摘要
为了研究云南田、地2种栽培方式对大麦主要品质的影响,选取11个大麦品种分别采用田、地2种方式种植,在收获之后,利用近红外谷物分析仪测定大麦籽粒水分、蛋白质、淀粉和粗纤维含量。分析表明,所有参试大麦品种籽粒的水分、淀粉含量均是田栽培方式比地栽培方式含量低;蛋白质含量则是田栽培比地栽培高;除云大麦9号田栽培的粗纤维含量比地栽培的高外,其他品种均是田栽培的粗纤维含量比地栽培的低。田、地2种栽培方式对大麦籽粒水分、蛋白质、淀粉、粗纤维含量均达极显著影响(P <0.01);田、地2种栽培方式下,六棱和二棱大麦的水分、蛋白质和粗纤维含量均达极显著差异(P <0.01),其中六棱大麦这2种栽培方式籽粒淀粉含量达显著差异(P <0.05),二棱大麦籽粒淀粉含量达极显著差异(P <0.01);栽培方式和棱型均对大麦品质性状有较大影响。
With the purpose of assessing the effects of two cultivation modes on the main qualitative traits of barley in Yunnan,eleven barley varieties were planted with two modes:being planted in an irrigated field and in a rain-fed field.After harvesting,the contents of water,protein,starch,and crude fiber in barley grain were measured by a near-infrared grain analyzer,and were subsequently analyzed.As a result,all tested varieties grown in the irrigated field showed lower water and starch contents,but higher protein content than those in the rain-fed field.While the variety'Yundamai 9'grown in the irrigated field had a higher crude fiber content than that in the rain-fed field,the others grown in the irrigated field consistently had lower crude fiber contents than those in the rain-fed field.The two cultivation modes led to very significant(P﹤0.01)differences in the contents of water,protein,starch,and crude fiber in barley grain.The two cultivation modes caused very significant(P﹤0.01)differences in water,protein,and crude fiber contents in both six-rowed and two-rowed barley varieties.The two modes led to significant(P﹤0.05)differences in starch content in six-rowed barley varieties,and very significant(P﹤0.01)differences in starch content in two-rowed barley varieties.Barley grain grown in the irrigated field has a higher protein content and a lower crude fiber content,which are more suitable for feed barley.Therefore,different barley varieties should be cultivated with different cultivation modes to produce high-quality grain with high contents of specific nutrients.
