Iziqhamo ezininzi zegadi zizityebi kwizondlo, ingakumbi oku kubhekisela kumhlaba onomxholo omkhulu wesanti kunye ne-sandy loam. Ngenxa yezi zizathu, kufuneka kunikwe ingqalelo ekukhuliseni umhlaba.
I-potassium i-chloride yichumbo yemvelaphi yemvelo, ekhishwe kwi-potash ores. Ngako oko, musa ukwesaba umphumo wale nto, ngokuchaseneyo, ngokufanelekileyo kuphucula intle yesityalo esivunowe. Esi sichumiso sithandwa kakhulu yizambatho, iibhontshisi, iidroti, i-turnips, iidiliya.
Umanyolo we-potassium i-chloride - ukusetyenziswa kunye nomthamo
Ngokungathandabuzekiyo, ukugqoka okuphezulu kuthathwa njengeyona nto ifanelekileyo kwizityalo zemifuno, kodwa ngenxa yobukho be-chlorine, ezi zilandelayo ziphumo kufuneka ziqwalaselwe:
- i-chlorine, ukuqokelela ngokukhawuleza, inokunyusa i-acidity yomhlaba;
- I-potassium i-chloride ngokusetyenziswa kwexesha elide iyakwazi ukugcina ityuwa emhlabeni.
Ingqalelo kufuneka ihlawulwe kumxholo we-chlorine kwi-potassium i-chloride, ifom yesicelo sokuthi ihlehliselwe ixesha lokubumba, ukwenzela ukuba isakhi seklorine sinokuhlamba emhlabathini ekwindla nasebusika.
Kodwa ngaphandle kwesi sichumiso asikwazi ukuyenza emhlabathini, equkethe inani elikhulu le-peat eyomileyo, isanti kunye ne-sandy loam. Ukuze ungagqithiseli umhlaba nge potassium, umntu makayithobele ingqalelo kwiimeko zezityalo:
- xa amaqabunga alahlekelwa yi-chlorophyll ngokukhawuleza asomile, agutyungelwe ngamabala anobundu, i-skukozhivayutsya kwaye ajikeleze;
- Iziqu ziba buthathaka, ziguqulwa kwaye zingabonakali ngokungaqhelekanga;
- iyancibilikisa isiqhamo, ayikuvuthwa ixesha elide.
Ngaphambi kokusebenzisa isichumisi se-potassium chloride kwintsimi yemifuno, kufuneka ufunde ngokucophelela imiyalelo ukuze ungadluli kunye nomyinge. Umanyolo usetyenziswa ngolu hlobo:
- Ekwindla kuyimfuneko ukunyusa umhlaba kumlinganiselo we-100-200 g wezinto nganye kwi-10 metres square. m yomhlaba. Umhlaba ochithwe ngokukodwa unako ukutyalwa kwintwasahlobo, kodwa nakwi-20-35 g nganye kwi-square. m;
- Iifomatiyiti ze potassium eziyinkimbinkimbi, ngenxa yobuncinane bomxholo we-klorine, zisetyenziselwa ngqo kwimithombo ngaphambi kokutyala ngokumalunga no-20 g kwi-1 sq. Km. m;
- Ukusetyenziswa kwe-chloride ye-potassium granulated kwenziwa ngokuxuba umhlaba omanzi kunye nama-granules. Inomhlaba ixesha elide ukuba libe semhlabeni, ngoko ke unako ukutyalwa ingcambu kangako. Ngokuqhelekileyo kusetyenziswa i-potassium chloride, idibene ne-nitrogen kunye ne-phosphate. Oku kunceda ukukhawuleza uphuhliso lwezityalo.
Ukuhlawula ngokukhethekileyo izilumkiso, sebenzisa iiglavu zegadi kunye nokuphefumula. Imveliso esekelwe kwiPotassium ayifanele ixutywe kunye nechoki, i-dolomite kunye ne-lime.
Ukusetyenziswa kwesichumisi se-potassium i-chloride akuyona inkqubo enzima kwaye ibuhlungu, kodwa kufuneka iphathwe ngqalelo, iqwalasele iimeko zesicelo.
