Usetyenziso oluphambili lwe-4-Chlorophenoxyacetic acid (4-CPA)
I-4-Chlorophenoxyacetic acid (4-CPA) yi-phenolic plant growth regulator. I-4-Chlorophenoxyacetic acid (4-CPA) inokufunxwa ziingcambu, iziqu, amagqabi, iintyatyambo kunye neziqhamo zezityalo. Umsebenzi wayo webhayoloji uhlala ixesha elide. Iziphumo zayo ze-physiological zifana neehomoni ezingapheliyo, ezikhuthaza ukwahlukana kweeseli kunye nokwahlukana kwezicubu, ukuvuselela ukwanda kwe-ovary, ukukhuthaza i-parthenocarpy, ukwenza iziqhamo ezingenambewu, kunye nokukhuthaza ukusekwa kweziqhamo kunye nokwandiswa kweziqhamo.
[Sebenzisa 1]Isetyenziswa njengokulawula ukukhula kwezityalo, isithinteli sokuwisa iziqhamo, imichiza yokutshabalalisa ukhula, ingasetyenziselwa ukucutha iintyatyambo zetumata kunye nokucutha iziqhamo zepesika.
[Sebenzisa 2]Ihomoni yokukhula kwezityalo, esetyenziswa njengokulawula ukukhula, isithinteli sokulahla iziqhamo, i-herbicide, ingasetyenziselwa iitumato, imifuno, imithi yeepesika, njl. I-4-Chlorophenoxyacetic acid (4-CPA) isicelo esiphambili 4-Chlorophenoxyacetic acid (4-CPA) isetyenziswa ikakhulu ukuthintela ukuwisa kwentyatyambo kunye neziqhamo, inqanda iingcambu zeembotyi, ikhuthaza ukumiselwa kweziqhamo, ibangele isiqhamo esingenambewu, kwaye ibe nefuthe lokuvuthwa nokukhula. . I-4-Chlorophenoxyacetic acid (i-4-CPA inokufunxwa ngeengcambu, iziqu, iintyatyambo kunye neziqhamo, kwaye umsebenzi wayo webhayoloji uhlala ixesha elide. Ugxininiso lokusetyenziswa luyi-5-25ppm, kunye ne-trace elements okanye i-0.1% ye-potassium dihydrogen phosphate inokongezwa. ngokufanelekileyo Unefuthe elihle lokuthintela kwi-gray mold, kunye nokugxilwa kokusetyenziswa ngokubanzi yi-50-80ppm.
1. Ukunyuka kwesivuno kwangethuba kunye nokuvuthwa kwangoko.
Isebenza kwizityalo ezinama-ovules amaninzi, afana neetumato, ii-eggplants, amakhiwane, ivatala, i-zucchini, njl. kunye nesithuba seveki e-1 ngexesha ngalinye Xa iitumato zikwisiqingatha sokudumba, zitshize nge-25-30 mg/L 4-Chlorophenoxyacetic acid (4-CPA isisombululo kanye. I-4-Chlorophenoxyacetic acid (4-CPA isisombululo kanye ngexesha leentyantyambo.
2. I-4-Chlorophenoxyacetic acid (i-4-CPA isetyenziselwa icuba ukunciphisa umxholo we-nicotine.
3. I-4-Chlorophenoxyacetic acid (i-4-CPA isetyenziselwa iintyatyambo zokuhlobisa ukwenza iintyatyambo zikhule ngamandla, ukwandisa iintyatyambo ezintsha kunye neziqhamo, kunye nokwandisa ixesha leentyantyambo.
4. I-4-Chlorophenoxyacetic acid Acid (4-CPA isetyenziselwa ingqolowa, umbona, irayisi, iimbotyi kunye nezinye izityalo eziziinkozo. Iyakwazi ukuthintela amaqokobhe angenanto. Inokufikelela kwiinkozo ezigcweleyo, ukunyuka kwezinga lokumisela iziqhamo, ukwanda kwesivuno, isivuno esikhulu kunye nokuqala. ukukhula.
5. Yandisa isivuno semifuno neziqhamo ezahlukeneyo. Umzekelo, izinga lokumisela iziqhamo kwiitumato liyaphuculwa. Isivuno sakwangoko siyanyuswa kwaye ixesha lokuvuna lisekuqaleni. I-Watermelon iyatshizwa, isivuno sandiswa, umbala ulungile, isiqhamo sikhulu, ishukela kunye ne-vitamin C umxholo ophezulu, kwaye imbewu incinci. Ngethuba lexesha leentyantyambo ze-watermelon, i-20 mg / L yesisombululo esichasene ne-drop ifafazwe ngamaxesha angama-1 ukuya kuma-2, kwaye amaxesha ama-2 kufuneka ahlulwe. Kwikhaphetshu yaseTshayina, i-25-35 mg/L ye-4-Chlorophenoxyacetic acid (isisombululo se-4-CPA sitshizwa emva kwemini ngemini enelanga 3-15 iintsuku phambi kokuvuna, nto leyo enokuthintela ukuba ikhaphetshu liwe ngexesha lokugcina isiphumo sokugcina ngokutsha.
6. I-4-Chlorophenoxyacetic acid (i-4-CPA isetyenziselwa ukulima iimbotyi ezingenangcambu.
Izilumkiso zokusebenzisa i-4-CPA
(1) Yeka ukuyisebenzisa kwiintsuku ezi-3 phambi kokuvuna imifuno.
Le arhente ikhuselekile kuno-2,4-D. Kucetyiswa ukuba usebenzise isitshizi esincinci sokutshiza iintyatyambo (ezifana nesitshizi somqala wezonyango) kwaye ugweme ukutshiza kumasebe ethenda kunye namahlumelo amatsha. Lawula ngokungqongqo idosi, ukugxininiswa kunye nexesha lesicelo ukuthintela umonakalo weziyobisi.
(2) Kuphephe ukufaka isicelo ngeentsuku ezishushu nezinelanga okanye ezinemvula ukuthintela ukonakala kweziyobisi.
