黑龙江省水稻旱育稀植栽培技术,近几年已大面积推广应用,发展很快。但育苗床土调制,一般用浓硫酸、白矾、硫酸亚铁等作调酸剂,农民不易掌握、使用也不方便,且秧苗素质差,时有立枯病发生。因此,研制效果好,便于使用的调制剂,已成为我省发展水稻生产的当务之急。 Rice cultivation in Heilongjiang Province, dry cultivation techniques, in recent years has been widely applied, the rapid development. However, nursery bed soil modulation, generally with concentrated sulfuric acid, alum, ferrous sulfate for acid, farmers are not easy to grasp, is not convenient to use, and poor quality of seedlings, sometimes withered blight occurred. Therefore, the development of effective, easy to use modulators, has become the province’s development of rice production imperative.
