整地是搞好育苗的基础。整地以后做什么样的床?是高床、平床还是低床?这要看育苗地的地势和气候条件。一般高床适合在地势低、降水量大的地方;低床则相反;平床则介于二者之间。为了选择一种适合多种地势和气候条件的育苗床,经过多年的生产实践,总结出一种对沟床。我们认为这种对沟床优点很多,值得推广。 Soil preparation is the basis for nurturing seedlings. After the preparation of what kind of bed? Is a high bed, flat bed or bed? This depends on the topography and climatic conditions. General high bed suitable for low-lying, large precipitation areas; low bed is the opposite; flat bed is in between the two. In order to choose a variety of topography and climatic conditions nursery bed, after many years of production practice, summed up a pair of ditch bed. We think this kind of ditch bed has many merits and is worth promoting.
