浙江省自1955年大面积推广双季连作稻以来,多用原为单季或间作晚稻的品种作连作晚稻栽培,而以延长秧田期的办法,克服本田生育期不足的矛盾。因此,培育稀播壮秧成为提高连作晚稻产量的关键性措施之一。近年来,各地为了培育粗壮秧,又因地制宜地创造了多样化的育秧方法,连作晚稻的育秧技术有了很大的发展。但是,在部分地区对稀播壮秧是否有增产效果、是否有利于提高全年产量和增加
Zhejiang Province since 1955 a large area to promote double cropping continuous rice, the use of more of the former single cropping or intercropping late rice varieties for continuous cropping late rice, but to extend the seedling period approach to overcome the shortage of Honda growth period contradictions. Therefore, nurturing seedling planting thinning has become one of the key measures to improve crop yield. In recent years, in order to cultivate thick seedlings everywhere, and according to local conditions to create a diversified seedling cultivation methods, even as a late rice seedling technology has made great progress. However, whether there will be any increase in the production of sprouted seedlings in some areas will help increase the annual output and increase
