蓝莓对土壤pH值的特殊要求以及对部分肥料的敏感,限制了某些肥料在生产中的使用,为了探讨氮、磷、钾在蓝莓生长发育过程中的作用和影响,以8年生的‘灿烂’(Brightwell)为材料,采用“3414”进行施肥处理,结果表明:配方施肥能有效提高土壤中的水解氮、有效磷、速效钾含量;施用酸性肥料,可以降低土壤pH值;最佳施肥组合(N ∶ P ∶ K)配比是2 ∶ 1 ∶ 1,施肥方案为:N 20 ~ 24g/株,P_2O_5 10 ~ 12 g/株, K_2O 10 ~ 12 g/株(折合N 80 ~ 96 kg/hm~2,P_2O_5 40 ~ 48 kg/hm~2,K_2O 40 ~ 48 kg/hm~2)。

Blueberries are sensitive to certain fertilizers and soil pH value, limits the use of certain fertilizers in production. In order to investigate the effects of N, P and K on the growth of blueberry, the 8-year-old Brightwell were treated by formulated fertilization of “3414”. The results showed that formula fertilization not only can effectively increase the content of hydrolyzed nitrogen, available phosphorus and available potassium in soil, but also can promote plant growth significantly. And the application of acid fertilizer can reduce th...
