Umanyolo we-potassium sulphate

I-potassium sulphate iyimanyolo e-concentassium egxile kakhulu, ehlanganisa i-potassium engu-50%, i-18% yesulfure, i-magnesium engu-3 ne-0.4% ye-calcium. Ngokubukeka kumhlophe, ngezinye izikhathi nge-grayish hue, i-powder crystalline. I-potassium sulphate ayiqukethe i-chlorine nezindawo zayo eziyinhloko yi-solubility enhle emanzini nokuthi ayizikhekhe uma igcinwe isikhathi eside.

Indlela yokusebenzisa i-potassium sulfate?

Ukusetshenziswa kwe-potassium sulfate ne-nitrogen kanye ne-phosphate fertilizer kuthuthukisa umphumela omuhle ekukhiqizeni, kodwa ukusetshenziswa okufanayo kanye ne-urea, isikhombisi asikhuthazwa.

Isetshenziswa kabanzi kwezolimo potassium sulphate njengoba umanyolo uthola, ngoba:

• ukwandisa okuqukethwe kwamavithamini noshukela ezitshalweni;
• ngokuthinta i-volume kanye nekhwalithi yesitshalo;
• kunomthelela ekubambeni kwebusika okuphumelelayo kwezithelo nezihlahla zeberry kanye nezihlahla;
• ingasetshenziswa emhlabathini owodwa (sod-podzolic, peat, chestnut, sulfuric, acidic).

I-potassium sulfate ingasetshenziswa evulekile nasemhlabathini ovaliwe (greenhouse), kanye nezitshalo zasendlini.

Uma ingena emhlabathini, i-potassium, engxenyeni yomanyolo we-potash, idlula enhlabathini eyinkimbinkimbi, eyabe isetshenziswe izitshalo. Ehlabathini nobumba obuhle, i-potassium sulphate isungulwe futhi cishe ayifinyeleli emigqeni engaphansi komhlaba, futhi emhlabathini owunhlabathi onesihlabathi - ukuhamba kwe-potassium kuphakeme. Ngakho-ke, ukuze unikeze izitshalo nge-potassium eyanele, bazama ukwenza kube ungqimba lapho iningi lezimpande litholakala khona. Ehlabathini enzima, umanyolo we-potassium kufanele usetshenziswe ekwindla ukujula okukhulu, nasemhlabathini onesihlabathi entwasahlobo futhi ngaphandle kokujula. Isibonelo, lapho uhlwanyela umuthi wezithelo emhlabathini okhanyayo kanye neloamy phansi komgodi wokufika, kuyadingeka ukwengeza i-potassium sulfate kanye ne-phosphate fertilizer, njengoba isingeniso esilandelayo se-potassium umquba enhlabathini engenhla angeke sinikeze umuthi wesithelo isisindo esidingekayo se-potassium.

Indlela yokusebenzisa i-potassium sulfate?

I-potassium sulphate ingenziwa ngezindlela ezimbili:

• entwasahlobo noma ekwindla ene-digging enkulu yenhlabathi;
• njengokugqoka okuphezulu ngesikhathi sokukhula.

Ukusetshenziswa kwe-potassium sulfate kungenzeka ngamaqembu alandelayo wezitshalo:

• ukuzwela ku-chlorine ( amagilebhisi , amazambane, ifilakisi, ugwayi, i-citrus);
• umndeni cruciferous (rutabaga, iklabishi, itheniphu, itheniphu, isithombo);
• ukudla okuningi kwesulfure (ubhontshisi);
• izihlahla-berry izihlahla kanye ezihlabayo (gooseberries, cherry, plums , ithini lamapheya, raspberries kanye apula-izihlahla).

Umthamo wokusetshenziswa komanyolo onjalo uncike endleleni yokusebenza kanye nohlobo lwesitshalo:

• ku-main application for strawberries, utamatisi, ukhukhamba nezimbali - 15-20 g / m2, iklabishi, beet, izaqathe, amazambane - 25-30 g / m2;
• lapho uhlwanyela izihlahla zezithelo - 150-200 g ngomgodi wokugibela;
• ukugqoka okuphezulu kwezitshalo zemifino kanye ne-strawberries - 10-15g / m2, iberry ezihlabayo - 15-20g / m2 noma ukwenza ama-grooves 6-8cm ejulile eduze kwezitshalo eziseduze nezitshalo, benza 50-100g / m2 lapho.

Uma ukugqoka okuphezulu kwenziwa ngesistimu yokunisela, kufanele kulungiselelwe isisombululo se-potassium sulfate nge-concentration 0.05-0.1%, ngokugcoba okuphezulu kwe-foliar ekufakeni noma yiziphi izinhlelo zokuphalaza Isixazululo sika-1-3%, kanye nokunisela okujwayelekile, ama-10-40 amalitha amanzi ahlanjululwa ngamalitha angu-10 amanzi, kanti le nsimu isetshenziselwa izitshalo eziyi-10-20.

I-potassium sulfate ayinayo izinto ezinobuthi nokungcola, kodwa uma ithola esikhumbeni, emehlweni noma ngaphakathi, ingabangela ukucasuka kwamangqamuzana amangcwaba, amacala enobuthi angavamile ngokweqile, ngokuchayeka isikhathi eside kakhulu.

Kuzolimo, i-potassium sulfate isetshenziswa njengomanyolo kaningi, ngoba ayinalo i-chlorine, futhi i-potassium ifakwe kahle kuyo, okudingekayo ukuthola imikhiqizo ephezulu, ukunciphisa ukulahlekelwa kwezitshalo ngesikhathi sokugcina, nokuphikiswa okuphezulu kwezifo nezinambuzane.
