Ubwino Wa Sulfato De Amonia 21% Min: Feteleza Wamphamvu Kuti Zibereke Bwino Kwambiri

Tsegulani:

Muulimi, kufunafuna zokolola zabwino kwambiri kumakhalabe cholinga chofunikira kwa alimi padziko lonse lapansi. Kuti izi zitheke, feteleza wogwira ntchito ayenera kugwiritsidwa ntchito kuti apereke zakudya zofunikira kuti mbewu zikule bwino. Mwa feteleza osiyanasiyana omwe amapezeka pamsika,sulfato de amonia 21% minimatuluka ngati yankho lamphamvu lomwe limathandiza kukulitsa zokolola za mbewu chifukwa cha kuchuluka kwake komanso mapindu ake.

1. Ululani zomwe zidapangidwa:

Sulfato de amonia 21% min, yomwe imadziwikanso kutiammonium sulphate, ndi feteleza wokhala ndi nayitrogeni wochepera 21%. Kapangidwe kameneka kamapangitsa kukhala gwero lolemera la nayitrogeni wa zomera, michere yofunika kwambiri pakukula ndi kukula kwa mbewu zonse. Kuchuluka kwa nayitrogeni kumapangitsa mbewu kukhala ndi mafuta ofunikira kulimbikitsa kukula kwa masamba, kulimbikitsa mapangidwe a masamba, ndikulemeretsa kupanga mapuloteni, michere, ndi chlorophyll.

2. Kutulutsa kokwanira kwa nayitrogeni:

Chimodzi mwazinthu zodziwika bwino za 21% min sulfato de amonia ndikutulutsa kwake kwapang'onopang'ono komanso kosasunthika kwa nayitrogeni. Nayitrogeni mu fetelezayu amakhala makamaka mu mawonekedwe a ammonium, motero amachepetsa kutayika kwa nayitrogeni kudzera mu volatilization, leaching ndi denitrification. Izi zikutanthauza kuti alimi atha kudalira fetelezayu ngati njira yothetsera nthawi yayitali, kuonetsetsa kuti mbeu zizikhala ndi nayitrogeni pa nthawi yonse ya kukula kwawo. Kutulutsa kolamuliridwa kwa nayitrogeni sikumangowonjezera kumera kwa mbewu komanso kumachepetsa kuwonongeka kwa chilengedwe komwe kumakhudzana ndi kutayika kwa nayitrogeni wochulukirapo.

3. Kuwongolera nthaka ndi kusintha pH:

Kuphatikiza pa kukhudza kwachindunji kwa mbeu, kuchotsa sulphate yoposa 21% ya ammonia kumathandizanso kukonza nthaka. Akagwiritsidwa ntchito m'nthaka, ayoni a sulphate mu feteleza amathandizira kulimbitsa dothi, kupititsa patsogolo madzi kulowa, ndikuwonjezera mphamvu ya ma cations. Kuphatikiza apo, ma ion ammonium omwe amatulutsidwa pakuwola kwa feteleza amakhala ngati nthaka yachilengedwe ya acidifier, kusintha pH ya nthaka yamchere kuti pakhale malo abwino oti mbewu zikule.

4. Kugwirizana ndi Kusinthasintha:

Sulfato de amonia 21% min imakhala yogwirizana kwambiri ndi feteleza ena ndi agrochemicals, zomwe zimathandizira kugwiritsidwa ntchito kwake m'machitidwe osiyanasiyana akukula. Zomwe zimasungunuka m'madzi zimapangitsa kuti zikhale zosavuta kuphatikiza ndi feteleza zina ndikuzigwiritsa ntchito kudzera munjira zosiyanasiyana za ulimi wothirira, kuphatikizapo kuthirira. Kusinthasintha kwa njira yogwiritsira ntchito imeneyi kumathandiza alimi kuti azitha kukonza bwino kasamalidwe ka feteleza kuti akwaniritse zosowa zawo.

5. Kutheka pazachuma:

Poganizira zazachuma, sulphate ammonia yokhala ndi 21% imakhala njira yokongola ya fetereza. Amapereka njira yotsika mtengo kuposa feteleza ena opangidwa ndi nayitrogeni popeza amapereka nayitrogeni wokwanira pamtengo wopikisana. Kuonjezera apo, kugwira ntchito kwake kwa nthawi yaitali kumachepetsa kufunika kobwerezabwereza kawirikawiri, kupatsa alimi ndalama zochepetsera ndalama pamene akuwonetsetsa kuti mbeu zikukula komanso zokolola zambiri.

Pomaliza:

Sulfato de amonia 21% min ndi feteleza wamphamvu yemwe amagwira ntchito yofunika kwambiri pakukulitsa zokolola. Kuchuluka kwake kwa nayitrogeni, kutulutsa kokhazikika, kuwongolera nthaka, kugwirizana ndi kudalirika kwachuma kumapangitsa kukhala chisankho choyamba kwa alimi omwe akufuna kukulitsa zokolola. Pogwiritsa ntchito mapindu a fetelezayu, alimi amatha kukulitsa kukula kwa mbewu, kuchulukitsa zokolola, ndikuthandizira kuti pakhale ntchito zaulimi zokhazikika komanso zopindulitsa.
