竹醋基有机酸钙对建兰生长及土壤性质的影响

Effects of organic calcium made by bamboo vinegar on growth of Cymbidium ensifolium and properties of soil

利用竹醋液制备竹醋基有机酸钙,采用对比分析的方法,将不同质量浓度的NaCl、CaCl2溶液和竹醋基有机酸钙溶液作为融雪剂均匀地喷洒到盆栽建兰和采集的土壤上,每天观察建兰的生长状况,并对喷洒盐溶液后的土壤理化性质进行分析。结果显示,3种盐溶液对建兰都有一定影响,其中竹醋基有机酸钙溶液对盆栽建兰影响最小;NaCl、CaCl2溶液对土壤pH值影响很小,而竹醋基有机酸钙溶液会使土壤pH值增大;盐溶液喷洒后的土壤有机质含量和阳离子交换量下降,土壤全N、P的含量下降,但全K表观含量增加;通过比较可知,竹醋基有机酸钙溶液对建兰生长和土壤性质的影响均比NaCl、CaCl2溶液小,并且盐溶液的质量浓度越小,对建兰和土壤环境的影响越小。

The bamboo vinegar was used to produce organic calcium, and different concentrations of NaC1, CaC12 and organic calcium solutions as deicer were sprayed evenly on the potted Cymbidium ensifolium and collected soil, and the growth of Cymbidium ensifolium was observed everyday, and the physical and chemical properties of soil were analyzed. The results indicate that all the 3 types of salt solutions had certain influence on Cymbidium ensifolium, while the organic calcium had less effect on Cymbidium ensifolium than NaC1and CaC12, and both of NaC1 and CaC12 had little effect on the pH of soil while organic calcium increased greatly the pH of soil, and the organic matter and cationic exchange capacity of soil reduced, and the content of total N, P in soil also reduced while the apparent content of total K in soil increased. By above comparison, the effect of organic calcium made by bamboo vinegar on Cymbidiumensifolium and soil was less than that of NaCI and CaC12, in addition smaller the concentration of salt solution was, less the effect of salt solution on Cymbidium ensifolium and soil was.
