摘要
[目的]对辽河流域棉区棉花饲料化综合利用的潜力进行评价。[方法]以棉花、玉米、大豆为研究对象,采用大区对比法,比较3种作物不同时期的生物量和营养成分(粗蛋白、粗纤维、粗脂肪和淀粉)含量。[结果]3种作物的生物量和干物质积累率随着生育进程而升高,其中玉米的地上部生物量和籽粒产量高于棉花和大豆;玉米的淀粉含量显著较高,棉花和大豆的粗蛋白和粗脂肪含量较高;玉米在3个时期单位面积的纤维素和淀粉含量较高,大豆进入生殖生长之后粗蛋白和粗脂肪含量较高。玉米的生产效益最高,大豆次之,棉花最低。[结论]棉花在各个时期的营养成分虽然都不占优势,但棉花营养均衡、蛋白质和脂肪含量丰富,具有作为畜禽优质饲料的潜力。
[Objective]The aim was to evaluate the potential of comprehensive utilization of cotton for feed.[Method]Taking cotton,corn and soybean as the research objects,the regional comparison method was used to compare the biomass and nutrient content(crude protein,crude fiber,crude fat and starch)of the three crops at different stages.[Result]The results showed that the biomass and dry matter accumulation rates of the three crops increased with the growth process,and the aboveground biomass and grain yield of maize were higher than those of cotton and soybean.The starch content of corn was significantly higher,and the crude protein and crude fat content of cotton and soybean were higher.The content of cellulose and starch per unit area of corn was higher in the three periods,the crude protein and crude fat content of soybean were higher after entering reproductive growth,and cotton was not dominant in all periods.Corn has the highest production efficiency,followed by soybeans and cotton.[Conclusion]Cotton had the potential to be used as a high-quality feed for livestock and poultry due to its balanced nutrition,rich protein and fat content.
