Recently, Cong Yijun, the Agricultural Technology Promotion Center of the People's Government of Gulouzi Township, Kuandian Manchu Autonomous County, Dandong City, Liaoning Province, called this newspaper to inquire about how blueberries are grown and managed in the Northeast. To this end, the reporter interviewed Wei Yongxiang, dean of the Dalian Branch of the Liaoning Academy of Agricultural Sciences. He answered the questions that need to be paid attention to in the blueberry planting in the solar greenhouse. There are many varieties of blueberries in the variety selection, but the selection of the varieties must be based on the local natural environment and market demand, and the most suitable varieties and cultivation methods should be selected according to local conditions. At the same time, we must also pay attention to the selection of varieties with better resistance to pests and diseases, because inferior varieties will not only affect the growth of trees, but also seriously damage the yield and quality of blueberries. It is advisable to use fresh blueberry varieties with early maturity, large size, high yield, good quality and low demand for cold. Soil-modified blueberry planting requires a relatively high soil. It is preferred for acidic soils. The pH value is generally 5.5, and the soil permeability is good. If the soil is not well ventilated on the clay floor, it is easy to cause poor root growth. If the soil is not improved in general, the quality of blueberries will not be improved. Temperature management Blueberries can only heat up after satisfying the required cooling capacity. Do not prematurely too fast when warming up, if too early too fast, easy to cause blueberry bloom, low fruit set rate and other abnormal phenomena. In general, the nighttime temperature is preferably above 8 °C, and the daytime temperature is controlled between 22 °C and 25 °C. Flower and fruit control should be done in time to assist in pollination, flower thinning and fertilization. During the flowering period of fruit trees, bees can be used for pollination to improve the pollination probability and fruit quality of blueberry trees. Pest Control Greenhouse Blueberry must be disinfected and sterilized at night during the warming of the greenhouse. Spray fungicides and insecticides before flowering to prevent the occurrence of pests and diseases, achieve green and safe production, and improve yield and quality. Plastic trimming of blueberry pruning can be divided into long-term pruning and eye-cut trimming. The main purpose of blueberry plastic pruning is to adjust the tree structure, adjust the relationship between vegetative growth and reproductive growth, and solve the ventilation and light transmission. Fertilization and fertilizer regulation should be carried out in the germination stage, flowering stage, fruit expansion period and fruit picking of blueberries. Fertilization must be reasonable, and less application should be carried out. Disclaimer: Some articles on this website are transferred from the Internet.
