Xiaowen: On this issue, the reporter interviewed Wei Yongxiang, dean of the Dalian Branch of the Liaoning Academy of Agricultural Sciences.
Wei Yongxiang said that Shaanxi Wugong is not suitable for the cultivation of blueberries. Because blueberries have higher soil and climate requirements.
Soil blueberry planting requires higher soil, soil permeability is better, blueberry prefers acidic soil, and the general pH value is 5.5.
Fertilization of water, fertilizer, blueberry, germination, flowering, fruit expansion and fruit picking must be carried out. Fertilization must be reasonable. At the same time, the roots of blueberries are afraid of phlegm, excessive water accumulation or excessive time in hypoxic respiration, resulting in root death. Therefore, it is necessary to pay attention to drainage and control of moisture, and pouring less.
Temperature blueberries can only heat up after satisfying the variety of cold demand. 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.
Pest Control In the greenhouse, when blueberries are warmed up, they must be disinfected and sterilized at night, and sprayed with fungicides and insecticides before flowering to prevent the occurrence of pests and diseases, achieve green and safe production, and improve yield and quality.
