1. Nitrogen fertilizer: Inogona kukurudzira kukura kwematavi emiti nemashizha, kuwedzera photosynthesis yemiti, kuwedzera chlorophyll content, uye kunatsiridza kubereka kwevhu.
2. Fotereza yePhosphate: Kurudzira kuumbwa nekutumbuka kwemaruva, ita kuti madzinde echirimwa uye matavi akome, michero yakakura nokukurumidza, uye kunatsa kutonhora kwechirimwa nekusanaya kwemvura.
3. Fetereza yePotassium: Vandudza dzinde rechirimwa, simbisa kurwisa zvirwere zvechirimwa, kusabatwa netumbuyu, uye kusanaya kwemvura, uye kunatsiridza kunaka kwezvibereko.
1, Basa reNPK Fertilizer
N. P neK zvinoreva fetereza yenitrogen, fetereza yephosphorus, nefetireza yepotassium, uye mabasa azvo ndeaya anotevera.
1. Fetereza yeNitrogen
(1) Batsira chirimwa photosynthesis, kusimudzira bazi rechirimwa uye kukura kwemashizha, kuwedzera chlorophyll zvirimo, uye kunatsiridza kubereka kwevhu.
(2) Kana pane kushaikwa kwenitrogen fertilizer, zvirimwa zvinova zvipfupi, mashizha awo anoshanduka akatsvuka uye akasvibira, kukura kwavo kunonoka, uye havazokwanisi kutumbuka.
(3) Kana pane yakawandisa nitrogen fertilizer, chirimwa chemuti chichava chakapfava, madzinde uye mashizha zvichava zvakanyanyisa kureba, kudzivirira kutonhora kuchaderedzwa, uye zviri nyore kutapukirwa nezvirwere uye zvipembenene.
2. Fotereza yePhosphate
(1) Basa rayo nderekuita kuti madzinde nematavi emiti zviome, kukurudzira kuumbwa uye kutumbuka kwemaruva emaruva, kuita kuti michero ikure nekukurumidza, uye kugadzirisa kusanaya kwemvura uye kutonhora kwemiti.
(2) Kana zvinomera zvisina phosphatefetereza, zvinokura zvishoma nezvishoma, mashizha awo, maruva nemichero zvidiki, uye michero yawo inononoka kukura.
3. Fetereza yePotassium
(1) Basa rayo nderekuita kuti dzinde dzechirimwa dzive dzakasimba, kukurudzira kukura kwemidzi, kunatsiridza kurwisa kwechirwere chezvirimwa, kurwisa zvipembenene, kusanaya kwemvura, kuramba kwekugara, uye kuvandudza kunaka kwemichero.
(2) Kana pane kushayikwa kwe potassium fertilizer, necrotic mavara achaonekwa pamashizha emiti yemiti, inoteverwa nekuoma uye necrosis.
(3) Yakawandisa potassium fetiraiza inotungamira kupfupiso yechirimwa internodes, yakapfupikiswa miviri yechirimwa, yero mashizha, uye mumatambudziko akaomarara, rufu.
2, Fetereza yerudzii inoitaNPK feterezandezva?
1. Fetereza yeNitrogen
(1) Nitrogen ndiyo chikamu chikuru chekudya kwefetiraiza, kunyanya kusanganisira urea, Ammonium bicarbonate, ammonia, ammonium chloride, Ammonium nitrate, ammonium sulfate, nezvimwewo. Urea ndiyo fetireza yakasimba ine nitrogen yakawanda.
(2) Kune marudzi akasiyana-siyana emafetireza enitrogen, anogona kukamurwa kuita fetiraiza yenitrogen nitrogen, ammonium nitrate nitrogen fertilizer, cyanamide nitrogen fertilizer, ammonia nitrogen fertilizer, ammonium nitrogen fertilizer, uye amide nitrogen fertilizer.
2. Fotereza yePhosphate
Chikafu chikuru chefetereza iphosphorous, kunyanya kusanganisira Superphosphate, calcium magnesium phosphate, phosphate rock powder, bone meal (mhuka yepfupa chikafu, hove bone meal), rice bran, hove scale, Guano, etc.
3. Fetereza yePotassium
Potassium sulfate, Potassium nitrate, Potassium chloride, Wood ash, etc. Potassium sulfate, Potassium nitrate, Potassium chloride, Wood ash, nezvimwewo.
