Sezvo kushomeka kwemvura kuri kuwedzera, vesaenzi pasirese vari kutarisa sarudzo dzevarimi dzediridziro nzira.
Heano matatu ezvidzidzo nezvimwe zvinonakidza mhedzisiro.
Mashandisiro anoita Kusamanikidza Kudiridza muMunda Kugadzira Kunoderedza Zvinowanikwa
Vanotsvaga vakatanga kutsvaga kuti nzira nyowani yekudiridza inofananidzwa nenzira dzazvino dzeindasitiri yemadiridziro. Negative Pressure Irrigation (NPI), kudiridza kwepasi maitiro, anga aine kutarisisa kwakawanda nguva pfupi yadarika. Ino vimbisa kudzikisira zvishandiso, zvese mvura uye kubereka.
Mamwe mabhenefiti anozivikanwa eNPI ndeyekuti inopa kudiridza kunoenderana nekushandisa kwechirimwa mvura yevhu,
uye inochengetedza mvura yemuvhu kugadzikana munguva yekukura kwezvirimwa.
Asi zvinokanganisa sei kukura kwezvirimwa uye goho?
Chikwata chepasi rose chinobva kuChina, Belgium, neUS chakafananidza kuti cucumber (container yakarimwa sei) nemadomasi emumunda zvaifamba sei nemhando dzakasiyana dzemadiridziro.
Chikamu checucumber chekudzidza chakakonzera gohwo repamusoro. Kune vakawanda varimi vemiriwo, zvakadaro, mhedzisiro yenyaya yemadomasi iyo inobata zvakanyanya kufarira. Chikwata chakafananidza NPI neforo uye kudonha kudiridza.
Vakawana NPI yakaderedza mafetiraiza uye zvekudiridzira kana zvichienzaniswa neyese yemadiridziro nemadiridziro. Kunyangwe pakange pasina kuwedzera kwakakosha mukukohwa, kana kwaiveko
kuderera.

Munyu Akawanda Sei?
Nekuwanika kwemvura kuri munjodzi, vaongorori vari kunyatso tarisa zvinoitika kune zvirimwa zvine mvura yemhando yepamusoro yemadiridziro uye nemvura yakadzikira.
Mvura yebrackish inogona kukanganisa mamiriro ekukura kwezvirimwa, asi panguva ipi inozokuvadza? Uye kusvika papi varimi vanogona kusundira kudzikisa mwero wemadiridziro michero isati yatambura?
Vatsvagiri veBrazil vakadzidza nezvekuti makorodhi akanganiswa sei nematanho mashanu akasiyana evhu conductivity (munyu), imwe neimwe ichishandiswa pamatanho mana akasiyana ekudiridza (55%, 70%, 85%, uye 100%).
Masayendisiti echirimwa akasarudza makorodhi sezvo akaumbwa nemakumi mapfumbamwe emakumi emvura uye acharatidza kukonzeresa ekudiridza nekukasira.
Dare rekutsvagisa rakashandisa nzira dzinoverengeka dzekuongorora mhedzisiro: kukwirira kwemiti, dhayamita yehunde, huwandu hwemashizha, biomass (yakaoma uye nyowani), uye green color index.
Nematanho akawanda, chidzidzo chine mhedzisiro yakaoma. Pakazara, madiridziro akange aine simba rakakura pane goho uye mhando kupfuura munyu. Brackish mvura inogona kunge iri sarudzo kana madanho ekudzora asina kukwirira zvakanyanya.

Mycorrhizae Inotendera Zvepasi Zvishandiso
Chikwata chekuBrazil / cheSpanish chakatsvaga chakaedza katatu kuti chione kana mycorrhizae pakudiridza kwakaderera nemamiriro efetiraiza zvinokanganisa goho remuriwo.
Pamuedzo wega wega, timu yakamera madomasi muvhu isina tembiricha yekudziya mugreenhouse muNorth Spain.
Chidzidzo chekutanga chakaderedza madosi efetiraiza kumiti yemadomasi akaiswa jekiseni nemycorrhizae. Nhamba yemichero, goho rese, uye mhando yemichero yakawedzera.
Yechipiri yakayedza madiridziro ezinga nemadomasi akaomeswa - akajairwa epurazi, 75% yeavo mazinga, uye chirongwa chakadiridzwa chemadiridziro chinoenderana nemamiriro ekunze nedata rekukura kwezvirimwa. Dhefisiti uye yakagadziridzwa kudiridzira yakawedzera goho uye saizi yemichero asi kwete michero-inogadzikana yakasungwa yakasimba kana ruvara. Pakanga pasina mhedzisiro kubva ku mycorrhizae inoculation.
Kweyechitatu kuyedza, ivo vaongorori vakadzora kubereka nekugadzirisa madiridziro emadhizai zvichienderana nedata remvura. Miti yakavharirwa yakasimbisa goho rezvikamu zvine gumi nematatu muzana emvura yakadzika uye huwandu hwefetiraiza, timu inoshuma. Izvo zvinoenzana ne13% kuderera kwemutengo, uko vanoongorora vanoverengeka zvakapetwa katanhatu kupfuura mutengo weiyo inoculation.
