两段育秧,可以适当延长秧龄,迟插不致早穗,是水田多熟地区早播迟插、解决季节矛盾的一种育秧方法。两段秧的秧苗素质好,如茎基宽,根的活力旺盛,分蘖多,干物质积累多,故易于获得高产。近几年来发展的旱育小苗抛寄,则不但可以减轻寄插的劳动强度,在我们的试验中还较一般寄插的两段秧有所增产。但旱育小苗抛寄的某些技术环节有待完善,尤其是抛寄叶龄大小多有争论。针对这一问题,我们用同一组合与处理,连续于1986、1987两年进行了试验。
Two sections of seedlings, you can extend the seedling age, late plug will not be early, is the early maturity of paddy fields paddling late, to solve the contradiction between the season of a method of seedling. Two seedlings of seedlings of good quality, such as stem wide, robust vitality, more tillers, dry matter accumulation, it is easy to get high yield. In recent years, the development of nursery seedlings throwing, it will not only reduce the labor intensity of the insert, in our experiment than the general two inserted seedlings have increased yield. However, some of the technical aspects of the nursery seedlings to be sent to be improved, especially the size of throwing leaves more controversial. In response to this problem, we use the same combination and processing, continuous in 1986, 1987 two years of testing.
