| 摘 要： | 兔巴氏杆菌病是由多杀性巴氏杆菌引起的兔的多种症候性传染病。临诊上表现为鼻炎、地方流行性肺炎、全身性败血症、中耳炎、结膜炎、子宫蓄脓、睾丸炎等不同的病型。本病一年四季都可发生,但以冬春为高发季节,各种日龄的兔都可感染。消化道、呼吸道以及皮肤、粘膜伤口是感染的主要途径。本病是引起2￣6月龄兔死亡的主要原因之一。

| Abstract: | The paper showed that Silicon fertilizer could affect nodules,but did not affect the crude protein content during the branching and maturity stages,nor K in the branching stage,but it did affect the content of K in leaf and stem during the budding stage.K contents of alfalfa root were not significantly different from the control during the budding periods.Ca contents of alfalfa were increased by fertilizing with silicon,but the underground Ca contents were reduced at branching stage.Ca contents of leaves,stem and root were not different from the control in the late bud stage.Alfalfa benefited from the use of silicon fertilization,and Ca,Al,Mg and P were also important in alfalfa.The relationship of silicon and other nutrient components of alfalfa had been indicated in this paper. |
