1: noob hnav khaub ncaws
Cov qoob loo tseem ceeb yog nplej, pob kws, txhuv, thiab ua kom muaj kev hnav khaub ncaws ntsuab, nws yog kev txhawb nqa kev loj hlob ntawm seedlings hauv cov theem tom qab. Qhov kev pom zoo thiab lub sijhawm ntawm kev daws teeb meem yuav tsum tau sau tseg. Cov concentration feem ntau yog feem ntau 1.8% sodium nitrophenolates (atonik) diluted 6000 zaug, thiab lub sijhawm soaking yog 8-12 teev. Tom qab ntawd coj nws tawm thiab qhuav nws ua ntej tseb.
2: Txau thaum lub caij yub thiab theem kev loj hlob
Hais txog cov txau ntawm sodium nitrophenolates (atonik) thaum lub caij yub thiab kev loj hlob los them sai sai rau cov kev loj hlob thiab kev loj hlob. Thaum lub caij cog qoob loo (xws li: nplej li cas, feem ntau xaiv lub sijhawm ntawm ntsuab. Rau mov, ib lub lim tiam tom qab cog). Qhov kev xaiv xaiv yog qhov tseeb 1.8% aqueous daws, diluted 3000 lub sij hawm.
Thaum lub sijhawm kev loj hlob, lub sijhawm tseem ceeb ntawm lub caij nplooj ntoo thiab lub sijhawm puv tau txau ib zaug. Ib qho ntxiv, lub tswv yim tseem ceeb yog 1.8% aqueous daws, diluted 3000 zaus, lossis 2% aqueous kev daws yuav muaj 3500 zaug. Kev ua kom tiav ntawm cov kev sib txawv ntawm cov kev daws teeb meem yog txawv me ntsis.
