HOL HOL: codsiga

ninkii beerta kasta oo isku dayaya in ay kor loo qaado tayada dalagyada ay, iyadoo la isticmaalayo dhammaan noocyada kala duwan ee Bacriminta. Maanta, ugu badan waa Karbamid ah (HOL) oo ka kooban cuntada organic iyo daro nafaqo ciidda iyo sidoo kale nitrogen-hodanka ah.

A yar oo taariikh

HOL First helay in 1773 by cilmiga Faransiis Hillaire Rouelle, laakiin kaliya tan iyo 1828 waxay bilaabeen inay soo saaraan synthetically. nitrogen wax ku ool ah Karbamid bacriminta (HOL) qaab saafi ah ka kooban ilaa 46% of nitrogen, kala diri ee biyaha at pH isku dheeli tiran oo aan sun dhirta iyo ciidda.

Form sii daayo

HOL (Karbamid) waxaa soo saaray qaabab kala duwan:

• In foomka of dhagaxyada yar baabi'inayo si tartiib ah ee ciidda iyo waxay ka difaacdaa ka damaysay of nitrogen. Waa ay fududahay in ay u khaldaan oo la bacrimin kale, oo ay ku jiraan organic.
• Foomka waxaa dheer oo kiniin L dahaarka leh kula xuub gaar ah, laga ilaaliyo kala diridda degdeg ah ee ciidda, taas oo ka hortagtaa dalagga ka soo ciidda iyo nitration.

Karbamid: codsiga

tijaabo Field muujiyo in isticmaalka HOL sida bacrimin pre-beeridda a ogolaan karo si fiican dhammaan noocyada kala duwan ee carrada iyo hoos cayn kasta oo dalagyada. Marka waxqabadka tani ma aha hab liita oo amooniyam iyo ammonium sulfate, iyo mararka qaarkood, tusaale ahaan, carradu Xiindaabinta-podsolic qoyaan ku filan iyo serozem waraabiyo, waxay bixisaa a doonee dalagga baradho beeraha iyo cuntada. Waxaa loo adeegsaday sida labiska a top for dalagga xilliga qaboobaha ee horraanta gu'ga, iyo dalagyada isku xigta iyo khudradda seeding degdeg ah si looga hortago khasaaro nitrogen by uumi of ammonia sameeyay intii lagu kala daatay ee Bacriminta. Wixii dhirta foliar talinayaa crystalline content biuret duwanaansho in 0.2-0.3%.

faa'iidooyinka

bacriminta nitrogen waxa uu leeyahay faa'iidooyin ka badan Bacriminta kale. HOL (Karbamid) si fiican u nuugo dhaqamada, iyo ka-fiirsashada sare (1% xal) dila dhirta iyo ma gubi caleemaha. Marka ballaarinta la nuugo unugyada caleen sida Britain oo dhan, iyo sidoo kale la nuugo karaa by kala daatay ee ka yar tallaabada of urease enzyme ama ammonia si ay u sameeyaan a transformations loop diamino walxaha nitrogenous. Si kastaba ha ahaatee, Franchise of ammonia free aaga xididka gaabisaa biqilka iyo shanta hablood, si aad u baahan tahay in aad u buuxa samaynta HOL in ay ciidda at beeridda ama si siman u qaybiso.

talooyinka

Ka hor inta sii dheer of HOL in ay ciidda si fiican talinayaa in ay ku daraan daro kale ama ciid qalalan. Marka si sax ah loo isticmaalo, HOL granular (Karbamid) waa bacrimin nitrogen aad u fiican. Waxaas oo dhan waa in sifooyinka wanaagsan jirka iyo sidoo kale content sare oo nitrogen in ay ka kooban mahad. Tan iyo markii ay suurto gal tahay in ay isticmaalaan ee ciidda kasta, iyo waxa ay leedahay saamayn togan ku koritaanka dalagga, baahida loo qabo in bacrimin this universal koraa la xilli kasta, iyo natiijada ka, wax soo saarka korodhka ay.
