Pomegranate tree grafting method when grafting pomegranate tree, first select the variety of rootstock and scion. Grafting is the best choice for rootstocks, which are closely related to the tree species, so that the affinity is strong and the grafting survival rate is also high. Soft seed pomegranate can be selected as Rootstock to improve the survival rate and yield after grafting. When grafting pomegranate trees, it is suggested to use split grafting method.
It is suggested that the grafting time should be from March to April every spring. At this time, the climate is relatively warm and the survival rate of pomegranate trees after grafting is also high. However, the specific grafting time needs to be adjusted according to the local climate. Before grafting pomegranate trees, sterilized scissors can be used to make a vertical incision on the rootstock, and the length of the incision can be controlled at about 5cm.
When melting, first cut the paraffin into small blocks, put it into an iron can, and prepare plastic plant pots to fill with water. Then put the tin in water and heat it continuously to melt it. In addition, more robust branches should be cut from trees with good growth as scions, and then one end of the scion can be trimmed into a triangle. Pay attention to keep three tender buds on the scion during pruning.
In case of long-term rain and rising groundwater level, it is easy to cause root rot. at this time, the transmittance should be increased, and the two ends of the film can be uncovered to facilitate ventilation. At the same time, ditch cleaning and drainage should be paid close attention to. When the seedlings shoot for the second time in mid July, remove the plastic film cover in the morning and evening or cloudy days after the rain. As the flower buds and axillary buds of scion coexist at the same time, which affects the growth of seedlings, attention should be paid to removing the flower buds. One month after grafting is the key period for seedling survival.
However, in different seasons, the grafting methods are also different, and the root grafting method should be selected in winter. It should be noted that the fertilizer should be diluted with water before watering, so as to avoid the situation of root burning of big trees due to the high concentration of fertilizer. If there has been no survival performance, it means that the grafting has failed. The time of grafting should be selected to improve the survival rate, which can be carried out in May.
After the grafting of big trees, it is necessary to control the watering amount to avoid excessive water, which will lead to the decay of the skin of the big trees. In addition, when watering the big trees, the water cannot be splashed on the fresh-keeping film to avoid the penetration of water, which will lead to the blackening of the incision. After the bark connection of the tree is completed, it is necessary to apply compound fertilizer rich in nitrogen, phosphorus and potassium to supplement nutrition, so as to provide sufficient nutrients for the tree, so as to speed up the growth rate of the tree.
Therefore, its appearance has nothing to do with plums. It is completely two different fruits. In fact, these three kinds of fruits are very delicious fruits, rich in nutrition and very sweet taste. There are differences in appearance and taste, and each has its own advantages. However, due to the low efficiency of strip propagation, it is difficult to produce a large number of seedlings at one time, and the requirements of various strip management are inconsistent, so the cost is high and it is not suitable for large-scale operation.
The specific grafting time of different fruit trees is different, but most fruit trees should be grafted in spring, and the best grafting time should be between waking insects and the spring equinox. When to graft fruit trees? Fruit tree grafting is usually carried out in spring. The best grafting time period should be between the annual sting and the spring equinox. At this time, the buds of fruit trees have not germinated, and the survival rate of grafting is better at this time.
Litchi can be wrapped 15 ~ 20 days after peeling. The method of sludge discharge is to use the topsoil of paddy field, add a small amount of yellow mud, an appropriate amount of water and straw, and mix them into straw pulp. It should be noted that the grafting time of fruit trees should not be too early, otherwise the life activity of fruit trees will be affected due to low temperature. At the same time, the grafting time of fruit trees should not be too late, because after bud germination, it will consume a lot of water and affect the survival rate of fruit trees.
In addition, the matrix filled at the beginning should not be too wet, so as not to cause new wound decay and not easy to form a cambium. However, in case of dry matrix, it can be supplemented by water injection with syringe. By using the rooting ability of the branches, the branch of the mother plant is buried in the soil, given the environmental conditions for rooting, and then cut off the mother plant for planting after the lower part takes root, so as to become an independent new plant.
Generally, roots can be developed within half a month after banding, and the roots of surviving seedlings can be seen outside the film. Generally, the trees are transplanted with soil mass in late September, and sufficient root fixing water is poured. In management, attention is paid to dry irrigation and waterlogging drainage, and thin organic fertilizer is applied appropriately. They can be planted in late October. The layering propagation and seedling raising technology of Magnolia grandiflora is a part of the cultivation technology of Magnolia grandiflora.
Starting from the biological characteristics of different tree species, it is necessary to adopt appropriate methods to press the strip at an appropriate time, and keep it moist, ventilated and at an appropriate temperature during the growth period, so that it can take root well. The period of separation and layering must be based on the growth of roots, and there must be a good root group before it can be divided. Larger branches cannot be cut at one time, but should be cut in 2 ~ 3 times.
Special attention should be paid to the protection of newly isolated plants, such as irrigation and shading. Seedlings afraid of cold should be moved to the greenhouse for winter. The advantage of layering propagation is that layering method is simpler and easier than cutting method, and can maintain the excellent properties of some cultivated plants. However, this method can often obtain a few large seedlings at one time, so it is an economic and reliable breeding method for small-scale needs or amateur cultivation.
The whole process must be operated quickly. After cutting the rootstock and scion, they should be matched immediately, and firmly clamped with the grafting clamp, and then the grafted seedlings should be planted in the nutrition bowl. The third is the splitting method. First split the stem above the rootstock, then cut the upper part of the scion into a wedge and insert it into the cut of the rootstock. At this time, in case of high temperature and drought, which is easy to cause seedling burns, the coverage should be increased to reduce the light transmittance.
Adopting this grafting method, the rootstock seedlings used should be older. The rootstock seedlings should be sown first, and then the sprouting scion should be sown when they can be transplanted, which can be planted in the same nutrient bowl. The wedge surface requirements of grafted rootstock and scion mainly include triple cutting methods, namely single-sided wedge, double-sided wedge and tongue wedge. Single-sided wedge is suitable for oblique cutting and budding. The advantage of strip propagation method is that it is easy to survive and can maintain the excellent persistence of the original variety.
The double-sided wedge is more suitable for the split connection and top insertion method. The young stem is cut into double wedge surfaces from top to bottom, and the tongue wedge is mainly used for the close connection method. It needs to be obliquely cut into the stem from a certain position of the seedling stem with a blade. High branch pressing is most suitable from September to October every year. It is necessary to prepare a plastic bag filled with wet soil and put it directly on the circumscribed branches of Osmanthus fragrans. After binding, support it with a support to prevent it from breaking.
