Zinthu zanyengo zogwirira ntchito kwa Ethephon

Kutulutsidwa kwa ethylene kuchokeraethephonyankho silimangogwirizana kwambiri ndi pH mtengo, komanso limagwirizana ndi zochitika zakunja zachilengedwe monga kutentha, kuwala, chinyezi, ndi zina zotero, choncho onetsetsani kuti mukuyang'anitsitsa vutoli mukugwiritsa ntchito.

(1) Vuto la kutentha

Kuwonongeka kwaethephonkumawonjezeka ndi kuwonjezeka kutentha.Malinga ndi mayeso, pansi pa zinthu zamchere, ethephon imatha kuwonongeka kwathunthu ndikumasulidwa m'madzi otentha kwa mphindi 40, ndikusiya ma chloride ndi phosphates.Zatsimikiziridwa ndi machitidwe kuti zotsatira za ethephon pa mbewu zimagwirizana ndi kutentha kwa nthawi imeneyo.Kawirikawiri, m'pofunika kusunga kutentha koyenera kwa nthawi inayake mutatha chithandizo kuti mukhale ndi zotsatira zoonekeratu, ndipo mkati mwamtundu wina wa kutentha, zotsatira zake zimawonjezeka ndi kuwonjezeka kwa kutentha.

Mwachitsanzo,ethephonimakhala ndi zotsatira zabwino pakucha kwa thonje pa kutentha kwa 25 ° C;20 ~ 25 °C imakhalanso ndi zotsatira zina;M'munsimu 20 ° C, zotsatira za kucha ndizochepa kwambiri.Izi ndichifukwa choti ethylene imafunikira kutentha koyenera panthawi yochita nawo ntchito zakuthupi ndi zamankhwala.Panthawi imodzimodziyo, mkati mwa kutentha kwina, kuchuluka kwa ethephon kulowa mu chomera kumawonjezeka ndi kuwonjezeka kwa kutentha.Kuphatikiza apo, kutentha kwapamwamba kumatha kufulumizitsa kuyenda kwa ethephon muzomera.Chifukwa chake, kutentha kwabwino kumatha kusintha magwiridwe antchito a ethephon.

(2) Mavuto ounikira

Kuwala kwinakwake kumatha kulimbikitsa kuyamwa ndi kugwiritsidwa ntchito kwaethephonndi zomera.Pansi pa kuwala, photosynthesis ndi kutuluka kwa zomera kumalimbikitsidwa, zomwe zimathandiza kuti ethephon ikhale ndi kayendedwe ka zinthu zamoyo, ndipo stomata ya masamba imatseguka kuti ilowetse ethephon m'masamba.Choncho, zomera ziyenera kugwiritsa ntchito ethephon masiku adzuwa.Komabe, ngati kuwala kuli kolimba kwambiri, madzi a ethephon omwe amapopera pamasamba ndi osavuta kuuma, zomwe zidzakhudza kuyamwa kwa ethephon ndi masamba.Choncho, m'pofunika kupewa kupopera mbewu mankhwalawa pansi pa kuwala kotentha ndi kolimba masana m'chilimwe.

(3) Chinyezi cha mpweya, mphepo ndi mvula

The mpweya chinyezi kudzakhudzanso mayamwidweethephonndi zomera.Kuchuluka kwa chinyezi sikophweka kuti madziwo aume, omwe ndi abwino kuti ethephon alowe mu chomera.Ngati chinyezi chili chochepa kwambiri, madziwo amauma mofulumira pamasamba, zomwe zidzakhudza kuchuluka kwa ethephon kulowa mu chomera..Ndi bwino kupopera ethephon ndi kamphepo.Mphepo imakhala yamphamvu, madziwo amamwazika ndi mphepo, ndipo kugwiritsa ntchito bwino kumakhala kochepa.Choncho, m'pofunika kusankha tsiku ladzuwa ndi mphepo yaing'ono.

Sipayenera kukhala mvula mkati mwa maola 6 mutatha kupopera mbewu mankhwalawa, kuti ethephon isakokoloke ndi mvula ndi kusokoneza mphamvu yake.
