一、情况早造早播早植,是增产的一项关键措施。它不仅关系早造的增产,而且关系一年三熟、四熟,造造增产,全年主动的问题。多年来,我县在各地生产斗争和科学实验中,为了达到早播早植增产的目的,曾采用各种育秧方法,如越冬秧等。但由于早春播种季节经常遇到冬、春性寒潮频繁交替袭击,早播往往造成严重的烂秧、死苗,损失大批种子,结果早播不能早植,延误了季节,影响了良种的推广。推广尼龙薄膜育秧后,虽然解决了早播烂秧的一些问题,但也由于薄膜供应有困难,加上成本高,花工多,发展面积也不大。温室蒸汽育秧,是人工加温,利用室内静风、透光、适温、高湿条件下的一种快速育秧 First, the situation As early as early planting and early planting, is a key measure to increase production. It not only related to the early increase in production, but also the relationship between three crops a year, four cooked, creating increased production, the initiative throughout the year. Over the years, our county in various parts of the production struggle and scientific experiments, in order to achieve the purpose of early sowing early planting increased production, have used a variety of seedling methods, such as over-winter seedling. However, as early spring seasons often encounter frequent winter and spring cold alternating alternating attacks, early sowing often result in serious rotten seedlings, dead seedlings, loss of a large number of seeds, the results of early planting can not be early planting, delayed the season, affecting the promotion of elite. Promote nylon film nursery seedlings, although some problems solved early seeding rotten seedlings, but also due to film supply difficulties, coupled with high cost, spend more, the development area is not large. Greenhouse steaming seedlings, artificial heating, the use of indoor static wind, light, temperature and high humidity conditions under a fast seedling
