行间生草对玫瑰香葡萄生长及土壤性状的影响

Effects of cover cropping system on the growth of Muscat Hamburg and soil characteristics

本试验通过在玫瑰香葡萄园行间间作中华薄荷、猫薄荷、神香草、紫花苜蓿和清耕处理,探索行间不同生草植物对玫瑰香葡萄生长及葡萄园土壤性状的影响。结果表明:4种行间生草处理玫瑰香葡萄生长量均高于清耕,间作猫薄荷效果最明显。4种行间生草处理土壤有机质含量均高于清耕。不同处理的土壤速效氮含量顺序为:薄荷=对照CK>猫薄荷>神香草>紫花苜蓿。不同处理的土壤速效磷含量的顺序为:薄荷>猫薄荷>紫花苜蓿>神香草>对照CK。不同处理的土壤速效钾含量顺序为:神香草>薄荷=紫花苜蓿>猫薄荷>对照CK。

In order to reveal the effects of cover cropping system on the growth of Muscat Hamburg and the soil characteristics in the vineyard, Mentha haplocalyx, Nepeta cataria, Hyssopus officinalis and Medicago sativa L. were intercropped with the grape vines, respectively, with the clean tillage as the control （CK）. The results showed that the four plants increased the growth of Muscat Hamburg, and N. cataria exhibited the best effect. Under the treatments of cover crops, the contents of organic materials in the vineyard soil were higher than that of the control. The sequences of the contents of available N, P and K in the soil were M. haplocalyx = CK 〉 N. cataria 〉 H. oYficinalis 〉 M. sativa, M. haplocalyx 〉 N. cataria 〉 M. sativa 〉 H. officinalis 〉 CK, H. officinalis - M. haplocalyx 〉 M. sativa 〉 N. cataria 〉 CK, respectively.
