ʻO ke kuleana o ka diammonium phosphate ʻO ke ʻano kemika o diammonium phosphate he alkaline ia, no laila pili ia i ka mea hoʻomomona alkaline. ʻO Diammonium phosphate kahi nitrogen wikiwiki wikiwiki kiʻekiʻe a me nā mea momona momona phosphorus me ka phosphore e like me ke kumu nui. Kūpono ia no ka hapa nui o nā mea kanu a kūpono hoʻi no ka hoʻohana ʻana i nā lepo like ʻole. Loaʻa iā ia he ākea ākea o nā noi a hiki ke hoʻohana ʻia ma ke ʻano he fertilizer base a i ʻole topdressing. hiki
Noi o diammonium phosphate hiki ke hoʻohana ʻia ka Diammonium phosphate e hoʻohua i nā ʻano ʻano lepo ma nā māla paddy a me nā māla maloʻo. Kūpono ia no ka nui o nā mea kanu e like me ka laiki, ka palaoa, ka palaoa, kaʻuala, ka pī, ka pue, a me nā pī. Kūpono loa ia no nā mea kanu e koi ana i ka hydrogen a me ka phosphor e like me ke kō a me nā pahu wai. Hiki ke hoʻohana ʻia ka diammonium phosphate me ka amonium bicarbonate, urea, ammonium chloride, potassium chloride, amonium nitrate a me nā mea hoʻomomona. Hōʻalo i ka noi huikau me nā waikawa acidic e like me ka ammonium sulfate a me ka superphosphate. Maikaʻi loa ka hopena ma hope o ka hoʻohana. Paipai i ka ulu ʻana o nā mea kanu.
Pehea e hoʻohana ai i ka diammonium phosphate
1. Ua hōʻoia ka hoʻomaʻamaʻa hiki ke hoʻohana ʻia ka diammonium phosphate e hoʻomomona i nā ʻano lepo like ʻole ma nā māla paddy a me ka ʻāina maloʻo, kūpono no ka nui o nā mea kanu e like me ka laiki, palaoa, kulina, ʻuala, peanut, rape, peanut, a pēlā aku. Kūpono loa no koi aku ʻo hydrogen-phosphorus i nā mea kanu e like me ke kō a me ka chestnut wai.
2. Hiki ke hoʻohana i ka diammonium phosphate me ka amonium bicarbonate, urea, ammonium chloride, potassium chloride, amonium nitrate a me nā mea hoʻomomona ʻē aʻe. Hōʻalo i ka noi huikau me nā waikawa acidic e like me ka ammonium sulfate a me ka superphosphate.
3. Hōʻike nā hoʻokolohua i ka diammonium phosphate i hui pū ʻia me nā nitrogen a me nā potassium potassium (ʻaʻole pono e hoʻohana ʻia nā mea momona i loaʻa i ka chlorine no nā mea kanu ʻaʻohe chlorine) kūpono no ka noi ʻana i ka basal fertilizer, me kahi ana o 225 ～ 300kg / h㎡; noi i ka māla paddy: Ma hope o ka hoʻohuli ʻana i ka palau, hoʻopili iā ia i ka papa wai papau; Noi ʻāina maloʻo: noi hohonu i ka wā o ka palau ʻana a me ka hoʻohui ʻana, ka hoʻohuihui ʻana i ka lepo momona. Hoʻohui i ka diammonium phosphate a decomposed organic fertilizer me ka pH kūlike ʻole a hoʻopili ma hope o ka composting, pono ka mea momona. Ke hana ʻana i ka mea kanu hua, pono e hoʻopili ʻia i 1 mau lā ma mua o ka lūlū ʻana, he 100-150kg / h㎡ ke ana, a ua hui like ʻia ka lepo momona e pale pono i ka hoʻopili pololei ʻana ma waena o nā hua a me ka mea hoʻomomona.
4. No ka hoʻoulu ʻana me ka wai aqueous solution o diammonium phosphate, ka diammonium phosphate (nitrogen a me ka potassium fertilizer ma muli o ka ʻano o ka mea kanu) e hoʻoheheʻe ʻia i ka wai ma ka lakio o 1: 5 ma ke ana wela o ka lumi ma kahi e kokoke ana i ka pūnaewele hoʻouluulu 1 a 2 mau lā ma mua o ka momona. Ma hope o ka hoʻoheheʻe ʻana, e lawe i ka wai momona a hoʻowali iā ia me ka wai ma 1: 25-30, a i ʻole hoʻohana i ka biogas wai mea hoʻomomona e hoʻoheheʻe, a ʻo ka nui o ka wai momona i 60-80 mau manawa. E māmā ka hoʻouluulu ʻana i ka mahele seedling o ka hua a i ʻole ke maloʻo ka lepo; hiki ke hoʻonui kūpono ʻia ka hoʻouluulu ʻana i ka wā kanu mākua a pulu ka lepo.
ʻO nā contraindications no ka hoʻohana ʻana o diammonium phosphate Diammonium phosphate i loko o nā ions phosphate hou. Ma hope o ka hoʻoulu ʻana i nā mea kanu, e hoʻonui ia i ka acidity o ka lepo ma ka lepo acidic, i hiki ke hoʻololi i ka ulu ʻana o nā mea kanu. E mālama pono ʻole e hoʻohana iā ia ma ke ʻano he ʻaʻahu luna. E hohola i ka phammate diammonium granular ma ka ʻili, ʻaʻole e komo ke aʻa aʻa iā ia, a e nalowale ka hopena mea hoʻomomona. Hōʻalo i ka hui pū ʻana me nā mea momona acidic, e like me ka ammonium sulfate, superphosphate, a me nā mea ʻē aʻe, ʻoi aku ka acidic a me ka hopena o ka hopena.
