| 摘 要： | 通过对不同钾肥处理条件下小黑麦的地上生物量、地下生物量、株高、粗纤维、粗蛋白和粗脂肪含量的测定,探讨钾肥对拔节期小黑麦生长特性及营养物质含量的影响,为小黑麦钾肥管理提供理论参考。结果表明:小黑麦的地上生物量和地下生物量达到最高值,同时也获得最高株高;施用钾肥能够显著提高小黑麦的粗蛋白、粗纤维和粗脂肪含量(P<0.05),施钾量为0.157g/m2和0.304g/m2时各种营养物质达到最高值;钾肥施用能够显著降低粗灰分含量(P<0.05),当施钾量为0.157g/m2时灰分含量最低。

| Abstract: | Aboveground and underground biomass,plant height,crude fibre,crude protein,crude fat and ash content of triticale were tested under different potassium levels to study effect of potassium on Triticale,to afford reference for potassium management.The results showed:The top value of aboveground and underground biomass,height was obtained crude fibre content,crude protein content and crude fat content was obtain under 0.157g/m2 and 0.304g/m2 level,and the lowest value of ash content under 0.157g/m2 level;And t... |
