摘要
利用田间小区试验,以常规化肥和不施肥料为对照,研究了几种新型肥料在一次性基施条件下对晚稻黄华占的生长发育、产量及肥料利用效率的影响。结果表明,与不施肥对照相比,所有参试肥料一次性基施后均能显著提高晚稻产量,其中以施用硫包衣尿素处理的产量和氮磷钾吸收及利用效率最高,经济效益最佳。
To compare the effects of several new fertilizers on growth, yield and fertilizer utilization efficiency of late rice Huanghuazhan, an experiment was carried out in the field. The results showed that, the application fertilizer treatment could improve the yield of late rice compared with CK(conventional fertilizer application). The treatment with sulfur coating urea fertilizer(SCU) had the highest yield and fertilizer absorption and utilization efficiency, the economic benefit was the best.
