摘要:
2019和2020年在河西灌区进行玉米/秣食豆间作田间试验,设置7.5(D1)、9.0(D2)、10.5万株·hm-2(D3)3个青贮玉米种植密度,每个种植密度下设置0(N1)、120(N2)、240(N3)、360 kg·hm-2(N4)4个施氮水平,探究种植密度与施氮对饲草产量、品质和氮肥利用的影响。结果表明,两年D2和D3处理的青贮玉米、秣食豆及总体的干草产量、粗蛋白产量显著高于D1,N3和N4处理的青贮玉米及总体的干草产量、粗蛋白产量显著高于N2和N1。所有处理中,D2N3获得了最高的总干草产量,2019和2020年分别为36.16和30.31 t·hm-2。两年随着密度的增加,青贮玉米、秣食豆及总体的粗蛋白、粗脂肪含量呈下降趋势,而粗灰分、中性洗涤纤维、酸性洗涤纤维含量呈增加趋势。随着施氮量的增加,总体粗蛋白、粗脂肪含量增加,而粗灰分、中性洗涤纤维、酸性洗涤纤维含量呈下降趋势。两年D2处理下总体氮含量、氮吸收量和氮肥利用效率显著高于D3,且D2获得较高的氮肥农学效率。N2、N3、N4处理的总体氮含量和氮吸收量显著高于N1,N3处理的氮肥农学效率和氮肥利用效率显著高于N4。所有处理中D2N3获得最高的氮肥利用效率,2019和2020年分别为1.41和0.86 kg·kg-1。因此,该处理是一种河西灌区青贮玉米/秣食豆间作系统适宜的田间管理措施,具有一定推广价值。
