Zinthu za nyengo zomwe zimapangitsa kuti Ethephon igwire bwino ntchito

Kutulutsidwa kwa ethylene kuchokera kuethefoniYankho silimangogwirizana ndi pH yokha, komanso limagwirizana ndi zinthu zakunja monga kutentha, kuwala, chinyezi, ndi zina zotero, choncho onetsetsani kuti mwasamala za vutoli lomwe likugwiritsidwa ntchito.

(1) Vuto la kutentha

Kuwonongeka kwaethefoniKuchuluka kwa kutentha kumawonjezeka. Malinga ndi mayesowa, pansi pa mikhalidwe ya alkaline, ethephon imatha kusungunuka kwathunthu ndikutulutsidwa m'madzi otentha kwa mphindi 40, ndikusiya ma chloride ndi ma phosphates. Zatsimikiziridwa ndi machitidwe kuti zotsatira za ethephon pa mbewu zimagwirizana ndi kutentha panthawiyo. Nthawi zambiri, ndikofunikira kusunga kutentha koyenera kwa nthawi inayake mutalandira chithandizo kuti mukhale ndi zotsatira zoonekeratu, ndipo mkati mwa kutentha kwina, zotsatira zake zimawonjezeka ndi kuwonjezeka kwa kutentha.

Mwachitsanzo,ethefoniZimathandiza kwambiri pakukhwima kwa thonje pa kutentha kwa 25 °C; 20~25 °C imakhudzanso; pansi pa 20 °C, mphamvu ya kucha imakhala yotsika kwambiri. Izi zili choncho chifukwa ethylene imafuna kutentha koyenera pochita nawo zochitika za thupi ndi za biochemical za zomera. Nthawi yomweyo, mkati mwa kutentha kwina, kuchuluka kwa ethephon komwe kumalowa mu chomera kumawonjezeka ndi kutentha kwakukulu. Kuphatikiza apo, kutentha kwakukulu kumatha kufulumizitsa kuyenda kwa ethephon mu chomera. Chifukwa chake, kutentha koyenera kumatha kusintha mphamvu ya ethephon.

(2) Mavuto a magetsi

Kuwala kwina kungathandize kuyamwa ndi kugwiritsa ntchitoethefonindi zomera. Pakakhala kuwala, photosynthesis ndi kutuluka kwa zomera zimalimbikitsidwa, zomwe zimathandiza kuti ethephon iyende bwino ndi zinthu zachilengedwe, ndipo stomata ya masamba imatseguka kuti ethephon ilowe m'masamba mosavuta. Chifukwa chake, zomera ziyenera kugwiritsa ntchito ethephon masiku a dzuwa. Komabe, ngati kuwala kuli kolimba kwambiri, madzi a ethephon omwe amathiridwa pamasamba ndi osavuta kuumitsa, zomwe zimakhudza kuyamwa kwa ethephon ndi masamba. Chifukwa chake, ndikofunikira kupewa kupopera pansi pa kuwala kotentha komanso kwamphamvu masana m'chilimwe.

(3) Chinyezi cha mpweya, mphepo ndi mvula

Chinyezi cha mpweya chidzakhudzanso kuyamwa kwaethefonindi zomera. Chinyezi chochuluka sichimavuta kuti madziwo aume, zomwe zimathandiza kuti ethephon ilowe mu chomera. Ngati chinyezi chili chochepa kwambiri, madziwo amauma mwachangu pamwamba pa tsamba, zomwe zingakhudze kuchuluka kwa ethephon yomwe imalowa mu chomera. . Ndi bwino kupopera ethephon ndi mphepo. Mphepo ndi yamphamvu, madziwo adzafalikira ndi mphepo, ndipo kugwiritsa ntchito bwino kwake ndi kochepa. Chifukwa chake, ndikofunikira kusankha tsiku lowala ndi mphepo yochepa.

Mvula isagwe mkati mwa maola 6 mutathira, kuti mvula isawononge mphamvu ya ethephon.
