Umlawuli Wokukhula Kwezitshalo Zokuphakelwa Kwasefektri i-Paclobutrazol CAS 76738-62-0 Uyathengiswa

Incazelo Yomkhiqizo

I-Paclobutrazol (PBZ) iyi-antioxidant enamandla.Umlawuli Wokukhula Kwezitshalokanye ne-triazole Fungicide. Ingumphikisi owaziwayo we-i-hormone yesitshaloI-gibberellin. Isebenza ngokuvimbela ukwenziwa kwe-gibberellin, inciphise ukukhula kwama-internodial ukuze inikeze iziqu eziqinile, ikhulise ukukhula kwezimpande, ibangele ukuvela kwezithelo kusenesikhathi kanye nokwandisa ukuvela kwembewu ezitshalweni ezifana notamatisi nopelepele.

Ukusetshenziswa

1. Ukutshala izithombo eziqinile elayisini: Isikhathi esihle kakhulu somuthi ngerayisi yiqabunga elilodwa, isikhathi senhliziyo eyodwa, esingezinsuku ezi-5-7 ngemuva kokuhlwanyela. Isilinganiso esifanele sempuphu emanzi engu-15% ye-paclobutrazol singamakhilogremu ama-3 ngehektare ngalinye kanye namakhilogremu angu-1500 amanzi engeziwe (okungukuthi amagremu angu-200 e-paclobutrazol ngehektare ngalinye kanye namakhilogremu angu-100 amanzi engeziwe). Amanzi ensimini yezithombo ayomile, futhi izithombo zifuthwa ngokulinganayo. Ukuhlushwa kwe-paclobutrazol engu-15% kuphindwe izikhathi ezingu-500 kunoketshezi (300ppm). Ngemva kokwelashwa, izinga lokukhula kwesitshalo liyehla, kufezwe imiphumela yokulawula ukukhula, ukukhuthaza ukuhluma, ukuvimbela ukwehluleka kwezithombo, kanye nokuqinisa izithombo.

2. Hlakulela izithombo eziqinile esigabeni samaqabunga amathathu ezithombo ze-rape, sebenzisa u-600-1200g we-15% paclobutrazol impuphu emanzi e-15% ngehektha ngalinye, bese ufaka u-900kg wamanzi (100-200Chemicalbookppm) ukuze ufafaze iziqu namaqabunga ezithombo ze-rape, ukukhuthaza ukwakheka kwe-chlorophyll, ukuthuthukisa izinga le-photosynthesis, ukunciphisa isifo se-sclerotinia, ukuthuthukisa ukumelana, ukwandisa ama-pod kanye nesivuno.

3. Ukuvimbela i-soybean ekukhuleni ngokushesha kunesigaba sokuqala sokuqhakaza, amagremu angu-600-1200 e-15% paclobutrazol impuphu emanzi e-15% ngehektha ngalinye, amakhilogremu angu-900 amanzi (100-200 ppm), bese ufafaza uketshezi esiqwini naseqabungeni lezithombo ze-soybean ukulawula ubude, ukwandisa ama-pod kanye nesivuno.

4. Ukulawulwa kokukhula kukakolweni kanye nokufakwa kwembewu okune-paclobutrazol ejulile efanele kunezithombo ezinamandla, ukwanda kokuhluma, ukuphakama okunciphile, kanye nomphumela okhuphukile wesivuno kukolweni. Hlanganisa amagremu angu-20 e-15% yempuphu ye-paclobutrazol emanzi enamakhilogremu angu-50 embewu kakolweni (okungukuthi 60ppm), kanye nesilinganiso sokunciphisa ukuphakama kwesitshalo esingaba ngu-5% ku-Chemicalbook. Ifanelekela amasimu kakolweni ahlwanyelwe kusenesikhathi anokujula kwamasentimitha angu-2-3, futhi kufanele isetshenziswe lapho ikhwalithi yembewu, ukulungiswa kwenhlabathi, kanye nokuqukethwe komswakama kuhle. Njengamanje, ukuhlwanyela ngomshini kusetshenziswa kabanzi ekukhiqizeni, futhi kungathinta izinga lokuvela lapho ukujula kokuhlwanyela kunzima ukulawula, ngakho-ke akufaneleki ukuyisebenzisa.
