连作晚稻常因季节的限制,使一部分田成为迟栽田,特别是秧田,插种更迟,产量更低,影响晚稻增产。两年来,我们推广了秧田拔秧留苗技术,基本上解决了这个矛盾,获得了高产。1982年我们在5个大队进行大田定点对比观察,证实拔秧留苗可比移栽秧增产,其幅度达12.5—33.3％(表1),并还可省工省成本,是一项值得推广的增产技术。
Continuous cropping of late rice is often due to seasonal restrictions, so part of the field into a late transplanting, especially seedling, intercropping later, lower yield, affecting late rice yield. In the past two years, we popularized seedling seedling-retaining techniques and basically solved the contradiction and obtained high yields. In 1982, we conducted field-specific comparative observation in 5 battalion groups and confirmed that seedling transplanting seedlings could increase the yield by 12.5-33.3% (Table 1) and also saved the cost of labor-saving. It is worth promoting Increase production technology.
