河北省黑龙港地区素有华北干槽之称,是华北平原历史上受旱、涝、碱害最重的地区,长期贫困缺粮。自农村实行生产责任制以来,形势大好,化肥用量比建国初期增长10倍以上,水浇地占50%。由于工农业生产的发展,缺水矛盾日益突出,常年缺水三分之一,枯水年缺水三分之二以上,水位年年下降。因此,要使黑龙港地区农业生产水平不断提高,必须走旱地农业与省水型抗旱农业相结合的路子。 Heilongjiang Province, known as the northern part of the dry trough in northern China, is the history of the North China Plain drought, waterlogging, the most serious base area, the long-term poverty and food shortages. Since the implementation of the responsibility system for production in rural areas, the situation is magnificent. The amount of chemical fertilizers has increased by more than 10 times than that in the early days of the founding of the People’s Republic of China and irrigated by 50%. Due to the development of industrial and agricultural production, the contradiction between water shortage and water has become increasingly prominent. One-third of the population is short of water year after year, and more than two-thirds of the water shortage season in the dry years leads to a drop in the water level every year. Therefore, in order to continuously raise the level of agricultural production in Heilongjiang, we must take a combination of dry land agriculture and water-saving drought-resistant agriculture.
