The so-called management after grafting is to create the most suitable conditions in terms of temperature, humidity, and light, so that the grafted camellia can heal, sprout, and branch as soon as possible. Early grafting of old branches, because the temperature is relatively low, the formation of callus is relatively slow. The anvil and ear healing takes 5 to 6 weeks or even longer. If it is grafted from May to September in the warm and wet season, the anvil and ear healing time will be shorter, and generally it will heal in more than one month. Twig grafting may also be shorter.
The management of grafting in the old branches in early spring is the most difficult because the temperature is low and appropriate measures must be taken to keep them warm. For the grafted pots, put a thicker plastic film bag on the scion, place it indoors or in a greenhouse, let it be exposed to the sun, and if necessary, warm it indoors. Keep room temperature between 15°C and 20°C during the day and 10°C to 15°C during the night. After mid-April, temperatures rise and can be moved outside and shaded properly. In the warm and wet season, grafted in pots, after the grafting, set up ring sheds, cover the plastic film to moisturize, and then cover 90% of the plastic film on the shading net. During the day, the air temperature is too high, you can spray a few times on the plastic film in the ring, or open the two ends of the ring for 1 to 2 hours before and after noon to reduce the temperature inside the shed. One month later, the plastic film was uncovered at night to allow it to receive dew exposure and gradually adapt to the shed environment. After one and a half months, all plastic films were peeled off (if shade was needed at the time of summer, shading was also gradually shortened, and the shading time was gradually shortened), all leaf buds on the rootstocks were peeled off, and they were picked up afterwards and thin fertilizer was applied.
The success or failure of camellia grafting in addition to temperature, but also pay attention to light and humidity. Camellia, which is put on a plastic bag after grafting, should be placed in a place where there is no sunlight and it is bright. After half a month, gradually touch the sun under the shade, from time to time, the light from weak to strong, in order to facilitate the photosynthesis of the leaves, to provide anvil, ear healing and scion growth and development of nutrients. If the temperature is relatively low, the light reception can be slightly stronger; if the temperature is higher, the light reception is correspondingly weakened, and the time should be appropriately reduced.
After the anvil and ear are healed, the humidity in the plastic bag must be properly reduced because the rootstock has begun to provide moisture to the scion. The moisture required for the scion no longer depends on the moisture in the plastic bag; the leaves of the camellia are There are waxy, leaf transpiration and the ability to absorb water are relatively poor, if the humidity in the plastic bag is too large, it will cause the first of the scion on the scion mildew, black, and then the leaves fall off, leaves buds withered, then live scion will be re- death. When reducing the humidity in the plastic bag, it should be gradually reduced. Generally, you can take this approach: First, cut a few holes under the plastic bag, then cut a few more holes a few days later, and let the plastic bags open to the outside world gradually. Then remove the bag. This is safer. After the bag is unpacked, it is placed in the shade. When the soil is dry, a very thin nitrogen fertilizer is applied, which also promotes the vigorous growth of leaf buds on the scion. If the weather is dry, sprinkle water on the scion. After half a month, the pots were moved to the shade to receive light.
The success or failure of camellia grafting should also be noted that, when grafting, the rootstock section and scion space must be sealed with wax or tin foil and plastic to prevent bacterial infection.
The proportion of the extract is generally not very clear ingredients and content.
Such
as 10 kg of scutellaria extract extracted into 1 kg of powdered
