Izivundisi Ezihlanganisiwe ze-NPK

Lo manyolo we-NPK 12 11 18 ohlanganisiwe unesilinganiso sesayensi se-nitrogen, i-phosphorus kanye ne-potassium, kanye nezakhamzimba ezilinganiselayo neziphelele. Unganikeza amandla ngokunembile ezitshalweni kuzo zonke izigaba zokukhula, ukhuthaze ukukhula kwezimpande kanye nokukhula kwezithombo, futhi usize ekuqhakazeni nasekutheleni izithelo. Umphumela womanyolo uhlala isikhathi eside futhi uzinzile.

I-NPK 11-22-16 iyisichumisi esicebile nge-phosphorus esakhiwe, esine-nitrogen engu-11%, i-phosphorus engu-22%, kanye ne-potassium engu-16%, ithuthukisa ukukhula kwezimpande, ukuqala kwezimbali, kanye nokwakheka kwezithelo zakuqala, ilungele izitshalo ezizwela i-phosphorus kanye nokulungiswa kwenhlabathi.

Izakhi eziyinhloko zomanyolo we-NPK 30-10-10 granular zihlanganisa i-nitrogen (N ≥ 30%), i-phosphorus (P2O5 ≥ 10%), i-potassium (K2O ≥ 10%), kanye nezinto ezincane ezifana ne-magnesium, i-zinc, njll. zingangezwa. Lo manyolo ufanelekela izitshalo ezahlukahlukene futhi unganikeza i-nitrogen, i-phosphorus, i-potassium, kanye nezinto ezincane ezidingwa izitshalo, ukhuthaze ukukhula kwezitshalo, futhi uthuthukise isivuno kanye nekhwalithi.

Umanyolo ohlanganisiwe 12 6 22 umanyolo we-potassium ophezulu one-nitrogen engu-12%, i-phosphorus engu-6%, kanye ne-potassium engu-22%, kanye nokuqukethwe kwezakhamzimba okungu-40%. Lo manyolo ohlanganisiwe ufanelekela izitshalo ezahlukahlukene futhi unganikeza izakhamzimba ezahlukene ezidingekayo ekukhuleni kwezitshalo.

Umanyolo we-NPK 17-17-17 ohlanganisiwe uwumanyolo wesilinganiso esilinganiselayo, lapho okuqukethwe kwezakhamzimba ezintathu ezibalulekile, i-nitrogen (N), i-phosphorus (P2 O5), kanye ne-potassium (K2O), kungu-17%. Lesi silinganiso sinikeza umanyolo izinzuzo ezibalulekile emkhakheni wezolimo.

I-NPK 16-20 iyisichumisi esihlanganisiwe esine-nitrogen phosphorus potassium ratio engu-16-20-0, efanelekile ekukhuleni kwezitshalo ezahlukahlukene. Izici zayo ziwukuqukethwe kwe-nitrogen okungu-16%, okuqukethwe kwe-phosphorus okungu-20%, okuqukethwe kwe-potassium okungu-0%, kanye nokuqukethwe kwezakhamzimba okuphelele okungu-≥ 36%

I-NPK 15-5-20 iqukethe izakhi ezintathu eziyinhloko zezakhamzimba, i-nitrogen engu-15%, i-phosphorus engu-5% kanye ne-potassium engu-20%. Lesi silinganiso sifanelekela izidingo zezitshalo ezahlukahlukene ezigabeni ezahlukene zokukhula. Ayikwazi nje ukuhlangabezana nesidingo sesitshalo se-nitrogen esigabeni sokuqala sokukhula futhi ikhuthaze ukukhula kwamagatsha namaqabunga, kodwa futhi ihlinzeka nge-phosphorus ne-potassium eyanele yesitshalo esigabeni sokugcina, okuwusizo ekuhlukaniseni amahlumela ezimbali, ekukhuleni kwezithelo nasekuthuthukiseni ukumelana nokucindezeleka kwesitshalo.

Isitoreji:

1. Igcinwe endaweni eyomile futhi enomoya.

2. Hlala kude nomswakama kanye nokukhanya kwelanga okuqondile.

3. Ngesikhathi esifanayo, kufanele ivikelwe ekudliweni yizimpuku nezinambuzane ukuze kugwenywe ukuthinta ikhwalithi kanye nomphumela wokusetshenziswa komanyolo.

Umanyolo ohlanganisiwe 15-15-15 umanyolo olinganiselayo oqukethe i-nitrogen engu-15%, i-phosphorus engu-15%, kanye ne-potassium engu-15%, kanye nokuqukethwe kwezakhamzimba okungu-45%. Lo manyolo ohlanganisiwe ufanelekela izitshalo zasensimini futhi unganikeza izakhamzimba ezahlukahlukene ezidingekayo ekukhuleni kwezitshalo.

Isitoreji:

1. Umanyolo we-NPK 15-15-15 kufanele ugcinwe endaweni eyomile futhi enomoya omuhle, ugweme ukuthintana nomswakama namanzi ukuvimbela ukunamathela kanye nokunciphisa ukusebenza kahle komanyolo.

2. Uma igcinwa, kufanele igcinwe kude nokukhanya kwelanga okuqondile ukuvimbela ukubola nokulahlekelwa yizingxenye ezisebenzayo kumanyolo.

3. Kufanele kuthathwe izinyathelo zokuvimbela izinambuzane namagundane ngesikhathi sokugcina ukuze kuvinjelwe umonakalo kumanyolo yizinambuzane namagundane.

4. Izinhlobo ezahlukene zomanyolo kufanele zigcinwe ngokwehlukana ukuze kugwenywe ukungcoliswa okubangelwa ukugcinwa okuxubile.

I-NPK 18-18-18 iyisivundisi esihlanganisiwe esinokuqukethwe okuphezulu, esakhiwe kakhulu yi-nitrogen (N), i-phosphorus (P), kanye ne-potassium (K), enesilinganiso esingu-18-18-18 kanye nokuqukethwe okuphelele kwezakhamzimba okungu-≥ 54%. Lo manyolo ufanelekela izitshalo ezahlukahlukene futhi unemisebenzi eminingi kanye nezici eziningi.
