Akubona njalo abalimi beqonda ukuthi yiziphi izitshalo zomanyolo ezenzelwe, nini futhi hlobo luni lwazo okufanele zisetshenziswe. Futhi lokhu kubaluleke kakhulu ukwazi, ngoba uma wenza ukuba bashintshe ukwakheka kwenhlabathi lapho isitshalo sithola umsoco wayo, okwenza kube khona ukuthuthukiswa kwayo.
Manje akuyona inkinga yokuthenga umanyolo, kodwa ukuze wenze ukukhetha okulungile, udinga ukwazi ukuthi yilowo nalowo kubo uhloselwe. Kusukela kulesi sihloko uzothola mayelana nokusetshenziswa kwe-phosphorus-potassium (noma i-potassium-phosphorus fertilizer) yokutshala izimbali nezitshalo zemifino.
Iyini umanyolo we-phosphate-potassium?
Lokhu kuyinkimbinkimbi yokufaka umquba wamaminerali, izakhi eziyinhloko zazo eziyi-phosphorus ne-potassium. Manje kunenqwaba yezidakamizwa eziseli qembu, kodwa zihlukile kumaphesenti wezingxenye ezisemqoka negama lezici ezengeziwe.
Lezo zimila ezihlukahlukene ziyakuthandwa kakhulu ngenxa yokuthi ziqukethe izinto ezimbalwa eziholela ekunakekelweni kwe-salinization yomhlaba.
Izinhlobo eziyinhloko zamaminerali e-phosphate-potassium
Ukuze siqonde kangcono ukuthi kungani kusetshenziselwa umquba we-phosphate-potassium, ake sicabangele izici zezinye zezinhlobo zazo.
Umanyolo we-Phosphoric-potash "I-autumn" . Ihlanganisa:
- ama-phosphates -5%;
- i-potassium - i-18%;
- i-calcium - 8%;
- i-magnesium - 2.5%;
- boron - 0,2%.
Kunconywa ukuthi usebenzise izitshalo zensimu, zokuhlobisa nezitshalo ngezikhathi ezilandelayo:
- uma umba - ekwindla 35-60 g / m & sup2 noma entwasahlobo, kodwa kakade kanye kanye nokulungiselela okune-nitrogen;
- ngesikhathi sezimbali futhi ngesikhathi sokuhluma, yenza u-15-30 g / m & sup2 isikhathi ngasinye lapho uhlunga futhi ukhulula inhlabathi, khona-ke kufanele kuphuziswa;
- ekupheleni komjikelezo wezitshalo - cishe ngo-Septhemba ngomthamo we-30-40 g / m2 sup2. Lokhu kuyadingeka ukuze ubusika obuphumelelayo nokuvuthwa kwamahlumela.
I-Nitrofosca. Ekubunjweni kwayo kufakwe amasheya alinganisiwe (12% ngayinye) i-potassium, i-phosphorus ne-nitrogen, esezingeni elilula lokugaya, ngakho-ke zonke izinto eziwusizo zingena esitshalweni. Ikhiqizwa ngendlela yama-granules ama-gray nge-tinge e-pinkish. Umthamo wesicelo ovumelekile ungama-45-60 g ngehora le-1 m & sup2. Kunconywa ukuthi uyisebenzise ngaphambi kokuhlwanyela imbewu (ngokwethenjelwa ekuqaleni kwentwasahlobo) nasezinyangeni zasehlobo.
I-nitroammophoska. Iqukethe i-phosphorus, i-nitrogen ne-potassium, i-17% ne-2% isulfure. Yethula kunoma yiluphi uhlobo lomhlabathi 40-50 g per m & sup2 entwasahlobo uma itshalwe, njengomanyolo omkhulu, kanti ehlobo njengama-fertilizer engeziwe.
Ama-nitrophos . Iqukethe:
- 6% i-nitrogen;
- I-calcium engu-11%;
- 16% i-phosphorus.
Perfect for ukufaka umquba for izimbali eziningi zensimu.
I-Diammofosca. Iqukethe nitrogen (10%), i-potassium (26%), i-phosphorus (26%), kanye nenani elincane lensimbi, i-calcium, i-zinc, i-magnesium nesulfure. It isetshenziswa 20-30 g per 1 m & sup2. Kunconywa ukusebenzisa cishe yonke imibala.
I-Carboammofosca. Isakhiwo sihlanganisa:
- i-nitrogen 14-24%;
- i-phosphorus pentoxide 12-21%;
- I-K2O-12-16%.
Yenzelwe ukufaka umhlabathi ngaphambi kokuhlwanyela.
Umanyolo we-Phosphate-potash "AVA" . Isici esikhethekile salesi simiso sokukhiqiza umanyolo ukuthi asiqukethe i-nitrogen, futhi sisezidakamizwa ezinomswakama.
Ungasebenzisa umanyolo ngaphambi kokuhlwanyela imbewu. Kunezindlela eziningana zokwenza lokhu:
- ukufaka inoculum;
- ukutshala noma ukuxuba imbewu;
- ukuthululela inhlabathi ngesisombululo salesi sidakamizwa.
Uma ufuna ukusebenzisa umanyolo wemvelo, ungasebenzisa izinkuni zokhuni , okubhekwa njengokudla okunzima, njengoba kuqukethe izinto eziningana ezibalulekile, kuhlanganise ne-potassium ne-phosphorus. Izinga lokufaka isicelo eliphakanyisiwe yizingqimba ezingu-3 nge-1 m & sup2.
