NPE 17-17-17
Compound fertilizer lub teb chaws cov qauv qhia tias cov chiv chiv uas muaj cov tshuaj chlorine yuav tsum tau cim nrog cov ntsiab lus chloride ion, xws li cov tshuaj chloride tsawg (muaj cov tshuaj chloride 3-15%), nruab nrab chloride (muaj chloride ion 15-30%), chloride siab (muaj chloride ion). 30% lossis ntau dua).
Kev siv cov nplej, pob kws, asparagus thiab lwm cov qoob loo uas tsim nyog tsis yog tsuas yog tsis muaj mob, tab sis kuj tseem muaj txiaj ntsig los txhim kho cov qoob loo.
Feem ntau, kev siv cov tshuaj chlorine-based compound fertilizer, haus luam yeeb, qos yaj ywm, qos yaj ywm qab zib, txiv tsawb, txiv hmab txiv ntoo, qab zib beets, cabbage, peppers, eggplant, soybeans, lettuce thiab lwm yam qoob loo tiv taus cov tshuaj chlorine muaj kev cuam tshuam tsis zoo rau kev tawm los thiab zoo, tiag. txo cov txiaj ntsig kev lag luam ntawm cov qoob loo zoo li no.Nyob rau tib lub sijhawm, chlorine-based compound fertilizer nyob rau hauv cov av los tsim ib tug loj tus naj npawb ntawm chlorine ion residues, yooj yim ua rau av consolidation, salinization, alkalinization thiab lwm yam undesirable phenomena, yog li deteriorating cov av ib puag ncig, kom cov qoob loo assorption muaj peev xwm. txo.
