今年,前期由于受洪灾影响,晚稻抛秧面积扩大了很多。晚稻抛秧栽培是一项新技术,要想获取高产,在管理上应特别注意落实一些有别于常规晚稻的技术措施。及早追肥。晚稻抛秧由于秧龄弹性小,故一般采用早中熟组合。为了夺取高产,必须保证有足够的有效穂数。如亩产450~500公斤,要求每亩有效穗数达到20~22万,以多穗取胜。早中熟组合感温性强,感光性弱,基本营养生长期短,在8月份高温条件下,发育加快,幼穗分化早,有效分蘖期短。另外,抛秧田基本苗也较移栽田少,只有做到早追肥、促分 This year, due to the impact of the floods in the early stage, the area for throwing rice has expanded a lot. Late rice throwing cultivation is a new technology, in order to obtain high yield, management should pay special attention to the implementation of some different from the conventional late rice technical measures. Early dressing. Late rice throwing seedling elasticity as a result of small, it is generally used in early maturing combination. In order to seize high yields, there must be sufficient effective number of pods. Such as mu produce 450 ~ 500 kilograms, required per acre effective spike reached 20 ~ 220000, with more spike to win. Early maturing combination of strong sense of warm, weak sensitivity, the basic vegetative growth period is short, in August under high temperature conditions, accelerated development, early panicle differentiation, effective tillering period is short. In addition, the basic seedlings thrown seedlings transplanted field less transplanting, only to do early top dressing, promote points
