I-Paclobutrazol ngumlawuli wokukhula kwezityalo kunye ne-fungicide, i-retardant yokukhula kwezityalo, ebizwa ngokuba yi-inhibitor. Inokunyusa umxholo we-chlorophyll, iprotheyini kunye ne-nucleic acid kwisityalo, ukunciphisa umxholo we-erythroxin kunye ne-indole acetic acid, ukwandisa ukukhululwa kwe-ethylene, ukwandisa ukumelana nokulala, isomiso, ukubanda kunye nezifo, ukwandisa isivuno, ukuphucula umgangatho kunye nokuphucula. ukusebenza kakuhle kwezoqoqosho. I-low-toxic kubantu, imfuyo, iinkukhu kunye neentlanzi, kwaye ukusetyenziswa kwayo kwimveliso yemifuno kudlala indima ebalulekileyo ekwandiseni imveliso kunye nokuphucula umgangatho.
Ukusetyenziswa kwe-paclobutrazol kwezolimo
1. Lima izithole ezomeleleyo
Xa izithole ze-eggplants, i-melon kunye neminye imifuno ikhula imilenze, unokutshiza i-50-60 kg ye-200-400ppm ulwelo ngehektare nganye kwinqanaba le-2-4 lamagqabi ukukhusela ukubunjwa "kwezithole ezide" kunye nokuphuhlisa izithole ezimfutshane kunye ezinamandla. . Ngokomzekelo, xa uhlakulela izithole zekhukhamba, ukutshiza okanye ukunkcenkceshela nge-20 mg / L isisombululo se-paclobutrazol kwiqabunga le-1 kunye nenqanaba lentliziyo ye-1 yezithole kwiiplagi zeeplagi kunokuphucula umgangatho wezithole kunye nokuvelisa izithole ezimfutshane kunye ezinamandla.
Xa ukhulisa izithole zepepile, fafaza nge-5 ukuya kwi-25 mg/L ye-paclobutrazol engamanzi kwinqanaba lama-3 ukuya kwamane egqabi lezithole ukuze ukhule izithole ezomeleleyo. Xa ukhulisa izithole zetumata, fafaza nge-10-50 mg/L ye-paclobutrazol engamanzi xa izithole ziku-2-3 isigaba samagqabi ukuze unciphise izityalo kwaye uthintele ukuba zingakhuli kakhulu.
Kwinqanaba le-3 leqabunga le-tomato ekwindla, fafaza nge-50-100 mg / L isisombululo se-paclobutrazol ukuhlakulela izithole ezinamandla.
Kwiplagi ye-tomato ukulima isithombo, amaqabunga ama-3 kunye nentliziyo ye-1 ifafazwe nge-10 mg / L isisombululo se-paclobutrazol.
Xa ukhulisa izithole ze-eggplant, fafaza nge-10-20 mg/L yesisombululo se-paclobutrazol kumagqabi ama-5-6 ukuze unciphise izithole kwaye uthintele ukuba zingakhuli kakhulu.
Xa ukhulisa izithole zekhaphetshu, fafaza i-paclobutrazol eyi-50 ukuya ku-75 mg/L kumagqabi ama-2 kunye nentliziyo enye, nto leyo enokwenza ukuba izithole zomelele kwaye zikhule zibe zizithole ezimfutshane neziqinileyo.
2. Lawula ukukhula ngokugqithiseleyo
Ngaphambi kokutyala, gcoba iingcambu zepepper nge-100 mg / L isisombululo se-paclobutrazol imizuzu eyi-15 ngaphambi kokutshintshwa. Gcoba nge-25 mg / L okanye i-50 mg / L isisombululo se-paclobutrazol malunga neentsuku ezi-7 emva kokutyala; xa ixesha lokukhula linamandla kakhulu, sebenzisa i-100 ~ Ukutshiza i-200 mg / L ye-paclobutrazol engamanzi inokufezekisa umphumo wezityalo ezincinci kunye nokuthintela ukukhula kwemilenze.
Kwinqanaba lokuqala lokukhula kweembotyi eziluhlaza, ukutshiza nge-50 ukuya kwi-75 mg / L ye-paclobutrazol engamanzi kunokuphucula ubume babemi, kuphucule i-photosynthesis, kwaye kuthintele ukukhula kwemilenze, ngaloo ndlela kwandisa inani le-inflorescences kwisiqu esiphambili nge-5% ukuya kwi-10% kwaye umyinge wokumisela i-pod malunga ne-20%.
Xa i-edamame inamaqabunga ama-5 ukuya kuma-6, yitshiza nge-50 ukuya kwi-75 mg / L ye-paclobutrazol engamanzi ukwenza iziqu zomelele, zifinyeze i-internodes, zikhuthaze i-branching, kwaye zikhule ngokuqhubekayo ngaphandle kokuba nemilenze.
Xa ubude besityalo buyi-40 ukuya kwi-50 cm, fafaza i-300 mg / L ye-paclobutrazol engamanzi ukususela ekuqaleni kuka-Agasti ukuya ekuqaleni kukaSeptemba, kanye ngeentsuku ezili-10, kwaye utshize amaxesha amabini ukuya kwe-3 ngokuqhubekayo ukulawula ukukhula.
Izithole zetamatato kufuneka zitshizwe nge-25 mg / L isisombululo se-paclobutrazol malunga neentsuku ezi-7 emva kokutshintshwa; ukutshiza nge 75 mg/L paclobutrazol isisombululo emva kokucothisa izithole kunokuthintela ukukhula kwemilenze kwaye kukhuthaze ukukhula kwezityalo.
Kwinqanaba le-3-leaf, ukutshiza i-moss yolwandle kunye ne-200 mg / L ye-paclobutrazol engamanzi inokulawula ukukhula okugqithisileyo kunye nokwandisa isivuno malunga ne-26%.
3. Yandisa imveliso
Kwinqanaba lokuhluma okanye ukuhluma kweengcambu, isiqu kunye nemifuno enamagqabi, ukutshiza i-50 kilograms ye-200 ~ 300ppm isisombululo se-paclobutrazol nge-acre kunokukhuthaza ukujiya kwamagqabi emifuno, ukunciphisa i-internodes, izityalo ezomeleleyo, umgangatho ophuculweyo, kunye nokwanda kwesivuno. Umzekelo, ngaphambi kokukha iikhukhamba, zitshize nge-400 mg / L yesisombululo se-paclobutrazol ukwandisa isivuno malunga ne-20% ukuya kwi-25%.
Kwinqanaba le-4 lamagqabi ekwindla kwi-greenhouses, fafaza i-100 mg/L ye-paclobutrazol engamanzi ukwenza mfutshane i-internodes, udibanise ukumila kwesityalo, kwaye ujiye izikhondo. Ukumelana ne powdery mildew kunye ne-downy mildew kuyaphuculwa, ukuxhathisa kwengqele kuyaphucuka, kwaye izinga lokumisela iziqhamo liyenyuka. , izinga lokunyuka kwesivuno lifikelela malunga ne-20%.
Kwinqanaba le-3-4 leqabunga lekhaphetshu yaseTshayina, ukutshiza izityalo nge-50-100 mg/L yesisombululo se-paclobutrazol kungenza izityalo zibe zincinci kwaye zandise inani lembewu malunga ne-10% -20%.
Xa i-radish inamaqabunga angama-3 ukuya kuma-4 okwenyaniso, yitshiza nge-45 mg / L isisombululo se-paclobutrazol ukunyusa ukuchasana nokunciphisa iziganeko; ngexesha lokubunjwa kweengcambu ezinomzimba, zitshize nge-100 mg / L paclobutrazol isisombululo sokuthintela ukukhula kwezityalo. Ithintela i-bolting, yenza isityalo sishiya amaqabunga aluhlaza, yenza amagqabi abe mafutshane kwaye athe tye, iphucula i-photosynthesis, kwaye ikhuthaza ukuthuthwa kweemveliso ze-photosynthetic kwiingcambu ezinomzimba, ezinokunyusa isivuno nge-10% ukuya kwi-20%, ukukhusela i-bran cores, kunye nokuphucula ukuthengiswa. .
Ukutshiza i-edamame nge-100 ukuya kwi-200 mg/L ye-paclobutrazol engamanzi ngexesha lokuqala ukuya kwinqanaba elipheleleyo leentyatyambo kunokunyusa amasebe asebenzayo, inani le-pod elisebenzayo kunye nobunzima be-pod, kunye nokwandisa isivuno malunga ne-20%. Xa iidiliya zikhwela phezulu kwishelufu, fafaza i-yam nge-200 mg / L paclobutrazol liquid. Ukuba ukukhula kunamandla kakhulu, yitshize kanye ngeentsuku ezi-5 ukuya kwezi-7, kwaye utshize ka-2 ukuya ku-3 ngokuqhubekayo ukuthintela ukukhula kweziqu kunye namagqabi kwaye ukhuthaze ukuntshula kwamasebe asecaleni. Iintyatyambo zikhula, i-tubers ikhula, kwaye isivuno sonyuka malunga ne-10%.
4. Yazisa iziphumo zakwangoko
Isichumiso se-nitrogen esininzi sisetyenziswa kwintsimi yemifuno, okanye imifuno ifakwe umthunzi kwaye ukukhanya akwanelanga, okanye ukufuma kwemifuno kwindawo ekhuselweyo kuphezulu ebusuku, njl. zinde, zichaphazela ukukhula kwenzala kunye nokumila kweziqhamo. Ungatshiza i-50 kg ye-200ppm engamanzi ngehektare nganye ukunqanda Izikhondo kunye namagqabi anemilenze, ekhuthaza ukukhula kokuzala kunye nokuqhama kwangethuba. Ngethuba lokubunjwa kweengcambu ezinomzimba, ukutshiza i-100-150 mg / L isisombululo se-paclobutrazol emagqabini, iilitha ezingama-30-40 ngehektare nganye, inokulawula ukukhula kwamacandelo angasentla kunye nokukhuthaza i-hypertrophy yeengcambu ezinomzimba. Nika ingqalelo kugxininiso oluchanekileyo lweyeza kunye nokutshiza okufanayo. Khuthaza ukuvuthwa kweziqhamo. Emva kweziqhamo, fafaza nge 500 mg/L isisombululo se paclobutrazol ukuthintela ukukhula kwezityalo nokukhuthaza ukukhula kweziqhamo.
Ukulumkela
Lawula ngokungqongqo ubungakanani kunye nexesha lamayeza. Ukuba isityalo sonke sitshizwe, ukwenzela ukwandisa ukunamathela kwi-liquid, yongeza inani elifanelekileyo le-powder yokuhlamba engathathi hlangothi kwi-liquid. Ukuba i-dosage inkulu kakhulu kwaye i-concentration iphezulu kakhulu, kubangela ukuba ukukhula kwezityalo kuthintelwe, unokwandisa ukusetyenziswa kwezichumisi ezikhawulezayo, okanye usebenzise i-gibberellin (92O) ukunciphisa ingxaki. Sebenzisa i-0.5 ukuya kwi-1 grams ngehektare nganye kwaye utshize i-30 ukuya kwi-40 yeekhilogram zamanzi.
