水稻施用涂层尿素,可改善其生物学性状,增加有效穗数、穗粒数及千粒重。一次性基施、追施涂层尿素,分别比追施普通尿素增产12.6%、6.5%;氮肥利用率比普通尿素提高13.6%和7.0%;基施、追施涂层尿素与普通尿素投入产出比分别为1:9.3、1:8.0、1:6.6。基施可免去追肥步骤,简化农业栽培程序。
Application of urea coating rice can improve its biological properties, increase the effective panicles, grains per spike and 1000-grain weight. One-time foundation facilities and topdressing coating urea increased yields by 12.6% and 6.5% respectively compared with that of general urea; utilization rates of nitrogen fertilizers increased by 13.6% and 7.0% respectively compared with ordinary urea; The input-output ratios of coated urea and ordinary urea were 1: 9.3, 1: 8.0 and 1: 6.6 respectively. Kish Facility eliminates the need for top dressing steps and simplifies agricultural cultivation procedures.
