Ma ke kaiāulu mahiʻai, i ka wā e hoʻoilo ai ka hoʻoilo, lilo ʻo "nā ʻano letus no ka mahi ʻana i ka hale kōmaena i ka hoʻoilo" i huaʻōlelo hulina kaulana. Ma hope o nā mea a pau, ʻo wai ka mea makemake ʻole e hoʻopiha ʻia kā lākou hale ʻōmaʻomaʻo i nā mea ʻōmaʻomaʻo a hoʻohua mai i ka letus hou a palupalu i ke kau anuanu? I kēia lā, e ʻimi kākou i ka honua o ka mahiʻai letus hale hoʻoilo hoʻoilo a ʻike i nā ʻano ʻano hana maikaʻi loa.
Anu - Hardy Champions: Nā Lettuces Makaʻu ʻole i ke Anu
I nā hale ʻōmaʻomaʻo hoʻoilo, ʻo ka haʻahaʻa haʻahaʻa ka paʻakikī mua no ka mahi ʻana i ka letus. ʻO ka lettuce "Winter Delight", ma o ka hoʻoulu ʻana i ka wā lōʻihi, loaʻa kahi gene kūʻokoʻa maikaʻi loa. I loko o kahi hale ʻōmaʻomaʻo ma Northeast Kina, ua lele ka mahana o ka pō ma waena o 2 - 6 ℃ no nā lā he ʻumi. ʻOiai ua pau ka ulu ʻana o nā ʻano letus maʻamau, ua mau ka letus "Winter Delight" me nā lau ʻōmaʻomaʻo. ʻO kona mau lau lau e hōʻiliʻili i ka nui o nā mea antifreeze e like me ka proline, ka mea e hoʻohaʻahaʻa ai i ka pae maloʻo o ke kohu o ke kelepona, e pale ana i ka pōʻino o nā cell e nā wela haʻahaʻa. I ka hōʻiliʻili ʻana, ʻoi aku ka liʻiliʻi o kāna hua ma kahi o 12% ma lalo o nā mahana maʻamau, ʻoiai ʻo ka hua o nā ʻano lettuce maʻamau i hāʻule i ka 45% - 55%, e hōʻike ana i kahi ākea ākea.
ʻO ka lettuce "Cold Emerald" he kūʻokoʻa kūʻokoʻa. Ua uhi ʻia kona mau lau mānoanoa me kahi ʻāpana waxy lahilahi ma ka ʻili. ʻAʻole hoʻemi wale kēia papa waxy i ka hoʻoheheʻe ʻana o ka wai, mālama i ka mea kanu "moist", akā hana pū nō hoʻi e like me ka insulation, e pale ana i ke ea anuanu mai ka hoʻouka ʻana i nā ʻiʻo o loko. I loko o ka hale ʻōmaʻomaʻo ma Hebei, i ka wā hoʻoilo ke piʻi pinepine ka mahana ma kahi o 7 ℃, ua ulu wikiwiki ka letus "Cold Emerald" i nā lau hou, me kahi mea kanu paʻa a paʻa. ʻO 25% - 35% kiʻekiʻe kona ola ola ma mua o nā ʻano lettuce maʻamau.
Nā Hōkū Hydroponic: Ke holomua nei i loko o nā meaʻai meaʻai
I kēia mau lā, ke ulu nui nei ka hydroponics i ka mahi ʻana i ka lettuce greenhouse. ʻO ka lettuce "Hydroponic Jade" kahi ʻōnaehana aʻa i hoʻomohala nui ʻia a me ka hiki ke hoʻololi i ke ʻano wai. I ka manawa i hoʻokomo ʻia ai i loko o ka ʻōnaehana hydroponic, pālahalaha koke kona mau aʻa, e hana ana i kahi "pūnaewele absorption nutrient" ikaika e hiki ke lawe pono i nā meaʻai nui e like me ka nitrogen, phosphorus, a me ka potassium i loko o ka hopena nutrient. ʻOiai ka lōʻihi o ka mālama ʻia ʻana o ka mahana ma waena o 18 - 22 ℃ a me ka hoʻohālikelike pono ʻana o ka hopena nutrient, hiki ke ʻohi ʻia ma kahi o 35 mau lā. Ma Chengfei Greenhouse, i ka hoʻoilo, ma o ka hoʻomalu kaiapuni naʻauao, kanu ʻia ka lettuce "Hydroponic Jade" ma ke ʻano nui. Hoʻokahi kahi kanu i hiki i 1500 mau mika square, a mālama mau ʻia ka hua i kēlā me kēia mea kanu ma 9 - 10 tons. ʻO ka letus i hōʻiliʻili ʻia he lau nui, crispy, a me ka momona me ka ʻono ʻono i mahalo nui ʻia.
ʻO ka letus "Crystal Ice Leaf" kekahi hōkū i ka hydroponics. Ua uhi ʻia kona mau lau me nā ʻeleʻele vesicular akaka, ʻaʻole wale ia e nani ai akā e hoʻonui i kona wai - hiki ke mālama. I loko o ka hydroponic environment, hiki iā ia ke hoʻololi maʻalahi i nā loli i nā meaʻai a me ka wai. Ma kahi hale liʻiliʻi - style hydroponic greenhouse ma Shanghai, 80 mau mea kanu o "Crystal Ice Leaf" lettuce i kanu ʻia. Ua hoʻololi ka mea nona ka meaʻai i ka manawa i kēlā me kēia pule a hoʻohana i ka aerator e hōʻoia i ka lawa o ka oxygen dissolved i ka wai. Ua ulu ikaika ka letus. I ka ʻohi ʻana, ua hiki ke kaumaha o kēlā me kēia mea kanu ma kahi o 320 grams, me nā lau plump i waiwai i nā minerala like ʻole a me nā huaora.
Maʻi - Nā Heroes Kū'ē: Pale maʻalahi i nā maʻi
Nā hale ʻōmaʻomaʻoHoʻopili ʻia me ka haʻahaʻa kiʻekiʻe, he "paradaiso" no nā pathogens. Eia naʻe, ʻaʻole makaʻu ka lettuce "Disease - Resistant Star". Loaʻa iā ia nā metabolites lua i loko o kāna mea kanu, e like me nā phytoalexins a me nā pūhui phenolic. Ke hoʻokomo ʻia nā pathogens, hoʻōla koke ia i kāna hana pale. I loko o kahi hale ʻōmaʻomaʻo ma kahakai o Zhejiang, kahi i kiʻekiʻe ai ka haʻahaʻa o ka makahiki a puni, ʻo ka ulu ʻana o ka maʻi maʻamau i nā ʻano lettuce maʻamau he kiʻekiʻe e like me 55% - 65%. Ma hope o ke kanu ʻana i ka lettuce "Disease - Resistant Star", ua hāʻule ka hopena i 8% - 12%. I ke alo o nā pathogens downy mildew, nā phytoalexins i loko o ka "Disease - Resistant Star" lettuce hiki ke kāohi i ka germination o nā spores pathogen a me ka ulu ʻana o ka hyphae, e pale ana i nā pathogens mai ka noho ʻana a hoʻolaha i ka mea kanu. Hoʻemi nui ʻia ka hoʻohana ʻana i nā lāʻau pesticides, a ʻoi aku ka ʻōmaʻomaʻo o ka letus i hana ʻia.
