蓝莓盆栽过程中基质的选用是栽培成功的主要物质基础.为了解各基质的养分供应状况,本实验根据北方土壤特点和有机质资源的丰富度设计了lO种混合配方,并跟踪研究了各基质在盆栽过程中有机质、N、P、K的变化情况.结果表明,有机质含量高的配方可提供更多的养分,并有利于N、P、K的持续供应.在配制盆栽基质时应多掺人草炭和沼渣等有机物料.“,”Bases selection is the main substance basis for cultivation success of potted blueberry. To explore nutrition supply of every base and according to soil characteristics and organic matter abundance in the north, 10 mixed formulas were devised. Changes of organic matter, N, P and K were tracked and studied during the process of pot cultivation. The result: the base with high organic matter can supply more nutrition and is of benefit to continuous supplying of N, P, and K; it's better for blueberry to put more organic substances such as peat, biogas residue and so on into bases.
