塑料薄膜旱育苗(简称旱苗)是培育水稻壮秧,抗御低温冷害,实现稳产高产的重要措施。但是,旱育苗极易发生立枯病,是推广这项育苗技术的障碍。1974～1978年,我们参照国内外培育旱苗的技术经验,开展了水稻塑料薄膜旱育苗技术及防治立枯病的研究,获得了一定成果,并先后在全省重点稻区进行多点试验,示范推广。目前,全省旱苗插秧面积已达二百万亩。兹将研究结果报告如下。
Plastic film drought nursery (dry seedlings) is to cultivate rice seedlings, to resist cold damage, to achieve stable and high yield of important measures. However, dry nursery stock is extremely susceptible to blight and is a barrier to the promotion of this nursery. From 1974 to 1978, with reference to the technical experience of cultivating dry seedlings both at home and abroad, we carried out the research on rice plastic film drought nursery technology and the prevention and control of blight. Some achievements were obtained. In the past several years, Demonstration promotion. At present, the province’s dry seedling transplanting area has reached 2 million mu. The research results are reported below.
