I-Citrus, isityalo sosapho lwe-Arantioideae kusapho lwe-Rutaceae, sesinye sezona zityalo zemali zibalulekileyo ehlabathini, ezibalelwa kwikota yeziqhamo zehlabathi zizonke. Zininzi iindidi zesitrasi, eziquka isitrasi esinamaxolo abanzi, iorenji, ipomelo, igrapefruit, ilamuni kunye nelamuni. Kumazwe angaphezu kwama-140 kunye nemimandla, kuquka iChina, iBrazil kunye ne-United States, indawo yokutyala i-citrus yafikelela kwi-10.5530 yezigidi ze-hm2, kwaye isiphumo sasiyi-166.3030 yezigidi zeetoni. I-China lelona lizwe likhulu lemveliso yesitrasi kunye nelizwe lokuthengisa, kwiminyaka yakutshanje, indawo yokutyala kunye nemveliso iyaqhubeka ikhula, ngo-2022, indawo emalunga ne-3,033,500 hm2, imveliso ye-6,039 yezigidi zeetoni. Nangona kunjalo, ishishini le-citrus laseTshayina likhulu kodwa alinamandla, kwaye i-United States neBrazil kunye namanye amazwe anesithuba esikhulu.
ICitrus ngumthi weziqhamo oneyona ndawo yolinywa kakhulu kunye neyona meko ibalulekileyo yezoqoqosho kumazantsi eTshayina, enentsingiselo ekhethekileyo yokuphelisa intlupheko kumashishini kunye nokuvuselelwa kwamaphandle. Ngokuphuculwa kokhuseleko lokusingqongileyo kunye nokwazisa ngempilo kunye nophuhliso lwezizwe ngezizwe kunye nokwazisa ishishini le-citrus, i-citrus eluhlaza kunye ne-organic citrus ngokuthe ngcembe iba yindawo eshushu ekusetyenzisweni kwabantu, kwaye imfuno yomgangatho ophezulu, eyahlukeneyo kunye nokubonelela ngokulinganayo ngonyaka iyaqhubeka. Nyusa. Nangona kunjalo, kwiminyaka yakutshanje, ishishini le-citrus laseTshayina lichatshazelwa yimiba yendalo (ubushushu, imvula, umgangatho womhlaba), iteknoloji yokuvelisa (iintlobo, iteknoloji yokulima, igalelo lezolimo) kunye nendlela yokulawula, kunye nezinye izinto, kukho iingxaki ezifana neentlobo ezilungileyo. kunye nokubi, amandla abuthathaka okuthintela izifo kunye nezitshabalalisi, ulwazi lophawu alunamandla, indlela yokulawula isemva kwaye ukuthengiswa kweziqhamo ngexesha lonyaka kunzima. Ukuze kukhuthazwe uphuhliso oluluhlaza kunye nomgangatho ophezulu weshishini le-citrus, kungxamisekile ukuqinisa uphando malunga nokuphuculwa kweentlobo ezahlukeneyo, umgaqo kunye nobuchwepheshe bokunciphisa umzimba kunye nokunciphisa iziyobisi, umgangatho kunye nokuphucula ukusebenza kakuhle. Izitshabalalisi zidlala indima ebalulekileyo kumjikelo wemveliso yesitrasi kwaye zichaphazela ngokuthe ngqo isivuno kunye nomgangatho wesitrasi. Kwiminyaka yakutshanje, ukukhethwa kwezibulali-zinambuzane kwimveliso ye-citrus eluhlaza kunomngeni ngakumbi ngenxa yemozulu embi kakhulu kunye nezinambuzane kunye nengca.
Uphando kwidathabheyisi yobhaliso lwe-pesticide ye-China Pesticide Information Network yafumanisa ukuba nge-24 ka-Agasti ka-2023, kwakukho iimveliso ze-pesticide eziyi-3,243 ezibhaliswe kwimeko esebenzayo kwi-citrus e-China.
