稻田养萍是自力更生从农业内部解决肥料问题的一个新途径,多年的试验和大田应用都一致证明效果良好。随着稻田养萍面积的扩大,需要的萍种越来越多,搞好红萍越冬,为春繁放养提供足够的萍种就显得特别重要。以往采用的红萍越冬方法多立足于消极保种,萍种成活率低、质量差。能不能创 Paddy field Yangping is a new way of self-reliance to solve the problem of fertilizer from within agriculture, many years of experiments and field applications have consistently proved effective. With the expansion of rice paddies, more and more species are needed. It is especially important to do a good job of harvesting red sandals for winter, and to provide sufficient species for spring stocking. In the past, red-wintering winter methods are based on the passive preservation of species, Ping species survival rate is low, poor quality. Can create
