  • Urea

    Urea

    ʻO Lemandou urea me kahi ʻike 46 kenetene hauota, kahi huahana mea hoʻomomona nitrogen paʻa. Hoʻohana ākea ʻo Urea i ka mahiʻai. ʻO ia ka ʻano maʻamau o ka mea hoʻomomona nitrogen i hoʻohana ʻia a puni ka honua. Ua manaʻo ʻia lākou he kumuwaiwai waiwai waiwai. Hana ʻia mai ka amonia a me ka carbon dioxide, ʻo ia ka nui o nā mea nitrogen kiʻekiʻe o kēlā me kēia mea hoʻomomona nitrogen paʻa. Ma ke ʻano he huahana granular, hiki ke hoʻopili pono ʻia i ka urea i ka lepo me ka hoʻohana ʻana i nā pono pālahalaha maʻamau. Ma waho o nā noi lepo, hiki ke hoʻohana pū ʻia nā mea urea fertilizers i ka momona a i ʻole me he noi foliar. Eia nō naʻe, ʻaʻole pono e hoʻohana i nā mea kanu urea i ka hoʻohaʻahaʻa i ka lepo, no ka mea e hemo koke ʻo urea mai ka ipu.

  • Ammonium Sulphate

    ʻO Ammonium Sulphate

    ʻO kahi mea hoʻomomona nitrogen maikaʻi (ʻike ʻia ma ke ʻano he lepo momona mea kūpono no ka lepo āpau a me nā mea kanu. Hiki iā ia ke hoʻoulu ikaika i nā lālā a me nā lau, hoʻomaikaʻi i ka maikaʻi o ka hua a me ka hua, a hoʻonui i ke kūpaʻa o nā hua i nā pōʻino. Hiki ke hoʻohana ʻia e like me ka momona momona, topdressing fertilizer a me nā mea kanu hua.

  • Magnesium Sulphate

    Makanekiuma Sulphate

    Hiki i ka MagnesiumSulphate ke hāʻawi i nā mea momona momona no nā mea kanu i hāʻawi i ka ulu ʻana o ka hua a hoʻonui i ka hopena, kōkua ia e hoʻokuʻu i ka lepo a hoʻomaikaʻi i ka maikaʻi o ka lepo.

  • Potassium Sulphate

    ʻO Potassium Sulphate

    ʻO ka potassium sulfate kahi paʻakai paʻakai ʻole me ka kemika kemika o K Ψ so ₄. ʻO ka maʻamau, ʻo ka ʻike o K 50% - 52%, a ʻo ka ʻike o S ma kahi o 18%. ʻO ka potassium sulfate maʻemaʻe ʻole he aniani kala ʻole, a melemele ka hapanui o ka helehelena potassium sulfate. ʻO ka potassium sulfate kahi maikaʻi o ka wai potassium i hoʻonā ʻia i ka wai ma muli o ka haʻahaʻa o ka hygroscopicity, ka liʻiliʻi liʻiliʻi, nā waiwai kino maikaʻi a me ka hoʻohana maʻalahi. ʻO ka potassium sulphate kūpono loa ia no nā mea kanu waiwai, e like me ka paka, ka hua waina, ka beet kō, ka mea kanu kī, potato, flax a me nā kumulāʻau hua like ʻole. ʻO ia ka mea maka nui no ka hana ʻana i ka nitrogen manuahi a ka paʻakai, ka phosphorous, ka potassium ternary compound fertilizer. ʻO ka potassium sulfate kahi mea kūlohelohe ʻole kemika, mea hoʻomomona waikawa physiological, i kūpono no nā ʻano like ʻole o ka lepo (me ka waiho ʻole i ka lepo i hoʻokahe ʻia) a me nā mea kanu. Ma hope o ka hoʻopili ʻia ʻana i ka lepo, hiki ke hoʻopili pono ʻia ka potona ion e nā mea kanu a lawe ʻia paha e nā colloids lepo. Ua hōʻike ʻia nā hopena e hiki ke hoʻopili ʻia ka potassium sulfate i nā mea kanu Cruciferae a me nā mea kanu ʻē aʻe e pono ai ka sulfur i ka lepo me ka hemahema sulfur.

  • Zinc Sulphate

    Zinc Sulphate

    Hiki ke hoʻohana ʻia e pale aku i nā maʻi o ka nursery lāʻau hua, a he mea hoʻomomona pū kekahi ia e hoʻopiha i ka zinc trace element fertilizer. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomomona kumu, mea hoʻomomona foliar, a pēlā aku. [6] ʻO ka kiniki kekahi o nā mea pono nui o ka nutrient no nā mea kanu. Maʻalahi ke ʻike ʻana i nā pua pua keʻokeʻo i ka maize ma muli o ka hemahema o ka zinc. Ke koʻikoʻi ka hemahema o ka zinc, e pau nā ulu ʻana a make a make paha. ʻOi aku no ka lepo one one a me nā mahinaʻai me ka waiwai nui o ka pH, pono e hoʻopili i ka zinc fertilizer e like me zinc sulfate. Loaʻa ka hoʻonui ʻana o ka zinc fertilizer i ka hopena o ka hoʻonui ʻana i ka hua. Hana hana hana: lawe i 0.04 ~ 0.06 kg zinc fertilizer, wai 1 kg, pale lole ʻana i 10 kg, ahu iho no 2 ~ 3 mau hola e lūlū ai. Ma mua o ka lūlū ʻana, hoʻopili ʻia ka zinc fertilizer i ka papa rhizosfer me 0.75-1kg / mu. Inā māmā ka lau o ka lau ma ke kahua seedling, hiki ke kāpī ʻia ka zinc fertilizer me 0.1kg / mu
