The article concatenates high oil maize growth with livestock breeding.The effect on growth of cattle and cows which were fed on fresh straw,silage straw,integrated fresh straw and integrated silage straw respectively is studied,and all the straw is the straw of Highoil No.115.Results as follows:(1)All the cattle fed on high oil silage maize straw exhibit that the their speed of taking food is higher,body appearance is better compared with those fed on common maize straw, and weight enhances 0.15~0.30 kg per day,and enhances 15%~30% than those fed on common maize straw.(2)It has signalized influence when the milk cows were feed on high oil maize straw,daily milk yield enhanees 1.8 kg every cow,and enhances around 8%.The milkability increases sharp when the congener cattle were fed on high oil maize straw,and their milkability still keeps leading when the high oil maize straw is substituted by common maize straw at the back stage.(3)It signalizes that quality of milk is improved when the milk cows were fed on high oil maize straw.The lactose,butterfat rate,lactoproteid content in milk produced by the crows fed on high oil maize straw increase around 5%,and the milk quality improves a grade than those fed on common maize straw.
"九五"以来,我市畜牧业发展迅速,尤其是草食畜大幅度增加,对优质粗饲料的需求日益迫切.本文从高油玉米种养结合出发,研究高油115整株青贮对肉年增重的影响效果.
紧实坚硬的犁底层对土壤可耕性和理化性质产生极为不利的影响,既阻碍了根系向下伸展,又影响到根系对养分和水分的吸收,降低了玉米的抗倒伏性。同时由于土壤通透性差,也影响到土壤蓄水保墒能力,使雨季大量的降水白白浪费摔。因此研究深松对土壤以及玉米生长效应是十分必要的。
1998~1999年连续进行大面积玉米软盘育苗移栽示范,结果表明,正常年景,移栽玉米可比同期夏直播玉米增产150~200kg,在1999年特殊干旱年份,5000亩移栽玉米亩产达633kg,比同期夏直播玉米亩增产287kg.通过2年的实践研究,我们摸索出了与其相配套的栽培技术,其重点是掌握育苗和移栽2个技术环节:
