Kumayambiriro kwa masika kulikonse, alimi obzala minda amayamba kusankha feteleza wa mbewu. Kukula ndi kukula kwa mbewu ndikofunikira pakupereka feteleza. Malinga ndi malingaliro a aliyense, mbewu zimafunikira kwambiri nayitrogeni, phosphorous ndi potaziyamu, koma zenizeni, kufunikira kwa calcium ndi mbewu ndikokwera kwambiri kuposa phosphorous.
Nthawi zonse ikagwa mvulacalciumm'mbewu zidzawonongeka kwambiri, chifukwa kutentha kwa mbewu kudzakhala kolimba nyengo itatha, ndipo kuyamwa kwa calcium kudzakhalanso kolimba, motero calcium yomwe ili m'mbewu idzakokoloka mvula ikagwa, zomwe zidzachititsa kuti Calcium ikhale yochepa. mu mbewu, chiwonetsero chodziwikiratu cha kuchepa kwa kashiamu mu mbewu ndikuti chimayambitsa kutentha mu kabichi, kabichi, ndi zina zambiri, zomwe nthawi zambiri timazitcha chikasu cha masamba a masamba, komanso kumayambitsa zowola mu tomato, tsabola, etc.
Mbewu zomwe alimi agwira ntchito mwakhama kwa miyezi ingapo sizingalephereke chifukwa cha kuchepa kwa calcium. Choncho, kashiamu wowonjezera ku mbewu wakhala chinthu chofunika kwambiri kwa alimi.
Pali zinthu zambiri za calcium zowonjezera pamsika, zomwe zimapangitsa alimi ena kusokonezeka. Sakudziwa ngakhale ubwino wosiyana wa zinthu zambiri zowonjezera kashiamu, kotero ndipereka zitsanzo ziwiri za mankhwala owonjezera kashiamu apa, kuti aliyense amvetse bwino. phunzirani.
Calcium Nitrate vsCalcium Formate
calcium nitrate
Calcium nitrate ili ndi calcium yokwana 25. Poyerekeza ndi mankhwala ena owonjezera a calcium, calcium imakhala yochuluka kwambiri. Ndi kristalo yaying'ono yokhala ndi zoyera kapena mitundu ina pang'ono. Ili ndi hygroscopicity yamphamvu ndipo kusungunuka kwake kumakhala kochepa kwambiri chifukwa cha kutentha. Ndiwo mtundu wa calcium wofunikira.
Calcium nitrate akadali wosavuta kuti agglomerate ndi kusungunuka m'madzi, koma chifukwa cha kuchuluka kwake kwa nayitrogeni (mulingo wa nayitrogeni: 15%) ndi feteleza wa nayitrogeni, izi zimapangitsa mbewu kusweka ndi kubala zipatso, komanso zimapangitsa kuti mbewu zikule Mwapang'onopang'ono, koma ndizotsika mtengo.
calcium formate
Kashiamu mu kashiamu formate ndi wamkulu kuposa 30, amene ali bwino kuposa calcium nitrate. Ndi ufa wa crystalline woyera. Ndiosavuta kuyamwa komanso sikophweka kuphatikiza. Ilibe nayitrogeni, choncho musade nkhawa kuti ikugwiritsidwa ntchito limodzi ndi feteleza wa nayitrogeni. Zimawonetsedwa kuti ndizosavuta kugwiritsa ntchito, ndipo zimagwiritsidwa ntchito kwambiri mu feteleza wa granular.
Powombetsa mkota,calcium formateali ndi kashiamu wochuluka ndipo sivuta kuyamwa. Lilibe nayitrogeni. Palibe chifukwa chodera nkhawa za zoopsa zobisika zikagwiritsidwa ntchito ndi feteleza wa nayitrogeni. Mtengo nawonso ndi wotsika poyerekeza ndi calcium nitrate. Aliyense akusankha Mutha kusankha mankhwala owonjezera a calcium oyenera mbewu malinga ndi zosowa zanu.
