Herbicides yopitirira

Herbicides mosalekeza kanthu, kapena, ngati iwo amatchedwa, si kusankha, zimakhudza zomera zonse, komwe kamapezeka pa munda. herbicides amenewa kudutsa mpesa mwa pepala pamwamba wobiriwira. zinthu zimenezi ntchito kukachitika kuti pa munda palibe zomera nakulitsa, ndiye, kapena nthunzi, kapena pamaso kubzala kapena pambuyo yokolola. Komabe, zochitika atsopano analola ntchito herbicide yopitirira komanso herbicides ndi kusankha. Izi zidatheka chifukwa kulima mbewu zosinthidwa chibadwa pa mlingo monga Beet shuga, mbatata, soya. zikhalidwe izi ndi mbewu wapadera kwa kukana kuti ena herbicides amene alibe mavuto zomera.

Pali njira zingapo ntchito zinthu zimenezi, amene mwachindunji amadalira chikhalidwe. Mbewu pachaka akhoza amachititsa presowing munda processing. Izi zachitika pofuna kupewa zikamera wa namsongole ndi kuchepetsa chiwerengero cha mankhwala makina. N'zothekanso kuchita chithandizo mwamsanga pambuyo kufesa pamaso chomera wauka. Pakuti desiccation namsongole ndi chikhalidwe ikuchitika processing chisanadze yokolola. Kupondereza namsongole osatha muyenera kuchita chithandizo positi-kukolola.

Pa mbewu osatha, mwachitsanzo, mu minda ya mphesa, mankhwala ikuchitika pakati pa mitengo kuti yopitirira ya herbicides ali nkhabe cibodzi zomera mbewu. Izi zachitika kupewa zikamera namsongole, amawagwiritsitsa chinyezi komanso kuchepetsa chiwerengero cha cultivations. Chifukwa processing izi kumathandiza kukokoloka kwa nthaka, amene amachititsa mankhwala pafupipafupi.

Herbicides mosalekeza kanthu kugawidwa mwa njira ya ntchito ndi makhalidwe a kanthu pa zomera m'magulu 3: kukhudzana kukhudzana zokhudza zonse kanthu ndi amene zinthu dongosolo muzu ndi mbewu germinating.

Zolankhulirana herbicides monga mankhwala amene bwanji zimayambira ndi masamba a udzu mwachindunji kukhudzana ndi mankhwala. herbicides amenewa yodziwika mu mwamsanga bwanji namsongole ndi kugonjetsedwa ndi mvula. Pa kukhudzana ndi zinthu zofunika njira yachibadwa udzu chosemphana ndi ifa. Komabe, pali drawback - Nthawi zambiri kukula kwa mphukira zatsopano.

Zinthu pang'ono mosiyana zokhudza zonse herbicides ndi namsongole. Chofunika yogwira pang'ono ndi pang'ono anasamuka ku mfundo kukhudzana ndi pamwamba isanafike zomera zikule udzu malo, kuchititsa ikutha mofulumira. Zinthu zimenezi ndi bwino kulimbana ndi udzu osatha, amene mizu yolimba, koma zambiri pang'onopang'ono chosakanikirana ndi adutsa mbewu.

Gulu lachitatu zikuphatikizapo herbicides mosalekeza kanthu, amene cholinga kwathunthu kuwononga germinating mbewu ndi mizu ya zomera. Kawirikawiri herbicides tikuuzidwa mu impso ndi mbewu, panyengo zosiyanasiyana zomera.

Kugwiritsa herbicides zochita mosalekeza ndi "Roundup", "Alazeya", "mphepo yamkuntho", "Glisol". "Roundup" chimagwiritsidwa ntchito m'mayiko onse a dziko. Mogwira amalimbana ndi namsongole onse pachaka ndi osatha, amene wawononga onse mobisa ndi mbali aboveground. Komanso, mankhwala lopanda nthaka ntchito, kutanthauza kuti mbewu iliyonse zingafesedwe kuthira mankhwala. "Roundup" Ndi mmodzi wa herbicides otetezeka. Iye si owopsa kwa chilengedwe ndi anthu pamene ntchito molondola. Mankhwala, omwe umagwiritsidwa pamwamba pa mphukira ndi masamba, odzipereka kwa maola asanu, ndipo umasamutsidwa ku mizu ndi mbali zina namsongole m'ma 7 masiku. Zizindikiro zoyambirira za mmene m'kukoma chikasu ndi wilting zomera. Amenewa ndi noticeable patapita masiku 10, ndi zomera kufa kwathunthu pambuyo masabata atatu mankhwala mankhwala.
