Kukonza kwa Lalin - Kusankha Koyenera kwa Herbicides

1. Zitsamba zilizonse zili ndi mawonekedwe ena owongolera, ndipo ena owongolera udzu akhoza kukhala ochepa kwambiri. Mwachitsanzo, malimitoate ndi othandiza kwambiri pakulamulira wowononga mafuta komanso kugwidwa kwamtchire, koma zotsatira za kuwongolera nkhumba sizodziwikiratu, kapena sizabwino kwambiri.

2. Madera akumaloko ayenera kusankha zitsamba zogwira mtima malinga ndi udzu wamba m'deralo. Cakuoing, Kuomie, Heuoing, etc. amagwira ntchito mogwirizana ndi ma namesfuron-methl ndi chloceuluron nthawi yotsalira ndipo chilengedwe. Ngati udzu wotakata (mbande) zabzalidwa pambuyo polowetsa, zowonongeka zazikulu za mankhwala ophera tizilombo. Pomwe pali namsongole zambiri mu udzu, pogwiritsa ntchito caohejing, herike, hekitala, etc. ali ndi zotsatira zabwino.

3. Sankhani ma herbicide oyenera malinga ndi udzu osiyanasiyana. Malinga ndi miyezo yosiyanasiyana ya kagawika, madera amatha kugawidwa m'magulu a conocotyylenonous ndi madandaulo a docotyylenonous,Malo OyeraNdipo malo ozizira-ozizira, ndi zina mwa mitundu yosiyanasiyana ya maulamuliro amakhala ndi kukana kosiyanasiyana kwa herbicides. Tikudziwa kale kuti dongosolo la kukana mankhwala osokoneza bongo okhwima kuchokera kwakukulu mpaka pang'ono ndi: Zoyia> Beashores> Fodya wa Andergrass> bentrass. Mwachitsanzo, kugwiritsa ntchito udzu - kundende kuwongolera maudzu otambalala mu garineae Maudzu ndi otetezeka kwa udzu; Kugwiritsa ntchito udzu - Kuang Yeang kuti muchitire maudindo obowola oyera ndi otetezeka; Kugwiritsa ntchito udzu - Kuang Yeang kuwongolera maudzu a galamala pamalo ovala maboti otamatira ndi otetezeka kwa udzu; Kugwiritsa ntchito udzu ku Kueds kuti muchepetse namsongole wozungulira mu galamala ku galamala ndi otetezeka, ndipo amathanso kuchotsa namsongole woipa; Mesa-Kuang amatha kuwongolera Cypeus Plandus.

4. Maulamuliro amakhala ndi kukana kosiyanasiyana kwa Herbicides osiyanasiyana.Maulamuliro Ophatikizidwaimatha kugwiritsa ntchito herbicides panthawi yomwe amakula komanso kukula kwake. Maulamuliro achindunji, mukamagwiritsa ntchito herbicides asanabzala, nthawi yotsalirayo iyenera kuganiziridwa, mwanjira ina imakhudzanso mbewu za udzu. Kugwiritsa ntchito ma herbicides otsekeka otsekedwa musanadutse udzu atawcha umboni kumafuna chitetezo cha herbicides. Paziloweredwe mwachindunji pambuyo pa gawo la masamba 5, ma herbicitides ambiri ndi abwino.

5. Kusankhidwa kwa herbicides chifukwa cha magawo osiyanasiyana a namsongole nawonso. A Terdes asanakhale ndi masamba 5, kukana ndi wofooka, mlingo ndi wocheperako ndipo zotsatira zake ndi zabwino. Pambuyo 7 masamba, kuchuluka kwa mankhwalawa, zotsatira zake zimachepa, ndipo chinthu choteteza udzu chimachepa; Mu gawo lachedwa la namsongole, makamaka namsongole atakhazikitsa mbewu, zochititsa zitsamba ndizochepa.

6. Bakuman: Monga chomata cha herbicides, zomwe zimakhudza maluwa ena; Kaya zotsalira za herbicides zidzakhudza mbewu yotsatira ya mbewu; Zofunikira zachilengedwe, zoterezi m'malo omwe anthu, makamaka ana, monga amasewera, masitepe obiriwira, ndi zida zobiriwira, ndipo kuchuluka kwa mankhwala opukutira kuyenera kukhala ochepa momwe angathere.
