摘　　要：为探讨插前寄秧措施对水稻秧苗素质、产量的影响,黑龙江北大荒农业股份有限公司2020年在16个分公司的试验田开展了水稻插前寄秧试验。结果表明,插前进行寄秧有利于缓苗、增加根量、促进早生分蘖,对产量形成有利;寄秧处理还能减少插后本田空穴少,减少了本田补苗用工量。其中,寄秧4 d的处理效果最好,产量比对照(现起现插)增产7.5 kg/667 m^(2),净增效益48.0元/667 m^(2)。In order to explore the effects of the measures of storing seedlings before transplanting on the seedlings quality and yield of rice,a field experiment was carried out by 16 branches of Heilongjiang Beidahuang Agricultural Co.,Ltd.in 2020.The results showed that storing seedlings before transplanting was beneficial to slow down seedlings,increase root number,promote early tillering,and increase yield.After transplanting,there are fewer holes in the field,which reduces the amount of labor for seedling replenishment.Among them,the effect of storing seedlings for 4 days before transplanting was the best,and the yield was increased by 7.5 kg/667 m^(2) and the benefit was increased by 48.0 yuan/667 m^(2) compared with the control.
