Oyi - Ndị mmeri Hardy: Letus anaghị atụ egwu oyi

Na griin haus oyi, obere okpomọkụ bụ isi ihe ịma aka maka ịkụ mkpụrụ letus. Letus "Winter Delight", site na ịmụba ogologo oge, nwere ezigbo mkpụrụ ndụ oyi na-eguzogide. N'ime griin haus na Northeast China, abalị - oge okpomọkụ na-ekpo ọkụ n'etiti 2 - 6 ℃ maka ụbọchị iri n'usoro. Ọ bụ ezie na ụdị letus dị iche iche kwụsịrị itolite, letus "Winter Delight" nọgidere na-egbuke egbuke na akwụkwọ ndụ akwụkwọ ndụ. Mkpụrụ ndụ akwụkwọ ya na-akwakọba nnukwu ihe antifreeze dị ka proline, nke na-ebelata ebe mmiri na-ekpo ọkụ nke sap cell, na-egbochi sel ndị ahụ site na obere okpomọkụ mebiri emebi. N'oge owuwe ihe ubi, mkpụrụ ya dị naanị ihe dịka 12% na-erughị nke ahụ n'okpuru okpomọkụ nkịtị, ebe mkpụrụ nke ụdị letus dị iche iche na-agbada site na 45% - 55%, na-egosi ọdịiche doro anya.

letus "Cold Emerald" nwekwara nnukwu oyi - nguzogide. A na-eji akwa wax dị mkpa kpuchie akwụkwọ ya gbara ọkpụrụkpụ n'elu.

N'ime griin haus dị na Hebei, n'oge oyi mgbe okpomọkụ na-agbanwekarị gburugburu 7 ℃, letus "Cold Emerald" tolitere akwụkwọ ọhụrụ ngwa ngwa, na-enwe kọmpat na osisi siri ike. Ọnụnọ ndụ ya dị 25% - 35% karịa nke ụdị letus nkịtị.

Kpakpando Hydroponic: Na-eme nke ọma na Ngwọta Nri

N'oge a, hydroponics na-aghọwanye ewu ewu na griin haus letus. Letus "Hydroponic Jade" nwere usoro mgbọrọgwụ siri ike na ikike dị ịtụnanya ime mgbanwe na gburugburu mmiri.

Ọ bụrụhaala na a na-achịkwa okpomọkụ n'etiti 18 - 22 ℃ na ngwọta edozi edozi nke ọma, enwere ike iweta ya n'ime ụbọchị 35. Na Chengfei Greenhouse, n'oge oyi, site na njikwa gburugburu ebe obibi nwere ọgụgụ isi, a na-akụ letus "Hydroponic Jade" n'ọtụtụ buru ibu. Otu ebe a na-akụ ihe ruru 1500 square mita, a na-edobekwa mkpụrụ n'otu ihe ọkụkụ na 9-10 tọn. letus a na-egbute nwere nnukwu akwụkwọ na-egbuke egbuke ma na-atọ ụtọ nke nwere ụtọ ụtọ nke a na-eto nke ukwuu.

Letus "Crystal Ice Leaf" bụkwa kpakpando na hydroponics. A na-ekpuchi akwụkwọ ya na kristal - sel vesicular doro anya, nke ọ bụghị nanị na-eme ka ọ mara mma ma na-abawanye mmiri ya - ikike nchekwa. Na gburugburu ebe obibi hydroponic, ọ nwere ike ịmegharị ngwa ngwa na mgbanwe nke nri na mmiri. N'ime obere ụlọ - ụdị griin haus hydroponic na Shanghai, a na-akụ mkpụrụ osisi 80 nke letus "Crystal Ice Leaf". Onye nwe ya nọchiri ihe ngwọta na-edozi ahụ n'oge ọ bụla kwa izu wee jiri igwe ikuku na-eme ka ikuku oxygen gbazere n'ime mmiri. letus toro ike.
