Study On Technology Of Modulating Top-quality Xin Jiang Small Reed Silage

It is an important step for technology of reed silage to improve the rate of usage of as well as promote Xin jiang liverstage. It was carried out to study the technology of modulating reed silage in the local condition.The following experiments were done in experiment.ExpⅠ: The result indicated that, pH changes of the different period of growing, the fresh silage directly, its quality was very poor, at that time adds formic acid(3.0ml) treatment ,its quality was best. The CP content change were following that,In the same period of growing time of reed ensilage crude protein (cp) is bigger than the control group (raw material grass) (P<0.01). The NDF and the ADF change was rises gradually according to period of growing, but the ADF content does not have the remarkable changes in the treatments.In the sum, The reed ensilage adds to the formic acid (Chemical additive) may be reduce the pH value which enhance to ensilage quality. Reed's best harvesting time to make the ensiling is the period of earing period; The best kind of ensiling ways was the fresh grass +3.0ml formic acid /kg。.ExpⅡ: The result indicated that, in the same period of growing, the decline of pH of the wilted hay + formic acid treatment were quickly and fermentation quality was best, of the wilted silage were slowly, its fermentation quality was very poor, (P < 0.05).On the CP , the different treatments in the same growing period compared to control group were significantly(P<0.05)increase. In the sum, the reed ensilage adds to the formic acid(Chemical additive)may be reduces the pH which enhance to fermentation quality, It was a kind of ideal additive in the ensiling. The best harvesting time to make the wilted-silage was the period of the earing period; The best kind of treatment was The wilted hay +3.0ml formic acid /kg。ExpⅢ: The results showed that:①DM degradability of hay of the the earing period were higher than that in the florescence and the form seed period respectively (p<0.05).②In the same growth period, The degradability of the NDF of the fresh silage were higher than that the other treatments(p<0.01).③In the same growth period, The degradability of the ADF of the silages were higher than that hay(p<0.01).In the sum, the earing period was a good time for making silage.ExpⅣ: The result of palatability shows that the silage of the earing period wilted hay+3.0ml formic acid/kg or 15.0 g molasses/kg,and the florescence fresh hay+15.0g molasses/kg were superior to others treatments.
