摘要
为了寻求适宜的蓝莓套种模式,选择花生、辣椒、毛豆和西瓜4种作物分别与蓝莓进行垄间套种试验,研究套种对蓝莓叶片及土壤氮磷钾含量的影响。结果表明:与对照(未套种)相比,套种不同作物蓝莓叶片中氮、钾含量均有明显增加:与西瓜套种,蓝莓叶片氮含量比对照增加1倍;与辣椒套种,蓝莓叶片钾含量比对照增加50%,且2种作物套种对叶片磷含量影响不显著。与对照相比,套种4种作物均显著降低土壤有机质的含量;套种毛豆可提高土壤的氮含量,套种西瓜可提高蓝莓对磷和钾的吸收利用能力。
Four crops of peanut,pepper,green soybean and watermelon were inter-planted with blueberry respectively to discuss the effect of inter-planting crops on N,P and K content in soil and leaves of blueberry and to probe the optimum blueberry inter-planting pattern.Results：N and K content in leaves of blueberry inter-planted with different crops increases obviously compared with CK.N content in leaves of blueberry inter-planted with watermelon and pepper increases by two times and 1.5times compared with CK respectively and two inter-planting crops of watermelon and pepper have no significant influence on P content in leaves of blueberry.Compared with CK,four crops of peanut,pepper,green soybean and watermelon reduce soil organic matter content significantly.Inter-planting green soybean can increase soil N content and inter-planting watermelon can improve the P and K absorption and utilization ability of blueberry.
