| 摘 要： | 对青贮玉米不同生育阶段全株干物质与青贮营养积累规律、不同器官产量与营养转移规律、全株生物产量积累规律及水分变化规律进行了研究。结果表明,青贮玉米乳熟期鲜产量最高,随着子粒灌浆和成熟度的提高,全株鲜产量及蛋白质含量有所下降,但蜡熟期全株具有较高的干物质产量和蛋白质总量,具有适宜青贮的最佳含水量,蜡熟期全株青贮后NDF和ADF最低,消化率最高,收获加工青贮具有较高的产量和营养价值。

| Abstract: | This experiment studied the accumulation trends of dry matter and nutrition of silage maize at different development stages,the transfer of yield and nutrition in different organs,the accumulation trend of whole organism yield as well as the dynamic of water content.The result showed that fresh yield of whole plant at milk stage was the highest.With the improvement of grain filling and maturity,fresh yield and protein content decreased.However,at dough stage,dry matter and total protein content were higher and water content was optimal for silage,also whole maize silage with ear had the lowest neutral detergent fiber(NDF) and acid detergent fiber(ADF),while it had the highest coefficient of digestibility.It was showed that yield and nutrition value were higher when harvesting and producing silage at dough stage. |
