摘要
以小黑麦作为研究材料,通过设置5种不同的秸秆覆盖与镇压处理,在小黑麦的各个生长期对其进行生理指标的测定,研究秸秆覆盖与镇压对小黑麦鲜重和干物质重、株高、次生根、叶片数的影响。试验结果表明:5种处理下小黑麦的生长状况呈现出了:A4>A3>A>A1>A5。而且A4处理下小黑麦的生长状况明显大于其他各组处理下小黑麦的生长。播种前秸秆覆盖后翻地加镇压这种处理对小黑麦的生长影响最大,最有利于小黑麦的生长。秸秆覆盖与镇压对小黑麦生长状况中的株高,鲜重,根长,根数有显著影响,能明显促进小黑麦的生长发育和产量。
With triticale as research material, the effects of five different ways of straw mulching and rolling weight, plant height, leaf number, secondary root number of triticale in every growth stage were studied through a on dry set of determinations of its physiological indices. The results show that the growth conditions of triticale in five treatments were in a order of A4 〉 A3 〉 A 〉 A1 〉 AS. And the growth condition in treatment A4 was significantly better than in other treatments. The treatment of ploughing and rolling following straw mulching before sowing had the greatest impact on the growth of triticale, being most conducive to the growth of triticale. Straw mulching and rolling had significant effects on triticAle growth status, such as plant height, fresh weight, root length and root number, thus obviously promoting the growth and and yield of triticale.
