2 、 Kev ntsuas kev ntsuas

(1) Kev sib xyaw ua ke ntawm soybean thiab pob kws

Nyob rau sab hnub poob ntawm Tuam Tshoj, muaj dej nag ntau, ntau hom nroj tsuag, thiab nws nyuaj rau tswj lawv.Pob kws yog sown ua ntej soybeans, thiab kev siv tshuaj tua kab mob yuav tsum "sau thiab ua ke".Tom qab sowing thiab ua ntej yub, cov av yuav tsum tau muab khi nrog metolachlor (los yog acetochlor) + thiofensulfuron methyl thiab lwm yam tshuaj.Yog hais tias muaj nroj tsuag nyob rau hauv lub teb ua ntej sowing, lub teb yuav tsum tau sprayed nrog glyphosate tsuag;Yog tias cov av sealing tsis zoo thiab cov qia thiab nplooj yuav tsum tau kho, nicosulfuron methyl + chlorofluoropyranoxyacetic acid (los yog dichloropyridic acid, methimaxone) tuaj yeem siv los tswj cov qia thiab nplooj (hauv thaj chaw cog pob kws) ntawm qhov thib peb. mus rau thib tsib nplooj theem ntawm pob kws seedlings.

Peb hnub ua ntej soyed ntawm soybean, directional tshuaj tsuag ntawm glyphosate yog nqa tawm nyob rau hauv lub teb.Tom qab sowing, ua ntej cog, cov tshuaj tua kab xws li promethazine (los yog acetochlor) + thiophensulfuron raug xaiv rau kev kho av sealing.Yog hais tias cov av sealing nyhuv tsis zoo tagnrho thiab yuav tsum tau kho los ntawm qia thiab nplooj, quinclovir.

Nyob rau hauv Dej Hiav Txwv, Huaihai River, nruab nrab thiab qis qis ntawm tus Dej Yangtze, thiab cov cheeb tsam qaum teb sab hnub poob, taum pauv thiab pob kws tau sown ib txhij.Kev siv ntawmtshuaj tua kab mob Feem ntau yog raws li kev kho av sealing ua ntej seedlings tom qab sowing, uas yuav tsum tau ua kom tiav nyob rau hauv 2 hnub tom qab sowing.Cov av raug kaw nrog cov tshuaj xws li promethamide (los yog metolachlor, acetochlor) + azosulfochlor (los yog thiophenuron).Thaum cov av hauv thaj teb uas cov qoob loo yav dhau los yog hom qoob loo raug kaw nrog tshuaj tua kab, nws yog qhov zoo tshaj plaws los ua rotary tillage kom tshem tawm cov stubble, tsim cov dej noo, thiab tom qab ntawd sow thiab siv tshuaj tua kab ua ntej cog;Rau kev cog qoob loo ncaj qha nrog cov nplej stubble, nws yog ib qho tsim nyog yuav tsum tau ua kom cov dej ntau ntxiv rau ib mu, thiab yog tias muaj kev tso cai, kev ywg dej raws sij hawm yuav tsum tau nqa tawm tom qab daim ntawv thov.tshuaj tua kab;Hauv thaj chaw arid thiab cua xws li qaum teb sab hnub poob, nws yog qhov zoo tshaj plaws los sib tov av tom qab thovtshuaj tua kab mob, thiab raws sij hawm cov dej hauv cheeb tsam uas tej yam kev mob tso cai.

Thaum cov nyhuv sealing ntawm cov av tsis zoo thiab cov qia nplooj ntoo yuav tsum tau kho, nws tuaj yeem siv rau hauv 3 ~ 5 nplooj theem tom qab cog pob kws, 2 ~ 3 nplooj theem ntawm taum, 2 ~ 5 nplooj theem ntawm cov nroj tsuag. .Raws li cov nyom nyom hauv zos, nicosulfuron (los yog oxazolone) + bentazone (los yog cloflupyroxyacetic acid) Nyob rau hauv cov noob taum, quinoxal (los yog high efficiency flumetafop-p-ethyl) + dimethasone (los yog ethyl flumetafop-ethyl) yog siv rau qia thiab nplooj. directional spray weeding (lub cev curtains yog siv los cais pob kws thiab taum mog).Nyob rau theem tom ntej, cov nroj tsuag uas nyuaj rau tswj tau tuaj yeem raug tshem tawm manually.
