为确定巡青938玉米品种不同收获期秸秆的营养价值,对其秸秆开展化学成分分析和体外干物质消化率测定。结果显示,巡青938玉米品种秸秆在籽粒3/4乳线期时营养价值最高,这一特性与制作青贮玉米一般以籽粒3/4乳线期收获为宜相一致。
In order to determine the nutritional value of straw during the different harvest phases of patrol 938 maize varieties, chemical composition analysis and in vitro dry matter digestibility of the straw were carried out. The results showed that straw 938 maize varieties in the highest nutritional value when the 3/4 milk stamen grain, this characteristic and the production of silage corn is generally 3/4 milk grain harvest phase is appropriate.
