| 摘 要： | 黑龙江省北部地区纬度较高,气候寒冷,无霜期短,在该地区种植的大多数晚熟青贮玉米(Zea mays L.)品种尚未达到适宜收获期就被迫收获,造成籽实成熟度差,营养物质含量低,严重影响了青贮饲料的品质,而大多数早熟的玉米品种虽籽实成熟度较好,但生物产量低,不能满足生产需求.将不同生育期的青贮玉米品种以混播方式进行种植,晚熟品种可保证较高的生物产量,早熟品种可提高籽实产量,从而改善青贮品质,达到稳产优质的目的.以晚熟玉米品种中原单32和4个早熟玉米品种龙单13、龙单8、海育9号及海育8号为材料在黑龙江省北部地区进行单播及混播试验,探讨混播对不同品种玉米农艺性状、产量和饲用品质的影响.结果表明:混播对于各品种玉米农艺性状影响不显著;混播显著提高干物质产量和饲用品质(P<0.05);应用Milk 2000粗饲料评价指数分析,中原单32与海育9号的混播组合评价指数最高.

| Abstract: | The north region of Heilongjiang Province is characterized with high latitude,cold weather and short frost-free period.The majority of late-maturing silage corn(Zea mays L.) varieties planted in that region has to be reaped in the inappropriate harvest period resulting in immature seed and low nutrient content and seriously affecting the quality of silage.Although the seed production of most early-maturing silage corn varieties has better maturity,low biomass can not meet the production demand.By mixing sil... |
