摘要
为了研究甘蓝型油菜、三叶草、抓地龙3种绿肥对苹果园土壤理化性状的影响,在同一果园进行了3种绿肥影响效果和鲜草产量的对比。结果表明,甘蓝型油菜、三叶草、抓地龙3种绿肥在果园的鲜草产量分别为204.55,77.82,71.15 kg/hm2;3种绿肥作物对果园土壤的理化性状影响效果不同,对果园土壤改良效果为甘蓝型油菜>三叶草>抓地龙草。由此可见,在苹果园种植甘蓝型油菜和三叶草是科学可行、安全有效的,值得推广。
To study the Brassica napus, clover, grasp lumbricus three kinds of green manure on soil physical and chemical properties of the apple orchard, the paper compared the green manure effect and grass yield of three kinds green manure in the same orchard. The results showed that Brassica napus, clover, earthworm catch 3 green manure in orchard grass yield were 205.55, 77.82, 71.15 kg/hm2, respectively. Three kinds of green manure crops had different effects on orchard soil physical and chemical character, soil improvement effect could be described as Brassica napus 〉 clover 〉 lumbricus grass. Thus, it is feasible and safe to plant Brassica napus and clover in apple orchard, and it is worth popularizing.
