Diammonium phosphate: hoʻohana a me nā waiwai
Ke hoʻolauna nei i kā mākou Diammonium Phosphate (DAP) kiʻekiʻe, he mea hoʻomomona nui no ka ulu ʻana a me ka ulu ʻana o nā ʻano mea kanu. He mea hoʻoheheʻe ʻia ʻo DAP i maʻalahi e hoʻohana a hōʻoia i ka liʻiliʻi o nā mea paʻa e waiho ʻia ma hope o ka hemo ʻana. He mea kūpono kēia waiwai no ka hoʻokō ʻana i nā pono o ka nitrogen a me ka phosphorus o nā mea kanu like ʻole.
Diammonium phosphateHe kumu waiwai ia o ka nitrogen a me ka phosphorus, ʻelua mau meaʻai koʻikoʻi no ka ulu olakino olakino. He mea maikaʻi loa ia no ka hoʻoulu ʻana i ke aʻa, hoʻomaikaʻi i ka pua a me ka hoʻohua ʻana, a me ka hoʻonui ʻana i nā hua hua āpau. Hiki i ka DAP ke hoʻoheheʻe wai maikaʻi loa a maʻalahi hoʻi e hoʻopili ʻia e nā mea kanu, e hōʻoia ana i ka lawe ʻana a me ka hoʻohana ʻana i nā meaʻai.
Hana ʻia kā mākou DAP i nā kūlana kiʻekiʻe loa, e hōʻoiaʻiʻo ana i kona maʻemaʻe a me ka pono. Mālama nui mākou i ke kaʻina hana e hōʻoia i ka hoʻokō ʻana o kā mākou huahana i nā pono o ka mahiʻai hou.

ʻO ka Diammonium phosphate he paʻakai keʻokeʻo keʻokeʻo me ka solubility kiʻekiʻe i ka wai. He hygroscopic, ʻo ia hoʻi, hiki ke hoʻopaʻa maʻalahi i ka makū mai ka lewa. He mea nui kēia waiwai i ka mālama ʻana iā DAP i kahi maloʻo e pale ai i ka clumping a mālama i kona pono.
ʻO kekahi o nā pōmaikaʻi nui o DAP ʻo ia ka mea momona kiʻekiʻe, e hāʻawi ana i nā mea kanu me ka phosphorus a me ka nitrogen. He mea maʻalahi a hiki ke hoʻohana ʻia e like me ke kumu a me ka lole luna. Hoʻohui, kōkua ka pH haʻahaʻa o DAP e hōʻemi i ka alkalinity lepo a hoʻomaikaʻi i ka lawe ʻana o nā mea kanu i nā meaʻai.
ʻOiai hāʻawi ʻo DAP i nā pono he nui, he mea nui nō hoʻi e noʻonoʻo i kāna mau drawbacks. Hoʻohana nui ʻia odiammonium phosphatehiki ke hoʻopilikia i nā meaʻai o ka lepo a pōʻino paha i ke kaiapuni. Eia kekahi, pono kona ʻano hygroscopic i ka mālama pono ʻana a me ka mālama ʻana e mālama i kona maikaʻi.
- Ke hoʻomau ʻia nā pae kiʻekiʻe o ka phosphorus i hui pū ʻia me ka nitrogen: e laʻa no ka ulu ʻana o ke aʻa i ka wā mua o ka wā ulu;
- Hoʻohana ʻia no ka hānai ʻana i nā lau, fertigation a ma ke ʻano he mea hoʻohui i ka NPK;-He kumu kūpono loa o ka phosphorus a me ka nitrogen;
- Kūpono me ka hapa nui o nā mea hoʻoheheʻe wai.
ʻO ka Diammonium phosphate (DAP) he paʻakai paʻakai ʻole i hoʻohana nui ʻia me ke ʻano kemika (NH4)2HPO4. Ma muli o kāna hana kūikawā a me kāna mau hiʻohiʻona, kaulana ia no ka nui o nā noi i nā ʻoihana like ʻole. ʻO DAP he aniani monoclinic ʻaʻole waihoʻoluʻu a i ʻole ka pauka keʻokeʻo. Hiki ke hoʻoheheʻe ʻia i ka wai akā ʻaʻole i ka waiʻona, e lilo ia i mea maʻalahi a maikaʻi hoʻi no nā hoʻohana he nui.
Hoʻohana nui ʻia ka Diammonium phosphate i ka kemika analytical, ka hoʻoponopono meaʻai, ka mahiʻai a me ka mahiʻai holoholona. ʻO kāna ʻano nui o ka hoʻohana ʻana he mea pono ʻole ia i nā ʻano hana ʻoihana a me nā ʻoihana.
Ma ke kahua o ka kemika analytical, hoʻohana ʻia ka diammonium phosphate ma ke ʻano he reagent i nā kaʻina hana analytical. ʻO kona hiki ke hoʻoheheʻe ʻia i loko o ka wai a me ka launa pū ʻana me nā mea ʻē aʻe e kūpono ia no ka nānā ʻana a me nā hoʻokolohua kemika. ʻO ka maʻemaʻe a me ka paʻa ʻana o ka pūhui e lilo ia i mea hilinaʻi i nā hoʻonohonoho hoʻokolohua.
I loko o ka ʻoihana hana meaʻai, he kuleana koʻikoʻi ka DAP ma ke ʻano he mea hoʻohui meaʻai a me ka meaʻai meaʻai. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he mea hū i ka kuke ʻana, e kōkua ana i ka hana ʻana i ka carbon dioxide, kahi e hana ai i kahi ʻano māmā, ea i loko o nā mea i kālua ʻia. Eia kekahi, hoʻohana ʻia ka diammonium phosphate ma ke ʻano he kumu o ka nitrogen a me ka phosphorus i ka hoʻoikaika ʻana i ka meaʻai, e kōkua ana i ka hoʻonui ʻana i ka waiwai o nā meaʻai i hoʻoponopono ʻia.
ʻO ka mahiʻai a me ka mahiʻai holoholona ka pōmaikaʻi nui mai ka hoʻohana ʻana idiammonium phosphate. Me he mea hoomomona la,DAPhāʻawi i nā meaʻai pono i nā mea kanu, hoʻoikaika i ka ulu maikaʻi a hoʻonui i nā hua hua. ʻO kona solubility kiʻekiʻe e hōʻoia i ka lawe pono ʻana i nā mea kanu e nā mea kanu, e lilo ia i koho kūpono no nā noi mahiʻai. Hoʻohui ʻia, hoʻohana ʻia ʻo DAP i nā ʻano meaʻai holoholona e hoʻomaikaʻi i ka ʻai meaʻai a kākoʻo i ke olakino a me ka maikaʻi o nā holoholona.
ʻO kekahi o nā ʻano kaulana o ka diammonium phosphate he DAP pellets, e hāʻawi ana i ka maʻalahi o ka lawelawe ʻana a me ka hoʻohana ʻana i nā ʻano hana mahiʻai. Hāʻawi nā pellets DAP i ka hoʻokuʻu mau ʻana i nā meaʻai, e kūpono ana iā lākou no ka hoʻohana ʻana i nā papahana fertilization no nā ʻano mea kanu.
I ka hōʻuluʻuluʻana, he mea waiwai nui ka diammonium phosphate me nā noi he nui i nā ʻoihana like ʻole. ʻO kona hoʻoheheʻe ʻana, kūpono a me ka meaʻai meaʻai he mea nui ia i ka kemika analytical, ka hana ʻai, ka mahiʻai a me ka mahiʻai holoholona. Inā ma ke ʻano o nā kristal, pauka a i ʻole granules, noho mau ʻo DAP i mea koʻikoʻi e kōkua i ka holomua a me ka pono o nā ʻano hana a me nā huahana.

Q1. He kūpono anei ka diammonium phosphate no nā ʻano mea kanu āpau?
Ua kūpono ʻo DAP no nā ʻano mea kanu like ʻole, me nā mea e koi ana i ka nitrogen-neutral phosphorus.
Q2. Pehea e hoʻohana ai i ka diammonium phosphate?
Hiki ke hoʻohana ʻia ʻo DAP e nā ʻano ʻano like ʻole, me ka hoʻolaha ʻana, ka ʻili ʻana a me ka fertigation, ma muli o nā koi kikoʻī o ka mea kanu a me ka lepo.
Q3. Hiki ke hoʻohana ʻia ka diammonium phosphate i ka mahiʻai organik?
ʻOiai ʻaʻole i manaʻo ʻia ʻo DAP he mea kanu kūlohelohe, hoʻohana maʻamau ia i nā hana mahiʻai maʻamau e hāʻawi i nā meaʻai pono i nā mea kanu.
