The Developing Blueberry Industry in China

Abstract

The present situation of blueberry industry in China was summarized. The six main blueberry cultivation areas in China were reviewed and practical suggestions were made. Reference and guidance for water management of rabbiteye blueberry in Yangtze river basin was provided, and water physiological characteristics and water requirement of blueberry were also clarified so as to provide scientific management of blueberry. Effects of vinegar residue on soil physical and chemical properties, enzymatic activities, growth of blueberry, nutrient uptake, and fruit quality were studied. The effect of vinegar residue on the growth of blueberry and the mechanism revealed from the perspective of soil amelioration were also discussed from the results.

Parameterization and Calibration of Wild Blueberry Machine Learning Models to Predict Fruit-Set in the Northeast China Bog Blueberry Agroecosystem

“…Third, the Taylor expansion method is used to approximate the loss function thereby speeding up the process of optimization [52]. The predicted values of the tree ensemble model are computed using the formulae in Equations ( 4) and (5).…”

“…Bog blueberries are widely distributed and managed in the highlands of Northern China [4] as a major agroecosystem supporting the local rural economy. As of 2019, farmers in three provinces in Northeast China manage 3.5 million hectares (15% of the nationwide blueberry coverage) of bog blueberry with an estimated annual yield of 0.6 million metric tons (less than 5% of the national blueberry yield), according to the Heilongjiang Bureau of Agriculture and Forestry [5]. Increasing yield, fruit quality, and long-term economic stability in bog blueberry production requires better understanding of the fundamental ecological processes of cross-pollination as a result of various interacting factors.…”

Interactive climate-soil forces shape the spatial distribution of foliar N:P stoichiometry in Vaccinium uliginosum planted in agroforests of Northeast China

“…Vaccinium uliginosum L. (bog bilberry) is a perennial deciduous shrub inhabiting peatlands and moorlands in temperate and boreal tundras (Jiang et al, 2019). Its populations can also be distributed in the understory layer of temperate forests dominated by birch (Betula nana) (Ejankowski, 2010) and black spruce (Picea mariana) (Rohrs-Richey and Mulder, 2007;Duan et al, 2022).…”

Removal of Dominant Species Impairs Nitrogen Utilization in Co-Existing Ledum palustre and Vaccinium uliginosum Communities Subjected to Five-Year Continuous Interruptions

“…Abundant anthocyanin content and the diverse composition of its berries are the major factors of value for merchants of northeastern forest resources [13]. Natural habitats of V. uliginosum support an annual yield of 0.6 million metric tons of berries using an area of 3.5 million hectares in forests of northeast China, accounting for ~15% of nationwide berry cultivation areas up to 2019 [14]. In understory bogs of boreal forests subjected to cold temperate climates, V. uliginosum usually co-exists with Ledum palustre L. in communities that dominate the understory communities [15,16].…”
