Cov tswv yim siv thev naus laus zis ntawm cov chaw tsim tshuaj tua kab hauv cov orchards
Weeding nyob rau hauv orchards yog nyuaj vim muaj ntau yam txiv hmab txiv ntoo seedlings, lub sij hawm sib txawv ntawm kev loj hlob ntawm tib lub seedlings, thiab sib txawv tshwm sim ntawm cov nroj tsuag. Nyob rau sab qaum teb, muaj ntau lub txiv apples, txiv hmab txiv ntoo, txiv duaj, kiwi thiab walnut orchards.
Cov yam ntxwv ntawm orchard cog yog tias cov nroj tsuag kab sib nrug loj, thiab nws yog ib qho yooj yim mus siv tshuaj nyob rau hauv hav zoov. Ua ntej xyoo 2016, feem ntau ntawm cov tshuaj tua kab mob tau siv rau cov nroj tsuag (lub npe hauv tsev yog paraquat), uas yog cov tshuaj tua kab mob sai sai nrog kev sib cuag thiab qee yam cuam tshuam. Dav dav, cov ntaub so ntswg ntsuab ntawm cov nroj tsuag pib raug kev puas tsuaj thiab nqus tsis pub dhau 2-3 teev tom qab siv cov tshuaj, thiab lawv tuag hauv ob peb hnub. Cov neeg tsim tshuaj tua kab mob tsis muaj txiaj ntsig rau cov ntaub so ntswg uas tsis yog ntsuab, thiab ua ke sai sai nrog cov av hauv cov av thiab passivated, thiab tsis muaj txiaj ntsig rau cov hauv paus hniav, perennial underground stems thiab perennial keeb kwm. Paraquat yog tshuaj lom rau tib neeg, thiab tsis muaj tshuaj tua kab mob tshwj xeeb.
Nrog rau qhov tshwm sim ntawm glufosinate-ammonium, qhov teeb meem no tau daws. Glufosinate yog hom kev sib cuag dav dav, ib nrab lossis tsis muaj zog thiab tsis muaj kev sib cuag-tua tshuaj tua kab. Glufosinate ua ntej tua cov nplooj, thiab nws txoj kev ua haujlwm sai yog nyob nruab nrab ntawm paraquat thiab glyphosate. Ntawm qhov tod tes, ntau cov nroj tsuag muaj rhiab heev rau glufosinate thiab tuaj yeem siv hloov pauv hauv thaj chaw uas glyphosate tiv taus, tab sis glufosinate yog kim thiab tswj tsis tau cov cag ntoo.
