硫膜和树脂膜控释尿素对小麦产量、品质及氮素利用率的影响
Effects of sulfur-and polymer-coated controlled release urea fertilizers on wheat yield and quality and fertilizer nitrogen use efficiency
摘要
Abstract
A field experiment was conducted to study the effects of sulfur- and polymer-coated controlled release urea fertilizers on wheat yield and its quality, plow layer soil inorganic nitrogen (N) contents, and fertilizer N use efficiency. Compared with traditional urea fertilizer, both sulfur- and polymer-coated controlled release urea fertilizers increased the grain yield by 10.4% -16. 5% , and the grain protein and starch contents by 5. 8% -18. 9% and 0. 3% -1. 4% , respectively. The controlled release urea fertilizers could maintain the topsoil inorganic N contents to meet the N requirement for the wheat, especially during its late growth stage. In the meantime, the fertilizer N use efficiency was improved by 58. 2% —101. 2% . Polymer-coated urea produced better wheat yield and higher fertilizer N use efficiency, compared with sulfur-coated controlled release urea.关键词
