to breed it in a shady environment; the soil will be loose, fertile and well drained neutral soil.

2. Reasonable pruning is the key to the air during the flowering period of the rose. At present, there are two main sprouting positions of the rose: 1 to 5 leaves under the flower; 6 to 9 leaves under the flower; potted rose and cut rose to calculate the date of flowering. About 45 days before flowering, comprehensive branch pruning, understanding the germination characteristics of Chinese rose can better help you cultivate Chinese rose.

3. Fertilization skills, good fertilization skills can make your rose grow faster, better and more advantageous.

☆ when the new generation buds do not germinate after pruning, spraying fertilizer with 0.2% urea on the leaves every 5 or 6 days can promote the germination of new buds

☆ if the plant grows fast and the new branch grows rapidly, when it is beyond the planned range, the growth can be delayed by controlling water supply. In the process of water control, after the branches and leaves wilted, spraying water in time, it was critical to recover within 1 hour.

The budding of new shoots of ☆ was later than planned, and the buds grew rapidly when 0.2% potassium dihydrogen phosphate was sprayed on the leaves every 5 or 6 days. Rose flowering period to consume a lot of water and body nutrition, water supply should be adequate.

4. The propagation methods of rose mainly include cutting and grafting propagation: the best time for cutting is half-stem cutting in late May after the first flower blooming, or hardwood cutting in late October, and grafting buds can be carried out from June to August. Cutting can be carried out at the beginning of germination, and the germination time of different climates is also different, so we should pay attention to seize the opportunity. Young shoot grafting is carried out in the growing season, when the rootstock sends out new shoots, the new shoots are cut off 3-6 cm away from the old ones for split grafting, and the scion is also used for tender shoots, whose thickness should be the same as that of the rootstock.

5. The prevention and treatment of diseases must not be ignored in the process of rose culture. Here are several common rose diseases and control measures.

◆ black spot: mainly invades leaves, petioles and tender shoots. At the beginning of the disease, purple-brown to brown spots appear on the front, and after enlargement, most of them are round or amorphous dark-brown spots. Can be sprayed with carbendazim, methyl thiophanate, daconine and other drugs.

◆ powdery mildew: White powdery substance appeared on both sides of the tender leaves, and the early symptoms were not obvious. after the appearance of 3Murray in the powdery layer for 5 days, the leaves showed water stains, gradually lost green and turned yellow, and caused the leaves to fall off when they were seriously injured. During the onset period, carbendazim and triadimefon can be sprayed, but the effect of Guoguang Inna is the best.

◆ leaf blight: most of the leaves were invaded by the tip or margin of the leaves, which were yellow dots at first, and then rapidly expanded into irregular spots. The seriously damaged whole leaves withered up to 2 bumps, and the diseased parts were chlorotic and yellowing, brown dry and shedding. In addition to strengthening the management of fertilizer and water, the diseased branches and leaves should be cut off in winter, the underground fallen leaves should be removed, the sources of initial invasion should be reduced, comprehensive control should be taken when the disease occurs, and fungicides such as carbendazim and methyl thiophanate should be sprayed.

◆ disease is mainly prevented. Germicidal agents are sprayed regularly in high temperature, high humidity or overcast and rainy seasons, and stone-sulfur mixture is sprayed in the dormant stage of seedlings to carry out comprehensive sterilization to ensure the healthy growth of seedlings and the strong growth of seedlings, which can resist the invasion of certain diseases.

[efficacy and function of Chinese rose]

1. The medicinal value of Chinese rose.

★ rose is a common gynecological medicine. In traditional Chinese medicine, it has the effects of promoting blood circulation, regulating menstruation, reducing swelling and detoxification, so it is often used to treat irregular menstruation, dysmenorrhea and other diseases.
