Sapropel monga feteleza

Osati onse okonda maluwa amadziwa zomwe sapropel ali. Pakalipano, amagwiritsidwa ntchito kwambiri popanga mbewu, kusamalira nyama komanso ngakhale mankhwala. Tiyeni tiwone chomwe chiri chochititsa chidwi chotere monga sapropel, kumene chichotsedwe ndi zomwe zimagwiritsidwa ntchito pa ulimi.

Sapropel ndi katundu wake

Sapropel ndi ndalama zomwe zimakhala pansi pamadzi a madzi abwino kwa zaka zambiri. Mwa anthu sapropel amangotchedwa matope - mawu awa ndi ozolowereka kwa aliyense. Amakhala ndi tizilombo tating'ono kwambiri tomwe timadya masamba ndi zinyama ndi kuwonjezera mchere wambiri. Zotsatirazi ndi monga nayitrogeni, phosphorus ndi potaziyamu, chitsulo ndi manganese, mkuwa ndi boron, ndi zina zambiri. Mavitamini apansi amakhalanso ndi mavitamini a B , ndipo amakhalanso ndi carotenoids ndi michere. M'mawu ena, sludge yowonjezereka ndi chinthu chofunika kwambiri chomwe chimakhudza nthaka ndi chikhalidwe chokula. Ikhoza kugwiritsidwa ntchito ngakhale mu mawonekedwe ake monga feteleza chosavuta kumunda.

Kuti apange feteleza, sapropel imayendetsedwa ndi mafakitale, pambuyo pake youma ndi kuchitidwa moyenera. Zotsatira zake ndi mankhwala owuma ngati mawonekedwe a ufa, zomwe mungathe kuziwaza pamwamba pa nthaka kapena kuwonjezera pa nthaka.

Sapropel yotengedwa m'mabotolo osiyanasiyana amasiyana mosiyanasiyana, yomwe imadalira mozungulira nthaka. Pali carbonate, organic, ferrous ndi siliceous mitundu ya sapropel. Ikhoza kutsimikiziridwa ndi kusanthula mankhwala. Zimakhudza mwachindunji momwe sapropel ya mitundu iyi imagwiritsidwira ntchito pakukula kwa mbewu. Tiyeni tiwone momwe tingagwiritsire ntchito sapropel monga feteleza.

Kugwiritsa ntchito sapropel monga feteleza

Mosiyana ndi peat, feteleza yotchedwa sapropel imakhala ndi zinthu zambiri zowonjezera zitsamba, chakudya ndi amino acid. Izi zimapangitsa sapropel njira zowonjezera, koma osati nthawi zonse. Ngati peat amagwiritsidwa ntchito makamaka kuti nthaka ikhale yopindulitsa ndi humus, feteleza kuchokera ku silt ali ndi zotsatira zotsatirazi:

• nthaka;
• zowonjezera zake;
• kusintha kwa mizu ya zomera;
• kuonjezera zokolola;
• Kupititsa patsogolo dothi la nthaka monga kuyamwa ndi kusunga madzi;
• kuwonjezereka kwa zamoyo zam'madzi;
• kuyeretsa kwa tizilombo toyambitsa matenda ndi bowa.

Chinthu china chosatsutsika cha sapropel monga feteleza ndi chiyanjano cha chilengedwe. Mosiyana ndi feteleza zamchere, zimakhala zotetezeka kwa anthu ndi nyama. Ndipo poyerekezera ndi manyowa, omwe muli tizilombo toyambitsa matenda ndi mbewu za namsongole, zomwe zimakhala zosiyana ndi izi zimakhala zabwino.

Pankhani yogwiritsira ntchito sapropel, imagwiritsidwa ntchito pa nthaka yovomerezeka ndi feteleza. Pachiyambi choyamba, sapropel imayambira matani pafupifupi 35-40 pa 1 ha nthaka (kwa tirigu) kapena matani 65-70 (zamasamba ndi mbewu zosiyanasiyana). Izi ndi zizindikiro zowonjezera, zomwe zimagwiritsidwa ntchito makamaka kuti zikhale bwino ndi nthaka. Ngati cholinga chanu chachikulu ndi kuonjezera zokolola, ndizomveka kuonjezera mlingo wa ntchito ya feteleza ndi 15-20%. Pankhani iyi, zidzakhala zokwanira kupanga feteleza chotero zaka zitatu kapena zinayi zilizonse. Kutentha nthaka ndi sapropel chaka chilichonse sikofunika, popeza kungayambitse - kuchepetsa mineralization, zomwe sizikhala ndi zotsatira zabwino pa mbewu zambiri.

Tiyenera kukumbukira kuti kugwiritsa ntchito sapropel nthawi zambiri kumakhala bwino pa mchenga loamy ndi mchenga wa m'mapapo ndi mitundu yowawa. Pachifukwa ichi, zotsatira zabwino zimapezeka poyambira pa nthaka.
