I-Potassium sulphate, isichumisi esinceda ukulawula ubungakanani beziqhamo kunye nomgangatho waso

Izityalo badinga uthotho lwezondlo ukuze bakwazi ukukhula nokukhula, ezifana ne-phosphorus, i-nitrogen kunye ne-calcium. Zonke zibaluleke kakhulu, kangangokuba ukugqithisa okanye ukungabikho kwesinye kuzo kuya kubenza bagule kumcimbi wexesha, onokuba ngaphezulu okanye ngaphantsi ubude kuxhomekeke ekubalulekeni kwawo. Ke, ukuba uswele intsimbi, amagqabi akho aya kuba yiklorotic ngokukhawuleza kwaye ayeke ukukhula, kodwa ukuba awunayo i-boron kuya kuthatha ixesha elide ukubonisa iimpawu.

Ngale nto engqondweni, kubalulekile ukuba bahlawulwe rhoqo ukubathintela ekuguleni. Ngantoni? Kuya kuxhomekeka kuhlobo lwesityalo nakwinto esinomdla wokuyiphumeza. Ngeli xesha siza kugxila kwi potassium sulfateisichumiso esiza kunceda ukulawula ukukhula kunye nokutyeba kweziqhamo.

Zisebenzisa ntoni i-potassium?

I-Potassium ifumaneka emhlabeni ukusuka kwii-silicates ematyeni kunye neemaminerali zemagmatic ezinje nge micas kunye ne feldspars. Singahlula iintlobo ezintathu:

• Ngqo i-potassium efumanekayo: Yeyona ilungisiweyo kumphezulu wodongwe nakwintsimbi yomdongwe-humic.
• I-potassium engaphakathi: ifumaneka phakathi kwamashiti odongwe. Iingcambu zinobunzima bokuyifunxa.
• Potassium kwiqhekeza lezimbiwaIyafumaneka emhlabeni, kodwa ayinako ukufunxwa yingcambu zezityalo ngaphandle kokuba yonakaliswe ziintsholongwane.

Esi sondlo sinayo imisebenzi ebaluleke kakhulu yezityalo:

• Iqinisekisa ukuba iiseli azisweli manzi, ngenxa yoko inxulumene nokutyeba kunye nomgangatho wesiqhamo.
• Ilawula ukungena kweeseli, oko kuthetha ukuba kulahleka amanzi amancinci, kokukhona iziqhamo ziya kugcinwa.
• Inegalelo ekuphuculeni ukunganyangeki okubandayo kwezityalo ngokumisela uxinizelelo olunetyuwa lweejusi zeselula.
• Iphucula ukumelana nembalela, nanjengoko inciphisa isantya sokubila.
• Kuyanceda ukwenza iiswekile, kunika iziqhamo incasa emnandi.

Yintoni i-potassium sulphate?

I-Potassium sulphate yifayile ye- i-potassium ityuwa ye-sulfuric acid. Sesinye sezichumisi ezinomdla kakhulu kwizityalo ezikhulayo, ngakumbi ezasemanzini, kuba ayinayo iklorine. Idibanisa izondlo ezibini ezibalulekileyo: i-potassium nesalfure, zombini ezifumaneka kwizityalo.

Ngokwesiqhelo, ubungakanani kunye nobutyebi beli sichumiso ngu 50%, kwaye oku kunxulumene neeyunithi zezichumisi (UF). Ukuseka isixa sesichumisi se-potassium esongezwa kwisityalo (ngokwe-UF) kunye ne-potassium sulphate, kwenziwa ngolu lwalamano lulandelayo:

I-100 FU ye-potassium kwinkcubeko = 200kg ye-potassium e-soluble yamanzi, i-K2O (50%).

Inokusetyenziswa nini?

I-Potassium sulphate sisichumiso esinokusetyenziswa xa sisonke ixesha lokuchumaOko kukuthi, ukusuka kumzuzu wokuqala apho intyatyambo idluliselwa ipoleni kude kube ziiveki ezimbini ngaphambi kokuvunwa kweziqhamo. Kodwa, ewe, inokusetyenziswa kuphela ukuba sinomhlaba wealkaline, oko kukuthi, nge-pH ephezulu, kuba ikwasebenza njengenciphisi ye-pH.

Njengengcebiso, ukuba unkcenkceshelwa ngokufefa, ungongeza phakathi kwe-1 kunye ne-2,5 yeegram / ilitha yamanzi; kwaye ukuba ithontsiza ukusuka kwi-2 kuye kwi-9kg kwi-100 yeelitha zamanzi. Nangona kunjalo, kuya kufuneka uyazi ukuba isixa siyahluka ngokuxhomekeka kwi-pH yomhlaba, ngaphambi kokuba uqalise ukuchumisa izityalo ngayo, kubalulekile ukwenza uhlalutyo lomhlaba njengoko umhlaba unokuba namanqanaba afanelekileyo e-potassium kwaye ke ngenxa yoko ukuchumisa i-potassium sulphate akuyomfuneko.

Izityalo eziphendula kakuhle kwesi sichumiso yimithi yeziqhamo, imithi yebhanana, iimbotyi, iikhaphetshu, phakathi kwezinye.

Zifuna kangakanani potassium?

Iya kuxhomekeka kuhlobo lwesityalo, kodwa ezo zikhulele amagqabi kunye / okanye iziqhamo zifuna okuninzi. Umzekelo (ithathwe kwi- Isikhokelo esiSebenzayo soChumiso oluQokelelweyo lweZityalo eSpain):

Izityalo zangaphandle:

• IBroccoli (15/20 t / ha): 370-450kg / ha
• Isipinashi (22-28 t / ha): 180-220kg / ha
• I-Melon (30-40 t / ha): 250-330kg / ha
• Sandía (45-55 t / ha): 180-220kg / ha
• Tomate (55-65 t / ha): 300-330kg / ha

Ndazi njani ukuba isityalo sam asikho kwi-potassium?

Ukuba isityalo sinqongophele nge potassium, siyakubonisa ezi mpawu:

• IChlorosis: amagqabi aphakathi kunye asezantsi azakuqala ukubonakala atyheli, ukuqala emaphethelweni ngaphakathi.
• Ukukhula kancinci, phantse kube ngu-zero: ukungabinayo i-potassium eyaneleyo, isityalo asizukukhula.
• Ukunciphisa ukumelana nokubanda kunye nokungabikho kwamanziKuya kubakho amanzi amancinci ajikeleza kwisityalo ngenxa yokunqongophala kwe potassium, yiyo loo nto iya kuba semngciphekweni wobanda nakwimbalela.
• Ukuchaswa: ukuba ukusilela akulungiswa, isityalo sinokulahlekelwa ngawo onke amagqabi.
• Ukuvuthwa kweziqhamo okungalinganiyo: i-potassium ibaluleke kakhulu kuphuhliso lweziqhamo; Ukuba ayikho ngokwaneleyo, abayi kukwazi ukuvuthwa ngokufanelekileyo.
• Ukuxhathisa okuphantsi kwizitshabalalisi-Xasinayo yonke into efunekayo, isityalo siba buthathaka, ngenxa yoko asikwazi ukuzikhusela kwizitshabalalisi.

Kwaye oku sigqibile. Njengoko ubonile, i-potassium yinto ebaluleke kakhulu kwizityalo, kunye ne-potassium sulphate sisichumiso esinconyelwa kakhulu ukuze zikhule ngaphandle kwengxaki.
