1. Inorganic impurities in water
Vegetable zokugcina zisebenzisa drip irrigation eyenzeka, iningi amanzi amanzi kahle. Kuyaqondakala ukuthi ukuvela ephezulu ukugeleza mgodi kala, futhi ezinye imithombo ukusetshenziswa kwesikhathi esithile ngemva isimo uzobe ubishi. Amanzi isihlabathi futhi amatshe okuqukethwe ukwanda, ngeke izimbobo ngenkasa ukuvuza ngokungangabazeki ukuvuza kubangelwa wokufaka. Kwezinye izindawo ocebile kwemithombo yamanzi emhlabathini, drip irrigation eyenzeka ikakhulukazi amanzi ngaphakathi emseleni, okuyinto iqukethe obungafani obuningi ezisukela ukungcola wezinto ezingaphili. Lezi zivimba isigebengu.
Solutions: Ukuze ukungcola wezinto ezingaphili amanzi ngaphezulu, ukuvimbela wokufaka kufanele kuqinise ukuhlunga amanzi. Ngo amanzi ngesikhathi ukufakwa emikhulu imishini filtration, e-greenhouse ngamunye abalimi udinga ukufaka ekusebenzeni eqinile uhlelo monomer filtration. Ezinjalo njengoba isihlabathi futhi amatshe lemifanekiso, laminated, anezikhala isihlungi inhlanganisela, izinga lamanzi bungatholakala usebenzisa indinganiso drip irrigation eyenzeka. Uma kutholakala ukuthi uvimba isimo ezenzeka esikhathini imbobo ipulaki ngembobo ngesikhathi esifanayo, kufanele uvule i-capillary yokuthuthukisa ingcindezi amanzi ukuhlanza amanyela emkhandweni capillary.

2. Organic impurities
Ukuze ezinye umquba zamakhemikhali noma nezinye izinto okunobuthi imithombo engajulile noma emfuleni okugqoma, ukungcola organic emanzini ingenye yezizathu kubangelwa ekuvimbeni amehlo. Ngaphezu kwalokho, uma ukusetshenziswa se drip irrigation eyenzeka inqubo, umanyolo alisetshenziswa emva kokuphothulwa ezanele amanzi hashaza, kalula nje ingabangela ezihlukahlukene ulwelwe iphayiphi inqwaba zizalela, okuyinto uvimbela emehlweni esinye sezizathu .
Solutions: ukhethe izinga ezinhle drip irrigation eyenzeka ipayipi, ukuthatha black ifilimu ngaphansi kokulawula ngenkasa ngaphansi ifilimu. Kunezindlela ezimbili ukuxazulula amehlo sokuvimba Okokuqala, ukusetshenziswa acid ukuhlanza, magciwane bungatholakala, okusithiyayo nokuqeda ulwelwe nomphumela microbial yamanzi. Yandise esetshenziswa perchloric acid, nitric acid, wali band acid, i-sulfuric acid, sebenzisa inani pH kuya 5.5-6.0, ukwelashwa kufanele kube lilawulwa okuhlushwa, ukugwema umonakalo izitshalo. Acid wokuhlanza unaka ukwehlisa ingcindezi isimiso sokunisela ngenkasa ukubambezela ukugeleza rate futhi sithuthukise ukusebenza pickling, ngemuva kokuphela hashaza ngamanzi. Eyesibili ukusetshenziswa ezikhethekile inzalo algicide hashaza.

3. Amanzi nomanyolo
Sebenzisa se drip irrigation eyenzeka Umanyolo lapho Umanyolo uma solubility akuyona ukungcola ngokwanele noma ngaphezulu, kuzobangela ekuvimbeni amehlo. Nokho, abalimi yemifino futhi kudingeka ukuba banake inkinga ukuthi isetshenziswa kwezinye izindawo zokukhiqiza yemifino komhlaba, i-calcium, magnesium kanye nokunye okuqukethwe ion metal kuphezulu, okuqukethwe carbonate kuphezulu, ngokuvamile bathi ikhwalithi lamanzi kuqhathaniswa kanzima, ukusetshenziswa isikhathi eside Ukuconsa ngenkasa ipayipi odongeni ukukhiqiza isikali ngaphezulu (calcium carbonate, njll). Kwangathi futhi ixubene umquba wamakhemikhali lapho kwezulu kuzokwenzeka, okuholela ekuvimbeni amehlo.
Solutions: Ukuze izinga amanzi ezindaweni okunzima ingasetshenziswa ion amanzi exchange purifier for ukwelashwa amanzi. Ukuze uvimbele okuvela zikamanyolo uvimba emehlweni isimo, abalimi kufanele usebenzise izinga ezinhle, solubility okusezingeni eliphezulu, akukho Umanyolo amanzi-encibilikayo asalile. Manje nge ngcono amanzi-encibilikayo Umanyolo yokukhiqiza inqubo, ukusetshenziswa ion kusebenze ubuchwepheshe emanzini encibilikayo Umanyolo izakhi more uzinze, singavimbela ion Umanyolo namanzi metal kubonise kwezulu.
