摘要
在保护地栽培,高肥力土壤条件下,研究施用天然复合酵素剂SS-200对菠菜、黄瓜生长发育、产量和品质的影响。结果表明:与常规施用化学肥料相比,施用天然复合酵素剂SS-200,有利于菠菜、黄瓜上的生长发育,其叶片数,茎粗,株高都有显著增加;施用天然复合酵素剂SS-200增加了菠菜产量,增产达到24.5%,也提高黄瓜的果实产量,平均1 hm2可以增产13.9%;同时施用SS-200菠菜叶柄中的硝酸盐含量降低了700 mg/L,达到9.2%,而SS-200对黄瓜的可溶性糖和Vc含量影响不大;由于肥料投入的降低及产量的增加,1 hm2菠菜的利润达到55 284元/hm2,黄瓜的利润也达到了67 082元/hm2。
Through protected cultivation, under high fertility soil conditions, the paper studied on effect of Korean natural enzymes SS-200 on qualities and productions of spinage and cucumber. The results showed that SS-200 was benefidal to growth and developments of spinage and cucumber as well as the leaf number, stem diameter and plant height. The productions separately increase 24. 5% and 13.9%. The nitrate content in petiole of spinage decrease 700 mg/L, which was 9. 2%. The application of SS-200 had little influence on soluble sugar and Vitamin C contents in spinage. Because of the reduction of fertilizer input and increasment of yield, profit of spinage reached 55284 yuan per hectare, the value for cucumber was 67082 yuan per hectare.
