|Abstract|

Ichishandisa ryegrass sechinhu chekuyedza, iyo 32-tray plug tray matrix tsika nzira yakashandiswa kudzidza mhedzisiro yemitengo yekudyara (7, 14 tsanga/tireyi) pamikoho mitatu yeryegrass inorimwa ne LED chena mwenje (yechi17, 34th. , 51 days) kukanganisa pagoho.Mhedzisiro yacho inoratidza kuti ryegrass inogona kukura yakajairika pasi peiyo chena mwenje LED, uye kukurumidza kuberekwa patsva inokurumidza mushure mekucheka, uye inogona kugadzirwa zvinoenderana neakawanda nzira dzekukohwa.Chiyero chembeu chakaita zvakakosha pagoho.Munguva yekucheka katatu, goho rezviyo gumi nemana / tray rakanga rakakwirira kudarika 7 zviyo / tray.Zvibereko zvemhando mbiri dzembeu dzakaratidza maitiro ekutanga kudzikira uyezve kuwedzera.Izvo zvakazara goho zve7 zviyo / tireyi uye gumi nemana / tireyi yaive 11.11 uye 15.51 kg/㎡, zvichiteerana, uye vane mukana wekutengesa kushandiswa.

Zvishandiso uye Nzira

Zvishandiso Zvokuedzwa uye Nzira

Tembiricha mufekitari yechirimwa yaive 24±2 °C, hunyoro hwehukama hwaive 35% -50%, uye CO2 yekumisikidza yaive 500±50 μmol/mol.Chiedza chemwenje che LED chine saizi ye 49 cm × 49 cm yakashandiswa kuvhenekera, uye mwenje wepaneti wakaiswa 40 cm pamusoro pe plug tray.Chiyero chematrix ndeye peat: perlite: vermiculite = 3: 1: 1, wedzera mvura yakasvibiswa kuti isanganise zvakaenzana, gadzirisa zvinyorwa zvemvura kusvika 55% ~ 60%, uye uzvichengete kwemaawa 2 ~ 3 mushure mokunge matrix anyatsotora mvura. wobva waiisa zvakaenzana mu 54 cm × 28 cm mune 32-hole plug.Sarudza mhodzi dzakakora uye dzakafanana pakukura pakudyara.

Test Design

Kusimba kwechiedza cheiyo chena LED yakaiswa ku 350 μmol/(㎡/s), kugovaniswa kwe spectral kunoratidzwa mumufananidzo, nguva yechiedza-yakasviba i16 h/8 h, uye nguva yechiedza i5:00 ~. 21:00.Mbeu mbiri dzakasimba dze7 uye 14 tsanga/gomba dzakagadzirirwa kudyarwa.Mukuedza uku, mbeu dzakadyarwa munaNovember 2, 2021. Mushure mekudyara, dzakarimwa murima.Kuvhenekera kwakatangwa munaNovember 5. Munguva yekurima kwechiedza, Hoagland nutrient solution yakawedzerwa kune seedling tray.

Zviratidzo zveKukohwa uye Nzira

Kucherechedza kuti kana avhareji urefu hwemiti inosvika pakukwirira kwechiedza chepaneti, kukohwa.Vakachekwa munaNovember 22, Zvita 9 uye Zvita 26, zvichiteerana, nepakati pemazuva gumi nemanomwe.Hurefu hwemashanga hwakanga huri 2.5 ± 0.5 cm, uye zvinomera zvakasarudzwa zvisina kurongwa mumakomba matatu panguva yekukohwa, uye ryegrass yakakohwewa yakayerwa uye yakanyorwa, uye goho pamita yemamita yakaverengerwa mufomula (1).Goho, W ndiyo yakawedzera huremu hutsva hwemashanga ega ega ekucheka.

Migumisiro uye Analysis

Paavhareji yegoho, maitiro egoho rekudyara tsinga mbiri dzaive chirimwa chekutanga > chirimwa chechitatu > chirimwa chechipiri, 24.7 g > 15.41 g > 12.35 g (7 tsanga/gomba), 36.6 g > 19.72 g, zvichiteerana.＞16.98 g (14 capsules/gomba).Pakave nemusiyano mukuru pakati pemiviri miviri yekudyara mugoho rechirimwa chekutanga, asi pasina musiyano mukuru pakati pechirimwa chechipiri, chechitatu negoho rose.

Mhedzisiro yekukura kwekudyara uye nguva yekucheka mashanga pagoho rehuswa

Zvinoenderana neakasiyana ekucheka zvirongwa, kutenderera kwekugadzira kunoverengerwa.Imwe yekucheka kutenderera mazuva makumi maviri;kuchekwa kuviri mazuva makumi matatu nemanomwe;uye kuchekwa kutatu mazuva makumi mashanu nemana.Kudyarwa kwembeu 7/gomba ndiko kwaive negoho rakaderera, 5.23 kg/㎡ chete.Kana chiyero chembeu chaive 14 tsanga/gomba, goho rekuwedzera rema3 cuttings raive 15.51 kg/㎡, yaive yakapetwa katatu goho re7 tsanga/gomba kucheka kamwechete, uye yaive yakanyanya kukwirira kupfuura dzimwe nguva dzekucheka.iye kureba kwekutenderera kwekukura kwekucheka katatu kwaive ne 2,7 kupfuura yekucheka kumwe, asi goho raingopeta kanenge ka2 pane rekucheka kumwe.Pakanga pasina misiyano yakakosha mugoho apo chiyero chembeu chaive 7 zviyo / gomba kucheka 3 nguva uye 14 zviyo / gomba kucheka 2 nguva, asi kugadzirwa kutenderera musiyano pakati penzira mbiri yaive mazuva gumi nemanomwe.Kana chiyero chembeu chaive 14 tsanga/gomba rakachekwa kamwe chete, goho rakanga risina kunyanya kusiyana nerezviyo zvinomwe/gomba rakachekwa kamwe chete kana kaviri.

Goho re ryegrass rakachekwa 1-3 nguva pasi pemhando mbiri dzembeu

Mukugadzira, nhamba inonzwisisika yemasherufu, kureba kwesherufu, uye chiyero chembeu chinofanirwa kugadzirwa kuti chiwedzere goho pachikamu chimwe chete, uye kucheka panguva yakakodzera kunofanirwa kusanganiswa nekuongororwa kwehutano hwekudya kuvandudza kunaka kwechigadzirwa.Mari dzehupfumi dzakaita sembeu, vashandi, uye kuchengetedza huswa hutsva zvinofanirwa kutariswa.Parizvino, indasitiri yemafuro yakatarisanawo nematambudziko eiyo isina kukwana chigadzirwa kutenderera sisitimu uye yakaderera kushambadzira mwero.Inogona kungotenderedzwa munzvimbo dzemunharaunda, izvo zvisingakodzeri kuona kusanganiswa kwehuswa nezvipfuyo munyika yose.Kugadzirwa kwefekitori yekudyara hakungopfupikidze kutenderera kwegoho rehuswa, kuvandudza mwero wekubuda pachikamu chimwe chete, uye kuwana gore negore kupihwa huswa hutsva, asi zvakare kunogona kuvaka mafekitori zvichienderana nekugoverwa kwenzvimbo uye chiyero cheindasitiri chekuchengeta mhuka, kudzikisa mitengo yezvinhu.

Summary

Kupfupisa, zvinokwanisika kugadzira ryegrass pasi pemwenje we LED.Goho rezviyo zvinomwe/gomba uye 14 tsanga/gomba zvose zvanga zvakakwirira kudarika zvechirimwa chekutanga, zvichiratidza maitiro akafanana ekutanga kudzikira nekuwedzera.Goho remhando mbiri dzembeu dzakasvika 11.11 kg/㎡ uye 15.51 kg/㎡ pamazuva makumi mashanu nemana.Naizvozvo, kugadzirwa kwe ryegrass mumafekitori ezvirimwa kune mukana wekushandiswa kwekutengesa.
