How to manage blueberry cuttings after planting? Master these key points
Blueberry is a berry belonging to the Ericaceae family. In China, it not only has a wide wild population, but its cultivated area is also constantly increasing. However, due to prolonged cultivation, some long-time growers need to continuously propagate it to protect their planting benefits. The most commonly used propagation method is cutting propagation, so how should it be managed after cutting? Below, the editor brings you the key management points after blueberry cuttings. Let's take a look!
1. Water management
Blueberry prefers water, especially after cutting, sufficient water must be ensured to promote branch rooting, and we must keep the soil moist. However, attention should be paid to the amount of watering; it should be neither too much nor too much. The water temperature should also not be too low, to prevent affecting seedling growth. The more important watering time after cutting is from May to June each year, when the branches gradually grow leaves, but the roots have not yet fully grown out. If water is insufficient, the branches will find it difficult to root, and in severe cases, the branches may die. When the branch leaves gradually turn green, it means the branches have begun to root.
2. Reasonable fertilization
Unlike other crops, before cutting, it is not suitable to apply base fertilizer into the cutting substrate. And after cutting, before the branches have rooted, no fertilization is needed. If fertilized, it will have a certain impact on the rooting and growth of the branches. When the branches begin to root, fertilization can begin, promoting branch growth and enhancing growth capacity. When fertilizing, attention should be paid to the form of the fertilizer, with liquid fertilizer as the main type. Control the amount of fertilization well to prevent fertilizer damage. In the early stage of its growth, about once every 5-7 days, and after each fertilization, attention should be paid to removing fertilizer from the leaves to prevent leaf burn.
3. Transplanting and planting
After cutting, fertilizer and water management should be done well, and intertillage and weeding should be strengthened to create a good development environment for blueberry branches. After the branches take root from cutting, generally overwintering is carried out on the seedling bed, but in areas with lower temperatures, transplanting can be carried out from September to October each year. And those overwintering on the seedling bed must also do a good job in overwintering management, water with overwintering water, apply sufficient fertilizer, and then earth up on both sides of the plant. Increase the soil temperature and enhance the plant's cold resistance. In the second year, after the temperature gradually rises in spring, transplanting can begin. When transplanting, attention should be paid to transplanting with soil.
4. Pest and disease control
During the blueberry cutting seedling period, various pests and diseases are very likely to occur, so pest and disease control work is also one of our management points. We should regularly disinfect the seedling bed, but attention should be paid to the use of disinfectants to prevent harm to blueberries. Then frequently observe the seedling bed, and after discovering diseased plants, timely remove them to prevent the spread of the disease. Then according to the specific disease situation, spray the corresponding control agents into the seedling bed. Do a good job in ventilation and air exchange to prevent the greenhouse temperature from being too high and reduce fungal diseases.
The above is a brief introduction to the key management points after blueberry cuttings. The management work after cutting is very important. If management is poor, it may lead to death, and even if it survives, the plant's growth capacity will be weak, pests and diseases will occur severely, and the flowering and fruiting rate will also be affected.
