Zomwe Zimakhudza Mitundu Yophatikizana Ili ndi feteleza ndi Herbicide
Zida zophatikizana zomwe zili ndi feteleza ndi herbicide, zodziwika bwino ngati udzu-njala, zaletsedwa mwalamulo ku Canada . Madera ambiri kale anali ndi malamulo pa udzu kapena zakudya zodzikongoletsera, koma chisankho cha Health Canada chinabweretsa chiletso chogulitsidwa ndi kugwiritsidwa ntchito kwa kamodzi komwe kanali kotchuka. Ngakhale kuti eni eni nyumba ankakonda mankhwalawa, sikuli bwino kwambiri kusamalira kusamalira udzu.
Kuwaza ndi kupopera mankhwala a herbicide sikuyenera kuchitidwa nthawi yomweyo, zomwe zimapangitsa kuti mankhwalawa asagwiritsidwe ntchito molakwika.
Kodi Ndalama-N-Feed Ndi Chiyani?
Udzu wa nthiti ndi kuphatikiza feteleza ndi broadleaf herbicide yomwe nthawi zambiri imagwiritsidwa ntchito pakati pa nyengo ngati njira yogogoda namsongole ndi kudyetsa udzu mu ntchito yosavuta. Chiŵerengero cha feteleza chimasiyana, koma makina ambiri otchuka amagwiritsa ntchito feteleza yamchere osakaniza madzi omwe amachititsa kuti kukula kwakukulu kusakhudze kanthu kali konse ku thanzi labwino ndi mphamvu ya mbewu. Ndilo mlatho wopita ku china chotsatira. Ndipotu, nayitrogeni yambiri ingayambitse matenda a grub ndi matenda.
Udzu wa namsongole ndi pamene vuto limayamba. The herbicide ndi mtundu wopangidwa ndi ufa wobiriwira wotchedwa broadheaf herbicides omwe ali ndi 2,4-D, mecoprop, ndi dicamba. Mankhwalawa ndi otchuka chifukwa cha ntchito yake yoopsa pa udzu wobiriwira pamene udzu usanavulaze.
Nthanga zokhuta udzu zimagwira ntchito pamsongole, choncho ziyenera kukhala zoyenera kuti mankhwalawo agwire ntchito. Udzu uyenera kukhala wothira kuti phulusa la herbicide lisamamatire masamba. Nkofunikanso kuti mvula isanenedwe; simukufuna kusamba mankhwala mumsanawo musanachite ntchito yake.
Zinthu zofunikirazi zingapangitse kuti udzu wodya udye bwino komanso wovuta, zomwe zimayambitsa kugwiritsa ntchito molakwa.
Nchifukwa chiyani Nsima-n-Feed Inaletsedwa?
Lamulo lokhudza kugwiritsira ntchito udzu ku Canada limayambitsa zovuta zenizeni zogwiritsira ntchito mankhwala ophera tizilombo-makamaka zokhudzana ndi thanzi la nthawi yaitali, mobwerezabwereza kuwonetsetsa-ndikupita njira yowonjezereka. Pogwiritsa ntchito mankhwala ophera tizilombo, makamaka kwa ana, ziweto, amayi oyembekezera, ndi okalamba, udzu wodya udzu umangokhala ngati udzu.
Choyamba, kugwiritsa ntchito herbicide monga ntchito ya bulangeti sikofunikira. Zakudya zamsongole zimafalitsa herbicide mpaka kumapeto kwa udzu ngati pali namsongole kapena ayi. Zizolowezi zoterezi sizikugwirizana ndi kuyanjana ndi tizilombo toyambitsa matenda (IPM) ndi zina, njira zowonjezera zowonongera udzu. Kugwiritsira ntchito herbicide kumene palibe chofunika ndizovuta komanso zosakhala bwino.
Vuto lina lophatikizapo zinthu ziwirizi ndikuti kuthira udzu ndi kumera namsongole pa udzu ndi zochitika ziwiri zosiyana ndipo siziyenera kuphatikizidwa. Kuwaza udzu kuyenera kuchitika pakutsata chisamaliro chosankhika, pamene kuchotsa namsongole ndi njira yake yokha ndipo ikhoza kuchitidwa mosamala komanso mosamala kwambiri ndi kupopera mankhwala nthawi yonseyo.
Kotero Ndikutetezerani Bwanji Mavuto?
M'madera ena, kugwiritsa ntchito mankhwala osakaniza a herbicides osati kung'onong'onong'onong'ono-kunyozedwa, ndipo ngakhale kupopera mankhwala kumsongo si njira yabwino. Pulogalamu ya IPM yosavuta ikhoza kuthandizira, pamodzi ndi kayendedwe kabwino ka chisamaliro cha udzu. Mulimonsemo, tingagwiritse ntchito mkangano wamphamvu kuti tiyang'ane za udzu wa udzu. Kulamulira namsongole wamsongole kumatenga njira yowonjezera ya namsongole ndikuwona kukhalapo kwawo monga chizindikiro cha mavuto ena. Amsongole amamera pamene udzu umasinkhulidwa kapena woonda / wopanda banga. Pulogalamu yowonongeka yowonongeka ikhoza kuthandizira, komanso kukupula udzu pamtunda wa masentimita atatu kapena kuposa. Mafupa amathandiza kuti nthaka ikhale ndi calcium, choncho kuyesera kwa nthaka ndi mapulogalamu a calcium omwe amatsatira angakhale njira yochepetsera chiwerengero chawo. Potsirizira pake, kupereka zinthu zabwino kwambiri pakukula udzu ndi njira yabwino yothetsera namsongole .
