  7. The paper adopted the common breeding way by series of mutagen treating to the yeast ' s cell and spheroplast. finally, the excellent mutant 75l 3555 was obtained. its nature of the production was determined and it can product ethanol on the condition of 40 and have high fermentative speed and stable production. on the other hand, the test was made that the best fermentative condition was found. in the malt juice, adding 0. 02 % k + or 0. 03 % a13 + can increase the production strikingly and adding some degree concentration trahalose can increase the production too and cut short the time of taming. in the study of using molasses producting ethanol, we can obtain high productivity contained the following composition : nitrogen source 1. 5 % maize and 0. 075 % ( nh4 ) 2so4

    本實驗以常規的育種方法,通過對酵母細胞懸液和原生質體進行一系列誘變,經過大量的篩選,最終選育出一株耐高溫高產菌株75l _ ( 3566 ) ,並對其進行了生產性能的測定。 75l _ ( 3566 )在40條件下,濃度為20 bx的麥芽汁發酵液中,產酒率高達11 . 5 ,而且發酵速度快,發酵周期可縮短12h ,其生產性能穩定,可以適應大部分以澱粉質為原料的生產廠家的需要。同時本實驗對75l _ ( 3566 )進行了發酵條件優化的初步研究。

The paper summarized the research for the effects of different grazing intensity on grazing behaviour, grazing grass species and productivity of sheep in recent years, the result showed that : there was a negative correlation between the live weight gain per sheep and the grazing intensity, but there was positive correlation between the live weight gain per hectare and the grazing intensity ; feeding intake of sheep decreased when the grazing intensity become heavier ; there was not significant effect of different grazing intensity on sheep breeding indexes ; as long with the grazing intensity become heavier, the feeding time of sheep increased while resting and idling time decreased, but feeding intake per hundred mouths and daily intake reduced while intake velocity increased ; sheep feeding adaptability is relative ; the light grazing was beneficial to promote mutton quality, but mutton quantity and gross economy benefit was low

    摘要根據近幾十年來放牧強度對綿羊放牧行為、採食植物組成和生產性能的影響進行了綜述,得出以下結論:綿羊的個體增重與放牧率之間呈線性負相關,而公頃增重與放牧率之間呈正相關;綿羊的採食量隨著放牧強度的加重而降低;放牧強度對母羊繁殖性能各指標影響差異不顯著;隨著放牧強度的加重,綿羊的採食時間增加,遊走、反芻臥息時間減少;每百口採食量和日採食量減少,而採食速度增加;放牧綿羊的嗜食性是相對的;輕牧有利於提高肉的品質,但是產肉量低,總的經濟效益不高。
