为了探索杂交稻工厂化育秧的方法,以及相应的高产栽培技术,进一步提高水稻生产机械化程度,1979年我们采用无土、有土两种工厂育秧方式与露地育秧对比,取得了一些成果。 一、试验概况 1.试验设计 无土水培分粪水、高氮、低氮三种处理;有土育秧分熟土和河泥两种,均与常规露地 In order to explore hybrid rice plant seedling breeding methods, and the corresponding high-yielding cultivation techniques to further enhance the mechanization of rice production in 1979, we use soilless, earthy two plant nursery methods and open field seedling contrast, and achieved some results. First, the test profile 1. Experimental design soilless culture sub-manure water, high nitrogen, low nitrogen three kinds of treatment; soil nursery seedlings and mud two points, both with the conventional open field
