Grafting method of tree-shaped rose Cultivation of tree-shaped rose by secondary grafting method

Select vigorous, upright and 2 ~ 4 m dry height of Radix Aucklandiae for transplanting. Before transplanting, the soil was disinfected in the field, and soil pests were killed with diflubenzuron and carbofuran. When planting, the lower segment of Radix Aucklandiae is soaked with mixed drugs such as chlorothalonil, rooting agent and carbendazim with appropriate concentration for disinfection and rooting, the upper segment is sealed with paraffin, and the upper branch is coated with vaseline and hormone mixed drugs to promote lateral bud. After planting, dripping the tree with the mixed liquid of rooting element, auxin and lianmycin is beneficial to the rooting, germination and lateral branches of the trunk. After 1 ~ 2 years domestication and cultivation, it can be used as a rootstock when 3 ~ 5 branches grow at the top and the degree of lignification is high.

When grafting, choose thick rose branches without diseases and insect pests as scions. For the first time, rose buds were grafted on the branches of Aucklandia lappa, and 2 ~ 3 buds were grafted on each branch in different directions, with the spacing of 15cm. After the first grafting, strong buds will emerge from the grafting point and grow into many strong branches, which will be used as rootstock for secondary grafting in time when there is no lignification. In the second grafting, the upper part of the strong branch is cut from 1/4 ~ 1/3, and a knife is drawn longitudinally to the xylem outside the cut lower part to pry open the cortex; Then, the rose branches that meet the requirements, are robust and free from plant diseases and insect pests are selected as scions, the length is 15cm, the upper end has 1 ~ 2 buds, and both sides of the lower end are cut into horseshoe-shaped slopes respectively; Then insert the scion from the cortex pried open by the rootstock, so that the torn cortex at the upper end of the rootstock is slightly exposed, then tie the grafting place tightly with plastic strips, graft 2-3 scions from the same branch in different directions, and timely bagging and heat preservation. After 7 days, the cuttings began to germinate, and after one year, they could blossom, initially forming colorful tree-shaped roses.

Cultivation of Dendritic Rose by One-time Grafting Method

Select Aucklandia root with high lignification, stout, no pests and diseases, diameter of 3 cm ~ 5 cm, and stem height of 1m ~ 1.5m, and cut it from two internodes below the top of the trunk, leaving more lateral buds to promote its germination into lateral branches. Transplanting to the field, and making rootstock after survival. When grafting, young or medium plants with good color, strong dryness, vigorous growth, many branches and good crown shape should be selected as needed. I use branches as scions. Branches cut during pruning in winter can be stored in sand for later use: they can also be used for grafting. When the scion needs to be preserved, it can be quickly dipped in paraffin liquid to form an extremely thin wax film on its surface, then packaged in plastic bags and placed in a low temperature and humid place for later use.

The grafting time is different in different regions, and the grafting time is also different in the same region and different years affected by climate. The announcement time is from early March to mid-April, when the rhizome juice begins to flow.

Splitting method can be used for one grafting. Firstly, the center of the cross section of the rootstock is cut vertically with a cleaver, and the depth is about 3 cm ~ 4 cm. Both sides of the base of the scion are cut into 3 cm ~ 4 cm long wedges, and 2 ~ 3 buds are left on them. Pry open the rootstock with a knife and insert the scion, and align the rootstock with the cambium of the scion. If the thickness of scion and rootstock cortex is different, the scion skin should be slightly close to the center of rootstock. The grafting site should be tied tightly with plastic strips. Two or three scions are grafted on the same branch in different directions and positions, and the scions should be bagged and insulated in time to promote survival.

Bud grafting can also be used for one grafting. Choose full rose bud as scion, use aucklandia as rootstock, cut off the bud with a blade, leave a distance of more than 5ram from top to bottom, make a flat cut, and cut the lower end into 45. Oblique angle Select thicker branches on the rootstock, cut them into xylem, the section size is roughly the same as that of the scion, the lower inclination angle is the same as that of the scion, the cambered side should be close, the plastic wrap should be cut into long strips, wrapped tightly from bottom to top, and the second circle should cover the first circle to prevent air leakage; The bud is only wrapped in one layer, and several layers can be wrapped up and down. Wrap it tightly, cut off the extra roots and branches, wrap the incision and water it. Two or three buds are grafted on the same branch in different directions and positions. Wipe off the sprouts on the rootstock in time, and pick the film with a toothpick after the scion germinates to let the buds leak out.

Management of roses after grafting Strengthen the management of fertilizer and water, and check the survival of grafted seedlings in about 25 days. If the scion has sprouted or the scion is bright green, it will survive. Otherwise, replanting should be done as soon as possible. When the scion is bagged, when the ear bud length is more than 3cm, the bagged scion can be cut 1 small hole to refine the bud, and the bag can be removed in 5 ~ 7 days; When the ear lobe is longer than 10cm, use a sharp knife to cut off the binding tape on one side, and be careful not to touch the ear lobe.

After the ear buds develop into branches, they should be pruned as needed to promote the formation of an ideal tree. Timely and reasonably prune after flowering, and cut it below the third compound leaf of the flower; If there are new buds under it, they should be cut off at the top of the strong buds to promote the vigorous growth of new branches and sprout early. Strong branches are cut less and cut late; Cut more weak branches, first. When pruning, pay attention to keep the buds strong: only the terminal buds are left after the buds appear to concentrate nutrition and promote the flowers to be big and colorful.

In early summer and midsummer, it is necessary to shade properly, spray more water to cool and moisturize, and pay attention to maintaining air circulation.

Pay attention to scientific fertilization. Fertilization is mainly based on base fertilizer, which can be decomposed fertilizer mixed with bone meal or hoof pieces; Topdressing every 10 day/time during the growth period, cake fertilizer water and liquid fertilizer diluted with bone meal, calcium superphosphate or potassium dihydrogen phosphate can be added for topdressing.

Introduction to the purchase of Chinese rose 1. Wenxiang: Nowadays, families pay attention to multifunction when buying flowers. If they have more fragrance, they will have one more function. We should be patient to find it. It's all about smell when you buy it. The strong fragrance will stay, and the light fragrance without fragrance will be eliminated. And the flowers should be chosen around May 1 and June 1. At this time, the temperature is suitable, and the fragrance, color and rhyme of the flowers are good, which can fully display the level. There are not enough flowers in midsummer. Should be deleted. Only by removing summer flowers and preserving tree strength can autumn flowers bloom well.

2, look at the appearance:

(1) See the pattern selection? High-filled hemmed edges? It better be. Tall. Seen from the side, the pattern is towering. A full heart, a few petals in the heart should be wrapped inside, not exposed. As for the eversion flap, it is required to curl into a triangle.

(2) The petals should be slightly thicker and have a silky velvet texture.

(3) According to the plant type, high-growth varieties are suitable for family cut flowers and flower cultivation, and varieties with good clustering and slightly lower height should be selected.

(4) see if you are sick. Chinese rose is strong in ground planting, weak in potted plants, and there are many patients, so it needs to be treated regularly to prevent it.

(5) See whether the original pot and potted commercial flowers should have grass in the pot and moss outside the pot, indicating that the original pot is original. What if it's not? Fupen? Don't buy new flowers. If the commercial flowers are made of soft plastic pots, they should be torn off immediately after being bought back, and the original lump should be transferred to a soil pot for cultivation.
