Yokubulala ukhula ukhula: izinhlobo kanye nezindlela isenzo

Emvelweni, kunezinkulungwane izinhlobonhlobo ukhula yonyaka futhi zisetshenziswa. Lezi "ecasulayo" ikuyo yonke indawo wenze umncintiswano onzima kabi ukuba izitshalo, sibancisha umswakama, ukukhanya kanye nezakhi emhlabathini. Le ndlela evamile njengoba Ukuhlakula ukhula, akuzona njalo ngempumelelo e ukhula ekulweni, njengoba izinhlobo zisetshenziswa ngokushesha ziqhume enhlabathini izingxenye ezisele le rhizomes. Yingaleso sikhathi, futhi basisize we ukhula ukulawula ukhula.

Isenzo of yokubulala ukhula

Yokubulala ukhula - ekhethekile ikhemikhali senzelwe ukulawula
nokukhinyabezeka enanini lomsebenzi noma ekuvimbeleni ukukhula kokhula. Ngaphezu kwalokho, besebenzisa izingoma herbicidal kungenzeka ukunciphisa noma ngokuphelele ukuqeda ukutshala ibhukwana noma ngomshini, ngaleyo ndlela kuncishiswe umswakama ukulahleka iphinde ivimbele ukuguguleka kwenhlabathi. Yokubulala ukhula zihlukaniswe ngezigaba ezimbili - non-abakhethayo (isenzo esiqhubekayo) futhi uyakhetha (abakhethayo).

Yokubulala ukhula ukulawula ukhula nonselective

ukwakhiwa Herbicidal isenzo esiqhubekayo ngokungabi bikho ensimini osetshenziswayo
(Garden) izitshalo kutshalwa, njengoba bedla zonke izimila etholakalayo, engena phakathi iqabunga kwamanzi. Ngokuvamile, izindlela ze-non-abakhethayo asetshenziswa ngaphambi amahlumela zokuqala ngemva kokuvuna, noma uma emkhakheni luhlala umusi. Nokho, izenzakalo zamuva enze kube nokwenzeka ukuba usebenzise ezinye izinhlobo yokubulala ukhula kulesi sigaba njengoba isampula ukuze zofuzo
izinhlobonhlobo Ushintshe kanye nzalo izitshalo (isb, soybean, ushukela isithombo sebhitrudi, amazambane, njll), ngoba isakhi zokumelana laba basebenzi. Isenzo of yokubulala ukhula non-abakhethayo kungenziwa ngezindlela ezimbili - ngokuthintana futhi letindzala. Lapho isenzo izidakamizwa contact nomthelela ngqo phezu ngayo. Baqala ukusebenza ngokushesha okukhulu hhayi uqedwe imvula. Ngo isenzo letindzala we ketshezi esebenzayo, lihambe isitshalo ukuze waso ukukhula, okubangela yokuqothulwa yabo. izimali ezinjalo esikuthola kancane simila, kodwa ngempumelelo kakhulu ukubulala ukhula zisetshenziswa nge uhlelo strong futhi wenziwa endaweni ebanzi impande.

Yokubulala ukhula ngoba abakhethayo ukulawula ukhula

ukwakhiwa Herbicidal yesenzo abakhethayo kusebenza izitshalo ezithile ngaphandle kokulimaza kubo, kodwa ukhula ukulawula ukhula isiko yasendle efanayo kuphela. Lezi zimali basonta ezahlukene amakhemikhali amakilasi futhi babe izindlela ezahlukene isinyathelo. Ukuqeda phytotoxicity isiko izidakamizwa ezimweni ezithile zisebenza sinqobe. Yokubulala ukhula ukulawula ukhula ifa selectivity kwamakhemikhali, esekelwe ikhono izitshalo ngokwabo ukubhubhisa compounds zabo enobuthi ku-non-enobuthi. ukubandlulula morphological okusekelwe umehluko ku Sakhiwo sangaphandle izitshalo kutshalwa, okungukuthi ifomu kanye ilungiselelo amaqabunga, kanye izici of ezindaweni zawo (hairiness, emakhilayoni enamathela, nokunye.) - konke lokhu kuvimbela Ukungena of yokubulala ukhula.

Elicacisa ngesimo sendawo selectivity ukhula libhekene nenkanuko edlulele in the ungqimba ongenhla inhlabathi ngokumunca izinhlayiya zayo colloidal (ubumba, humus), lapho umphumela anobuthi zomuthi awufiki izimpande zalesi sihlahla kutshalwa futhi ukhula nikhula ungqimba engenhla inhlabathi ubhujiswe. Indlela ephumelela kakhulu manje yokubulala ukhula abakhethayo ukulawula ukhula. Intengo le mithi incike Ukwakheka yabo futhi mode senzo.
