Harvesting Time and Mixing Ratio of Whole Plant Soybean and Maize
In order to determine the best harvest time of whole soybean silage,we prepared the best proportion of whole soybean and maize mixed silage,harvested different varieties of soybeans in different growth stages,tested the forage value,and determined the best harvest period by comparison.Maize and Pudou 5110 were mixed silage according to fresh-weight ratio1∶0,3∶1,2∶1,1∶1,1∶2,1∶3,0∶1,and the feed quality of mixed silage was determined,and the quality of mixed silage was evaluated by component analysis and fuzzy membership function to select the most suitable mixing ratio.The results showed that the feeding quality,fermentation quality and energy value of mixed silage with ratio of 1∶1 were the highest,and the relative feeding value was the best under this treatment.At the same time,the membership function shows that the comprehensive score of 1∶1 mixture is 0.78,and the comprehensive performance is the best.The results showed that the best silage effect was obtained from whole soybean harvested at the end of pod stage or early drum stage and whole maize from 1/2 to 1/3 milk line area at a ratio of 1∶1.
