摘 要:通过给蔬菜喷施ECOFLASH液肥,研究其对蔬菜产量品质、土壤环境的影响及用量和喷施比例。结果表明,比农民常规施肥法增产20%,比不施肥对照增产32%~50%不等,但是,会使Vc含量降低20%左右;对土壤环境不产生污染危害;蔬菜产量随ECOFLASH液肥喷施量的增加而增加,当喷施量超过105kg/km2时,则增加甚微。ECOFLASH is a kind of liquid complex fertilizer. This study aimed todetermine the effects of ECOFLASH on the yields and qualities of some vegetables and soilenvironment and fix the suitable dosage and spray concentrations. The results of experimentsshowed that the pakchoi yields in the treatments Ⅰ,Ⅱ, Ⅲ with ECOFLASH application atdifferent doses were 10%, 23% ,25% more respectively than the yield in the CK treatmentwith local conventional fertilizer application or 30%, 48%, 50% more respectively than theyield in the CK treatment without fertilizer application; but the contents of vitamin C inpakchoi in the treatments Ⅰ,Ⅱ,Ⅲ were 19%, 25 %, 17 % less respectively than the content inthe CK treatment without fertilizer application. The application did not cause soilcontamination. The higher the dose of ECOFLASH the higher the yield of pakchoi,but theeconomically suitable is 105 kg/hm2.
