不同水肥管理技术对北五味子产量的影响

Effects of Schisandra chinensis yield in different technologies on water and fertilizer management

通过配方施肥、草炭、滴灌、叶面肥等处理和土壤中不同组分有机质对五味子产量的影响进行分析,阐述了不同水肥管理技术对五味子产量的影响。结果表明,施肥对提高胡敏酸和富里酸作用显著,不同施肥方式之间差异不显著,草炭处理效果极显著;胡敏素含量,只有草炭处理与对照处理达到差异显著,这与草炭处理本身含有胡敏素有关;各个处理的高活性有机质的含量均与对照处理达到显著差异,配方施肥和普通施肥之间的差异不显著,滴灌处理的值最大。由上述结论可知,除高活性有机质外,草炭处理对于增加土壤中有机质含量的作用明显好于其他处理,而配方施肥与普通施肥对于有各种有机质组分开的提高差异不显著。随着土壤中胡敏酸、富里酸和高活性有机质的增加,五味子产量逐渐增大呈现出正向关联且显著相关,可知上述几种有机质均有利于五味子产量的增加。

The experiment is located in northeastern of Heilongjiang Province,Schisandra chinensis medicinal garden of Shangzhi,through the formula fertilizer,peat,drip irrigation,foliar fertilizer,etc.,the impact of treatments on Schisandra chinensis yield was researched.Test set 5 processing,including the four conventional treatments and a blank treatment,through different components of soil organic matter,the correlation between yield and its analysis to clarify the various treatment on the fertility of soil-related indicators and Schisandra chinensis yield impact.The results showed that fertilization and peat treatment on the increase in the total obvious effects of organic matter while the role of normal fertilization was not obvious,fertilization of humic acid and fulvic acid were significant obvious effect,different fertilization methods did not differ greatly,while the peat and others were significant difference.Humin content,only the peat processing and contraposition to achieve the significant difference.Each dealing with a high active organic matter of contraposition treatment reached the significant difference.Peat and other treatments had no significant difference,and the formula fertilization and normal fertilization were no significant difference.The value of drip irrigation treatment was the largest.From the above results,not include highly active organic matter,peat treatment for increasing the role of soil organic matter content significantly better than other treatments,formula fertilization and normal fertilization for the improvement of a variety of organic matter content had no significant difference.With the high activity of soil organic matter,humic acid and fulvic acid increasing.Schisandra chinensis yield was gradually increasing,and significantly showed a positive related associa tion.Schisandra chinensis yield was conducive to the organic matter increase.
