Paclobutrazol ndi chowongolera kukula kwa mbewu ndi fungicide, cholepheretsa kukula kwa mbewu, chomwe chimatchedwanso inhibitor. Ikhoza kuonjezera zomwe zili mu chlorophyll, mapuloteni ndi nucleic acid mu zomera, kuchepetsa zomwe zili erythroxin ndi indole acetic acid, kuwonjezera kutulutsidwa kwa ethylene, kuonjezera kukana kogona, chilala, kuzizira ndi matenda, kuonjezera zokolola, kusintha khalidwe ndi Kupititsa patsogolo. Kuchita bwino kwachuma. Ndiwowopsa kwambiri kwa anthu, ziweto, nkhuku ndi nsomba, ndipo kugwiritsa ntchito kwake pakupanga masamba kumathandizira kwambiri kukulitsa kupanga komanso kukonza bwino.
Kugwiritsa ntchito paclobutrazol mu ulimi
1. Lima mbande zolimba
Mbeu za biringanya, mavwende ndi masamba ena akamakula, mutha kupopera 50-60 kg ya 200-400ppm madzi pa ekala pa tsamba 2-4 kuti mupewe "mbande zazitali" ndikukulitsa mbande zazifupi komanso zolimba. . Mwachitsanzo, polima mbande za nkhaka, kupopera mbewu mankhwalawa kapena kuthirira ndi 20 mg/L paclobutrazol njira pa tsamba limodzi ndi gawo limodzi la mtima la mbande mu thireyi za pulagi kungapangitse mbande kukhala yabwino ndikutulutsa mbande zazifupi komanso zamphamvu.
Powetsa mbande za tsabola, thirirani madzi a paclobutrazol 5 mpaka 25 mg/L pa tsamba 3 mpaka 4 pa mbande kuti mumere mbande zolimba. Powera mbande za phwetekere, thirirani madzi a paclobutrazol 10-50 mg/L pamene mbande zafika pa 2-3 masamba kuti zisakule kwambiri.
Pa tsamba la 3-tsamba la phwetekere yophukira, tsitsani 50-100 mg/L paclobutrazol njira yokulitsa mbande zolimba.
Mu kulima mbande za phwetekere, masamba atatu ndi mtima umodzi amathiridwa ndi 10 mg/L paclobutrazol solution.
Mukautsa mbande za biringanya, tsitsani 10-20 mg/L paclobutrazol solution pamasamba 5-6 kuti mbande zikhale zazing'ono komanso kuti zisakule kwambiri.
Powera mbande za kabichi, paclobutrazol 50 mpaka 75 mg/L paclobutrazol pamasamba awiri ndi mtima umodzi, zomwe zingapangitse kuti mbande zikule mwamphamvu ndikukula kukhala mbande zazifupi komanso zolimba.
2. Yesetsani kukula kwambiri
Musanabzale, zilowerereni mizu ya tsabola ndi 100 mg/L paclobutrazol yankho kwa mphindi 15 musanabzale. Utsi ndi 25 mg/L kapena 50 mg/L paclobutrazol njira za 7 masiku mutabzala; pamene kukula nthawi ndi mphamvu kwambiri, ntchito 100 ~ Kupopera mbewu mankhwalawa 200 mg/L paclobutrazol madzi akhoza kukwaniritsa zotsatira za dwarfing zomera ndi kupewa leggy kukula.
Kumayambiriro kwa kukula kwa nyemba zobiriwira, kupopera mbewu mankhwalawa ndi 50 mpaka 75 mg/L paclobutrazol paclobutrazol kumatha kupititsa patsogolo kuchuluka kwa anthu, kupititsa patsogolo photosynthesis, ndikuletsa kukula kwa miyendo, potero kumawonjezera kuchuluka kwa ma inflorescence patsinde lalikulu ndi 5% mpaka 10%, kukhazikika kwa pod ndi pafupifupi 20%.
Pamene edamame ili ndi masamba a 5 mpaka 6, ikani ndi 50 kwa 75 mg / L ya madzi a paclobutrazol kuti tsinde likhale lolimba, kufupikitsa internodes, kulimbikitsa nthambi, ndikukula mosalekeza popanda kukhala ndi miyendo.
Mbeu ikafika kutalika kwa 40 mpaka 50 cm, ikani 300 mg/L paclobutrazol madzi kuyambira koyambirira kwa Ogasiti mpaka koyambirira kwa Seputembala, kamodzi pa masiku 10 aliwonse, ndikuthira 2 mpaka 3 mosalekeza kuti ikule bwino.
Mbande za phwetekere ziyenera kupopera mankhwala a 25 mg/L paclobutrazol patatha masiku 7 mutamuika; Kupopera mbewu mankhwalawa ndi 75 mg/L paclobutrazol solution mukachedwetsa mbande kungalepheretse kukula kwa miyendo ndikulimbikitsa kukula kwa mbewu.
Pa siteji ya masamba atatu, kupopera mbewu mankhwalawa ndi 200 mg/L paclobutrazol paclobutrazol kumatha kuwongolera kukula ndikuwonjezera zokolola pafupifupi 26%.
3. Kuchulukitsa kupanga
Mu mbande kapena siteji yakukula kwa mizu, tsinde ndi masamba masamba, kupopera mbewu mankhwalawa 50 kilogalamu 200 ~ 300ppm paclobutrazol njira pa ekala akhoza kulimbikitsa thickening masamba masamba, kufupikitsa internodes, zolimba zomera, bwino, ndi kuchuluka zokolola. Mwachitsanzo, musanathyole nkhaka, imbani ndi 400 mg/L paclobutrazol solution kuti muonjezere zokolola pafupifupi 20% mpaka 25%.
Pakadutsa masamba anayi a nkhaka zophukira mu greenhouses, tsitsani madzi a paclobutrazol 100 mg/L kuti mufupikitse ma internodes, phatikizani mawonekedwe a mbewu, ndi kukhuthala zimayambira. Kulimbana ndi powdery mildew ndi downy mildew kumawonjezeka, kuzizira kumakhala bwino, ndipo chiwerengero cha zipatso chimawonjezeka. , kuchuluka kwa zokolola kumafika pafupifupi 20%.
Patsamba la 3-4 la kabichi waku China, kupopera mbewu mankhwalawa ndi 50-100 mg/L paclobutrazol solution kumatha kufooketsa mbewu ndikuwonjezera kuchuluka kwa mbewu ndi 10% -20%.
Pamene radish ili ndi 3 mpaka 4 masamba enieni, ikani ndi 45 mg / L paclobutrazol njira yowonjezera kukana ndi kuchepetsa zochitika; Pamizu ya minofu mapangidwe siteji, utsi ndi 100 mg/L paclobutrazol njira ziletsa zomera kukula. Imalepheretsa kutsekeka, imapangitsa masamba kukhala obiriwira, imapangitsa masamba kukhala afupi komanso owongoka, imathandizira photosynthesis, komanso imathandizira kunyamula zinthu za photosynthetic kupita kumizu yamnofu, zomwe zimatha kuchulukitsa zokolola ndi 10% mpaka 20%, kuteteza chimanga, ndikuwongolera malonda. .
Kupopera mbewu mankhwalawa ndi 100 mpaka 200 mg/L paclobutrazol paclobutrazol madzi pa nthawi yophukira mpaka yophukira kumatha kukulitsa nthambi zogwira mtima, kuchuluka kwa poto ndi kulemera kwa mbeu, ndikuwonjezera zokolola pafupifupi 20%. Pamene mipesa kukwera pamwamba pa alumali, utsi chilazi ndi 200 mg/L paclobutrazol madzi. Ngati kukula kuli kolimba, tsitsani kamodzi pamasiku 5 mpaka 7, ndipo perekani 2 mpaka 3 mosalekeza kuti mulepheretse kukula kwa tsinde ndi masamba ndikulimbikitsa kumera kwa nthambi zam'mbali. Maluwa amakula, ma tubers amakula, ndipo zokolola zimawonjezeka pafupifupi 10%.
4. Limbikitsani zotsatira zoyambirira
Feteleza wochuluka wa nayitrogeni amathiridwa m’munda wa ndiwo zamasamba, kapena ndiwo zamasamba zimadetsedwa ndipo kuwala sikukwanira, kapena chinyezi chamasamba m’dera lotetezedwa chimakhala chokwera usiku, ndi zina zotero, zomwe nthawi zambiri zimayambitsa masamba ndi masamba. kutalika, kumakhudza kakulidwe ka uchembere ndi kakhazikitsidwe ka zipatso. Mukhoza kupopera 50 kg ya 200ppm yamadzimadzi pa ekala kuti muteteze tsinde ndi masamba ndi miyendo, zomwe zimalimbikitsa kukula ndi kubereka msanga. Pa mapangidwe siteji ya minofu mizu, kupopera mbewu mankhwalawa 100-150 mg/L paclobutrazol njira pa masamba, 30-40 malita pa ekala, akhoza kulamulira kukula kwa pamwamba pa nthaka ndi kulimbikitsa hypertrophy ya minofu mizu. Samalani molondola ndende ya mankhwala ndi yunifolomu kupopera mbewu mankhwalawa. Limbikitsani kucha zipatso. Pambuyo fruiting, utsi ndi 500 mg/L paclobutrazol njira ziletsa vegetative kukula ndi kulimbikitsa zipatso kukhwima.
Kusamalitsa
Onetsetsani kwambiri kuchuluka ndi nthawi ya mankhwala. Ngati chomera chonsecho chitapopera, kuti muwonjezere kumamatira kwamadzimadzi, onjezerani mlingo woyenera wa ufa wosalowerera ndale kumadzimadzi. Ngati mlingowo ndi waukulu kwambiri ndipo ndendeyo ndi yochuluka kwambiri, zomwe zimapangitsa kuti mbewu zisamalephereke, mukhoza kuwonjezera kugwiritsa ntchito feteleza wofulumira, kapena gwiritsani ntchito gibberellin (92O) kuti muchepetse vutoli. Gwiritsani ntchito 0,5 mpaka 1 magalamu pa ekala ndikupopera madzi okwana 30 mpaka 40 kilogalamu.
