黑龙江省位于祖国北部,气候寒冷,无霜期短,全省平均气温在零度以下长达五个月之久,一年中只有六个月左右适宜露地蔬菜栽培。随着人民生活水平的提高,蔬菜生产的季节性与居民消费的经常性矛盾更加突出,由于受自然条件的制约,冬春两大蔬菜淡季明显,因此发展蔬菜保护地生产,对调剂冬春蔬菜淡季供应,实现蔬菜周年生产,有着重要作用。
Heilongjiang Province is located in the northern part of the motherland. It has a cold climate and a short frost-free period. The average temperature in the province is below zero degrees for up to five months and only about six months in a year are suitable for field vegetable cultivation. As people’s living standards improve, seasonal conflicts between vegetable production and household consumption become more prominent. Due to the restriction of natural conditions, the two major vegetables in winter and spring are obviously off-season. Therefore, the development of vegetable production areas is of great importance. Off-season supply, annual production of vegetables, has an important role.
