河大夏５１旱稻是河北大学生物系为北方节水农业培育成功的最新科研成果。该品种生育期９５～１００天，与中早熟玉米相似，一般凡是收获小麦以后播种玉米的地区都能种植，６６７ｍ２（亩）产３５０～４００ｋｇ（公斤），比过去推广种植的旱稻品种增产８０％以上。 该品种株高 Rivers and summer 51 Upland rice is the Department of Biology, Hebei University for the northern water-saving agriculture to cultivate the success of the latest scientific research. The variety has a growing period of 95-100 days, which is similar to that of middle-early maturing corn. Generally, all varieties can be planted in areas where corn is harvested after wheat harvesting. The yield of 667m2 (mu) is 350-400kg (kg), 80% more than that of the upland rice variety popularized in the past. the above. The variety of plant height
