Sezvatinoziva tese, kugadziriswa kwetsvina yemudzimba kumaruwa kunofanirwa kubatanidzwa nemamiriro chaiwo ekugara kwevanhu kumaruwa kuti pave nenzira yemunzvimbo, uye panguva imwe chete pave nehurongwa hwakanaka hwekushandiswa kwezviwanikwa uye kudzora kusvibiswa. Kushandiswa kwetsvina yemudzimba kumaruwa mushure mekugadzirisa zvine mwero kunogona kuderedza mari inoshandiswa mukurapa tsvina, kudzokorodza zviwanikwa zvemvura yekurima nezvinhu zvenitrogen nephosphorus, uye kushandisa zvizere ivhu rekumaruwa uye kugona kuchenesa nharaunda. Nekuda kwekukurumidzira kwekuvandudza nharaunda yekumaruwa, kushandiswa kwetsvina yemudzimba kumaruwa kuchava chinangwa chenguva refu chekuvandudzwa kwetsvina yemudzimba.
Kushanda kwenzvimbo iyi kunofanirwa kukurumidza kubvisa mafungiro ekare
Parizvino, kurapwa kwetsvina kumaruwa muChina, kunyanya uchishandisa zvivakwa zvakabatana + nzira dzezvakatipoteredza, asi mashandiro ezvivakwa haana tariro. Dzimwe nzvimbo dzekurapa tsvina dziri mumaguta dzinonzi "miniaturization", mari yekuvaka, kushanda nekugadzirisa yakakwira, nzvimbo dzekumaruwa dzakaoma kugamuchira, asi dzakaregeredzawo kushandiswa kwezviwanikwa zvetsvina zvemumba kuchengetedza basa rekubereka ivhu. Nekuda kwehuwandu hushoma hwehupfumi hwekumaruwa netekinoroji, mabasa akawanda ekurapa tsvina, zvekuti nzvimbo zhinji dzenzvimbo dzekurapa, network yemapaipi haigone kuvaka, haigone kutenga, kushaya vashandi vane hunyanzvi uye vehunyanzvi vekutarisira. Mumamiriro ezvinhu aripo ekukurumidza kukura kwemaguta, kurapwa kwemvura yakasviba kumaruwa kunofanirwa kuderedza mari shoma senge zvivakwa nema network emapaipi, kubvisa kufunga kwepakutanga, uye kukurudzira nzira dzakachipa, dziri nyore kuchengetedza dzekurapa zvine mwero uye kushandiswa kwezviwanikwa.
Kushandiswa kwezviwanikwa kunosimbiswa mumitemo yekuburitsa zvinhu
Panyaya yemitemo yekuburitsa tsvina yemudzimba kumaruwa, mumakore achangopfuura, kurapwa kwakaringana uye kushandiswa kwezviwanikwa kwave kuchisimbiswa zvishoma nezvishoma mumitemo yekuburitsa tsvina. Zvichienderana nedata statistics, hwaro hwakajairika hwekushandisa mitemo yenzvimbo dzekurapa iGB18918-2002, asi muna 2019, Ministry of Ecology and Environment yakaburitsa "Gwaro reKugadzirira Matsananguriro Ekudzora Kusvibiswa kweMvura yeNzvimbo dzeKurapa Mvura Yakasviba Mudzimba (yeKuedza Kuitwa)" (Nzvimbo yeHofisi yeZvenharaunda Tsamba yeSoil 〔2019〕 Nhamba 403), iyo inokurudzira kusarudzwa kwakasarudzika kwenitrogen nephosphorus reseigh uye matekinoroji ekushandisa mvura yemugungwa. Mushure meizvozvo, mitemo mitsva yekuburitsa tsvina mumatunhu nemaguta yakaderedzawo zvinangwa zvavo. Kurapa kwakaringana kwetsvina yemudzimba kumaruwa kuri kusimbiswa uye kukurudzirwa kubva kumusoro kusvika pasi, zvichiisa hwaro hwekushandiswa kwezviwanikwa zvinotevera.
Kutungamira kweKushandiswa kweMarara muNharaunda
Nzvimbo dzemvura dzakagadzirwa pari zvino ndiyo tekinoroji inoshandiswa zvakanyanya mukurapa tsvina dzemumaruwa munzvimbo dzekumaruwa. Kushandiswa kwetsvina dzemumaruwa muChina kuchiri padanho rekugadzirisa tsvina dzemumaruwa, kugadzirisa dziva uye kuchenesa ivhu rezvakatipoteredza. Sezvo kusvibiswa kwevhu rekurima kusanganisira tsvina dzemumaruwa kwave chinhu chikuru chinokonzera kusvibiswa kwemumaruwa muChina, manejimendi yese yemadziva, kuderedza kusvibiswa kwenzvimbo, kudzivirira kusvibiswa kwenzvimbo, uye kugadzirisa zvakatipoteredza kuchava nzira yekuvandudza manejimendi yekutonga kusvibiswa kwenzvimbo dzekurima. Saizvozvowo, tsvina dzemumaruwa dzinofanira kushandisa zviwanikwa zvemunharaunda. Kusimbisa basa rekuchengetedza nharaunda dzekumaruwa kuburikidza nekushandura kwekugadzira, kusanganisa nzvimbo dzekurapa mvura yakasviba dzekumaruwa, idzo dzinongobva pakuderedza zviwanikwa, nekurima kudzokorodza, kuunza masisitimu ekurapa anoenderana nekurima, uye kupa basa rakazara kune mutemo, masisitimu ezvekurima pachawo anoshanda nenzira yekuti anogona kuderedza kuburitswa nekuburitswa kwetsvina.
Zviri pamusoro apa ndizvo zvese zviri muchinyorwa chino, zvimwe zvirimo ndapota teererai kuLiDing kuchengetedza nharaunda chinyorwa chinotevera goverai. Li Ding yave ichishanda mukutsvagisa nekugadzira, kuvaka nekushandisa michina yetsvina yekumaruwa yakabatana kwemakore gumi. Kuburikidza nekuvandudza tekinoroji nguva dzose, tinoedza kupa mupiro mudiki mukuvandudza nharaunda yevanhu. Chishandiso chekuchenesa tsvina yemhando yeLi Ding chinogona kushandiswa zvakanaka kunzvimbo zhinji dzekumaruwa dzakaparadzaniswa.
