Mumakore achangopfuura, kwave nemichero yakawanda isina mwaka, uye pakutanga kwechirimo, mastrawberry matsva nemapichi achaonekwa pamusika. Michero iyi inoibva sei isina mwaka? Kare, vanhu vaifunga kuti uyu muchero unorimwa mugreenhouse. Zvisinei, nekuramba uchionekwa mastrawberry asina mhodzi, mazambiringa asina mhodzi, uye manwiwa asina kusimba mumakore achangopfuura, vanhu vakatanga kusava nechokwadi kana michero iyi inoita kunge mikuru uye mitsva isina mwaka ichinyatsonaka? Yakachengeteka zvechokwadi here?
Kuonekwa kwemichero iyi isina chimiro kwakakwezva vanhu pakarepo. Mahormone akapindawo mumaonero evanhu. Vamwe vanhu, kuti vapfupise kukura kwezvirimwa uye vawane purofiti yakakura, vanoshandisa mahormone pamichero nemiriwo yakawanda isina mwaka kuti vakwanise kuibva nekukurumidza. Ndosaka mimwe michero ichitaridzika zvakanaka asi ichinaka zvakaipa.
Maitiro evatengesi vasina hunhu hwekuwedzera mahormone mumiriwo nemichero akaita kuti vanhu vazhinji vasade mahormone, uye mudzori wekukura kwezvirimwa asina rombo rakanaka haadiwiwo nevanhu nekuda kwemhedzisiro yawo yakafanana nemahormone. Saka chii chaizvo chinonzi mudzori wekukura kwezvirimwa? Chine chekuita nemahormone here? Chine hukama hwerudzii? Tevere, ngatitaurei nezve chii chinonzi mudzori wekukura kwezvirimwa uye mabasa acho ndeapi?
Mushonga wekukura kwezvirimwa unoshandiswa mukugadzira zvinhu zvakasikwa (kana kuti zvakatorwa kubva mutupukanana) zvine maitiro ekukura nekukura akafanana nehomoni yezvirimwa zvechisikigo. Chinhu chekugadzira chinoshandiswa mukurima mushure mekunge vanhu vanzwisisa chimiro uye mashandiro ehomoni yezvirimwa zvechisikigo, kuitira kuti vagone kudzora kukura kwezvirimwa zvinobudirira, kuzadzisa chinangwa chekudzikamisa goho uye kuwedzera goho, kuvandudza mhando, uye kuwedzera kuramba kwegoho. Vaya vanowanzo dzora kukura kwezvirimwa vanosanganisira DA-6, Forchlorfenuron, sodium nitrite, brassinol, gibberellin, nezvimwewo.
Zvinodzora kukura kwezvirimwa zvine mashandisirwo akasiyana-siyana uye zvinosiyana pakati pemhando yezvirimwa nechirimwa chaunoda. Semuenzaniso:
Dzora kumera uye kusakura kwemiti; kurudzira midzi; kurudzira kureba kwemasero nekupatsanurwa; dzora bundu repadivi kana kurima; Dzora mhando yemiti (kudzivirira kugara kwenguva pfupi uye kwakasimba); dzora kutunga kwemaruva kana bonde remurume neremukadzi, kurudzira michero isina mwana; maruva nemichero yakavhurika, dzora kudonha kwemichero; dzora chimiro kana nguva yekuibva kwemichero; wedzera kudzivirira kushushikana (kurwisa zvirwere, kurwisa kusanaya kwemvura, kurwisa munyu uye kurwisa kutonhora); Wedzera kugona kunwisa fetereza; wedzera shuga kana kuchinja acidity; vandudza kunaka neruvara; Kukurudzira kuburitswa kwelatex kana resin; kubvisa mashizha kana kufungidzira (kubatsira kukohwa kwemuchina); kuchengetedza, nezvimwewo.
Zvinoenderana neRegulations on the Administration of Pesticides, vanodzora kukura kwezvirimwa vari muchikamu chekutonga mishonga yezvipembenene, uye hurongwa hwekunyoresa nekugadzirisa mishonga yezvipembenene hunofanira kuitwa zvichienderana nemutemo. Vanodzora kukura kwezvirimwa vese vanogadzirwa, vanotengeswa uye vanoshandiswa muChina vanofanirwa kunyoreswa semishonga yezvipembenene. Patinoshandisa vanodzora kukura kwezvirimwa, tinofanira kuishandisa zvichienderana nemirairo uye kutora matanho akanaka ekudzivirira kuchengetedzeka kwevanhu, zvipfuyo nemvura yekunwa.
