I-95% yeDichloropropene: Ukucoca Okunzulu Umhlaba Wakho

I. Ukugxila ekulweni "nababulali abangabonakaliyo bomhlaba"

Phakathi kwezinambuzane ezahlukeneyo ezithwalwa ngumhlaba, iingcambu ze-nematodes zezona zibangela ingxaki.

Zincinci ngobukhulu, zifihla nzulu emhlabeni, zihlasela iingcambu zezityalo, zenze amaqhuqhuva (iingcambu) avala imijelo yokuthutha amanzi kunye nezondlo.

Izityalo ezichaphazelekileyo zihlala zibonakala “zingondlekanga,” zinamagqabi atyheli nabunayo; xa zijongwa kakuhle, iingcambu zimfutshane, zinqabile, kwaye zigqunywe ngamaqhina.

Umsebenzi we-95% dichloropropene kukwenza "ukucoca" kube kanye ii-nematodes, ezinye iifungi, kunye nembewu yokhula emhlabeni ngaphambi kokutyala ngokusebenzisa i-fumigation yomhlaba.

Umgaqo wayo awunzima: emva kokuba iarhente isetyenzisiwe emhlabeni, iyatshintsha ibe yigesi kwindawo evaliweyo, isasazeke kuyo yonke imingxunya emincinci yomhlaba kwaye isebenze ngokuthe ngqo kwinkqubo yokuphefumla yezinto eziphilayo eziyingozi, ngaloo ndlela ifezekisa umphumo wokubulala.

Ngamafutshane, itshiza “izinto ezimbi” emhlabeni ngegesi, inika izityalo indawo ecocekileyo yokukhula kweengcambu.

II. Kuthetha ukuthini ukuba ne-95% High Concentration?

Xa kusenziwa, ukufunxa umhlaba ngedosi ecetyiswayo kunokufikelela kwi-90% yokulawula ukusebenza kakuhle ngokuchasene ne-root-knot nematodes kwijinja,

kwaye ibonisa ukusebenza okugqwesileyo okufanayo ngokuchasene ne-root-knot nematodes kwizityalo ezifana neekhukhamba kunye neetumato.

Kwintsimi ezifunxwe yi-fungi, iinkqubo zeengcambu zezityalo ziphuhliswe kakhulu, zineengcambu ezimhlophe ngakumbi, nto leyo ebangela ukukhula kwezityalo okunamandla kunye nexesha lokuvuna elandisiweyo.

III. Indlela yokuyisebenzisa

1. Ukulungiswa Komhlaba: Okokuqala, susa amasalela ezityalo kwisityalo sangaphambili, uhlakule nzulu, uhrule, uze ulinganise umhlaba,

ukugcina umgangatho womswakama womhlaba ungama-60%-70% (okungcono kukuba, kufuneka ihlangane xa icinezelwe ngesandla kodwa iqhekeke lula xa iwisiwe).

Oku kwenza kube lula ukusasazwa ngokulinganayo kwesibulali-zinambuzane.

2. Ukusetyenziswa: Nciphisa isibulali-zinambuzane ngamanzi ngokwemilinganiselo ecetyiswayo uze usitshize ngokulinganayo kumphezulu womhlaba usebenzisa isitshizi esenziwe ngesandla okanye ngenjini.

Emva nje kokuyifaka, sebenzisa i-rotary tiller okanye i-hoe ukuze udibanise i-pesticide ngokulinganayo nomhlaba ongaphezulu we-15-20 cm, ukuqinisekisa ukuba idibana ngokupheleleyo nendawo ekujoliswe kuyo.

3. Ukufihla kunye nokutywina:

Eli lelona nyathelo libaluleke kakhulu. Emva kokufaka isibulali-zinambuzane nokusixuba emhlabeni, gquma umhlaba ngoko nangoko nge-mulch (kungcono ubuncinane ubukhulu obuyi-0.04 mm),

uze uvale imiphetho ngomhlaba, ungashiyi zikhewu. Ukucoca nge-fumigation kudla ngokuthatha iintsuku ezisi-7-15 (ubude bexesha buxhomekeke kubushushu bomhlaba kunye nokufuma; amaqondo obushushu aphezulu adinga ixesha elincinci).

4. Ukususa i-mulch ukuze kungene umoya: Emva kokufutha, susa i-mulch uze uyikhulule umhlaba kwakhona ukuze uvumele iigesi eziseleyo ziphele ngokupheleleyo.

Eli nyathelo libizwa ngokuba “lixesha lokungenisa umoya,” elihlala lithatha iintsuku ezisi-7 ukuya kwezili-14, de ivumba elibonakalayo lesibulali-zinambuzane lingasabonakali. Emva kokungenisa umoya, ukuhlwayela okanye ukufakelwa izityalo ngendlela eqhelekileyo kungaqhubeka.

Ixesha lokufaka: Kungcono ukuqala inkqubo kwiintsuku ezingama-20-30 ngaphambi kokuhlwayela ukuze kubekho ixesha elaneleyo lokufaka i-fumigation kunye nokungenisa umoya, ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko.
