Kodi humic acid amakonza bwanji nthaka?

Zochita zatsimikizira kuti zotsatira za humic acid pakubwezeretsa nthaka ndikuwongolera ndizodziwikiratu. Amawonetsedwa kwambiri m'magawo atatu:

1. Humic acid amasintha mawonekedwe a zitsulo zolemera mu dothi loipitsidwa

Kuwunjikana ndi kulemeretsa kwa zitsulo zolemera kumabweretsa mavuto aakulu kunthaka. Mitundu yambiri yomwe ilipo m'nthaka ndi chelated kapena zovuta. Humic acid imakhala ndi ma ions ambiri. Ikhoza kusintha dziko la chelated ndi ma ions ake. Ndi ma ayoni olemera kwambiri m'malo ovuta, zitsulo zolemera sizimatengedwa mosavuta ndi mbewu, ndipo mbewu siziipitsidwa mosavuta ndi zitsulo zolemera. Kuwala kwa humic acid (fulvic acid) kumakhala ndi kulemera kochepa kwa maselo, komwe kumapindulitsa kutsegulira, kugwirizanitsa ndi kuwononga zitsulo zolemera. Heavy humic acid (kuphatikizapo palm humic acid ndi black humic acid) imakhala ndi kulemera kwakukulu kwa maselo ndipo imakhala ndi zotsatira zochepetsera ndi kutsatsa ndi kukonza zitsulo zolemera, zomwe zingachepetse mphamvu yazitsulo zolemera, monga kukonza cadmium, mercury, ndi lead. .

2. Humic acid amachepetsa kawopsedwe ka zinthu zachilengedwe m'nthaka yoipitsidwa

Chinanso “chowononga” nthaka ndi zinthu zoipitsa zachilengedwe. Magwero makamaka mafuta ndi pyrolysis mankhwala, mankhwala, organic kupanga mankhwala (monga pulasitiki mulch, etc.); asidi wa humic amatha kukhazikika m'nthaka powonjezera kutengeka ndi kukhazikika kwa zinthu za organic Mwanjira imeneyi, zowononga zimataya ntchito, kapena zimapangitsa kuti ma photolysis ndi kuwonongeka kwa mankhwala azitha kuchitapo kanthu pazachilengedwe, kuti akwaniritse zotsatira zake. za "kuchotsa poizoni" m'nthaka. Humic acid "mulch degradable" wopangidwa ndi heavy humic acid ngati zopangira amasinthidwa kukhala feteleza wa humic acid organic pakatha miyezi iwiri kapena itatu atagwiritsidwa ntchito. Mbewu zimamera mwachibadwa, kupulumutsa ntchito ndi nthawi, ndikupewa "kuipitsa koyera" komwe kumachitika chifukwa cha mulching wa pulasitiki. .

3. Humic acid angagwiritsidwe ntchito pochiza nthaka ya saline-alkali yokhala ndi madzi apansi osakwana 1 mita.

Humic acid akhoza kuphatikiza ndi calcium ndi ayoni chitsulo cha adjuvants ena kulimbikitsa mapangidwe lalikulu tinthu aggregates mu nthaka yabwino ya 20-30 masentimita pamwamba, kuchepetsa capillary chodabwitsa cha nthaka yabwino, ndipo kwambiri. kuchepetsa evaporation ya madzi kunyamula mchere pamwamba ndipo pang`onopang`ono Kudzikundikira salinization ndi njira yothandiza kwambiri kulamulira dziko saline-alkali kuchokera gwero.
