Kutheni sikhetha iYunnan njengesiseko sethu sokutyala?
IYunnan, eyaziwa njengeyona ndawo iphambili yokutyala iirozi eTshayina, ifumana iwonga layo elibekekileyo kwizinto ezininzi ezibalulekileyo. Okokuqala, iimeko zayo zemozulu zibonelela ngemekobume efanelekileyo yokulima iirozi. Ibekwe ekudibaneni kweendawo ezishushu kunye neendawo ezitshisayo, iYunnan yonwabela imozulu efudumeleyo nefumileyo, ukukhanya kwelanga okuninzi, kunye nemvula efanelekileyo, konke oku kudala iimeko ezifanelekileyo zokukhula kweerozi.
Ngaphaya koko, iimeko zomhlaba eYunnan zidlala indima ebalulekileyo ekulinyweni kweerozi. Umhlaba walo mmandla utyebile kwiiminerali kunye ne-organic matter, enempembelelo enkulu ekukhuleni nasekudubuleni iirozi, ngaloo ndlela inegalelo ekunyakazeleni nasekuqineni kweentyatyambo.
Iimpawu zejografi yeYunnan, kubandakanya intaba kunye nokuphakama okuphakathi, kuphucula ngakumbi ukufaneleka kwayo njengesiseko sokutyala iirozi. Ezi mpawu zendalo zikhuthaza imekobume ekhuthaza ukukhula kweerozi, nto leyo ebangela ukuba iintyatyambo zikhule ngakumbi nezinemibala engakumbi.
Ngaphaya koko, imbali kaYunnan ebanzi yokutyala iirozi ikhokelele ekuqokeleleni amava atyebileyo kunye nobuchule bemveli phakathi kwamafama asekuhlaleni. Obu butyebi bolwazi kunye nobuchule bubenza bakwazi ukukhulisa ngokufanelekileyo ukukhula kweerozi, besomeleza ngakumbi isimo sikaYunnan njengenkulumbuso isiseko sokutyala iirozi eTshayina.
Ukuqukumbela, indibaniselwano eyodwa yeYunnan yeemeko zemozulu ezivumayo, umhlaba otyebileyo, imbonakalo yejografi, kunye neendlela zemveli zokutyala ziyimisele njengeyona ndawo ifanelekileyo yokulima iirozi eTshayina. Ezi zinto ngokudibeneyo zinegalelo kudumo lukaYunnan njengenkulumbuso isiseko sokutyala iirozi, nto leyo eyenza ibe liziko elibalulekileyo lokukhula kunye nokongiwa kwezi ntyatyambo zintle.
