为了开发利用格尔木地区丰富的芦苇资源,1989年7—11月在格尔木园艺场进行芦苇一般青贮、半干青贮试验。经感官鉴定和实验室鉴定结果表明:①芦苇糖分含量高,水分含量适宜,只要适时刈割,调制方法得当,就能制成优良的青贮饲料。②通过凋萎处理,将青鲜芦苇含水量降至45%左右时进行半干青贮,可以显著改善芦苇青贮品质,干物质、蛋白氮含量分别比一般青贮高51.5%和45.7%。
In order to develop and utilize the rich reed resources in Golmud region, reed general silage and semi-dry silage tests were conducted at Golmud Horticultural Field from July to November 1989. Sensory identification and laboratory identification results show that: ① reed sugar content is high, suitable moisture content, as long as timely cutting, modulation method properly, you can make good silage. (2) Semi-dry silage with the water content of fresh reed reduced to about 45% by wilting treatment could significantly improve the quality of reed silage, and the dry matter and protein nitrogen contents were 51.5% and 45.7% higher than that of normal silage.
