Tassel is a deciduous shrub or small tree, flowering from April to June and fruiting from September to October, and July is the best time for tassel grafting planning. There are three methods of tassel grafting. They are splicing, ventral grafting, split grafting, skin grafting and leaning grafting. Today, the editor is going to talk about the advantages and disadvantages of using tassel as rootstock to graft sweet-scented osmanthus. I hope it can be helpful to everyone.

I. the advantages of using tassel as rootstock to graft sweet-scented osmanthus.

1. Good affinity with sweet-scented osmanthus and high survival rate

A, sweet-scented osmanthus grafting selects apple, pear, peach, apricot and other species of the same family, the survival rate is relatively low, especially in the later stage, it is easy to appear poor compatibility, small feet and dead plants and so on.

B, and tassel as rootstock grafting sweet-scented osmanthus is different, no matter which kind of grafting method is used, the survival rate is relatively high, and the growth is good in the later stage.

2. It can shorten the adult age and blossom earlier.

A, in addition to the four seasons cassia population, you can also use other rootstocks of grafted seedlings, such as cutting seedlings, striping seedlings and lobular privet.

B. it takes 8-9 years for most seedlings from planting to flowering, and the time from planting to flowering can be shortened to some extent by using tassel grafted plants.

3. No roots and convenient management

General grafted sweet-scented osmanthus potted plants often have a lot of rootstocks, which need to be pruned frequently, which is troublesome to manage, but there is no such problem in using tassel, and it can also reduce some management work in cultivation, simple operation and save time.

4. Beautiful plant type.

Most of the tree crowns grafted with tassel are round and compact, and the ornamental effect is very good, which is more suitable for potted planting, while the grafted seedlings and self-rooted seedlings of other brick trees are evacuated, the crown is long or irregular, the whole looks scattered and empty, and the ornamental effect is poor.

2. Disadvantages of grafting sweet-scented osmanthus with tassel as rootstock

The only point of grafting sweet-scented osmanthus with tassel rootstock is dioecious, which will bring some inconvenience to seed retention and seed collection.

Artemisia annua, also known as Artemisia annua, Ar

1. Cultivation of female parent of chrysanthemum

1. Female parent culture: bonsai chrysanthemums (including Chrysanthemum morifolium, Chrysanthemum morifolium), which grow healthily and free from diseases and insect pests, are selected as female parents in December of the first year and January of the second year. The persistent roots are planted in the arranged nursery. The number of female parents depends on the production demand in the coming year, and rotten organic fertilizer or inorganic compound fertilizer is applied in the nursery.

2. Marking: make variety label and mark the female parent varieties.

3. Fertilizer and water management: after the female parent the Beginning of Spring germinated in the second year, do a good job in water and fertilizer management to promote its growth. For the female parents of Chrysanthemum morifolium, Chrysanthemum morifolium and Chrysanthemum morifolium, 20ppm 920 auxin should be sprayed in the evening when there is no rain every week to promote growth.

2. Rootstock culture

1. Sowing: after the seeds are mature in mid-October of the first year, they can be collected and sown. Of course, they can also be dug up in the field from November to December of the second year. Which one to choose can be decided according to their own actual situation.

2. Transplanting: the seedlings of Cyclobalanopsis lanceolata which were sown or dug in the field were transferred into a round tile pot with a diameter of 10-12cm from November to December to strengthen the management of fertilizer and water. When cold and cold weather, it is necessary to move the potted plants into the greenhouse or build a plastic arch shed to prevent freezing.

3. Rootstock classification: from March to April of the second year, it was classified according to the individual difference of Qingpeng, which was used for grafting high grafting chrysanthemum, big chrysanthemum, cliff chrysanthemum and art chrysanthemum respectively. The rootstocks used for grafting high-grafted chrysanthemum select individuals with plant height, no mulberry or millet in root, and strong apical growth dominance. The rootstock used for grafting Chrysanthemum morifolium was used to select the green pole individual with moderate plant height and more tillers in the root part. The rootstock used for grafting cliff chrysanthemum is a green pole individual with plant height, no millet or less millet in the root and strong tip growth. The rootstock used for grafting art chrysanthemum is a sturdy, branched green pole individual. The classification of rootstocks can shape the trunk and lateral branches of rootstocks according to the modeling design of bonsai chrysanthemums.

III. Grafting

1. Selection of female parent: among them, stratified high-grafted chrysanthemum should choose large flower varieties > 10cm or medium-sized flower varieties with flower diameter 6~10cm, while non-stratified high-grafted chrysanthemum should choose small flower varieties with flower diameter < 6cm. The mother of Dali chrysanthemum should choose varieties with long branches, soft branches and pure colors, such as Tian Jia, Mohe and so on. Cliff chrysanthemum, art chrysanthemum mother should choose short branches, flowers small and luxuriant varieties, such as the sky star.

2. Grafting: the grafting time is based on the time when the number of scions meets the grafting needs of bonsai chrysanthemums, in which high-grafted chrysanthemum and cliff chrysanthemum can start at the end of March as early as possible, while big chrysanthemum begins to grow to about 60cm. Art chrysanthemum can be early or late, but not later than early August at the latest. The scion should choose the semi-lignified chrysanthemum twigs with strong growth and free of diseases and insect pests. Generally, the twigs should spread out with 3-4 leaves. The split grafting method was used to cut the top of the branch of the rootstock, split the lcm from the center of the branch to the bottom, and cut each side of the chrysanthemum scion symmetrically and obliquely, in which the high-grafted chrysanthemum cut the top of the side branch of the main branch of the green pole with 3-5cm, then inserted the scion into the rootstock, wrapped the scion with plastic film, observed the survival, and repaired the dead.

IV. Cultivation

After grafting, it was cultivated according to the normal cultivation method of bonsai chrysanthemum until the chrysanthemum withered. Among them, the cultivation height of high grafting chrysanthemum can reach 500-700cm, the cultivation height of cliff chrysanthemum can reach 200cm-400cm, and the cultivation height of cliff chrysanthemum can reach 200cm-300cm, which can be used for celebration or exhibition to create festive, warm, tall, spectacular scene and atmosphere.
