摘要
以小黑麦冬牧70为试验材料,研究不同灌溉定额对小黑麦产量与品质的影响。结果表明,小黑麦株高、绿叶数与灌溉定额之间符合开口向下的一元二次函数关系,在灌溉定额为3960m^(3)/hm^(2)时两者均最大。鲜草量、干物质量和干物质消化率随着灌溉定额的增加逐渐增加。不同灌溉定额对小黑麦生长指标、产量和营养品质影响显著。灌溉定额为3960m^(3)/hm^(2)时,小黑麦粗蛋白、脂肪、粗灰分含量最高,酸性洗涤纤维、中性洗涤纤维含量较低,适口性和相对饲喂价值较好。
Using winter wheat variety Dongmu 70 as the experimental material,this study investigated the effects of different irrigation quotas on the yield and quality of spring wheat.The results showed that the plant height and number of green leaves of spring wheat exhibited a downward opening quadratic function relationship with the irrigation quota,with both reaching maximum values at an irrigation quota of 3960 m^(3)/hm^(2).The fresh grass yield,dry matter yield and dry matter digestibility gradually increased with the increase in irrigation quota.Different irrigation quotas significantly affected the growth indicators,yield and nutritional quality of spring wheat.At an irrigation quota of 3960 m^(3)/hm^(2),spring wheat exhibited the highest crude protein content,fat content and crude ash content,as well as lower acid detergent fiber and neutral detergent fiber content,indicating good palatability and relative feeding value.
