Mhedzisiro yezvinomera kukura regulators pane zvinokambaira bentgrass pasi pemamiriro ekupisa, munyu uye kusanganisa kushushikana

Ichi chinyorwa chakaongororwa zvinoenderana neScience X's edhita maitiro uye marongero.Vapepeti vakasimbisa hunhu hunotevera uku vachiona kuvimbika kwezviri mukati:
Ongororo ichangoburwa yakaitwa nevaongorori veOhio State University yakaratidza hukama hwakaoma pakati pezvinodzora kukura kwezvirimwa uye kuramba kwezvinokambaira bentgrass kune dzakasiyana siyana zvinonetsa kwezvakatipoteredza, sekupisa uye kushushikana kwemunyu.
Creeping bentgrass (Agrostis stolonifera L.) imhando inoshandiswa zvakanyanya uye yakakosha mune zvehupfumi inowanzoshandiswa pamakosi egorofu muUnited States yese.Mumunda, zvidyarwa zvinowanzooneswa kushushikana kwakawanda panguva imwe chete, uye kudzidza kwakazvimiririra kwekunetseka kunogona kunge kusina kukwana.Kushungurudzika kwakadai sekunetseka kwekupisa uye kushushikana kwemunyu kunogona kukanganisa phytohormone mazinga, izvo zvinogona kukanganisa kukwanisa kwechirimwa kushivirira kushushikana.
Masayendisiti akaita ongororo dzakatevedzana kuti aone kana mazinga ekupisa uye kushushikana kwemunyu kunogona kukanganisa hutano hwezvinokambaira bentgrass, uye kuongorora kana kushandiswa kwezvinomera zvinokura zvingavandudza hutano hwechirimwa mukushushikana.Vakaona kuti mamwe magadzirirwo ekukura kwechirimwa anogona kuvandudza kushivirira kwekunetseka kwezvinokambaira bentgrass, kunyanya pasi pekupisa uye kushushikana kwemunyu.Mhedzisiro iyi inopa mikana yekugadzira nzira nyowani dzekudzikamisa mhedzisiro yezvakatipoteredza zvinonetsa pahutano hweturf.
Iko kushandiswa kwezvimiro zvekukura kwezvirimwa zvinoita kuti zvikwanise kukwidziridza kukura uye kusimudzira kwezvinokambaira bentgrass kunyangwe pamberi pezvinonetsa.Kuwanikwa uku kune vimbiso huru yekuvandudza turf mhando uye kusimba pasi pemamiriro akasiyana ezvakatipoteredza.
Ichi chidzidzo chinosimbisa kudyidzana kwakabatana pakati pezvimiro zvekukura kwezvirimwa uye zvinonetsa kwezvakatipoteredza, zvichiratidza kuomarara kweturfgrass physiology uye kugona kweakarongedzerwa manejimendi maitiro.Tsvakurudzo iyi inopawo maonero anoshanda anogona kubatsira zvakananga turfgrass mamaneja, agronomists, uye vanoita zvezvakatipoteredza.
Sekureva kwemunyori pamwe naye Arlie Drake, mubatsiri purofesa wezvekurima paClark State University, "Pazvinhu zvese zvatinoisa pauswa, ndagara ndichifunga kuti maregulator ekukura akanaka, kunyanya HA synthesis inhibitors.Kunyanya nekuti ivo vanewo mabasa, kwete kudzora kukura kwakamira. "
Munyori wekupedzisira, David Gardner, purofesa we turf science paOhio State University.Inoshanda zvakanyanya pakudzora sora mumaswani uye zvishongo, pamwe nekushushikana kwefiziology semumvuri kana kupisa kunetseka.

Kana ukasangana netaipa, zvisizvo, kana kuti uchida kuendesa chikumbiro chekugadzirisa zviri papeji ino, ndapota shandisa fomu iri.Pamibvunzo yakajairika, ndapota shandisa fomu redu rekuonana.Kuti uwane mhinduro dzakajairika, shandisa chikamu chemashoko eruzhinji pazasi (tevera zvinongedzo).
Mhinduro yako yakakosha kwatiri.Nekudaro, nekuda kwehuwandu hwemeseji, hatigone kuvimbisa mhinduro yemunhu.
