Ukuze uthole isivuno esihle semifino, akwanele nje ukutshala imbewu emhlabathini. Kubalulekile futhi ukuba unakekele ukuhluma kwawo okuphumelelayo, ukudala izimo ezidingekayo ekuthuthukiseni izitshalo nezimila zazo. Ngaphandle kokwehlisa kwendabuko, ukukhuphuka nokwehla, iphuzu elibaluleke kakhulu ukubhujiswa kwezinambuzane, okuhlukile kwesitshalo ngasinye.
Ukuzenzekelayo le nqubo kuzokusiza idivaysi ekhethekile - sprayer. Le divayisi yokuphalaza okufanayo of insecticide, ukubulala ukhula, umquba wamanzi, njll Ukusebenzisa le nqubo kusebenza kakhulu kunokupuniza izitshalo ngesandla esidala, ngosizo lomshanelo. Ngaphezu kwalokho, amakhemikhali zanamuhla asho ukuthi, uma zicutshungulwa ngokucophelela yizo izitshalo nomhlabathi ozungezile, yenza kube lula ukulwa hhayi nezinambuzane kuphela, kodwa nokhula.
Izipulisi zinekhono futhi azikho amandla, futhi, kuye ngokuthi umthombo wamandla, zihlukaniswe zibe yi-petroli futhi kagesi. Ake sixoxe nge-motor-sprayers esebenza ngephethiloli.
Izici ze-sprayers kagesi
I-sprayer ye-petroli yegadi neyensimu ifakwe injini emibili yokushaya, isebenza ngendlela efanele yamafutha. Ngosizo lwedivayisi enjalo, ukucindezelwa kudalwa ebhodini, okudingekayo ukuphalaza amakhemikhali amanzi.
Uma uthenga, qaphela izici ezilandelayo zomkhiqizo owathengiwe:
- umthamo wethangi (kusuka ku-2 kuya ku-25 amalitha);
- indlela yokuqinisa (ama-knapsack noma amasondo);
- amathuba okusebenzisa amakhemikhali amakhemikhali nje kuphela, kodwa futhi ama powdery;
- umsebenzi wokuguqulwa kwengcindezi ngenxa yokutholakala kwesikhuseli seprayipi. Uma lolu khetho luhlinzekwa, ungakhetha iphethini eliphambili lokuphambanisa icala ngalinye (i-jet dense, i-mist enhle noma ukhethe into ephakathi);
- ubude be-hose spray (amamodeli ane tube
mfushane kunama-50 cm azikhululekile kakhulu ukubhekana nezindawo ezifinyelela kanzima).
Ukunakekela izitshalo nge sprayer engadini kuyinkqubo elula kakhulu. Ngomnikazi wendawo encane engama-acre angama-15, i-sprayer ye-knapsack iyoba yindlela enhle kakhulu, futhi kuyoba usizo kakhulu kumnikazi wesitshalo esikhulu ukuthenga uphethiloli wephethiloli kumavili noma imodeli ngebhethri.
Kulinganisweni yabakhiqizi bamapulisi e-knapsack e-petroli kanye namamodeli ezinamasondo, namuhla amafemu anjengoSadko, Stihl ("Shtil") aholayo. Okunye okuthandwa yi-Forte, i-Efco, i-Solo, i-Maruyama nabanye.
