前言我省现行的水稻直播栽培,基本是属于深水淹灌的传统水直播生产体系,其措施不利于保苗、壮苗,产量不高不稳。针对这一问题,我们开展了有利于保苗、壮苗、灭草和促进早熟高产的“直播水稻苗期湿润灌溉壮苗栽培技术”的研究(以下简称湿润直播),这项研究经过四年小区试验和两年中间试验,证明对保苗、壮苗、灭草和促进早熟均
Preface The current direct seeding cultivation of rice in our province basically belongs to the traditional water direct-seeded production system for deep-water flooding irrigation. The measures are not conducive to maintaining seedlings and strong seedlings, and the yield is not high and unstable. In response to this issue, we conducted a study on “strong seedling cultivation techniques for wetting and direct irrigation of rice at seedling stage” (hereinafter referred to as wet direct seeding) in favor of seedling, strong seedling, herbicide and high yield of early maturity. After four years of study, Trials and two-year pilot studies have demonstrated that seedlings, strong seedlings, herbicides, and precocious pomosis are all proven
