This article summarized the ecological cultivation techniques for blueberry whole industry chain from aspects such as site selection,soil improvement,variety selection,cultivation,and field management.Considering factors such as sunlight,soil and terrain conditions,priority is given to choosing sunny hillsides or open plains with sufficient sunlight.The soil pH should be between 4.0 and 5.0,and the terrain must be flat and have good drainage.Sulfur powder is applied to adjust the soil pH,and organic materials such as decomposed farmyard manure and peat soil are used to increase the organic matter content of the soil.In cold northern regions,dwarf or semi-highbush blueberry varieties can be chosen;in warm and humid southern regions,southern highbush or rabbiteye blueberry varieties can be planted.The best time for planting blueberries is from December to January of the following year.Pollen trees should be planted in a ratio of 3∶1 or 4∶1 according to the main cultivar and pollinator cultivar.Strengthen field management,apply organic fertilizers and microbial fertilizer,and perform reasonable pruning.Adopt agricultural control measures(preferably using disease-resistant varieties,timely removing diseased and dead plants,etc.),physical control(such as insect traps)and biological control(predatory insects,biological preparations,etc.)measures for green control of diseases and pests.Implement precise harvesting and cold chain transportation.This article provides a reference for the green ecological cultivation of blueberries and the sustainable development of the blueberry industry.
