摘要
利用田间小区试验,以不施肥为对照,研究不同类型的肥料一次性基施对双季稻产量和氮肥利用的影响,结果表明:不同肥料品种一次性基施后均能显著提高水稻产量。以施用包膜控释尿素SCU的产量最高,氮素吸收利用效率最高,经济效益最好,其次为金正大肥和袁氏肥,普通速效化肥效果最差。
Through field plot tests with CK( no fertilizer application),we studied the effects of one- off basal application of different types of nitrogen fertilizer varieties on the yield of double- cropping rice as well as the utilizing rate of nitrogen fertilizer.The results indicated that the one- off basal application of tested all nitrogen fertilizer varieties could increase the yield of double-cropping rice significantly. The treatment of applying SCU obtained the highest rice yield,the highest nitrogen- utilizing rate and the best economic benefit,followed by the treatments of applying Jinzhengda fertilizer and Yuan's fertilizer,and the application of common available chemical fertilizer got the worst results.
