“秧好一半谷”,说明获得水稻高产,育好秧苗是重要的一环。双季晚稻,播插期受前茬早稻收割期的限制,抽穗期受安全齐穗期的限制,且用作双晚栽培的品种多样,要求的适宜播种期也各不相同。若播插期掌握不当,会造成减产或无收。因此,如何在双季稻面积扩大,“双抢”时季节紧的情况下,合理安排品种搭配,并根据品种的特性和移栽的时期,培育适龄壮秧,不违农时,保证双晚有足够的本田营养生长期和安全齐穗,是夺取双季晚稻高产的重要措施,是改变我省双晚低产面貌,实现晚稻超早稻,粮食超纲要的关键。 我省不少地区,在双晚培育适龄壮秧上积累了丰富的经验。由于双晚育秧这一环抓得 “Good seedling half valley”, indicating that access to high-yielding rice, raising seedlings is an important part. The double-season late rice and sowing date are limited by the harvesting period of the former stubble rice and the heading date is limited by the safe heading date. The variety suitable for double-night cultivation also requires different sowing dates. If broadcast improper grasp, will result in reduced or no income. Therefore, under the condition of double cropping season and tight season, we should reasonably arrange the varieties and mix them according to the characteristics of the varieties and the period of transplanting. Honda nutritional growth and security at full harvest, is to seize the double-cropped late rice high yield an important measure is to change my province double-night low-yielding appearance, to achieve late rice super-early rice, food super key. In many areas of our province, we have accumulated rich experience in cultivating young seedlings at double nights. Due to double-night seedling caught in this ring
