I-Zinc ingumkhondo wokuhamba-hamba ngokusisiseko sokugcina ukukhula kwemithi yeziqhamo. Kwisityalo somthi weziqhamo, ukusetyenziswa kwe-zul sulfate engayinciphisi kuphela ukusilela kwimithi yeziqhamo, kodwa kwandisa isiqhamo somthi weziqhamo.
Iimpawu zokunqongophala kwe-zinc kwimithi yeziqhamo: Imithi yeziqhamo enesiziri idla ngokubonisa i-internoded i-goones, ineentyatyambo ezincinci, kunye neziqhamo ezincinci, ezisemgangathweni, nokufa komthi wonke umthi.
Njengoko iminyaka kunye nokuveliswa kwemithi yeziqhamo kunyuka, iimfuno zeZinc imithi yeziqhamo iyanda, ngakumbi kwiilwandle zesanti, i-saline-alkali imihlaba enolawulo olubanzi.
Ukujongana neempawu zokunqongophala kwe-zinc kwimithi yeziqhamo, manyathelo alandelayo anokuthathwa:
1. Faka isichumisi se-zinc umhlaba. Zidityaniswe nesicelo sesikhuselo sesiseko kunye ne-fincrilizer, ngokubanzi i-100-200 yemithi nganye kwimithi yeziqhamo eneminyaka emi-7 ubudala, kunye neegram ezingama-250-300 zomthi ngamnye oneminyaka eli-10 ubudala okanye ngaphezulu.
I-2. Spray Sinc sulfate ngaphandle kweengcambu. Phambi kokuba imithi yeziqhamo ihluma, i-spray 1 ~ 5% ye-Zinc Sulfate kuyo yonke imithi, i-spray 0.1 ~ 0.4% i-Inc Sulfate emva kokuba iphumelele i-0.3% urea ukufikelela iziphumo ezigqwesileyo.
3. Spuray Zinc Ash Alter. Umyinge wezixhobo ezifunekiyo yi-zulc ye-zulc sulfate: I-Quightlime: Amanzi = 1: 2: 240, kwaye indlela yoqwalaselo ngumxube we-bordquaux.
