2、。BMoZn配合的每角粒數(shù)居各處理首位,每株角果數(shù)居第二,BMo配合的每株角果數(shù)和千粒重處于各處理首位。試驗(yàn)還表明,凡有配施硼的處理,即:BMo、BZn和BMoZn,有利于提高華雙4號(hào)菜籽的含油量;凡配施鋅的處理,即:MoZn、BZn和BMoZn,有利于提高華雙4號(hào)菜籽的蛋白質(zhì)含量。微量元素的各種配合均可降低華雙4號(hào)菜籽的硫甙、芥酸含量;BZn配合具有最高的油酸含量,較低的棕櫚酸、硬脂酸、亞油酸和亞麻酸含量,對(duì)改善華雙4號(hào)菜籽的脂肪酸組分配比最為有利。對(duì)于雙高(高硫甙、高芥酸)油菜,只考慮提高其產(chǎn)
3、量及含油量,以BMo配合較好;而對(duì)優(yōu)質(zhì)的雙低(低硫甙、低芥酸)油菜,其餅粕所含的蛋白質(zhì)可以直接作為動(dòng)物飼料,因此在提高其產(chǎn)量、含油量,改善油分品質(zhì)的同時(shí),還要兼顧其蛋白質(zhì)含量,則以BMoZn配合效果最好。關(guān)鍵詞:硼;鋅;鉬;油菜;產(chǎn)量;品質(zhì)中圖分類號(hào):S14317 文獻(xiàn)標(biāo)識(shí)碼:A 文章編號(hào):1008-505X(2007)02-0318-06EffectsofB,Mo,ZninteractionontheseedyieldandqualityofBrassicanapusWANGLi2hon
