北方寒地水稻两段式育苗高产栽培技术是利用当地晚熟高产品种,采用温室育苗、大棚育苗两个阶段保温育苗,培育大龄多蘖壮秧,大田稀插,延长水稻营养生长期,以实现水稻优质高产的增产技术。采用该技术平均亩产水稻700kg以上,比常规钵育水稻增产20%以上,并且其中分蘖穗产量占总产量 Northern cold paddy two-stage high-yielding cultivation techniques is the use of late-maturing high-yielding varieties of local varieties, the greenhouse nursery, nursery stocking incubator incubation in two stages, nurturing older tiller seedling, field sparse interpolation, prolonged rice vegetative growth in order to achieve rice High yield and high yield technology. Using this technology, the average mu yield of rice more than 700kg, paddy rice than conventional paddy yield more than 20%, and of which tillering spike production accounted for the total output
