He maha ngā mahi a te waikawa salicylic i roto i te ahuwhenua, tae atu ki te noho hei kaiwhakahaere tipu, hei patu pepeke, me hei paturopi.
Waikawa salicylic, heikaiwhakahaere tipu tipu,He mahi nui tā te waikawa salicylic ki te whakatairanga i te tipu o ngā tipu me te whakapiki i ngā hua o ngā hua. Ka taea e ia te whakarei ake i te hanganga o ngā homoni i roto i ngā tipu, te whakateretere i tō rātou tipu me te rerekētanga, me te āwhina hoki i ngā tipu ki te urutau ki ngā huringa taiao. Ka taea hoki e te waikawa salicylic te aukati i te roa o ngā pito o ngā tipu, te whakapakari i ngā tipu me te whakaiti i te putanga mai o ngā mate me ngā pepeke. Haunga te mea he kaiwhakahaere tipu tipu, ka taea hoki te whakamahi i te waikawa salicylic hei patu pepeke. I roto i te mara ahuwhenua, ko ngā tauira noa ko te waikawa acetylsalicylic me te konutai salicylate. Ka taea e ēnei matū te patu pai i ngā pepeke me ngā mate e pirinoa ana ki ngā tipu, hei tiaki i te tipu o ngā hua. I roto i te mara hauora, he rongoā ārai-mate noa hoki te waikawa salicylic. I roto i te mara ahuwhenua, ka whakamahia te waikawa salicylic hei ārai i ngā mate pāwera i roto i ngā kararehe. I taua wā anō, ka taea e te waikawa salicylic te whakarei ake i te ātete ki te mate me te wā rokiroki o ngā hua ahuwhenua.
Ehara te Waikawa Salicylic (he whakarāpopototanga ko SA) i te patu pepeke tuku iho (pērā i te patu pepeke, te patu harore, te patu otaota rānei) i roto i te ahuwhenua. Heoi, he tino nui tana mahi i roto i te tikanga tiaki tipu me te whakahaere i te ātete ki te ahotea. I ngā tau tata nei, kua whānuitia te rangahau i te waikawa salicylic, ā, kua whakamahia hoki i roto i te ahuwhenua hei whakaoho ārai mate tipu, hei whakaoho koiora rānei, ā, ko āna mahi matua e whai ake nei:
1. Te whakahohenga o te ātete ā-pūnaha tipu (SAR)
Ko te waikawa salicylic he ngota tohu e puta noa ana i roto i ngā tipu, ka tere te kohikohi i muri i te pangia e ngā pathogens.
Ka taea e ia te whakahohe i te ātete ā-pūnaha (SAR), ka puta ai te ātete whānui o te tipu katoa ki ngā momo mate pāwera (ina koa ko te harore, te huakita me ngā huaketo).
2. Whakapai ake i te manawanui o ngā tipu ki ngā ahotea kore-koiora
Ka taea e te waikawa salicylic te whakarei ake i te ātete o ngā tipu ki ngā ahotea kore-koiora pērā i te tauraki, te tote, te pāmahana iti, te pāmahana tiketike, me te parahanga konganuku taumaha.
Ko ngā tikanga ko: te whakahaere i te mahi a ngā whākōkī ārai-mate (pēnei i te SOD, POD, CAT), te pupuri i te pumau o ngā kiriuhi pūtau, me te whakatairanga i te kohikohinga o ngā matū whakahaere osmotic (pēnei i te proline, ngā huka wairewa), me ētahi atu.
3. Te whakahaere i te tipu me te whanaketanga o ngā tipu
Ka taea e te iti o te kukū o te waikawa salicylic te whakatairanga i te whakatipu purapura, te whanaketanga pakiaka me te photosynthesis.
Heoi anō, mā te nui o ngā kukū ka ārai i te tipu, e whakaatu ana i te "pānga homoni rua-wāhanga" (pānga hormesis).
4. Hei wāhanga o te rautaki whakahaere matomato
Ahakoa kāore e taea e te waikawa salicylic te patu tika i ngā huakita mate, ka taea e ia te whakaiti i te whakamahinga o ngā patupatu matū mā te whakaoho i te pūnaha parepare a te tipu.
He maha ngā wā ka whakamahia ngātahitia me ētahi atu matū koiora (pēnei i te chitosan, te waikawa jasmonic) hei whakarei ake i tōna whai huatanga.
Ngā puka tono tuturu
Te rehu rau: Ko te kukū noa ko te 0.1–1.0 mM (tata ki te 14–140 mg/L), ka taea te whakarerekē i runga i te momo hua me te kaupapa.
Te maimoatanga purapura: Te ruirui i ngā purapura hei whakapakari i te ātete ki ngā mate me te tere o te whakatipu.
Te whakaranu ki ngā patupatu: Te whakapakari i te ātete whānui o ngā hua ki ngā mate me te whakaroa i te whai huatanga o te patupatu.
Ngā Tuhipoka hei Whakarongo
Ka pāngia pea ngā tipu e te paitini ki te nui rawa o te kukū (pērā i te wera o te rau me te aukati i te tipu).
He nui te pānga o ngā āhuatanga o te taiao (te pāmahana, te haumākū), ngā momo hua me te wā tono.
I tēnei wā, kāore anō kia rēhitatia mana te waikawa salicylic hei patu pepeke i Haina me te nuinga o ngā whenua kē atu. He nui ake te whakamahinga hei kaiwhakahaere tipu tipu, hei whakaohooho koiora rānei.
Whakarāpopototanga
Ko te uara matua o te waikawa salicylic i roto i te ahuwhenua kei roto i te "tiaki i ngā tipu mā roto i ngā tipu" - mā te whakahohe i ngā pūnaha ārai mate o ngā tipu hei ātete i ngā mate me ngā āhuatanga kino. He matū mahi e rite ana ki ngā ariā o te ahuwhenua matomato me te whanaketanga tauwhiro. Ahakoa ehara i te patu pepeke tuku iho, he nui tōna kaha ki te whakahaere pepeke whakauru (IPM).
