Herbicides ulamuliro udzu: mitundu ndi njira kanthu

Mu chikhalidwe, pali masauzande a mitundu namsongole pachaka ndi osatha. Izi ubiquitous "zosasangalatsa" kupanga mpikisano lolimba kwa zomera mbewu, kuwamana iwo chinyezi, kuwala ndi chakudya nthaka. njira imeneyi monga Kupalira, si nthawi zonse zothandiza kulimbana namsongole, mitundu osatha msanga kumera mu nthaka mbali zotsala za rhizomes lapansi. Izo zinaliri apo, ndi kuthandiza a herbicides kulamulira namsongole.

Zimene herbicides

Herbicides - wapadera mankhwala zinthu anafuna ulamuliro
nambala kapena kupewa kukula kwa namsongole. Komanso, ntchito nyimbo herbicidal n'zotheka kuchepetsa kapena ngakhale kwathunthu kuthetsa kulima ndi Buku kapena makina, potero kuchepetsa imfa chinyezi ndiponso kupewa kukokoloka kwa nthaka. Herbicides anawagawa m'magulu awiri - omwe si kusankha (mosalekeza kanthu) ndi kusankha (kusankha).

Herbicides kulamulira namsongole nonselective

formulations Herbicidal mosalekeza kanthu, pakalibe munda Akutsatira
(Garden) zomera nakulitsa, monga iwo kudya zomera zonse zilipo, ozama mu pamwamba tsamba. Childs, njira sanali kusankha ntchito pamaso mphukira woyamba mukakolola, kapena pamene m'munda zikukhazikitsa nthunzi. Komabe, zochitika zaposachedwapa n'zotheka kuti ntchito mitundu ina ya herbicides mu gulu ili ngati chitsanzo kwa chibadwa
mitundu kusinthidwa ndi hybrids mbewu (mwachitsanzo, soya, shuga Beet, mbatata, etc.), chifukwa chakuti losokonekera kwa kukana kuti nthumwi izi. Zimene herbicides sanali kusankha zikhoza kuchitika m'njira ziwiri - ndi kulankhula zokhudza zonse. Pamene kukhudzana mankhwala kanthu kusonkhezera mwachindunji padziko ankachitira. Iwo anayamba ntchito mofulumira kwambiri osati yagwa ndi mvula. Mu kanthu zokhudza zonse za mankhwala yogwira umaloŵa chomera kuti mfundo yake ya kukula, kuchititsa ikutha awo. ndalama oterowo odzipereka pang'onopang'ono mu mbewu, koma ndi othandiza kwambiri mu kupha udzu osatha ndi chitetezo champhamvu ndi yaikulu muzu.

Herbicides ulamuliro kusankha namsongole

formulations Herbicidal kanthu kusankha ntchito mbewu yeniyeni popanda kuwononga iwo, koma kwa kulamulira namsongole kukula ndi chikhalidwe cha m'munda chimodzimodzi. Ndalama zimenezi a magulu osiyanasiyana mankhwala ndi kukhala njira zosiyanasiyana kanthu. Kuthetseratu phytotoxicity chikhalidwe mankhwala nthawi zina kutsatira ZINGATHANDIZE. Herbicides kulamulira namsongole adzalandira amuzolengedwa selectivity, zochokera luso la zomera okha kuwononga mankhwala awo poizoni mu sanali poizoni. Morphological tsankho zochokera kusiyana dongosolo kunja zomera nakulitsa, ndicho mu mawonekedwe ndi makonzedwe a masamba, komanso peculiarities wa pamwamba (hairiness, phula ❖ kuyanika, ndi zina zotero.) - zonsezi kumathandiza malowedwe a herbicides.

Topographic selectivity herbicide yodziwika ndi fixation mu wosanjikiza chapamwamba nthaka mwa kungolandira particles ake colloidal (dongo, humus), umene zotsatira poizoni mankhwala Kodi sangafikire mizu ya zomera nakulitsa ndi udzu kukula mu wosanjikiza chapamwamba nthaka anawonongedwa. Zothandiza kwambiri tsopano kusankha herbicides kulamulira namsongole. Mtengo wa mankhwala zimadalira zikuchokera awo ndipo akafuna kanthu.
