Kev siv gibberellins hauv kev cog qoob loo, PPM thiab kev siv ntau yam kev hloov pauv

Thaum cov khoom siv dag zog ntxiv cuam tshuam nrog cov teeb meem xws li cov ntsiab lus thiab kev siv ntau, ppm feem ntau qhia. Feem ntau yog hluavtaws gibberellin, nws cov ntsiab lus txawv, qee qhov yog 3%, qee qhov yog 20%, thiab qee qhov yog 75%. Yog tias cov tshuaj no tau muab coj los ua ntau yam uas yooj yim rau txhua tus neeg to taub, yuav muaj teeb meem. Txawm hais tias lawv yog cov concentrated dhau los yog dilute, thiab nws yuav tsis muaj txiaj ntsig.

peb muaj ib txoj kev yooj yim heev los hloov ppm ntau.
Piv txwv li, yog tias koj siv 10ppm concentration ntawm gibberellin los khaws cov txiv hmab txiv ntoo, qhov koj yuav yog 3%, thiab koj yuav tsum siv 10ppm concentration. Nws yog 1 lab muab los ntawm cov ntsiab lus ntawm 0.03, thiab tom qab ntawd muab faib los ntawm 10, qhov concentration uas yuav tsum tau txau yog 3000 zaug, muab faib los ntawm 0.03, 0.03 yog cov ntsiab lus ntawm 3%, thiab muab faib los ntawm cov concentration ntawm 10ppm, xam ntawm no yog 3000 lub sij hawm, 3000 yog tag nrho cov multiples yuav tsum tau.
Piv txwv li, yog tias koj yuav tus neeg sawv cev dej nrog cov ntsiab lus ntawm 4%, koj yuav tsum tau thov 5ppm. Muab 1 lab los ntawm 0.04, thiab tom qab ntawd faib cov txiaj ntsig los ntawm 5, uas sib npaug 8000. 8000 yog qhov xav tau ntau.
