Mu gutera inyanya, izi ngamba enye zigenzura imikurire y'ibimera zishobora guteza imbere ishyirwaho ry'imbuto z'inyanya no gukumira kutagira imbuto

Mu gihe cyo gutera inyanya, dukunze guhura n’ikibazo cyo kutagira imbuto nyinshi no kutagira umusaruro mwinshi, muri iki gihe, ntabwo tugomba kubihangayikishwa, kandi dushobora gukoresha uburyo bukwiye bwo kugenzura imikurire y’ibimera kugira ngo dukemure uru ruhererekane rw’ibibazo.

1. Ethephon

Kimwe ni ukugabanya ubusembwa. Bitewe n'ubushyuhe bwinshi, ubushuhe bwinshi no gutinda gutera cyangwa gutera mu gihe cy'ihinga ry'imbuto, gukura kw'imbuto bishobora kugenzurwa hakoreshejwe 300mg/kg y'amababi ya ethylene spray iyo amababi 3, hagati 1 n'amababi 5 nyayo, kugira ngo imbuto zikomere, amababi abe manini, amashami abe akomeye, imizi ikure, ubushobozi bwo guhangana n'imihangayiko bwiyongere, kandi umusaruro wiyongera hakiri kare. Ingano ntigomba kuba iri hejuru cyane cyangwa hasi cyane.

Icya kabiri ni icyo guhisha, hari uburyo butatu:
(1) Ifu yo gusiga ku mashaza: Iyo imbuto zera kandi zeze, 300mg/kg ya ethephon ishyirwa ku ibara ry'ururabo rw'igice cya kabiri cy'amashaza, kandi ishobora kuba itukura kandi yeze iminsi 3 ~ 5.
(2) Ifu y'imbuto: 400mg/kg ya ethephon ishyirwa ku mfuruka n'ubuso bw'imbuto zera zeze hafi y'indabyo z'imbuto zera, kandi itukura yeze mbere y'iminsi 6-8.
(3) Gukuraho imbuto: Imbuto zo mu gihe cyo guhindura ibara zirakusanywa zikanigwa mu gipimo cya 2000-3000mg /kg cya ethylene mu gihe cya selile 10 kugeza 30, hanyuma zikavanwamo zigashyirwa kuri 25 ° C kandi ubushyuhe bw'ikirere bugera kuri 80% kugeza 85% kugira ngo zeze, kandi zishobora guhinduka umutuku nyuma y'iminsi 4 kugeza kuri 6, kandi zigomba kugaragara ku gihe, ariko imbuto zeze ntabwo zirabagirana nk'iziri ku kimera.

2.aside ya gibberelike

Bishobora gutuma imbuto zitangira gushya. Igihe cyo kurabya, indabyo 10 ~ 50mg/kg ziterwa cyangwa zigaburirwa inshuro imwe, bishobora kurinda indabyo n'imbuto, bigatera imbuto gukura, bigatera imbuto gukingira ibisasu.

3. Polybulobuzole

Bishobora gukumira ubusa. Gutera polybulobulozole 150mg/kg ku mbuto z’inyanya zifite igihe kirekire cyo kutabyara bishobora kugenzura imikurire yazo idakura, guteza imbere imikurire y’imyororokere, koroshya indabyo n’imbuto, gutera igihe cyo gusarura, kongera umusaruro hakiri kare n’umusaruro wose, no kugabanya cyane indwara n’ibipimo by’indwara z’ibyorezo n’indwara za virusi. Inyanya zikura mu buryo butagira iherezo zavuwe na polybulobulozole mu gihe gito cyo kuzirwanya kandi zishobora kongera gukura nyuma yo guterwa, ibyo bikaba byarafashije mu kongera imbaraga z’igiti no kurwanya indwara.

Iyo bibaye ngombwa, kugenzura byihutirwa bishobora gukorwa mu gihe cy'imbuto z'inyanya zo mu mpeshyi, iyo imbuto zimaze kugaragara kandi ingemwe zigomba kugenzurwa, 40mg/kg ni ngombwa, kandi igipimo gishobora kongerwa uko bikwiye, na 75mg/kg ni ngombwa. Igihe cyiza cyo gukumira polybulobuzole ku gipimo runaka ni nk'ibyumweru bitatu. Iyo kugenzura ingemwe ari nyinshi, aside gibberellic ya 100mg/kg ishobora gusukwa ku buso bw'amababi hanyuma hongerwemo ifumbire ya azote kugira ngo yoroherwe.

4.Chlormequat chloride

Ishobora gukumira ubusa. Mu gihe cyo guhinga ingemwe z'inyanya, rimwe na rimwe bitewe n'ubushyuhe bwo hanze buba buri hejuru cyane, ifumbire nyinshi cyane, ubucucike bwinshi cyane, gukura vuba cyane n'izindi mpamvu ziterwa n'ingemwe, uretse gutera ingemwe zitandukanye, kugenzura kuhira, kongera umwuka, bishobora kuba amababi 3 ~ 4 kugeza ku minsi 7 mbere yo gutera, hamwe na 250 ~ 500mg / kg kuhira ubutaka bw'ibimera bugufi, kugira ngo hirindwe gukura kwa.
Ingemwe nto, ifite urwego ruto rw’ingagi, ishobora guterwa, ku kibabi cy’ingemwe n’ubuso bw’igishishwa bigapfukwa neza n’ibitonyanga bito bidafite urugero rw’ingagi; Iyo ingemwe ari nini kandi urwego rw’ingagi ruremereye, zishobora guterwa cyangwa guterwa.

Muri rusange ubushyuhe buri hagati ya 18 na 25°C, hitamo iminsi yo gukoresha kare, ikererewe cyangwa iy'ibicu. Nyuma yo gukoresha, guhumeka bigomba kubuzwa, uburiri bukonje bugomba gupfukwa n'amadirishya, greenhouse igomba gufungwa ku gipangu cyangwa gufunga inzugi n'amadirishya, kongera ubushyuhe bw'umwuka no gutuma umuti w'amazi winjira. Ntukanywe amazi mu gihe cy'umunsi umwe nyuma yo gukoresha kugira ngo wirinde kugabanya ubushobozi bwo gukoresha.
Ntibishobora gukoreshwa saa sita z'amanywa, kandi ingaruka zitangira nyuma y'iminsi 10 nyuma yo gutera, kandi ingaruka zishobora gukomeza kuba mu gihe cy'amasaha 20-30. Niba ingemwe zitagaragara nk'izidafite umusaruro, ni byiza kudafata umuceri mugufi, nubwo ingemwe z'inyanya zaba ndende, inshuro zo gukoresha umuceri mugufi ntizigomba kuba nyinshi cyane, kurenga inshuro 2 birakwiye.
