Semunhu anotengesa mafetereza nemapakeji efetereza, takazvipira kupa zvigadzirwa zvemhando yepamusoro izvo zvinongokurudzira kukura kwechirimwa chete asiwo zvinotarisisa kukanganisa kwezvakatipoteredza kwekushandisa kwavo. Chimwe chezvigadzirwa zvakakosha mumhando yezvigadzirwa zvedu ammonium chloride, potassium (K) fetireza inoita basa rakakosha mukuvandudza goho nemhando yezvirimwa zvinorimwa muvhu risina kudya kunovaka muviri. Munhau idzi, tichanyatso tarisisa maitiro emakemikari eammonium chloride munyuuye kuongorora maitiro avo pane zvakatipoteredza.
Kemikari zvinhu zveammonium chloride:
Ammonium chloride, kemikari formula NH4Cl, icrystalline munyu inonyungudika zvakanyanya mumvura. Iyo inonzi hygroscopic, zvinoreva kuti inotora hunyoro kubva mumhepo. Iyi pfuma inoita kuti ive tsime rakakosha renitrogen pakuberekesa mbeu nekuti inonyungudika nyore uye inotorwa nemidzi yezvirimwa. Pamusoro pezvo, ammonium chloride yakakwira munitrogen, zvichiita kuti ive sosi inoshanda yezvinovaka muviri zvakakosha pakukura kwechirimwa.
Kana ammonium chloride ikaiswa muvhu, inopinda muitiro unonzi nitrification, umo mabhakitiriya evhu anoshandura nitrogen muchimiro cheammonium (NH4+) kuita nitrate (NO3-). Kupinduka uku kwakakosha nekuti zvirimwa zvinotora nitrogen muchimiro chenitrate. Naizvozvo, ammonium chloride inoshanda sedura renitrogen rinogona kuburitswa zvishoma nezvishoma uye kushandiswa nezvirimwa nekufamba kwenguva.
Kukanganisa kweammonium chloride pane zvakatipoteredza:
Apoammonium chlorideifetireza inoshanda, kushandiswa kwayo kunogona kukanganisa zvakatipoteredza kana ikasabatwa zvakanaka. Chimwe chezvinonyanya kunetsa ndeye mukana we nitrogen leaching. Kunyanya kushandiswa kweammonium chloride kana imwe nitrogen-based fertilizer kunogona kukonzera nitrate kunyura mumvura yepasi, zvichiunza njodzi kumhando yemvura uye zvipenyu zvemumvura.
Pamusoro pezvo, iyo nitrification muvhu inotungamira mukuburitswa kwenitrous oxide (N2O), ine simba greenhouse gasi rinobatsira mukushanduka kwemamiriro ekunze. Zvakakosha kuti varimi nevarapi vezvekurima vatore maitiro ekutonga zvakanaka kuderedza kurasikirwa kwenitrogen uye kudzikisira kukanganisa kwezvakatipoteredza kwekushandiswa kweammonium chloride.
Kushandiswa kwakasimba kweammonium chloride:
Kuti tigadzirise zvinonetsa zvezvakatipoteredza zvine chekuita nazvoammonium chloride munyu, zvakakosha kuti titore maitiro akasimba mukushandiswa kwayo. Izvi zvinosanganisira manejimendi ezvekudya zvinovaka muviri, izvo zvinogadzirisa mazinga ekushandisa kune izvo chaizvo zvinodikanwa zvezvirimwa zviri kurimwa. Pamusoro pezvo, kubatanidza maitiro akadai sekurima kwekuvhara, kutenderedza zvirimwa, uye kushandisa nitrification inhibitors kunogona kubatsira kuderedza nitrogen leaching uye kuderedza kuburitsa gasi regreenhouse.
Muchidimbu, ammonium chloride yakakosha potasium fetiraiza ine simba rakakura pakudya kwezvirimwa uye kukura. Nekudaro, zvimiro zvayo zvemakemikari uye kukanganisa kwezvakatipoteredza zvinofanirwa kunzwisiswa kuve nechokwadi chekushandisa kwayo zvine musoro. Nekusimudzira maitiro ekurima akasimba uye nekusimudzira ruzivo rwekushandiswa kwakakodzera kweammonium chloride, tinogona kushandisa mabhenefiti ayo tichideredza nharaunda yayo. Semutengesi ane hunyanzvi, takazvipira kutsigira vatengi vedu kuti vashandise mafetireza nenzira ine hushamwari kwezvakatipoteredza, zvichibatsira kuhutano hwenguva refu hwezvipenyu zvedu.
