Ka hoomalu ana i ka fertilization

[Hoʻololi i ka nui o ka pua]I mea e lanakila ai i ka makahiki nui a me ka liʻiliʻi o ka māla ʻāpala, e pīpī i ka 0.5% urea aqueous solution ma ka lau lau ma 5-6 mau pule ma hope o ka pua ʻana (ʻo ka wā koʻikoʻi o ka ʻokoʻa ʻana o ka pua apple, lohi a pau ka ulu ʻana o nā wana hou. , a me ka naikokene maʻiʻo o nā lau e hōʻike ana i ke au i lalo), pulupulu 'elua i ka succession, hiki ke hoonui i ka naikokene maʻiʻo o nā lau, e hoʻokēʻai i ka ulu ana o ka hou opuu, keʻakeʻa pua opuu 'okoʻa, a me ka nui pua o ka makahiki nui kūpono.

[Ka pua a me ka ʻili hua]ʻOi aku ka maʻalahi o nā ʻāpana pua Peach i ka urea, akā ua lohi ka hopena, no laila, ʻo ka peach haole me ka hoʻāʻo ʻana i ka urea, nā hopena e hōʻike ana i ka peach a me ka nectarine pua a me nā hua thinning, pono i ka manaʻo nui (7.4%) e hōʻike i nā hopena maikaʻi. ʻO ka manaʻo he 8% -12%, 1-2 mau pule ma hope o ka pīpī ʻana, e hoʻokō i ke kumu o ka pua a me nā hua thinning.

[Hana hua laiki]I ka ʻenehana hana hua laiki hybrid, i mea e hoʻomaikaʻi ai i ka nui o ka outcross rate o nā mākua, i mea e hoʻonui ai i ka nui o ka hua o ka laiki hybrid a i ʻole ka nui o ka momona o nā laina sterile, ua lawe ʻia ka hoʻokolohua me ka urea ma kahi o gibberellin, a me ka hoʻohana ʻana. o ka 1.5% a hiki i ka 2% urea i ka wā hāpai hāpai a me ka pae pepeiao mua (20% koho pepeiao), ua like ka hopena fertility me ka gibberellin, a ʻaʻole ia i hoʻonui i ke kiʻekiʻe o ka mea kanu.

[Ka hoʻomalu pest]Me ka urea, ka pauka holoi, ka wai 4: 1: 400, ma hope o ka hui ʻana, hiki ke pale i nā kumulāʻau hua, nā mea kanu, nā aphids pulupulu, nā ʻulaʻula ʻulaʻula, nā iniseti kāpeti a me nā mea ʻē aʻe, ka hopena insecticidal ma mua o 90%.[Urea iron fertilizer] Hoʻokumu ka Urea i ka hao chelated me Fe2+ ma ke ʻano paʻakikī.He haʻahaʻa ke kumu kūʻai haʻahaʻa a he hopena maikaʻi kēia ʻano mea hoʻomomona hao i ka pale ʻana i ka nele o ka hao a me ka poho ʻōmaʻomaʻo.ʻOi aku ka maikaʻi o ka hopena o ka chlorosis ma mua o ka 0.3% ferrous sulfate.

Ka paʻi lole a me ka waihoʻoluʻu

① Hiki ke hoʻohana ʻia e like me ka nui o ka melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, caffeine, VAT brown BR, phthalocyanine B, phthalocyanine Bx, monosodium glutamate a me nā huahana ʻē aʻe.

② He hopena hoʻomālamalama ia i ka polishing kemika o ke kila a me ke kila kila, a hoʻohana ʻia e like me ka corrosion inhibitor i ka pickling metala, a hoʻohana ʻia hoʻi i ka hoʻomākaukau ʻana i ka wai hoʻōla palladium.

③ Ma ka ʻoihana, hoʻohana ʻia ia ma ke ʻano he mea maka no ka hana ʻana i nā resins urea-formaldehyde, polyurethanes a me melamine-formaldehyde resins.

④ ʻO ka mea hoʻemi koho koho no ka denitrification o ke kinoea hoʻopau ahi, a me ka urea automotive, i haku ʻia he 32.5% kiʻekiʻe-maʻemaʻe urea a me 67.5% wai deionized.

⑤ No ka hoʻokaʻawale ʻana i ka paraffin wax (no ka mea hiki i ka urea ke hana i nā clathrates), nā mea refractory, nā ʻāpana o ka ʻenekini palekana kaiapuni, nā ʻāpana o nā huahana keʻokeʻo niho, nā mea kanu kemika, nā mea kōkua koʻikoʻi no ke kala a me ka paʻi.

⑥ ʻO ka ʻoihana textile kahi mea hoʻoheheʻe dye maikaʻi loa / hygroscopic agent / viscose fiber expanding agent, resin finishing agent, he nui nā mea hoʻohana.Hoʻohālikelike i nā waiwai hygroscopic o ka urea me nā mea hygroscopic ʻē aʻe i ka ʻoihana textile: ratio i kona kaumaha ponoʻī.

Papa hoʻomaʻemaʻe (mea hoʻomaʻemaʻe)

Hoʻohana ka Dermatology i kekahi mau mea i loaʻa i ka urea e hoʻonui i ka makū o ka ʻili.Aia ka 40% urea i loko o ka lole pani i hoʻohana ʻia no nā kui i wehe ʻole ʻia.ʻO ka Urea kahi mea hoʻomaʻemaʻe maikaʻi, aia i loko o ka cuticle o ka ʻili, ʻo ia ka mea hoʻomaʻemaʻe kūlohelohe o ka ʻili NMF mea nui.
