How to graft Magnolia safflower? Grafting method and Post-grafting Management of Magnolia safflower

How does red flower magnolia graft propagation? What are the management points of safflower magnolia after grafting? The following is to bring you safflower magnolia grafting technology and methods.

1 Grafting time

In early spring when sap has not yet sprouted, choose no wind or breeze sunny days. Grafting in Baojing County is good from the beginning of February to the middle of February. Grafting survival rate is very low after late February.

2 Grafting methods

Single bud grafting.

3 Rootstock selection and treatment

3.1 rootstock selection

2 - 3 year old Magnolia denudata is selected as the rootstock, which has no diseases and insect pests, straight trunk, uncracked bark and ground diameter of 1.5 - 3.0cm.

3.2 rootstock treatment

(1) Cut the rootstock 6~8cm above the ground, and the incision should be smooth.

(2) Select the smooth side of rootstock and cut it obliquely upward with xylem at the edge of incision with grafting knife. The incision is as deep as xylem.

(3) Cut the xylem vertically downward with a grafting knife at the incision. The incision length is equivalent to that of the inclined plane according to the panicle length, generally about 2.0~2.5cm.

4. Selection and treatment of scions

4.1 Selection of scions

selecting a 5-year-old flowering grafted safflower magnolia tree as a mother tree, selecting 1 - 2-year-old branches which grow healthily, have no diseases and insect pests and are full of buds on the mother tree, wherein the branch is 0.5 - 1cm thick, and the upper part, the middle part and the lower part of the branches selected on the mother tree can be selected.

4.2 treatment of scion

Scion should be picked up at the same time. If it cannot be picked up on the same day, the scion should be kept moist, wrapped with wet towel and placed in a ventilated and cool place indoors.

5 Grafting methods

(1) Cut the scion at 45° at the position 2.0~2.5cm below the scion bud, and the incision shall be smooth; cut the scion bud at 0.5cm above the scion bud, and cut off the bud.

(2) Cut a long slope smoothly on the side of scion bud, the back of lower incision and 0.5cm below bud. The slope should be smooth. When cutting the inclined plane, the left hand mainly fixes the scion with the big mother finger, index finger and middle finger, and the right hand uses the grafting knife to cut the xylem quickly and smoothly on the side of the bud, 0.5cm below the bud, and the cut surface is required to be smooth and smooth, and there must be no convex and concave phenomenon.

(3) Cut a short inclined plane about 1.0 ~ 1.5cm long on the side of scion bud and the front of lower incision with grafting knife quickly and smoothly at the position 1.0 ~ 1.5cm away from bud.

(4) union of scion and rootstock. Quickly insert the cut scion into the cut rootstock, requiring that at least one side of the cambium of the scion's long slope is aligned with one side of the cambium of the rootstock cut.

(5) Bandaging. After scion is inserted into rootstock, wrap scion quickly with grafting film. So that the two rootstocks and ears should be tightly bound, there should be no loose phenomenon. When bandaging, at least one side of the scion's long slope should always be aligned with the cut side of the rootstock, and the bandage should be tight, only the bud is exposed, not the wound. The operation process of dressing (personal experience): When a person is facing the scion, first look at the alignment of one side of the scion long slope and the side of the rootstock incision. Here, the left side of the scion long slope and the left side of the rootstock are aligned as an example. The grafting film is a mechanism circular self-adhesive grafting film, about 1.5cm wide. Right to scion, first open one end of grafting film, not too long, hold this end with your right hand, hold the round part with your left hand, make the grafting film close to the stock and scion, bypass from the back, use force with both hands evenly, after your right hand wraps around the scion, exchange with your left hand, hold the round part of grafting film with your right hand, protect one end of grafting film, scion and stock with your left hand, prevent scion from moving, then quickly wrap the grafting film counterclockwise with your right hand for 2~3 times, make scion and stock close, Cover the other end of the graft with the left hand from the top of the scion to the opposite side of the scion, circle twice in the same direction, fix this end of the graft film, circle twice in the same direction, cover the transverse incision above the rootstock with the graft film, and finally fix the graft film.

8 Management after succession

8.1 bud picking

Sprouting once every 15 days. According to my observation, grafting on February 11, March 13, grafted magnolia buds began to sprout, March 30, bud change big, bright, April 10 magnolia germination.

8.2 weeding

Be very careful when weeding, lest the hoe knock off the bud. It is best to pull grass near rootstock by hand. The frequency of weeding depends on the growth of weeds.

8.3 film release

When scion growth begins to be limited, the grafting film should be removed in time. Generally, the grafting film can be removed at the end of June. After the grafting film is removed, pillars should be set up in time to prevent the scion from being broken by wind.

8.4 fertilization

When scion grows 15~20cm long, nitrogen, phosphorus and potassium compound fertilizer can be applied appropriately once a month, and fertilizer can be applied at the end of National Day.

8.5 bingchong prevention

After scion bud begins to germinate, want to pay attention to observation, prevent red spider harm scion bud. Found that there are red spiders to timely spray control, medicine can first use 75% dichlorvos, 40% omethoate, etc., according to the author's experience, a barrel of water (referring to the standard sprayer bucket) plus 3 caps (referring to the cap of the potion) potion, spray 1 time can be.

In short, in the grafting process to do "tight, flat, accurate, fast." "Tight" means that the binding of the scion and the rootstock should be tight in order to form a healing tissue;"flat" means that the scion surface and the rootstock interface should be smooth and have no convex and concave parts, so that the two can be closely combined;"quasi" means that the cambium between the scion and the rootstock should be aligned when inserting the scion, which is the key to the whole grafting process. The cambium is not aligned and will not survive;"Fast" means that the grafting knife should be sharp, the grafting action should be agile, and the drying time of scion shaving and rootstock interface should be shortened as much as possible.

Above is safflower magnolia grafting technology and method, each farmer friend can collect first, learn again.

Appreciation of Manglietia rubra pictures and their cultivation methods

Born at an altitude of 1700-2500 meters in the mountain broad-leaved forest or evergreen deciduous broad-leaved mixed forest. Today's small series simply introduces the planting method of Manglietia rufica... Before introducing the planting method of Manglietia insignis, we should first understand it. Manglietia insignis is an evergreen tree with a height of up to 30 meters. The branchlets are glabrous or rust-colored or yellow-brown pilose at the nodes when young. Leaves leathery, oblanceolate, oblong or oblong-elliptic, flowers fragrant, pedicel stout, ventral red or purple, flowering 5-6 months, fruit 8-9 months. Produced in southwest Hunan, Guangxi, southwest Sichuan, born at an altitude of 900-1 200 meters in the forest. Nepal, northeastern India, northern Myanmar are also distributed.... Manglietia safflower planting methods are sowing, cutting and grafting. Sowing: harvest when fruit is ripe, dry and thresh first, rub off red aril, wash and dry in the shade, store in wet sand at low temperature, sow in spring of the following year. After sowing, the seed germination period is long and irregular, and the seedlings pay attention to shade when the summer temperature is high. Winter seedlings have poor cold resistance and should be protected. Cuttings: spring flowers or plum season, cut young trees 1-year-old shoots for cuttings. The rooting rate and survival rate of cuttings treated with 0.3% IBA solution before cutting were increased. Grafting: use Magnolia or Magnolia as rootstock, cut before budding in spring, high survival rate... Manglietia insignia planting site selection 800 meters above sea level in the lower part of the hillside or valley, the soil layer is deeper, loose, moist, fertile soil. It is not suitable to plant on ridges, peaks, barren soil or strong winds. It can be mixed with camphor, sassafras, fire nan, maple, pine and so on to create a multi-species mixed forest, container seedlings planted in cloudy days after rain in May-June. After 3 years of afforestation, young stand tending, mature stand closed, thinning stage. Deep ploughing of Manglietia insignis is an important cultivation measure. It can promote the development of plant roots and enhance the disease resistance of plants......................................... Reasonable fertilization of Manglietia insignis can promote the growth and development of medicinal plants, enhance their resistance and recovery ability after being damaged by diseases and pests. For example: white atractylodes rhizome apply enough organic fertilizer, appropriate increase phosphorus, potassium fertilizer, can reduce mosaic disease. However, the manure or compost used must be decomposed, otherwise the residual germs in the manure and the eggs of underground pests such as grubs are not killed, which is easy to aggravate underground pests and some diseases....... After weeding, pruning and clearing of weeds and medicinal plants in the field, the residues damaged by diseases and insect pests and the fallen leaves in the field are often the hiding places of diseases and insect pests and the source of diseases and insect pests in the following year. Therefore, weeding, field cleaning and pruning combined with burning or deep burial of pest residues and litter can greatly reduce the extent of pest damage in the following year.... Although Manglietia rufus is widely distributed, it is scattered and has a small number. In addition, it is continuously cut and utilized, which is in danger of extinction. It is listed as a national third-class protected plant and a rare and endangered species. Today's introduction to the planting method of Manglietia rufus is here. Thank you for your appreciation.
