摘要
探讨了在甜菜栽培中施用新型尿素缓释剂对其产质量的影响。试验结果表明:尿素缓释剂通过对土壤脲酶活性的抑制作用,减少了尿素氮的损失,提高了尿素的肥效,促进了甜菜的生长发育,提高了甜菜产质量,经济效益显著。
The new urea slow-release agent was applied to sugar beet, the experimental results showed that it could inhibited activity of urease, reduced the loss of nitrogen in urea, improved manorial efficiency of urea, induced plant's growth and increased root yield and quality of sugar beet, the economic benefit was remarkable.
