用简易诊断法检查判断液压系统各元件的工作性能

故障的排除首先在于判断，目前基层维修网点大多数没有检测仪器和设备，出了故障乱拆乱卸，导致液压元件工作失灵，甚至整车液压系统瘫痪。拖拉机液压系统产生故障的主要原因是液压元件工作性能恶化引起的。为此，介绍了在没有检测仪器和设备的条件下，如何应用简易诊断法检查判断各液压元件的工作性能。

几种代表性牧草对水牛泌乳高峰期生产性能的影响

将36头泌乳期、产奶量相近的水牛均分3组,探讨禾本科黑麦草、豆科紫花苜蓿、蓼科鲁梅克斯K-1三种牧草对泌乳高峰期生产性能的影响,结果发现,饲喂鲁梅克斯K-1分别比紫花苜蓿和黑麦草提高15.93%、13.14%的产奶量(P<0.05),以及6.09%、6.63%的乳脂率(P<0.01);而紫花苜蓿与黑麦草间差异均不显著(P>0.05)。故种植鲁梅克斯K-1适合我国农村散养水牛的小区放牧或舍饲补饲。

Development of Chinese Near-isogenic Line of Rice and Their Differentiating Ability of Pathogenic Races of Blast Fungus

The rice( Oryza L. ) variety, Lijiangxintuanheigu(LTH), is a universally susceptible variety. A set of near-isogenic lines (NILs) of rice which has single resistance gene for each line was developed by use of LTH as recurrent parent and Kusabue,Tsuyuake, K1, PiNo. 4, K60 and BL1, which are from Kiyosawa‘s differential varieties(KDV), as donor parents. Differentiating ability of these NILs to Philippine isolates was compared with that of their donor parents, KDV and IRRI‘ s NILs. The results of comparative studies were as follows: (1) Differentiating ability of Chinese NILs to Philippine isolates was much stronger than that of their donor parents and that of KDV. (2) Chinese NILs had similar ability to differentiate races to IRRI‘s NILs or higher differentiating ability than them. But IRRI‘s NILs almost had no differentiating ability to isolates from japonica rice-growing regions. They can not be used to differentiate races of isolates from japonica ricegrowing regions. Whereas, Chinese NILs can be used to differentiate races of isolates from both japonica ricegrowing regions and indica rice-growing regions. It was concluded that the set of Chinese NILs can be used as international differentials.
