冬灌的作用,有巩固和发展冬前壮苗,促进根系发育的一面,也有易受冻害死苗的一面,特别是不能解决培育冬前壮苗和促进弱苗转化的问题。但是,浇分蘖盘根水,则能弥补冬灌的缺点和不足。一、先从“根”上谈起我们都知道,小麦的全苗、壮苗和年前适量大分蘖,是将来成穗、丰产的基础。分蘖,是壮苗的标志之一。壮苗必先壮根,根深才能叶茂。根系发育不良和没有分蘖的麦苗,本质上都是弱苗。正常的分蘖,同次生根的生长呈正相关。次生根
The role of winter irrigation, there is the consolidation and development of strong seedlings before winter, promote root development side, but also susceptible to cold frost death side, in particular, can not solve the cultivation of strong winter seedlings and to promote the transformation of weak seedlings. However, pouring tiller packing water, you can make up for shortcomings and deficiencies of winter irrigation. First, starting with the “root” talking about We all know that wheat seedlings, strong seedlings and large tiller years ago, is the future ear, the basis for high yield. Tiller is one of the hallmarks of strong seedlings. Strong seedlings must be the first strong root, deep roots to leafy. Malnutrition rooted and non-tillering wheat seedlings, are essentially weak seedlings. Normal tillers, with the secondary root growth was positively correlated. Secondary root
