|Abstract|

Kusetshenziswa utshani be-ryegrass njengento yokuhlola, indlela yokwenza ipulaki ye-tray ye-32-tray matrix yasetshenziswa ukutadisha imiphumela yamazinga okutshala (7, 14 izinhlamvu/ithreyi) ezivunweni ezintathu ze-ryegrass ezitshalwa ngokukhanya okumhlophe kwe-LED (ngomhla we-17, wama-34). , 51 days) umthelela kwisivuno.Imiphumela ibonisa ukuthi i-ryegrass ingakhula ngokujwayelekile ngaphansi kokukhanya okumhlophe kwe-LED, futhi isivinini sokuvuselela siyashesha ngemva kokusikwa, futhi ingakhiqizwa ngezindlela eziningi zokuvuna.Izinga lembewu libe nomthelela omkhulu esivunweni.Ngesikhathi sokusikwa okuthathu, isivuno sezinhlamvu eziyi-14/ithreyi sasiphezulu kunezinhlamvu eziyisi-7 / ithreyi.Isivuno salezi zilinganiso zokuhlwanyela ezimbili sibonise inkambiso yokuqala yehla bese ikhula.Isamba sesivuno sokusanhlamvu okungu-7/ithreyi kanye nezinhlamvu ezingu-14/ithreyi kube ngu-11.11 kanye no-15.51 kg/㎡, ngokulandelana, futhi anamandla okusetshenziswa kwezentengiso.

Izimpahla nezindlela

Izinto Zokuhlola kanye Nezindlela

Izinga lokushisa embonini yezitshalo lalingu-24±2 °C, umswakama ohlobene wawungu-35%–50%, futhi ukugxila kwe-CO2 kwaba ngu-500±50 μmol/mol.Ukukhanya kwephaneli ye-LED emhlophe enosayizi ongu-49 cm×49 cm kwasetshenziselwa ukukhanyisa, futhi isibani sephaneli sibekwe ngo-40 cm ngaphezu kwethreyi yepulaki.Isilinganiso se-matrix yi-peat: i-perlite: i-vermiculite = 3:1:1, engeza amanzi ahlutshiwe ukuze uxube ngokulinganayo, lungisa okuqukethwe kwamanzi ku-55% ~ 60%, futhi ukugcine amahora angu-2 ~ 3 ngemva kokuba i-matrix imunca ngokugcwele amanzi. bese uyifaka ngokulinganayo ku-54 cm × 28 cm kupulaki enezimbobo ezingama-32.Khetha imbewu ekhuluphele futhi elinganayo ngosayizi wokuhlwanyela.

Idizayini yokuhlola

Ukukhanya kokukhanya kwe-LED emhlophe kusethelwe ku-350 μmol/(㎡/s), ukusatshalaliswa kwe-spectral kunjengoba kukhonjisiwe emfanekisweni, isikhathi sobumnyama bokukhanya singu-16 h/8 h, futhi isikhathi sokukhanya singu-5:00 ~ 21:00.Ukuminyana kwembewu okubili kwezinhlamvu eziyisi-7 neziyi-14/umgodi kwakumiselwe ukuhlwanyelwa.Kulesi sivivinyo, imbewu yahlwanyelwa ngoNovemba 2, 2021. Ngemva kokuhlwanyela, yatshalwa ebumnyameni.Ukukhanyisa kwaqalwa ngoNovemba 5. Ngesikhathi sokulima okulula, isisombululo sezakhi zeHoagland sengezwe ethreyini yezithombo.

I-Spectrum yokukhanya okumhlophe kwe-LED

Izinkomba Zokuvuna kanye Nezindlela

Ukuqaphela ukuthi lapho ukuphakama okumaphakathi kwezitshalo kufinyelela ekuphakameni kokukhanya kwephaneli, kuvuna.Banqunywa ngoNovemba 22, Disemba 9 noDisemba 26, ngokulandelana, ngesikhawu sezinsuku eziyi-17.Ubude bezinhlanga babungu-2.5±0.5 cm, futhi izitshalo zakhethwa ngokungahleliwe emigodini engu-3 ngesikhathi sokuvuna, futhi utshani be-ryegrass obuvuniwe balinganiswa futhi barekhodwa, futhi isivuno ngemitha yesikwele sabalwa ngefomula (1).I-Yeld, W iyisisindo esisha esikhulayo sezinhlanga ezisikwayo.

Imiphumela kanye nokuhlaziya

Ngokwesilinganiso sesivuno, izitayela zesivuno sokuminyana okubili kokutshala kwakuyisitshalo sokuqala > isitshalo sesithathu > isitshalo sesibili, 24.7 g > 15.41 g > 12.35 g (izinhlamvu ezingu-7/umgodi), 36.6 g > 19.72 g, ngokulandelana.＞16.98 g (amaphilisi angu-14/imbobo).Bekunomehluko omkhulu phakathi kokuminyana okubili kokutshala esivunweni sesilimo sokuqala, kodwa awukho umehluko omkhulu phakathi kwesitshalo sesibili, sesithathu kanye nesivuno esiphelele.

Imithelela yezinga lokuhlwanyela kanye nezikhathi zokusika izinhlanga ekuvunweni kwe-ryegrass

Ngokwezinhlelo ezihlukene zokusika, umjikelezo wokukhiqiza ubalwa.Umjikelezo wokusika owodwa yizinsuku ezingama-20;ukusika okubili kuyizinsuku ezingama-37;futhi ukusikwa okuthathu yizinsuku ezingama-54.Izinga lokuhlwanyela lezinhlamvu ezingu-7/umgodi libe nesivuno esiphansi kakhulu, kuphela u-5.23 kg/㎡.Lapho izinga lokuhlwanyela liyizinhlamvu ezingu-14/imbobo, isivuno esinqwabelene sokusikwa okungu-3 sasingu-15.51 kg/㎡, esasiphindwe izikhathi ezi-3 kunesivuno sezinhlamvu ezingu-7/imbobo yokusika isikhathi esingu-1, futhi sasiphezulu kakhulu kunezinye izikhathi zokusika.ubude bomjikelezo wokukhula wokusikeka kathathu babuphindwe izikhathi ezingu-2,7 kunokwesika okukodwa, kodwa isivuno sasicishe siphindwe izikhathi ezi-2 kunesokunqunywa okukodwa.Kwakungekho umehluko obalulekile esivunweni lapho izinga lokuhlwanyela laliyizinhlamvu ezingu-7/imbobo ukusika izikhathi ezi-3 kanye nezinhlamvu ezingu-14/umgodi ukusika izikhathi ezi-2, kodwa umehluko womjikelezo wokukhiqiza phakathi kwalezi zindlela ezimbili kwakuyizinsuku eziyi-17.Lapho izinga lokuhlwanyela kuyizinhlamvu eziyi-14/imbobo esike kanye, isivuno sasingehlukanga kakhulu kuleso sika-7 izinhlamvu/umgodi osikwe kanye noma kabili.

Isivuno se-ryegrass sigundwe izikhathi ezingu-1-3 ngaphansi kwamazinga amabili wokuhlwanyela

Ekukhiqizeni, inani elifanelekile lamashalofu, ukuphakama kweshalofu, kanye nezinga lokuhlwanyela kufanele kuklanywe ukwandisa isivuno endaweni ngayinye, futhi ukugunda okufika ngesikhathi kufanele kuhlanganiswe nokuhlolwa kwekhwalithi yokudla ukuze kuthuthukiswe ikhwalithi yomkhiqizo.Izindleko zomnotho ezifana nembewu, abasebenzi, nokugcinwa kotshani obusha nakho kufanele kucatshangelwe.Njengamanje, imboni yamadlelo nayo ibhekene nezinkinga zohlelo lokusatshalaliswa kwemikhiqizo engaphelele kanye nezinga eliphansi lokudayiswa.Ingasatshalaliswa ezindaweni zasendaweni kuphela, okungekuhle ukuthi kuqhamuke inhlanganisela yotshani nemfuyo ezweni lonke.Ukukhiqizwa kwefekthri yezitshalo akukwazi nje ukufinyeza umjikelezo wokuvuna we-ryegrass, kuthuthukise izinga lokuphumayo endaweni ngayinye, futhi kuzuze ukunikezwa konyaka kotshani obusha, kodwa futhi kungakha amafekthri ngokuya ngokusatshalaliswa kwendawo kanye nezinga lezimboni zokufuywa kwezilwane, ukunciphisa izindleko zokuthutha.

Isifinyezo

Ukufingqa, kungenzeka ukukhiqiza i-ryegrass ngaphansi kwesibani se-LED.Isivuno sezinhlamvu eziyisi-7/imbobo kanye nezinhlamvu eziyi-14/imbobo zombili zaziphakeme kunezivuno zokuqala, okubonisa inkambiso efanayo yokuqala ukuncipha bese anda.Isivuno salezi zilinganiso zembewu ezimbili sifinyelele ku-11.11 kg/㎡ kanye no-15.51 kg/㎡ ngezinsuku ezingu-54.Ngakho-ke, ukukhiqizwa kwe-ryegrass emafekthri ezitshalo kunamandla okusetshenziselwa ukuhweba.
