Tsvagiridzo pamusoro peMhedzisiro yeMwaranzi we LED paGoho Rinowedzera Mhedzisiro yeHydroponic Lettuce nePakchoi muGreenhouse munguva yechando
[Pfupiso] Chando muShanghai chinowanzosangana nekupisa kwakaderera uye zuva rakaderera, uye kukura kwemiriwo yemashizha ehydroponic mugreenhouse kunononoka uye nguva yekugadzira yakareba, izvo zvisingakwanise kusangana nezvinodiwa nemusika. Mumakore achangopfuura, mwenje yekuwedzera ye LED plant yakatanga kushandiswa mukurima nekugadzira greenhouse, kusvika pamwero wakati, kutsiva zvikanganiso zvekuti chiedza chinounganidzwa zuva nezuva mugreenhouse hachigone kusangana nezvinodiwa nekukura kwezvirimwa kana chiedza chechisikigo chisina kukwana. Mukuyedza uku, mhando mbiri dzemwenje ye LED ine mhando dzakasiyana dzechiedza dzakaiswa mugreenhouse kuti dziite kuyedza kwekutsvaga kwekuwedzera kugadzirwa kwe hydroponic lettuce ne green stem muchando. Mhedzisiro yacho yakaratidza kuti mhando mbiri dzemwenje ye LED dzinogona kuwedzera huremu hutsva pamuti wega wega we pakchoi ne lettuce. Mhedzisiro inowedzera goho ye pakchoi inonyanya kuratidzwa mukuvandudzwa kwemhando yese yekunzwa senge kuwedzera kwemashizha nekukora, uye mhedzisiro inowedzera goho ye lettuce inonyanya kuratidzwa mukuwedzera kwehuwandu hwemashizha nemafuta akaoma.

Chiedza chikamu chakakosha chekukura kwezvirimwa. Mumakore achangopfuura, mwenje dze LED dzave dzichishandiswa zvakanyanya mukurima nekugadzira munzvimbo inodziya nekuda kwehuwandu hwadzo hwekuchinja kwemagetsi, spectrum inogadziriswa, uye hupenyu hurefu hwebasa [1]. Munyika dzekunze, nekuda kwekutanga kwekutsvagisa kwakabatana uye sisitimu yekutsigira yakakura, kugadzirwa kwemaruva, michero nemiriwo mikuru kune nzira dzakakwana dzekuwedzera chiedza. Kuunganidzwa kwedata rakawanda rekugadzira chairo kunobvumirawo vagadziri kufanotaura zvakajeka mhedzisiro yekuwedzera kugadzirwa. Panguva imwe chete, kudzoka mushure mekushandisa sisitimu yemwenje yekuwedzera ye LED kunoongororwa [2]. Zvisinei, tsvakiridzo zhinji dzemuno dziripo pamusoro pemwenje yekuwedzera dzakanangana nemhando yemwenje midiki uye kugadzirisa kwespectral, uye hadzina nzira dzekuwedzera chiedza dzinogona kushandiswa mukugadzira chaiko[3]. Vagadziri vazhinji vemuno vanoshandisa zvakananga mhinduro dzemwenje dzekunze dziripo pavanoshandisa tekinoroji yekuwedzera chiedza mukugadzira, zvisinei nemamiriro ekunze enzvimbo yekugadzira, mhando dzemiriwo inogadzirwa, uye mamiriro ezvivakwa nemidziyo. Pamusoro pezvo, mutengo wakakwira wemidziyo yekuwedzera chiedza uye kushandiswa kwesimba rakawanda zvinowanzo kukonzera musiyano mukuru pakati pegoho chairo rezvirimwa nekudzoka kwehupfumi uye mhedzisiro inotarisirwa. Mamiriro ezvinhu akadai pari zvino haabatsiri mukuvandudzwa nekusimudzirwa kwetekinoroji yekuwedzera chiedza uye kuwedzera kugadzirwa munyika. Nokudaro, zvakakosha kuisa zvigadzirwa zve LED zvekuwedzera zvemwenje zvakura munzvimbo chaiyo yekugadzira mumba, kugadzirisa nzira dzekushandisa, uye kuunganidza data rakakodzera.

Mwaka wechando ndiwo mwaka apo miriwo mitsva inokura inodiwa zvikuru. Magreenhouse anogona kupa nzvimbo yakakodzera yekukura kwemiriwo ine mashizha munguva yechando kupfuura minda yekurima yekunze. Zvisinei, chinyorwa chakaratidza kuti mamwe magreenhouse akasakara kana asina kuchena zvakanaka ane chiedza chinopfuudzwa pasi pe50% munguva yechando. Pamusoro pezvo, mamiriro ekunze ekunaya kwenguva refu anowanzoitikawo munguva yechando, izvo zvinoita kuti greenhouse ive munzvimbo ine tembiricha yakaderera uye ine chiedza chakaderera, izvo zvinokanganisa kukura kwakajairika kwezvirimwa. Chiedza chave chinhu chinodzivisa kukura kwemiriwo munguva yechando [4]. Green Cube yakaiswa mukugadzirwa chaiko inoshandiswa mukuyedza. Sisitimu yekudyara miriwo ine mashizha inoyerera zvishoma inoenzaniswa neSignify (China) Investment Co., Ltd.'s maviri ma LED top light modules ane blue light ratios dzakasiyana. Kudyara lettuce nepakchoi, ayo ari miriwo miviri ine mashizha anodiwa zvakanyanya pamusika, ine chinangwa chekudzidza kuwedzera chaiko mukugadzirwa kwemiriwo ine mashizha ehydroponic nemwenje yeLED mugreenhouse yechando.

Zvinhu zvinoshandiswa pakuedza

Zvinhu zvakashandiswa mukuyedza kwacho zvaive lettuce nemiriwo ye packchoi. Mhando ye lettuce, Green Leaf Lettuce, inobva kuBeijing Dingfeng Modern Agriculture Development Co., Ltd., uye mhando ye pakchoi, Brilliant Green, inobva kuHorticulture Institute of Shanghai Academy of Agricultural Sciences.

Nzira yekuyedza

Kuedza uku kwakaitwa muWenluo type glass greenhouse yeSunqiao base yeShanghai green cube Agricultural Development Co., Ltd. kubva muna Mbudzi 2019 kusvika Kukadzi 2020. Kuedza kwakaitwa kaviri. Kuedza kwekutanga kwaive pakupera kwa2019, uye kutenderera kwechipiri kwaive pakutanga kwa2020. Mushure mekudyara, zvinhu zvekuedza zvakaiswa muimba yechiedza chekugadzira kuti zvikure mhodzi, uye kudiridza kwemvura kwakashandiswa. Munguva yekukwidza mhodzi, mushonga wekudya wemiriwo yehydroponic ine EC ye1.5 uye pH ye5.5 wakashandiswa pakudiridza. Mushure mekunge mhodzi dzakura kusvika pamashizha matatu nechikamu chimwe chemoyo, dzakadyarwa pamubhedha wekudyara mhodzi wegreen cube track type shallow flow leafy. Mushure mekudyara, system yekutenderera kwemvura yeshallow flow nutrient solution yakashandisa EC 2 ne pH 6 nutrient solution yekudiridza zuva nezuva. Kudiridza kwaive kwemaminitsi gumi nemvura uye maminitsi makumi maviri mvura yamira. Boka rekudzora (risina chiwedzerwa chemwenje) neboka rekurapa (chiwedzerwa chemwenje cheLED) zvakaiswa mukuyedza. CK yakadyarwa mugreenhouse yegirazi isina chiwedzerwa chemwenje. LB: drw-lb Ho (200W) yakashandiswa kuwedzera chiedza mushure mekudyara mugreenhouse yegirazi. Kuwanda kwechiedza (PPFD) pamusoro pekanzuru yemuriwo wehydroponic kwaive kungangoita 140 μmol/(㎡·S). MB: mushure mekudyara mugreenhouse yegirazi, drw-lb (200W) yakashandiswa kuwedzera chiedza, uye PPFD yaive ingangoita 140 μmol/(㎡·S).

Zuva rekutanga rekudyara kwekuyedza ndiMbudzi 8, 2019, uye zuva rekudyara ndiMbudzi 25, 2019. Nguva yekuwedzera yeboka rekuyedza ndeye 6:30-17:00; zuva rechipiri rekudyara kwekuyedza ndiZvita 30, 2019 Zuva, zuva rekudyara ndiNdira 17, 2020, uye nguva yekuwedzera yeboka rekuyedza ndi4:00-17:00
Mumamiriro ekunze ane zuva munguva yechando, greenhouse ichavhura denga rezuva, firimu repadivi nefeni kuti zvipinde mhepo zuva nezuva kubva 6:00-17:00. Kana tembiricha yakaderera husiku, greenhouse ichavhara skylight, firimu repadivi nefeni na17:00-6:00 (zuva rinotevera), uye ichavhura keteni rekudzivirira kupisa mugreenhouse kuti ichengetedze kupisa husiku.

Kuunganidzwa kweData

Kureba kwemuti, huwandu hwemashizha, uye huremu hutsva pamuti wega wega zvakawanikwa mushure mekukohwa zvikamu zveQingjingcai nelettuce zviri pamusoro pevhu. Mushure mekuyera huremu hutsva, hwakaiswa muovheni ndokuomeswa pa75℃ kwemaawa makumi manomwe nemaviri. Mushure mekupedza, huremu hwakaoma hwakaonekwa.

Kuongorora Data

Verenga mashandiro ekushandisa chiedza (LUE, Light Use Efficiency) zvichienderana nefomura inotevera:
LUE (g/mol) = goho remuriwo pachikamu chimwe nechimwe/huwandu hwese hwechiedza chinowanikwa nemuriwo pachikamu chimwe nechimwe kubva pakudyara kusvika pakukohwa
Verengai zviri mukati mezvinhu zvakaoma zvichienderana nefomura inotevera:
Huremu hwezvinhu zvakaoma (%) = huremu hwakaoma pachirimwa chimwe nechimwe/huremu hutsva pachirimwa chimwe nechimwe x 100%
Shandisa Excel2016 neIBM SPSS Statistics 20 kuti uongorore data riri mukuyedza uye uongorore kukosha kwemusiyano.
