| The problem of serious rotten in native grass hay bale during storage, select native mineral–CaO as Inhibitor, added it's solid and liquid dosage-form, added solid dosage: 1%, 2%, 3%;liquid dosage: 1%.Studied on the different dosage-form, dosage of Inhibitor in mold prevention and it's Influence on hay bale Quality. Research on the mold fungus, TDN and RFV of hay bale, discussed the feasibility of CaO as inhibitor in native grass, added the suitable dosage, mold-prevening aging property and suitable combination between inhibitor, density, and moisture content. The results are as follow.①The results showed that it is feasible to add suitable inhibitor in hay bale.②At the beginning of storage, the temperature of bale changed with adding different dosage of inhibitor, The temperature of bale with adding 3%CaO was the lowest all of them, The temperature of bale with adding 2%CaO followed.③Added solid inhibitor better than liquid inhibitor in mold prevention. there was less mold fungus, high content of TDN, RFV in Adding 2%CaO(solid)( p<0.05).④1%,2%,3%CaO had inhibition of mildew after storing 90days, after one year later, 2%,3%CaO had inhibition of mildew.⑤After one year later, the hay bale with 20% moisture content, 100kg/m3, added 2%CaO was the best.Hay bales with moisture content, density, added inhibitor, prevent them to go moldy, are good for preserving their nutrition during storage. |
