Kazhinji, chii chinotarisa kunze kwekushandisa ivhu rekugadza chinodiwa kuti zvive nani kukura kwezvirimwa zvine makemikari. Kazhinji kacho, nitrogen, potassium, phosphorus, magnesium uye sulfure zvinowanikwa. Kuita kuti kushandiswa kwema mineral fertilizer iite, imwe inogona kutora kugadzirisa kwakaoma, semuenzaniso nitrofoscu. Nezvei uye isu tichataura munyaya ino.
Ndeipi chikamu che nitrofoski?
Izvo zvikamu chikuru zve nitrofoski ndeyitrogen, phosphorus uye potassium. Dzinomiririrwa mairi muzvikamu zvakaenzana (11-16% yega roga), zvese zvinoshandiswa nemamwe salt uye zvisina kuchena.
Nitrophos inowanikwa semagumisiro matatu. Kutanga, phosphate inobatwa ne nitric acid, uye ammonium sulfate (kana ammonia ine sulfuric kana phosphoric acid) inowedzerwa, uye potassium chloride inowanikwa pakuguma. Zvichienderana nekushandurwa kwemaitiro ekugadzirwa, i sulphate, sulfate uye phosphoric.
Nitrofoska inogadziriswa gorole. Nokudaro, vasati vawedzera, zviri nani kuputira mumvura, uye kugoverwa muvhu kuchava yunifomu yakawanda. Apo pavanopinda muvhu, vanokurumidza kuputsika muzvioni, izvo zvinofananidzwa pasina zvinetso nezvirimwa. Kuvonga nekurapwa kwakakwana, nitrofoska inochengetwa kwenguva yakareba kwazvo isina caking.
Mirayiridzo yekushandiswa kwe nitrofossi fertilizer
Shandisa nitrofosca inokurudzirwa pazvivako zvine acidic kana kuti zvisiri zvematongerwo enyika, asi, kana zvakakodzera, zvinogona kushandiswa pane chero. Iyo inoshanda zvikuru inoshanda pajecha, ivhu uye peat bog. Iwe unogona kuzviita panguva yekugadzirira kwenyika yekudyara, panguva yekudyara uye semafuta munguva yekukura kwemwaka. Panzvimbo dzine nzara, zviri nani kuita izvi mukutenderera, kuidzikisa zvakanaka muvhu, pazviedza - mukati megore uye pedyo nepamusoro.
Nitrofosco inogona kushandiswa pamiti yose yemiriwo ( mbatatisi , shuga beet, maruva , etc.), majeki, matsiro emichero nemiti.
Zvirimwa zvinopindura zvisina kunaka kwete chete nekushaikwa kwezvinhu zvemakemikari, asiwo kudarika-kuyanisa pamwe navo, saka zvakakosha kuti mbeu imwe neimwe ichengetedze kuyerwa kwemukati:
- Kana uchidyara mbeu yemichero yemichero nemaruva - 5 - 7 g pa 1 m & sup2.
- Nokuda kwemazamu uye kudyara mbeu nekudyara nzira - 4 - 6 g munharaunda imwe neimwe yekudyara.
- Newe strawberries nemaswisi - 40 - 45 gramu pamusango.
- Kune michero yezvibereko - 60 - 150 g, zvichienderana nokupararira.
- Pamiti - 200 - 250 g muduku uye 450-600 g vanhu vakuru.
Kungovandudza unhu hwevhu, i.e. inowedzera kubereka kwayo, inofanira kuwedzerwa nitrophosphate pachiyero che 90 g pa 1 m & sup2. Kana uchisimudza mbeu mumwaka mushure mokupenya, unofanira kunatsa 2 tablespoons yegranules mu 10 malita emvura uye mvura yemiti nemugumisiro unoguma.
Zvichienderana nezvirimwa zvakasimwa uye zvimwe zvezvicherwa mumunda, kushandiswa kwe nitrophosphate kunogona kuwedzera kuwedzerwa kwemashonga ari nyore (zvakasiyana potassium, phosphorus kana nitrogen).
Inowanzovhiringidza ma fertilizer maviri, akafanana nezita - nitrofosca uye nitroammofosku. Ngationei, ndechipi kusiyana kwavo, kana kuti ivo vanogona kuva mishonga imwe chete.
Kusiyanisa pakati pe nitrophosphate uye nitroammofosci
Izvi zvinoshandiswa zvakanyanya chaizvo mukugadzirwa uye kushandiswa kwemitemo, asi kune zvimwe zvakasiyana-siyana:
- Kunze, zvakasiyana nemuvara: nitrofosca ndeye yose yakachena yebasa, zvishoma nezvishoma bhuruu, uye nitroammophoska inopenya.
- Nitroammophoska inowedzera kuwandisa, saka inofanira kuiswa 1.5 nguva shoma.
- Nitroammophoska inonyanya kukodzera zvirimwa zvinomera.
Uchishandisa nitrofoscas paunenge uchidyara zvirimwa zvemiti, haungatyi kukuvadza utano hwako, sezvo husina kana nitrate, saka unowana kukohwa kwakanaka kwezvakatipoteredza.
