I-Hormone Yokukhula Kwezitshalo Zamakhemikhali Yezolimo i-Paclobutrazol 15%WP 20%WP 25%WP

I-Paclobutrazol(PBZ) iyi-Umlawuli Wokukhula Kwezitshalokanye ne-triazoleUkubulala isikhunta. Kungumphikisi owaziwayo we-hormone yesitshalo i-gibberellin. Isebenza ngokuvimbela i-biosynthesis ye-gibberellin, inciphise ukukhula kwama-internodial ukuze inikeze iziqu eziqinile, ikhulise ukukhula kwezimpande, ibangele ukuvela kwezithelo kusenesikhathi futhi ikhulise ukuvela kwembewu ezitshalweni ezifana notamatisi nopelepele.

Ukusetshenziswa

1. Ukutshala izithombo eziqinile elayisini: Isikhathi esihle kakhulu sokwelapha ilayisi yiqabunga elilodwa, isikhathi senhliziyo eyodwa, esingezinsuku ezingu-5-7 ngemva kokuhlwanyela. Isilinganiso esifanele sempuphu emanzi engu-15% ye-paclobutrazol singamakhilogremu angu-3 ngehektare kanye namakhilogremu angu-1500 amanzi engeziwe (okungukuthi amagremu angu-200 e-paclobutrazol ngehektare kanye namakhilogremu angu-100 amanzi engeziwe). Amanzi ensimini yezithombo omisiwe, futhi izithombo zifafazwa ngokulinganayo. Ukuhlushwa okungu-15%i-paclobutrazolkuphindwe izikhathi ezingu-500 kunoketshezi (300ppm). Ngemva kokwelashwa, izinga lokunwebeka 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 ngokujula okufaneleI-Paclobutrazolinezithombo ezinamandla, ukukhula kwe-tillering, ukuphakama okunciphile, kanye nomphumela wesivuno okhuphukile kukolweni. Hlanganisa amagremu angu-20 e-15% paclobutrazol wettable powder namakhilogremu angu-50 embewu kakolweni (okungukuthi 60ppm), kanye nesilinganiso sokunciphisa ukuphakama kwesitshalo esingaba ngu-5% ku-Chemicalbook. Ifanelekela ukuhlwanyela amasimu kakolweni kusenesikhathi ngokujula kwamasentimitha angu-2-3, futhi kufanele isetshenziswe lapho ikhwalithi yembewu, ukulungiswa kwenhlabathi, kanye nokuqukethwe komswakama kuhle. Njengamanje, ukuhlwanyela ngomshini kusetshenziswa kakhulu ekukhiqizeni, futhi kungathinta izinga lokuvela lapho ukujula kokuhlwanyela kunzima ukukulawula, ngakho-ke akufaneleki ukuyisebenzisa.
