Kugwiritsa ntchito calcium formate mu feteleza

I. Chiyambi

 Ndi kupititsa patsogolo ulimi wamakono, kufunikira kwa feteleza wogwira ntchito bwino, wokonda zachilengedwe komanso wogwira ntchito zambiri kukukulirakulira. Monga gawo la feteleza watsopano, calcium formate yaperekedwa chidwi kwambiri. Sizingangopereka zakudya zomwe zimafunikira ndi zomera, komanso zimakhala ndi machitidwe apadera a thupi, zomwe zimakhala zofunikira kwambiri kuti zithetse bwino mbeu ndikuwonjezera zokolola.

 Chachiwiri, katundu ndi makhalidwe a kashiamu formate

 Calcium formate, ndi formula ya mankhwala Ca (HCOO)₂, ndi ufa wonyezimira woyera umene umasungunuka mosavuta m’madzi. Kashiamu yake imakhala yochuluka, mpaka pafupifupi 30%, pomwe imakhala ndi mawonekedwe enaake, okhala ndi acidic.

 Chachitatu, ntchito ya kashiamu formate fetereza

 (1) Perekani calcium

Calcium ndi imodzi mwazinthu zofunika kwambiri pakukula kwa mbewu, ndipo imagwira ntchito yofunika kwambiri pakumanga khoma la cell, kukhazikika kwa kaphatikizidwe ka cell membrane, ndikuwongolera kagayidwe ka cell. Kashiamu mu calcium formate amatha kuyamwa mwachangu ndikugwiritsiridwa ntchito ndi zomera, kuteteza ndi kukonza bwino zizindikiro za kuchepa kwa kashiamu mu zomera, monga zipatso zosweka ndi zowola za umbilical.

 (2) Kusintha nthaka pH

Calcium formate ali ndi acidity, akhoza kuchepetsa nthaka pH mtengo pambuyo ntchito, makamaka zamchere nthaka, kusintha nthaka thupi ndi mankhwala katundu, kusintha kupezeka kwa zakudya.

 (3) Limbikitsani kukula kwa mizu

Formate ikhoza kulimbikitsa kukula kwa mizu ya zomera ndikuwonjezera mphamvu ya mizu kuyamwa zakudya ndi madzi, kuti apititse patsogolo kukana ndi kukula kwa nyonga ya zomera.

 (4) Kupititsa patsogolo photosynthesis

Kuchuluka kwa kashiamu koyenera kungathe kuwonjezera zomwe zili mu chlorophyll m'masamba a zomera, kupititsa patsogolo mphamvu ya photosynthesis, kulimbikitsa kaphatikizidwe ndi kudzikundikira kwa chakudya, komanso kupereka mphamvu zambiri ndi maziko a zomera.

 Kugwiritsa ntchito kashiamu formate zosiyanasiyana nthaka

 (1) Dothi la asidi

Mu dothi la acidity, acidity ya calcium formate imakhala yofooka, komabe imatha kupereka calcium yofunikira ku zomera. Akagwiritsidwa ntchito, chidwi chiyenera kuperekedwa ku kugwirizana ndi feteleza wina wamchere kuti nthaka ikhale ndi pH.

 (2) Dothi lamchere

Pa dothi lamchere, mphamvu ya acidification ya calcium formate ndiyofunika kwambiri, yomwe imatha kuchepetsa pH ya nthaka, kukonza dothi, kukulitsa kutulutsa kwa nthaka ndi kusunga madzi. Panthawi imodzimodziyo, calcium yomwe imapereka imatha kuchepetsa vuto la kuchepa kwa calcin chifukwa cha kusungunuka kwa nthaka.

 (3) nthaka ya saline-alkali

M'dziko la saline-alkali, calcium formate amatha kuchepetsa mchere wamchere m'nthaka ndikuchepetsa mphamvu ya mchere pa zomera. Komabe, kuchuluka kwake komwe kumagwiritsidwa ntchito kuyenera kuyendetsedwa mosamalitsa kuti mchere usachuluke m'nthaka.

 Chachisanu, synergistic zotsatira za kashiamu formate ndi zigawo zina feteleza

 (A) ndi nayitrogeni, phosphorous, potaziyamu feteleza

Kuphatikizika kwa kashiamu mawonekedwe ndi nayitrogeni, phosphorous, potaziyamu ndi zinthu zina kumatha kusintha kuchuluka kwa feteleza, kulimbikitsa kuchuluka kwa michere, ndikukwaniritsa synergistic.

 (2) Feteleza wokhala ndi ma trace elements

Ndi chitsulo, zinc, manganese ndi feteleza wina wa trace element, amatha kusintha magwiridwe antchito a zinthu, kupewa ndikuwongolera kuchepa kwa zinthu.

 (3) Ndi feteleza wachilengedwe

Kuphatikizika ndi feteleza wachilengedwe, kumatha kusintha malo okhala m'nthaka, kulimbikitsa kuwonongeka ndi kutulutsa michere kwa feteleza wachilengedwe, komanso kukulitsa chonde m'nthaka.

 Six, ntchito kashiamu formate fetereza ndi kusamala

 (1) Njira zogwiritsira ntchito

Calcium formate ingagwiritsidwe ntchito ngati feteleza woyambira, feteleza wowonjezera kapena feteleza wa foliar. Kuchuluka kwa feteleza wapansi nthawi zambiri kumakhala 20-50 kg pa mu; Topdressing itha kugwiritsidwa ntchito molingana ndi kukula kwa mbewu komanso kufunika kwa feteleza. The masamba kupopera ndende zambiri 0.1% -0.3%.

 (2) Kusamala

 Yang'anirani kwambiri kuchuluka kwa ntchito kuti mupewe acidity ya dothi kapena calcin wochulukirapo chifukwa chakuthira kwambiri.

Samalirani kuchuluka kwa feteleza ena, ndipo pangani gawo loyenera malinga ndi chonde cha nthaka ndi zokolola.

Ikasungidwa, iyenera kukhala yoteteza chinyezi, yoteteza ku dzuwa, ndikupewa kusakanikirana ndi zinthu zamchere.

 Vii. Mapeto

Monga gawo latsopano la feteleza, calcium formate imathandizira kwambiri popereka zakudya za calcium ya zomera, kuwongolera pH ya nthaka ndi kulimbikitsa kukula kwa mizu. Kugwiritsiridwa ntchito moyenerera kwa feteleza wa calcium formate kumatha kupititsa patsogolo zokolola ndi ubwino wa mbewu, kusintha malo a nthaka, ndi kupereka chithandizo champhamvu cha chitukuko chokhazikika chaulimi. Komabe, m'machitidwe ogwiritsira ntchito, ndikofunikirabe kusankha mwasayansi komanso moyenera ndikugwiritsa ntchito molingana ndi mikhalidwe yosiyanasiyana ya nthaka ndi zosowa za mbewu kuti athe kuchita bwino pazabwino zake ndikupeza ulimi wothandiza komanso wosamala zachilengedwe.
