1. Bai wokhala ndi michere yambiri, kuwonjezeka kwakukulu pakupanga

Ndipo ili ndi zinthu zina monga sulfure, chitsulo, zinc, molybdenum, magnesium zhi, ndi zina zotero zomwe zimafunidwa ndi mbeu du. Nthawi yomweyo, malondawa ali ndi mawonekedwe amtundu wa yunifolomu, mtundu wokhazikika, kusungunuka kwabwino, komanso mayesedwe osavuta a mbewu. Ikatha kugwiritsidwa ntchito, imatha kusintha dothi Poyerekeza ndi feteleza wa pakompyuta wopangidwa ndi njira zina, kufalikira kwa michere komwe kumafala kwambiri kumatha kuyamwa mwachangu, kutaya pang'ono, kuthira fetereza wokhalitsa, komanso kukolola kwakukulu.

2. Lonse ntchito zosiyanasiyana

Chogulitsidwacho chili ndi zowonjezera zowonjezera komanso zosakwana 3% muzu wa chloride. Zogulitsazo sizongoyenera mbewu zosiyanasiyana zaulimi monga tirigu, mpunga, chimanga, chiponde, komanso ndizoyenera kulima ndalama monga mitengo yazipatso, masamba, fodya, adyo, ndi ginger. Feteleza m'munsi amathanso kugwiritsidwa ntchito ngati zovala zapamwamba.

3. Kukweza nthaka ndikulimbikitsa chonde m'nthaka

Mankhwalawa alibe zovuta zoyipa, ndipo alibe zovuta pazomera ndi nthaka. Ikatha kugwiritsidwa ntchito, imatha kubweretsanso potaziyamu, zinc, boron ndi zinthu zina m'nthaka, kusintha nthaka, kulimbitsa mphamvu zadziko, komanso kulimbana ndi chilala, kusungitsa chinyezi, ndi malo okhala. Zotsatira Kugwiritsa ntchito kwakanthawi kumatha kukonza nthaka ndikuwonjezera zokolola. Kuti

Momwe mungagwiritsire ntchito potaziyamu sulphate feteleza wapakompyuta:

(1) Thiabendazole angagwiritsidwe ntchito ngati m'munsi fetereza. Litipotaziyamu sulphate Amagwiritsidwa ntchito ngati feteleza m'minda youma, nthaka iyenera kugwiritsidwa ntchito mozama kuti muchepetse kukhazikika kwa timiyala ta potaziyamu ndikuthandizira kuyamwa kwa mizu ya mbewu ndikuwonjezera magwiritsidwe ake.

(2) Amagwiritsidwa ntchito ngati zovala zapamwamba. Popeza potaziyamu imakhala yosayenda pang'ono m'nthaka, imayenera kugwiritsidwa ntchito pamizere yolumikizana kapena m'mabowo panthaka yokhala ndi mizu yolimba yolimbikitsira kuyamwa.

(3) Itha kugwiritsidwa ntchito ngati feteleza wa mbewu ndi kuwonjezera mizu. Kuchuluka kwa fetereza wambewu ndi 1.5-2.5 kg pa mu, ndipo itha kupangidwanso yankho la 2% -3% yothetsera mizu yochulukirapo. Kuti

Potaziyamu sulphatendi mtundu wa feteleza wopanda potaziyamu, wabwino kwambiri komanso wothandiza kwambiri, makamaka pakabzala mbewu zosamvekanso ngati chlorine monga fodya, du mphesa, beets, mitengo ya tiyi, mbatata, fulakesi ndi mitengo yambiri yazipatso. Ndi feteleza Wofunika kwambiri; Imeneyi ndiwonso yopangira feteleza wapamwamba wa nayitrogeni, phosphorous ndi potaziyamu ternary kompositi.
Potaziyamu sulphatefeteleza wamtundu wopangidwa ndi kutentha kwa potaziyamu mankhwala enaake, kaphatikizidwe ka mankhwala, ndi njira yopopera mafuta. Ili ndi bata lokhazikika. Kuphatikiza pa michere itatu yayikulu yofunikira pazomera, N, P ndi K, ilinso ndi S ndi Ca, Mg, Zn, Fe, Cu ndi zina zotsalira. Feteleza wamtunduwu ndi woyenera kubzala mbewu zosiyanasiyana, makamaka zomwe zimakhudzidwa ndi chlorine.
