Labins cherries are a medium-late maturing variety. The fruit shape is slightly flat and long, and the flesh is Q-shaped, slightly light red, and has a sweet and sour taste.
Lapins was bred by the Canadian Summerland Agricultural Research Institute in 1965 through a Pioneer × Steiner cross. It is a self-flowering, short-branched, late-maturing variety and is one of the key varieties promoted in Canada. Introduced to Yantai, Shandong Province in 1988. The fruit is large, with an average weight of 8 grams per fruit and is nearly round or oval in shape. The fruit stem is medium short and medium thick, and not easy to wilt. When mature, the peel is purple-red, shiny, beautiful, and thick and tough. The flesh is red, thick, crisp and hard, with a lot of juice, containing 16% soluble solids, and has good flavor and quality.
Labins is propagated by grafting. The rootstocks are ZY-1 and Chinese Cherry 90-1. The grafting methods mainly include spring woody budding and summer budding. The distance between rows of plants in the garden is 3m×5m or 3m×4m. The suitable tree shape is free spindle or modified spindle. Mainly pruning in summer, supplemented by pruning in winter. Pruning in summer mainly focuses on the opening angle and topping of new shoots. During the growing season, leggy branches and competing branches should be removed or thinned out in a timely manner, and longer branches should be removed multiple times to soften them.
Cultivation techniques of cherries
Before cultivating cherries, you should choose a plot with fertile soil, deep soil layer, good drainage and irrigation, suitable pH value, and a pH value of 6~ Between 7.5. Since the roots of cherries are distributed vertically, they are usually concentrated in a soil layer about 20 cm deep, which requires loose soil. In addition, cherries cannot be planted in heavy clay soil, and the plot must be close to roads to facilitate transportation.
The planting density of cherries mainly depends on soil, rootstock, variety and other conditions. If the terrain is flat and the land is fertile, choose the "Y" shape method for dense planting. According to the method of 1 meter × 3 meters, the density is 200 to 210 plants/acre. If you choose natural open-shaped or natural cluster-shaped shaping, follow the method of 2 meters × 3 meters or 3 meters × 4 meters. If the cherries are in their infancy, the density should be increased and thinned after the garden is established to control the planting density of the cherries.
