Hakoreshejwe ubwatsi bwa rye nk'ibikoresho byo kugerageza, uburyo bwo guhingwa bwakoreshejwe mu kwiga ingaruka z'igipimo cy'ibihingwa (ibinyampeke 7, 14/isahani) ku ngaruka eshatu z'ibyatsi bya rye byahinzwe hakoreshejwe urumuri rwa LED (iminsi ya 17, 34, 51) ku musaruro. Ibisubizo bigaragaza ko ubwatsi bwa rye bushobora gukura bisanzwe munsi y'urumuri rwa LED rwera, kandi umuvuduko wo kuvugurura uba vuba nyuma yo gutema, kandi bushobora gukorwa hakurikijwe uburyo bwinshi bwo gusarura. Igipimo cyo gutera imbuto cyagize ingaruka zikomeye ku musaruro. Mu gihe cy'ibice bitatu, umusaruro w'ibinyampeke 14/isahani wari hejuru ugereranije n'uw'ibinyampeke 7/isahani. Umusaruro w'ibinyampeke bibiri byo gutera imbuto wagaragaje ko ubanza kugabanuka hanyuma ukiyongera. Umusaruro wose w'ibinyampeke 7/isahani n'ibinyampeke 14/isahani wari 11.11 na 15.51 kg/㎡, uko bikurikirana, kandi bifite ubushobozi bwo gukoreshwa mu bucuruzi.

Ibikoresho n'Uburyo

Ibikoresho n'uburyo bwo gupima

Ubushyuhe mu ruganda rwari 24±2 °C, ubushyuhe bwari 35%–50%, naho igipimo cya CO2 cyari 500±50 μmol/mol. Itara ry'umweru rya LED rifite ingano ya cm 49×49 ryakoreshejwe mu kumurika, maze itara ry'ibara rishyirwa kuri cm 40 hejuru y'agasanduku k'ibumba. Igipimo cya matrix ni peat: perlite: vermiculite = 3:1:1, ongeramo amazi yaciwe kugira ngo uvange neza, hindura ingano y'amazi kuri 55%~60%, hanyuma uyabike amasaha 2-3 nyuma yuko matrix ifashe amazi neza hanyuma uyishyire kuri cm 54 × 28 mu gasanduku k'imyobo 32. Hitamo imbuto zibyimbye kandi zingana neza zo gutera.

Igishushanyo mbonera cy'ikizamini

Ubushyuhe bw'urumuri rwa LED yera bushyirwa kuri 350 μmol/(㎡/s), ikwirakwizwa rya spectral riri nk'uko bigaragara ku ishusho, igihe cy'umwijima w'urumuri ni amasaha 16/8, naho igihe cy'urumuri ni 5:00~21:00. Ubucucike bubiri bw'imbuto z'ibinyampeke 7 na 14/umwobo bwashyizweho kugira ngo zibibwe. Muri ubu bushakashatsi, imbuto zabibwe ku ya 2 Ugushyingo 2021. Nyuma yo kubiba, zahinzwe mu mwijima. Amatara yatangiye ku ya 5 Ugushyingo. Mu gihe cyo guhinga urumuri, umuti w'intungamubiri wa Hoagland wongewe ku isafuriya y'imbuto.

Spektrum y'urumuri rwera rwa LED

Ibipimo n'uburyo bwo gusarura

Urebye ko iyo uburebure bw'ibimera bugeze ku burebure bw'urumuri rw'izuba, ubikuremo. Byaciwe ku ya 22 Ugushyingo, 9 Ukuboza na 26 Ukuboza, uko bikurikirana, hamwe n'igihe cy'iminsi 17. Uburebure bw'ibishishwa bwari cm 2.5±0.5, kandi ibimera byatoranijwe mu myobo 3 mu gihe cyo gusarura, maze ibyatsi byasaruwe bipimwa kandi bikandikwa, kandi umusaruro kuri metero kare wabarwa muri formula (1). Umusaruro, W ni uburemere bushya bwa buri gishishwa cyaciwe.

Umusaruro = (W × 32) / 0.1512/1000 (kg / ㎡)

(Ubuso bw'isahani = 0.54 × 0.28 = 0.1512 ㎡) (1)

Ibisubizo n'isesengura

Ku bijyanye n'umusaruro mpuzandengo, umusaruro w'ibihingwa bibiri wari uw'igihingwa cya mbere > igihingwa cya gatatu > igihingwa cya kabiri, 24.7 g > 15.41 g > 12.35 g (ibinyampeke 7 / umwobo), 36.6 g > 19.72 g, uko bikurikirana. ＞16.98 g (udupira 14 / umwobo). Hari itandukaniro rinini hagati y'ubunini bw'ibihingwa bibiri mu musaruro w'igihingwa cya mbere, ariko nta tandukaniro rinini hagati y'igihingwa cya kabiri, icya gatatu n'umusaruro wose.

Ingaruka z'umuvuduko wo kubiba no gukata ibishyimbo ku musaruro w'ibyatsi by'ingano

Dukurikije gahunda zitandukanye zo gutema, ukwezi k'umusaruro kabarwa. Igihe kimwe cyo gutema ni iminsi 20; ingemwe ebyiri ni iminsi 37; naho ingemwe eshatu ni iminsi 54. Igipimo cyo gutera imbuto cy'ingemwe 7/umwobo cyari gifite umusaruro muto cyane, ni 5.23 kg/㎡ gusa. Igihe igipimo cyo gutera imbuto cyari ingemwe 14/umwobo, umusaruro w'ingemwe 3 wari 15.51 kg/㎡, wari hafi inshuro 3 z'umusaruro w'ingemwe 7/umwobo inshuro 1, kandi wari hejuru cyane ugereranije n'izindi nshuro zo gutema. Igihe cyo gukura cy'ingemwe eshatu cyari inshuro 2.7 z'umusaruro w'ingemwe imwe, ariko umusaruro wari hafi inshuro 2 z'umusaruro w'ingemwe imwe. Nta tandukaniro rigaragara mu musaruro ryabayeho ubwo igipimo cyo gutera imbuto cyari ingemwe 7/umwobo inshuro 3 n'ingemwe 14/umwobo inshuro 2, ariko itandukaniro ry'igihe cyo gukora hagati y'ubwo buryo bwombi ryari iminsi 17. Iyo igipimo cy’imbuto cyari ibinyampeke 14 ku mwobo waciwe rimwe, umusaruro ntiwari utandukanye cyane n’uw’ibinyampeke 7 ku mwobo waciwe rimwe cyangwa kabiri.

Umusaruro w'ibyatsi byaciwe inshuro 1-3 munsi y'ingano ebyiri z'imbuto

Mu musaruro, hagomba gushyirwaho umubare ukwiye w'amashelufu, uburebure bw'amashelufu, n'umuvuduko w'imbuto kugira ngo umusaruro wiyongere kuri buri gice, kandi guca ibiti ku gihe bigomba guhuzwa no gusuzuma ubuziranenge bw'imirire kugira ngo hakorwe ireme ry'umusaruro. Ikiguzi cy'ubukungu nk'imbuto, abakozi, n'ububiko bw'ibyatsi bishya nabyo bigomba kwitabwaho. Muri iki gihe, inganda z'ibyatsi nazo zihanganye n'ibibazo by'uburyo budatunganye bwo kuzenguruka ibicuruzwa no ku rwego rwo hasi rwo kubicuruza. Bishobora gukwirakwizwa gusa mu duce duto, ibyo bikaba bidafasha mu guhuza ubwatsi n'amatungo mu gihugu hose. Umusaruro w'inganda z'ibimera ntushobora gusa kugabanya uruziga rw'isarura ry'ibyatsi bya rye, kunoza igipimo cy'umusaruro kuri buri gice, no kugera ku mwaka w'ibyatsi bishya, ahubwo bishobora no kubaka inganda hakurikijwe ikwirakwizwa ry'ahantu n'urwego rw'inganda z'ubworozi, bigagabanya ikiguzi cy'ibikoresho.

Incamake

Muri make, birashoboka gukora ubwatsi bw'imyembe munsi y'urumuri rwa LED. Umusaruro w'ibinyampeke 7/umwobo n'ibinyampeke 14/umwobo byombi wari munini ugereranije n'uw'umusaruro wa mbere, bigaragaza ko wa mbere wagabanutse hanyuma ukiyongera. Umusaruro w'ibinyampeke bibiri wageze kuri 11.11 kg/㎡ na 15.51 kg/㎡ mu minsi 54. Kubwibyo, umusaruro w'ubwatsi bw'imyembe mu nganda z'ibimera ushobora gukoreshwa mu bucuruzi.
