4. Ukuchumisa
Ukuchumisa kufuneka kufakwe kwizixa ezincinci kunye namaxesha amaninzi ukuqinisekisa ukukhula kwengca.
(1) isichumisi
Izichumisi ezihlanganisiweyo zahlulahlulwe zaza ezimbini: zinyibilikisiwe ngokukhawuleza, zezona zichumiso ziphambili zengca eluhlaza. I-therililitive ye-tirtili ichithwe emanzini kwaye itshizwe, ngelixa isichumisi esihamba kancinci sisasazeka ngokuthe ngqo. Nangona kunjalo, ukusetyenziswa kwesichumisi esihamba kancinci sihlala sibangela ukutshiswa kwendawo, ke kusetyenziswa kakhulu kwingca eluhlaza enemithetho enamavili ngeemfuno ezisezantsi.
② Area. I-Urea ingumchumisi ophezulu we-nitrogen kwaye ihlala isetyenziselwa ingca eluhlaza eluhlaza enezandla. Ukusetyenziswa kakhulu kwesichumisi kwi-nitrogen yesichumisi kwiGreen Gress Bulls kuya kubangela ukuba isifo sezityalo sinciphise kwaye sosuleleke. Uxinzelelo olungafanelekanga lunokubangela ngokulula, ke ngoko ayilungelanga ukusetyenziswa kakhulu.
Isichumisi se-nitrogen sineziphumo esifanayo kwi-Urea.
④ Isichumisi sexesha elide sisichumisi sisichumisi esiqinileyo se-swiltiment esinefuthe elinde kunye nesiphumo esihle. Ngokubanzi, akuyi kubakho phenomeno evuthayo, kodwa kuyabiza.
(2) ImigaqoUkukhetha isichumisi
I-Green Grey Isalathisa ngasentla Inqanaba loku-1 Sebenzisa isichumisi se-Traintil kunye ne-2 ye-2 kunye ne-3 ingca yengca isebenzisa isichumisi esihamba kancinci, kunye ne-4
(3) Indlela yokuchumisa
I-therililitive ye-theritibe ichithwe kwibhafu yebhafu yamanzi kuxinzelelo lwe-0.5%, kwaye emva koko yatshiza ngokulinganayo ngocofe uxinzelelo oluphezulu. Isixa semali esichumileyo singama-80º / kg.
② Emva kokuba entywila ngokutyibiliko kunye nomthamo ocacisiweyo, ukutshiza ngocofe uxinzelelo oluphezulu.
Ukusasazeka isichumisi sexesha elide ngokulinganayo ngesandla ngokwemithamo echaziweyo, kunye nokutshiza kwasekuqaleni ngaphambi nasemva kokuchumisa.
④ Dibanisa isichumisi esinyibilikisi esicothayo ngokulinganayo ngokulinganayo kwidosi ye-20G / ㎡.
⑤ Dilute urea ngamanzi ngokuxinana kwe-0.5%, kwaye tshiza nge-puni yoxinzelelo oluphezulu.
I-8rtilization yenziwa ngokwendlela yendawo, isiqwenga, kunye nendawo yokuqinisekisa ukufana.
(4) Umjikelo wokuchumisa
Umjikelo wokuchumisa ochumileyo wesichumisi sexesha elide simiselwa ngokwemiyalelo yezichumisi.
Iqela elikhethekileyo kunye nenqanaba lokuqala eliluhlaza eziluhlaza ezingafunekiyo kunye ne-derililifayitha yexesha elide kufuneka isebenzise isichumisi se-therilical yethutyana kube kanye ngenyanga.
③ Area usetyenziselwa kuphela ukuluhlaza kwimibhiyozo ephambili kunye nokuhlolwa, kwaye ukusetyenziswa kwayo kulawulwa ngokungqongqo ngamanye amaxesha.
④ Isichumisi esinyibilikayo sisetyenziswa kanye rhoqo kwiinyanga ezi-3 zebanga lesibini lenqanaba lesibini nelesithathuingca eluhlazaI-Lawns.
