Ama-ciderate abizwa ngokuthi izitshalo ezincelisayo, ezicebisa ngenhlabathi ye-nitrogen, zithuthukise isakhiwo saso futhi zifaka isandla ekwandiseni ukukhula kokhula. Lokhu kuvumela ukusetshenziswa okuncane kwamanyolo amakhemikhali ukugcwalisa inhlabathi empofu. Ama- ciderates ezitshalo , ngokuvamile ekuqaleni kwentwasahlobo, ngaphambi kokutshala izitshalo eziyinhloko, noma ekwindla. Esikhathini esilandelayo, abalimi abaningi bangabaza ukuthi kunesidingo yini ukumba phezu kwezimbangi ebusika. Ake sibone.
Ingabe kuyadingeka ukumba phezu kwezimbangi ebusika?
Njengoba wazi, i-nitrojeni iqoqa eziqongweni kanye nezimpande zezitshalo - ziphazamisa. Lokhu kufaka isardadi, ama-oats, i-peas, i-rapeseed, i-clover, i-alfalfa nabanye abaningi. Izinto eziqoqiwe eziqongweni zingene enhlabathini echithiwe, futhi uhlelo oluyisipesheli lwe-branched luveza inhlabathi ingavamile. Ngokuvamile abalimi banquma "ukuncelisa" inhlabathi ngemva kokuvuna, ngasekupheleni kwehlobo noma ekwindla zakuqala. Kodwa isikhathi sidlula, futhi ngokusondela kwemakhaza ebusika, abanikazi abanomthwalo wemikhakha banombuzo wokuthi bangabopha yini. Empeleni, kunezimvo eziningana:
- Abaningi bakholelwa ukuthi ukumba kudingekile ukuze isitshalo sibheke phezulu. Ngemuva kokuqedwa kwemvelo, izinto eziwusizo ekugcineni ziyowela enhlabathini, zigcwalise. Futhi lokhu kuyiqiniso, uma sikhuluma ngokuthi ngabe udinga ukumba umasinara noma yimuphi omunye umkhuba wokubambisana.
- Kodwa, ngesikhathi esifanayo, lapho ukumba, kukhona ukuguqulwa kwezingxenye zomhlaba, ngenxa yokuthi ubuqotho besimiso sezimpande eziphazamisayo buphazamiseka. Ngenxa yalokho, i-nitrogen nezinto eziyigugu eziqoqiwe ezimpandeni azihlali emhlabathini, kodwa ziguquguquke.
Futhi-ke yini okufanele uyenze uma kukhona ukuphikisana okunjalo ukuthi udinga ukumba umhlabathi emva kokubambisana?
Ukusebenzisa i-flatbed ukumba
Abalimi abanolwazi abanokuhlangenwe nakho batusa ukusebenzisa ithuluzi le-horticultural elithakazelisayo - i- planar . I-shank yamapulangwe, ekugcineni kwayo, nge-bolts, isibhakabhaka sensimbi esicishe sibe seduze nama-angle angakwesokudla. Ngaphezu kwalokho, izindawo zalo ezintathu zibukhali kakhulu. I-cutter ikuvumela ukuba uphathe inhlabathi ngokucophelela, kunokuba umfosholo noma i-hoe. Ngesikhathi esifanayo ukukhulula nokumba kwenhlabathi nge-flat-top cutter kwenzeka ngaphandle kokuguqula inhlabathi ngokujula kwama-5-7 cm. Ngesikhathi esifanayo, imifino yezingxube ziwela emhlabathini. Into esemqoka ukwenza lokhu ngaphambi kokuthi iziqongo zikhule ngaphezu kwe-10-15 cm ukuphakama. Yonke impendulo ekucabangeni ukuthi ngabe udinga ukumba, uthi, i-oats noma i-rye njenge-siderat ekwindla.
