Kev sib piv ntawm cov nroj tsuag tus tswj uas tuaj yeem siv los tswj kev loj hlob hauv nplej cog

Hauv cov nplej cog qoob loo, ntau dhau kev loj hlob ntawm cov kav thiab cov kab mob kis tau, ua rau muaj kab mob siab "thiab Fusarium Wilt, uas cuam tshuam nrog cov hmoov nplej thiab tawm tsam.

1. Kev sib piv ntawm peb cov ntsiab lus ntawm kev loj hlob ntawm kev tswj PGR
1. Kev ntsuas kev ruaj ntseg: Uniconazole muaj tus nqi khaws cia ntawm> 85% nyob rau hauv ph5.0-7.5 ib puag ncig, thiab paclobutraigazol (Paclo) decoster thaum raug rau lub teeb muaj zog

2. Tawm nce cov nyhuv: qhov tseem ceeb ntom rau mepiquat chloride kom nce tawm los ntawm 12.3% yog 280,000 pob ntseg / m mu

3. Cov ntaub ntawv txaus ntshai tiv thaiv: hauv qab qhov kub (> 35 ℃), cov txiaj ntsig ntawm uniconazole tsawg los ntawm 62% txo qis los ntawm kev ua haujlwm hauv 78% kev ua si

2. Kev tsom xam ntawm cov yam ntxwv ntawm peb hom ntawm cov ntsiabSibx
1. Uniconazole (25% Wettable hmoov)
- Sijhawm ntawm kev ua tau zoo: 45-60 hnub (kev pab cuam tshuam)
- Chiv Li Cas Cov Phug: Txhawb Nqa Nitrogen Kev Ua Tau Zoo Los ntawm 27%
- Cov Ntaub Ntawv Raug Raug: Shandong Dezhou Tshawb Fawb tau thov ntawm 3-nplooj theem, thiab cov nroj tsuag qhov siab tau tswj tsis pub dhau 70cm

- taboos: Zam kev sib xyaw nrog tooj liab uas muaj foliar fertilizers, thiab kev phom sij index ntawm kev siv kub thiab kev vaum siab yog> 4


2. Paclobutrazol (Paclo) (15% Wettable hmoov)
- Cov yam ntxwv faib hluav taws xob faib: cov av muaj sijhawm ntev txog 210 hnub
- Lub teeb rhiab heev: Cov tshuaj uas ua tau zoo rau kev noj qab nyob hauv qab lub teeb ncaj qha mus txog 0.8% ib teev

- Cov txiaj ntsig nyiaj txiag: Daim ntawv thov nqi rau ib mu yog tswj nyob rau hauv ntau ntawm 8-12 yuan
- Siv cov xwm txheej muaj feem: Mid-thiab lig-theem kev loj hlob tswj (los ntawm kev sib koom ua ke rau khau raj theem)


3. Mepiquat Chloride (20% Sodium allyl sulfonate)
- Mekas Inhibition Inhibition
- Kev sib cuam tshuam: sib xyaw nrog cov poov tshuaj dihydrogen phosphate tuaj yeem nce lub sijhawm los ntawm 15 hnub
- Kev Nyab Xeeb Kev Nyab Xeeb: Nres siv 21 hnub ua ntej sau
- Kev Siv Tshiab: Qhov Pom Zoo Siv Tag Nrho Cov Txau Drone yog 0.8-1.2ml / m mu

III. Txoj kev tsib-kauj ruam rau cov ntawv thov tshuaj tua kab
1. Kev kuaj mob: Qhov siv tau zoo> 18 / cog thiab nroj tsuag qhov siab> 1.2m

3. Cov ntawv thov sib xyaw sib xyaw: Uniconazole + Potassium Dihdogen phosphate = 3: 1 (qhov hnyav piv)

4. Ua Haujlwm Ua Haujlwm Tsis Zoo: Davhlau ntau dua 50m, Nrog tus nqi 120ml / m mu

5. Thaum Kawg Ntsej Muag Me Nyuam: Thaum av noo noo ntau dua 25%, kev pom zoo ntawm cov tshuaj ua kua xav tau hloov kho los ntawm 30%
