4-chlorophenoxyacetic acid njira ndi njira zodzitetezera kuti zigwiritsidwe ntchito pa mavwende, zipatso ndi masamba

Ndi mtundu wa kukula kwa hormone, yomwe imatha kulimbikitsa kukula, kuteteza mapangidwe olekanitsa, komanso kulimbikitsa chikhalidwe chake cha zipatso ndi mtundu wa zowongolera kukula kwa zomera. Ikhoza kuyambitsa parthenocarpy. Pambuyo pakugwiritsa ntchito, ndiyotetezeka kuposa 2, 4-D ndipo sizovuta kuwononga mankhwala. Ikhoza kuyamwa ndi mizu, maluwa ndi zipatso, ndipo ntchito yake yachilengedwe imakhala kwa nthawi yayitali. Mphesa ya Jufeng imakhudzidwa kwambiri ndi iyo, osati yoyenera kupopera mbewu mankhwalawa.

Kukhazikika kwa4-chlorophenoxyacetic asidi sodium: 5-25ppm ndiyoyenera, ndipo kuchuluka koyenera kwa zinthu kapena 0.1% potaziyamu dihydrogen phosphate kuli bwino

Njira yogwiritsira ntchito: yomwe imadziwika kuti mzimu wokolola, udindo wake ndi kuonjezera chiwerengero cha zipatso, kufulumizitsa kukula kwa zipatso zazing'ono, zomwe zimagwiritsidwa ntchito mu tomato, biringanya, tsabola, nkhaka, mavwende ndi zipatso zina ndi ndiwo zamasamba.

(1) Mu maluwa nthawi ya biringanya ndi ndende ya 25-30 mg/l wa odana kugwa madzi kutsitsi, kawiri zotsatizana, aliyense imeneyi 1 sabata.

(2) Kwa tomato mu theka la duwa, ndi 25-30 mg/l ya anti-kugwa kutsitsi kamodzi. Tsabola utsi kamodzi ndi 15-25 mg/l wa4-chlorophenoxyacetic asidi sodiummu njira pa nthawi ya maluwa.

(3) chivwende mu nthawi ya maluwa ndi 20 mg/l ya odana ndi kugwa timadzi madzi utsi 1 mpaka 2, ndi imeneyi wapakatikati.

(4) Kwa kabichi waku China, masiku 3-15 isanafike kukolola ndi 25-35 mg/l ya China kabichi odana ndi kugwa madzi kutsitsi masana pa tsiku la dzuwa, akhoza bwino kuteteza Chinese kabichi kugwa pa yosungirako, ndipo ali ndi zotsatira za kusunga.

Mukamapopera mankhwala odana ndi kugwa, tcherani khutu ku: choyamba, maluwa opopera ayenera kukhazikitsidwa (maluwa okhawo atsitsi ndipo sangathe kupopera zimayambira, masamba), tikulimbikitsidwa kugwiritsa ntchito botolo la kutsitsi la banja ndi maluwa opopera amadzimadzi, nthawi yopopera iyenera kusankhidwa m'mawa kapena madzulo, ngati kutentha kwambiri, dzuwa lotentha kapena kutsitsi kwa tsiku lamvula ndilosavuta kutulutsa mankhwala osokoneza bongo. Chachiwiri, mukamagwiritsa ntchito choyera cha4-chlorophenoxyacetic asidi sodium, m'pofunikanso kusungunula ndi mowa kapena high-concentration soju poyamba, ndiyeno kuwonjezera madzi ku ndende yofunikira.
