| Abstract: | In order to ensure the better utilization of corn straw silage, the variation law of corn straw silage nutritional quality uiner different storage periods was studied.The corn stalk was harvested and ensiled when the grow period reached the 105th day.Seven chemical components of corn straw silage at different storage times from 50 to 290 days were analyzed.The relationship bet ween chemical components and storage periods was studied and the single-element regression models were built.This research achievement can provide scientific basis for rational utilization of silage. |
