| 摘 要： | 为提高秸秆粗蛋白含量,以氢氧化钠、过氧化氢、生石灰、熟石灰、尿素为处理剂,进行不同浓度和不同组合方式处理小麦秸和莜麦秸的试验.结果表明:尿素与氢氧化钠的组合对提高秸秆粗蛋白含量极为有效,5%以上的生石灰与尿素组合提高效率最高,为单纯5%尿素氨化法的4倍.建议生产中根据需要确定尿素剂量.

| Abstract: | To effectivelyincrease the crude protein content of the straw,sodiumhydroxide,hydrogen perox-ide,quickli me,urea were used as the treatment agentsinthe experi ment with different densities and combi-nations treating wheat strawand strawof naked oats.The resultsindicatedthat :combination of urea and so-da had very high effect of increasingthe crude protein content in straw,combination of over 5 percent quickli me and urea hadthe highest efficiency,4 ti mes of that of the ammoniation method with5 percent urea only.Determining urea density accordingto the needin practical situation was reccommended. |
