Cranberries are mainly produced in China's Heilongjiang Province, Canada's Columbia State and the United States of America's Wisconsin and so on, of which the city of Fuyuan, Heilongjiang Province, is Asia's largest cranberry planting area, and the United States of America's Wisconsin region of the cranberry production accounted for 46% of the world.
Many varieties of cranberries are cold-resistant, preferring moist, strongly acidic soil, and their planting is often chosen to build a garden in wetland conditions. Cranberry orchards should have adequate water sources for frost control, replenishing excess soil moisture evaporation, and for cranberry fruit harvesting.
Irrigation water should have a pH of less than 6, and soil pH should ideally be 4.0 to 5.5. Water sources include lakes, rivers, and reservoirs, and the reservoirs constructed should store enough water to supply cranberries.
Because cranberries are evergreen and semi-evergreen plants, the two main factors to consider when growing cranberries in cold northern regions are cold resistance and frost damage. Dry areas with little snow and high winds in winter are not suitable for cranberry development; areas with frequent late frosts, such as valleys surrounded on all sides are susceptible to frost damage during the flowering period when planting cranberries, which should be avoided as much as possible.
Cranberry planting technology
1, choose the right varieties: cranberries must choose the right varieties of cultivation, North America's main drawbacks are cultivated cultivars cultivated in 1996 Stevens. Stevens is a medium-ripening variety with large fruit, good coloring and good yield stability.
Benriere is another widely planted variety that is early maturing and has larger fruits, but is more sensitive to planting management practices and can be planted with several varieties in a single park to minimize risk.
2, soil conditions: cranberry rooting is not deep, the surface of the soil should be covered with 4 to 5 centimeters deep sand. The soil requirements are very high, peat soil is suitable for its growth disturbed Bu smack, in this soil, the probability of survival is increased at the same time, you can increase the fruiting period, and ultimately achieve the purpose of increasing production.
3, planting: North America's commonly used cultivation of slow hand technique is to cut off part of the cranberry vine when cultivating cranberry cons positive cranberries, sprinkled into the sandy soil, pressed into the soil, and finally watered and fertilized, generally a few weeks after the new roots to become a new plant, and the longer the better.
4, pollination: cranberry belongs to self-pollination, but the yield is very low, and the fruit is particularly small, so it is a variety of mixed cultivation, mixed pollination, and sometimes artificial pollination to ensure that the yield.
