ʻO Triple superphosphate (TSP) kekahi o nā mea hoʻohiwahiwa kiʻekiʻe ʻo P fertilizers i hoʻohana ākea ʻia i ka kenekulia 20. ʻO ka ʻenehana, ʻike ʻia ia ma ke ʻano he calcium dihydrogen phosphate a me monocalcium phosphate, [Ca (H2PO4) 2 .H2O]. He kumuwaiwai P maikaʻi loa ia, akā ua hōʻole kāna hoʻohana ʻana ma muli o ka lilo ʻana o nā mea kanu P i mea makemake nui ʻia.

He maʻalahi ka manaʻo o ka hana TSP. Hana pinepine ʻia ʻo TSP non-granular e ka hoʻololi ʻana i ka pōhaku phosphate lepo finely me ka waikawa phosphoric wai i loko o kahi kāwili ʻano cone. Hana like ʻia ʻo Granular TSP, akā ua kāpīpī ʻia ka slurry hopena ma ke ʻano he uhi no nā huna liʻiliʻi e kūkulu i nā granula o ka nui i makemake ʻia. ʻAe ʻia ka huahana mai nā hana hana ʻelua e hoʻōla no nā pule he nui e like me ka lohi o ka hoʻopau ʻana o nā hopena kemika. E loli iki ke kemika a me ke kaʻina o ka hopena ma muli o nā waiwai o ka pōhaku phosphate.
ʻO Triple superphosphate i loko o ka granular (i hōʻike ʻia) a me nā ʻano granular ʻole.
Hoʻohana Mahiʻai
He mau pono agronomic ʻo TSP i lilo ia i kumu punahele no P no nā makahiki he nui. Loaʻa iā ia ka ʻike P kiʻekiʻe loa o nā mea hoʻomomona maloʻo ʻaʻole i loaʻa iā N. Ma kahi o 90% o ka nui o ka P ma TSP hiki ke hoʻoheheʻe ʻia ka wai, no laila hiki ke loaʻa maʻalahi no ka lawe ʻana o nā mea kanu. I ka hoʻoheheʻe ʻana o ka lepo i ka granule, lilo ka hopena o ka lepo i hoʻohui ʻia i acidic. Loaʻa iā TSP he 15% calcium (Ca), e hāʻawi ana i kahi mea kanu mea kanu hou.
Hoʻohana nui ʻia ʻo TSP i nā hanana kahi e hui pū ʻia ai kekahi mau mea momona paʻa no ka hoʻolele ʻana i ka papa o ka lepo a i ʻole no ka noi ʻana i kahi pēpili paʻa ma lalo o ka ʻili. Makemake pū ʻia ia no ka hoʻoulu ʻana i nā mea kanu leguminous, e like me ka alfalfa a i ʻole nā ​​pi, kahi e pono ʻole ai kahi hoʻonui N no ka hoʻopiha ʻana i nā hanana N biological.

Nā Hana Hoʻokele
Ua hōʻole ka kaulana o TSP no ka mea ʻo ka huina waiwai momona (N + P2O5) ʻoi aku ka haʻahaʻa ma mua o nā momona momona amonium e like me monoammonium phosphate, a ma ka hoʻohālikelike he 11% N a me 52% P2O5. Hiki ke ʻoi aku ke kiʻekiʻe o nā kumukūʻai o ka hana ʻana i ka TSP ma mua o nā phosphates ammonium, e hoʻoliʻiliʻi maikaʻi ʻole ana i nā ʻoihana no TSP i kekahi mau hanana.
Pono e mālama ʻia nā mea hoʻomomona P a pau i mea e pohō ai i ka holo ʻana o ka wai ma luna o nā kula. Hiki ke hāʻawi i ka lilo o ka phosphore mai ka ʻāina mahiʻai i kahi wai e pili kokoke ana i ka hoʻonāukiuki ʻole i ka ulu ʻana o ka limu. Hiki i nā hana hoʻokele kūpono kūpono ke hōʻemi i kēia makaʻu.
Na Hana Mahiai Ole
ʻO ka monocalcium phosphate kahi mea nui i ka pauka pauka. Hana ka acidic monocalcium phosphate me kahi mea alkaline e hana i ka carbon dioxide, ka mea hū no nā huahana i hoʻomoʻa ʻia. Hoʻohui pinepine ʻia ʻo Monocalcium phosphate i nā papaʻai holoholona ma ke ʻano he mea hoʻohui mineral nui o nā phosphate a me Ca.
