Chiedza chinotamba chinzvimbo chakakosha mukukura kwechirimwa. Kuburikidza neThephetonynthesis, zvirimwa zvinokwenenzvera simba renje muMakemikari simba, izvo zvinotsigira kukura kwavo uye iyo synthesis yezvinhu zvinodiwa pakukura. Nekudaro, zvidyarwa zvakasiyana zvine zvisizvo zvinodikanwa zvechiedza. Iyo spectrum uye kusimba kwechiedza isinganyorerwe nekumhanya kwekukura kwechirimwa asi zvakare kukanganisa morphology yavo, kuyerera, uye chibereko. MuGreenhouse kurima, kusarudza iyo chaiyo spectrum uye kuwanda kwechiedza kwakakosha kuti uwedzere kurapa goho uye mhando. Munyaya ino, isu tichaongorora kuti kusakwana kwechiedza uye kushushikana kwakasiyana kwakadii kuita zvirimwa zvakasiyana-siyana uye kuti varimi vorima sei vanogona kushandisa zivo iyi kukurira kurima chirimwa kukura.
1. Chiedza chiedza chinobata sei kukura chirimwa?
Iyo light spectrum inoreva huwandu hwenzvimbo yemazwi echiedza, uye chikamu chimwe nechimwe chezvirevo chine chekuita kwakasiyana pakukura kwechirimwa. Chiitiko chakajairika chiedza chinosanganisira bhuruu, tsvuku, uye girini mwenje, uye imwe neimwe ine mhedzisiro yakasarudzika pane zvidyarwa.
1.1 Blue Light
Blue Chiedza (wavelengths pakati pe450-495 nm) chakakosha kuti kurima kukura, kunyanya maererano neshizha remagetsi uye zvakazara morphology. Blue Light inosimudzira photosynthesis uye chlorophyll synthesis, nekukonzera nekuvandudza kushanda kwe photosynthesis. Kune mashizha miriwo kunge lettuce uye sipinachi, bhuruu yebhuruu inonyanya kubatsira pakuwedzera shizha saizi uye density.
1.2 mwenje tsvuku
Tsvuku mwenje (wavelengths pakati pe620-750 nm) chimwezve chinhu chakakosha chiedza chechiedza chezvidyarwa. Inoita basa rakakosha mukuyerera, kubereka, uye kukura kwakazara kwerimwa. Chiedza chitsvuku chinomutsa kusimuka uye kunotsigira kugadzirwa kwe phytochrome, iyo inopesvedzera kurima kukura uye kubereka matanho.
2. Chiedza kusimba uye kukanganisika kwacho pane kukura kwezvirimwa
Nepo mwenje wechiedza ukakosha, kukura kwechiedza kunoitawo basa rakakosha mukuvandudza chirimwa. Chiedza chakajeka chinoreva huwandu hwechiedza chiripo kune zvidyarwa, uye zvinogona kukanganisa chiyero che photosynthesis, kukura kwechirimwa, uye hutano hwese hwezvirimwa.
2.1 Yakakura Chiedza Kuwedzera
Yakanyanya kuwanda kwechiedza inokurudzira yakasimba photosynthesis, inotungamira kukurumidza kurima kukura uye kuwedzera kubereka. Zvirimwa zvakadai somatata uye pepper inoda zvakanyanya kuwanda kwechiedza kubereka chibereko zvakanaka. Nekudaro, zvakanyanya kuwanda kwechiedza kunogona kukonzerawo kushushikana kune zvidyarwa, zvichitungamira kune mashizha kupisa kana kudzoserwa kukura. Zvakakosha kuyera kuwanda kwechiedza kuti uve nechokwadi chehutano hwakakwana hwehutano.
2.2 Yakadzika yakaderera kuwedzera
Yakadzika yechiedza simba inogona kudzikisira photosynthesis, inotungamira kukurumidza kukura uye zvidiki zvidiki. Nepo zvimwe zvirimwa, zvakadai se mamwe magirazi egirazi, anogona kushivirira zvakaderera mwenje, zvirimwa zvakawanda zvinoda kukwana zvakakwana kuti ubudirire. Greenhouse varimi vanogona kuwedzera zvisikwa zvakasikwa nemwenje wekunyepedzera, kunyanya mukati memwedzi yechando kana mumatunhu ane chiedza chezuva.
Nokunzwisisa kukanganiswa kwechiedza chiitiko uye kusimba, varimi vemahara, vanokwanisa kurongedza mwenje wavo wekusimudzira zvirimwa zvine hutano uye zvinogadzirwa. Kushandisa musanganiswa wechisikigo uye seyekuwedzera mwenje
Nemidziyo chaiyo uye nzira dzekutonga, dzakadai sekudzora zviyero zvemwenje uye uchishandisa magetsi akasarudzika, kurima greenhouse kunogona kutsigira hutano hwakanaka gore-kutenderera, kunyange mumwaka wakasarudzika.
Tikugashirei kuve nehanya zvakare hurukuro nesu.
