Njira 4 zopewera kugwiritsa ntchito sodium chlorophenoxyacetic acid pa mavwende, zipatso ndi ndiwo zamasamba

Ndi mtundu wa hormone yokulira, yomwe ingathandize kukula, kupewa kupangika kwa gawo lolekanitsidwa, ndikulimbikitsa kukhazikika kwa zipatso zake, komanso ndi mtundu wa wowongolera kukula kwa zomera. Ikhoza kuyambitsa parthenocarpy. Pambuyo poigwiritsa ntchito, imakhala yotetezeka kuposa 2, 4-D ndipo siiwononga mankhwala mosavuta. Imatha kuyamwa ndi mizu, maluwa ndi zipatso, ndipo ntchito yake yachilengedwe imatenga nthawi yayitali. Mphesa ya Jufeng imakhala yolimba kwambiri, siyoyenera kupopera masamba.

Kuchuluka kwa4-chlorophenoxyacetic acid sodium: 5-25ppm ndi yoyenera, ndipo kuchuluka koyenera kwa zinthu zochepa kapena 0.1% potassium dihydrogen phosphate ndikwabwino

Njira yogwiritsira ntchito: yomwe imadziwika kuti spirit yokolola, ntchito yake ndikuwonjezera kuchuluka kwa zipatso, kufulumizitsa kukula kwa zipatso zazing'ono, zomwe nthawi zambiri zimagwiritsidwa ntchito mu tomato, biringanya, tsabola, nkhaka, chivwende ndi zipatso ndi ndiwo zamasamba zina.

(1) Mu nthawi ya maluwa a biringanya ndi kuchuluka kwa 25-30 mg/l ya mankhwala oletsa kugwa, kawiri motsatizana, nthawi iliyonse ya sabata imodzi.

(2) Pa tomato m'kati mwa duwa, perekani 25-30 mg/l ya mankhwala oletsa kugwa kamodzi. Perekani tsabola kamodzi ndi 15-25 mg/l ya4-chlorophenoxyacetic acid sodiummu yankho panthawi ya maluwa.

(3) chivwende chikayamba kuphuka ndi 20 mg/l ya mankhwala ophera tizilombo toyambitsa matenda nthawi imodzi kapena ziwiri, nthawi yapakati.

(4) Pa kabichi waku China, masiku 3-15 musanakolole ndi 25-35 mg/l ya kabichi waku China wothira madzi oletsa kugwa masana tsiku lowala, zitha kuteteza kabichi waku China kuti asagwe panthawi yosungidwa, ndipo zimathandiza kuti asungidwe.

Mukapopera zinthu zotsutsana ndi kugwa, samalani izi: choyamba, maluwa opopera ayenera kukhazikika (popera maluwa okha ndipo simungathe kupopera tsinde, masamba), ndi bwino kugwiritsa ntchito botolo lopopera lapakhomo ndi maluwa opopera madzi, nthawi yopopera iyenera kusankhidwa m'mawa kapena madzulo, ngati kutentha kwambiri, dzuwa lotentha kapena mvula sikungathe kuwononga mankhwala. Chachiwiri, mukamagwiritsa ntchito mankhwala oyera a4-chlorophenoxyacetic acid sodium, ndikofunikiranso kusungunula ndi mowa kapena soju yokhala ndi kuchuluka kwakukulu kaye, kenako onjezerani madzi ku kuchuluka kofunikira.
