Ezolimo Chemical Plant Growth Hormone Paclobutrazol

I-Paclobutrazol(PBZ) iIsilawuli Sokukhula Kwezitshalokanye ne-triazoleIsikhunta. Ingumphikisi owaziwayo we-hormone yesitshalo i-gibberellin. Isebenza ngokuvimbela i-gibberellin biosynthesis, inciphisa ukukhula kwe-internodial ukuze inikeze iziqu eziqinile, ikhulise ukukhula kwezimpande, ibangele i-fruitet yokuqala kanye nokwandisa imbewu ezitshalweni ezinjengotamatisi nopelepele.

Ukusetshenziswa

1. Ukutshala izithombo ezinamandla erayisini: Isikhathi esingcono kakhulu somuthi werayisi yiqabunga elilodwa, isikhathi senhliziyo eyodwa, okuyizinsuku ezingu-5-7 ngemva kokuhlwanyela. Umthamo ofanele we-15% we-paclobutrazol powder wettable ungamakhilogremu ama-3 ehektheleni namakhilogremu angu-1500 wamanzi engeziwe (okungukuthi amagremu angu-200 e-paclobutrazol ngehektha ngalinye namakhilogremu angu-100 wamanzi angeziwe). Amanzi ensimini yezithombo omisiwe, futhi izithombo zifafazwa ngokulinganayo. I-concentration ye-15%paclobutrazoliwuketshezi izikhathi ezingama-500 (300ppm). Ngemuva kokwelashwa, izinga lokwelulwa kwesitshalo liyancipha, lifinyelela imiphumela yokulawula ukukhula, ukukhuthaza ukulima, ukuvimbela ukwehluleka kwezithombo, nokuqinisa izithombo.

2. Hlakula izithombo eziqinile esigabeni samaqabunga amathathu ezithombo zokudlwengulwa, sebenzisa u-600-1200g ka-15% we-paclobutrazol powder wettable ehektheleni, bese wengeza u-900kg wamanzi (100-200Chemicalbookppm) ukufafaza iziqu namaqabunga e-repeseedlings, uthuthukise i-rape seedlings, uthuthukise i-rape seedlings, uthuthukise i-rape seedlings. i-sclerotinia, ithuthukisa ukumelana, ikhulise ama-pods kanye nesivuno.

3. Ukuze uvimbele ubhontshisi wesoya ukuthi ungakhuli ngokushesha kunesigaba sokuqala sokuqhakaza, amagremu angu-600-1200 ka-15% we-paclobutrazol powder omanzi ehektheleni, u-900 kg wamanzi (100-200 ppm), bese uketshezi lufafaza isiqu neqabunga lezithombo zikabhontshisi ukuze ulawule ubude nokukhiqiza imidumba.

4. Ukulawula ukukhula kukakolweni kanye nokugqoka kwembewu ngokujula okufanele kweI-Paclobutrazolabe nesithombo esiqinile, ukukhula okuthe xaxa, ukuphakama okuncishisiwe, nokwanda kwesivuno sikakolweni. Hlanganisa amagremu angu-20 ka-15% wempushana emanzi ye-paclobutrazol namakhilogremu angu-50 embewu kakolweni (okungukuthi 60ppm), nesilinganiso sokunciphisa ukuphakama kwesitshalo cishe ngo-5% ku-Chemicalbook. Ilungele ukuhlwanyela kusenesikhathi amasimu kakolweni anokujula okungamasentimitha angu-2-3, futhi kufanele isetshenziswe lapho izinga lembewu, ukulungiswa kwenhlabathi, kanye nomswakama kukuhle. Njengamanje, ukuhlwanyela komshini kusetshenziswa kakhulu ekukhiqizeni, futhi kungase kuthinte izinga lokuvela lapho ukujula kokuhlwanyela kunzima ukulawula, ngakho akufanelekile ukuyisebenzisa.
