Hoʻokahi Super Phosphate i loko o ka Phosphate Fertilizers
ʻO Single Super Phosphate (SSP), ʻo ia ka mea kanu phosphatic kaulana loa ma hope o DAP no ka mea he 3 mau mea kanu mea kanu nui ʻo ia ʻo Phosphorus, Sulfur a me Calcium me nā ʻāpana o nā micro-nutrients he nui. Loaʻa ka SSP i ka ʻōiwi a hiki ke hāʻawi ʻia i ka manawa pōkole. He kumu maikaʻi loa ʻo SSP o ʻekolu mau mea kanu mea kanu. Hoʻopili ka mea P i ka lepo e like me nā mea hoʻoheheʻe hiki ke hoʻoheheʻe ʻia. ʻO ka loaʻa ʻana o ka P a me ka sulfur(S) ma SSP hiki ke lilo i mea waiwai agronomic kahi i nele ai kēia mau meaʻai ʻelua. Ma nā haʻawina agronomic kahi i hōʻike ʻia ai ʻoi aku ka maikaʻi o ka SSP ma mua o nā mea kanu P ʻē aʻe, ma muli o ka S a/a i ʻole Ca i loko. Ke loaʻa ma ka ʻāina, ua ʻike ʻo SSP i ka hoʻohana ākea ākea no ka hoʻomomona ʻana i nā wahi e pono ai ka P a me S. Ma ke kumu o P wale nō, ʻoi aku ka nui o ke kumukūʻai o SSP ma mua o nā mea momona ʻē aʻe, no laila ua emi ka kaulana.
ʻO Single Superphosphate (SSP) ʻo ia ka mea kanu mineral mua a alakaʻi i ka hoʻomohala ʻana i ka ʻoihana mea kanu mea kanu hou. ʻO kēia mea kanu ka mea hoʻomomona maʻamau i hoʻohana ʻia, akā ua hoʻololi nui nā mea kanu phosphorus(P) i ka SSP ma muli o kona haʻahaʻa P.
Hoʻohana nui ʻia e like me ka mea kanu mea kanu, basal a i ʻole nā mea kanu manure noi;
He kūpono no nā ʻano mea kanu āpau, ʻoi aku ka pili i ka lepo alkaline, ka lepo alkaline liʻiliʻi a me ka lepo kūlohelohe, ʻaʻole pono e hui pū ʻia me
lime, mea kanu lehu a me nā mea hoʻomomona kumu ʻē aʻe.
ʻAʻole hiki ke hoʻoikaika i ka ulu a me ka ulu ʻana o ka mea kanu, akā hiki ke hana i ka mea kanu i ke kūʻē ʻana i ka maʻi, ka maloʻo, ka wā mua, ka noho ʻana, ʻaʻole maʻalahi i ka pulupulu, ke kō, ke kō, ka palaoa i ka hopena nui e hoʻonui.
hana ʻana.
ʻO ka huahana ma ke ʻano he mea hoʻohui o ka calcium, phosphorus i ka hana ʻai.

ʻO Phosphate kekahi o nā huahana noi lalo o ka waika phosphoric, ʻoi aku ma mua o 30%. ʻO ia kekahi o nā mea maoli o nā meaʻai a pau. Ma ke ʻano he meaʻai koʻikoʻi a me ka mea hoʻohui hana, hoʻohana nui ʻia ka phosphate i ka hana ʻai. He waiwai nui ʻo Kina i ka phosphate a me nā huahana phosphate me ka pālākiō hana nui. Aia ma kahi o 100 mau ʻano a me nā kikoʻī o ka phosphate a me nā huahana phosphide, a ʻo Zongsheng ka mana hana ma kahi o 10 miliona mau tons. ʻO nā huahana nui he phosphoric acid, sodium tripolyphosphate, sodium hexametaphosphate, feed phosphate, phosphorus trichloride, phosphorus oxychloride, etc.
I kēia manawa, nāwaliwali ka noi no nā huahana phosphate lalo ma Kina. ʻO ka phosphate kuʻuna e like me ka sodium tripolyphosphate e hoʻoulu i ka pilikia o ka "eutrophication" i ka wai, e emi mālie ka ʻike o ka sodium tripolyphosphate i ka pauka holoi, a e hoʻololi iki kekahi mau ʻoihana i ka sodium tripolyphosphate me nā huahana ʻē aʻe, e hōʻemi ana i ka noi o nā ʻoihana o lalo. Ma ka ʻaoʻao ʻē aʻe, ʻo ka noi no nā huahana kemika phosphorus maikaʻi a kūikawā e like me ka medium and high-grade phosphoric acid a me ka phosphate (electronic grade and food grade), compound phosphate a me organic phosphate ua piʻi wikiwiki.
Hoʻopili: 25kg mea hoʻopuka maʻamau pūʻolo, ʻeke PP i ulana ʻia me ka liner PE
Ka mālama ʻana: E mālama i kahi anuanu, maloʻo a maikaʻi ka makani
