Ntchito zazikulu za 4-Chlorophenoxyacetic acid (4-CPA)
4-Chlorophenoxyacetic acid (4-CPA) ndi phenolic chomera chowongolera kukula. 4-Chlorophenoxyacetic acid (4-CPA) imatha kuyamwa ndi mizu, zimayambira, masamba, maluwa, ndi zipatso za zomera. Ntchito yake yachilengedwe imakhala nthawi yayitali. Zotsatira zake za thupi ndizofanana ndi mahomoni amkati, kulimbikitsa kugawanika kwa maselo ndi kusiyana kwa minofu, kumalimbikitsa kukula kwa ovary, kuchititsa parthenocarpy, kupanga zipatso zopanda mbewu, ndi kulimbikitsa kukhazikitsidwa kwa zipatso ndi kukula kwa zipatso.
[Gwiritsani ntchito patsamba 1]Imagwiritsidwa ntchito ngati chowongolera kukula kwa mbewu, choletsa kugwa kwa zipatso, herbicide, itha kugwiritsidwa ntchito pakupeputsa maluwa a phwetekere ndi kupatulira zipatso za pichesi.
[Gwiritsani ntchito patsamba 2]Hormone yakukula kwa mbewu, yomwe imagwiritsidwa ntchito ngati chowongolera kukula, choletsa kugwa kwa zipatso, herbicide, imatha kugwiritsidwa ntchito ngati tomato, masamba, mitengo ya pichesi, ndi zina zambiri, komanso kugwiritsidwa ntchito ngati mankhwala apakatikati. 4-Chlorophenoxyacetic acid (4-CPA) main application 4-Chlorophenoxyacetic acid (4-CPA) imagwiritsidwa ntchito makamaka kupewa kugwa kwa maluwa ndi zipatso, kuletsa mizu ya nyemba, kulimbikitsa kukhazikika kwa zipatso, kuyambitsa zipatso zopanda mbewu, komanso kupsa ndi kukula. . 4-Chlorophenoxyacetic acid (4-CPA imatha kuyamwa ndi mizu, zimayambira, maluwa ndi zipatso, ndipo zochitika zake zamoyo zimatha kwa nthawi yayitali. Kugwiritsidwa ntchito kwake ndi 5-25ppm, ndi kufufuza zinthu kapena 0.1% potaziyamu dihydrogen phosphate akhoza kuwonjezeredwa. moyenerera Imakhala ndi zotsatira zabwino zolepheretsa nkhungu yotuwa, ndipo kugwiritsa ntchito pafupipafupi ndi 50-80ppm.
1. Kuchulukitsa zokolola koyambirira komanso kukhwima koyambirira.
Zimagwira ntchito pa mbewu zokhala ndi mazira ambiri, monga tomato, biringanya, nkhuyu, mavwende, zukini, ndi zina zotero. Sanizani biringanya ndi 25-30 mg/L 4-Chlorophenoxyacetic acid (4-CPA yankho panthawi ya maluwa, kawiri motsatizana; ndi nthawi ya sabata imodzi nthawi iliyonse pamene tomato ali pakati pa kuphuka, perekani ndi 25-30 mg/L 4-Chlorophenoxyacetic acid (4-CPA solution kamodzi) Tsabola amapopera 15-25 mg/L 4-Chlorophenoxyacetic acid (4-CPA yankho kamodzi pa nthawi ya maluwa.
2. 4-Chlorophenoxyacetic acid (4-CPA imagwiritsidwa ntchito mu fodya kuchepetsa chikonga.
3. 4-Chlorophenoxyacetic acid (4-CPA imagwiritsidwa ntchito mumaluwa okongoletsera kuti maluwa akule mwamphamvu, kuonjezera maluwa ndi zipatso zatsopano, ndikuwonjezera nthawi yamaluwa.
4. 4-Chlorophenoxyacetic Acid (4-CPA imagwiritsidwa ntchito ngati tirigu, chimanga, mpunga, nyemba ndi mbewu zina zambewu. Imatha kupewa zipolopolo zopanda kanthu. Itha kupeza mbewu zonse, kuchuluka kwa zipatso, kuchuluka kwa zokolola, zokolola zambiri komanso msanga. kukhwima.
5. Wonjezerani zokolola za masamba ndi zipatso zosiyanasiyana. Mwachitsanzo, kuchuluka kwa zipatso za tomato kumakhala bwino. Zokolola zoyamba zimachulukitsidwa ndipo nthawi yokolola imayamba msanga. Chivwende chimapopedwa, zokolola zimachuluka, mtundu wake ndi wabwino, zipatso zake ndi zazikulu, shuga ndi vitamini C zimakhala zambiri, ndipo mbewu zimakhala zochepa. Munthawi yamaluwa ya chivwende, 20 mg/L ya anti-drop solution imapopera nthawi 1 mpaka 2, ndipo nthawi ziwiri ziyenera kupatulidwa. Kabichi waku China, 25-35 mg/L wa 4-Chlorophenoxyacetic acid (4-CPA solution amapopera masana padzuwa pasanathe masiku 3-15 kukolola, zomwe zingalepheretse kugwa kwa kabichi panthawi yosungiramo ndikusunga. mwatsopano-kusunga zotsatira.
6. 4-Chlorophenoxyacetic acid (4-CPA imagwiritsidwa ntchito kulima nyemba zopanda mizu).
Kusamala pogwiritsa ntchito 4-CPA
(1) Siyani kugwiritsa ntchito masiku atatu musanakolole masamba.
Wothandizira uyu ndi wotetezeka kuposa 2,4-D. Ndikoyenera kugwiritsa ntchito chopopera pang'ono popopera maluwa (monga mankhwala opopera pakhosi) ndikupewa kupopera mbewu panthambi zanthete ndi masamba atsopano. Yang'anirani kwambiri mlingo, ndende ndi nthawi yogwiritsira ntchito kuti mupewe kuwonongeka kwa mankhwala.
(2) Pewani kugwiritsa ntchito masiku otentha ndi adzuwa kapena mvula kuti muteteze kuwonongeka kwa mankhwala.
Mankhwalawa sangagwiritsidwe ntchito pamasamba ngati mbewu.
