2. Kev ntsuas

(1) Soybean thiab pob kws ribbon intercropping

Nyob rau sab qab teb sab hnub poob, dej nag muaj ntau, thiab muaj ntau hom nroj tsuag, uas nyuaj rau tswj.Pob kws cog ua ntej soybeans thiab siv tshuaj tua kab mob yuav tsum tau "tua ua ke".Tom qab cov pob kws tau sown, siv metolachlor (los yog acetochlor) + thifensulfuron-methyl los kaw cov av.Yog tias muaj cov nroj tsuag hauv thaj teb ua ntej cov pob kws sown, koj tuaj yeem siv cov tshuaj glufosinate-ammonium;Kev sib khi ntawm cov av tsis zoo yog qhov yuav tsum tau kho cov qia thiab nplooj, nicosulfuron + fluroxypyr (los yog clopyralid, bentazone) tuaj yeem siv rau kev taw qhia (pob kws cog qoob loo) qia thiab nplooj txau ntawm 3rd mus rau 5 nplooj nplooj tom qab cog pob kws.

Peb hnub ua ntej soybean soying, glufosinate raug xaiv rau kev coj los txau rau hauv kab khoob hauv thaj teb.Tom qab sowing thiab ua ntej cov yub, cov av raug kaw nrog tshuaj tua kab xws li metolachlor (los yog acetochlor) + thifensulfuron-methyl.Yog hais tias cov av sealing nyhuv tsis zoo tagnrho thiab yuav tsum tau txau ntawm stems thiab nplooj, quizalofop-pp (los yog high-efficiency fluroxyfop-pp, fluazifop-pp, clethodim) + B Carboxyfluorfen (los yog bentazone) tsom (tseem taum cog thaj tsam) qia thiab nplooj tsuag.

Hauv Huanghuaihai, nruab nrab thiab qis qis ntawm Yangtze River, thiab Northwest Tuam Tshoj, taum pauv thiab pob kws tau sown tib lub sijhawm, thiab cov tshuaj tua kab mob feem ntau yog siv tom qab sowing thiab pre-emergence av sealing kev kho mob, uas yuav tsum tau ua kom tiav nyob rau hauv 2. hnub tom qab sowing.Kev sib khi av yog ua los ntawm kev siv cov tshuaj ua kom zoo nkauj metolachlor (los yog metolachlor, acetochlor) + fensulfame (los yog thifensulfuron-methyl) thiab lwm yam tshuaj.Thaum cov av raug kaw nrog cov tshuaj tua kab mob hauv thaj teb uas yav dhau los stubble yog nplej, nws yog qhov zoo tshaj plaws los ua rotary tillage kom tshem tawm stubble, tsim cov dej noo, thiab tom qab ntawd sow thiab siv tshuaj tua kab ua ntej cog;rau cov teb uas cov nplej stubble tau tshaj tawm ncaj qha, nws yog ib qho tsim nyog yuav tsum tau ua kom cov dej haus ib mu, thiab siv tshuaj tua kab yog tias ua tau.Tom qab ntawd, dej hauv lub sijhawm;Nyob rau hauv cov cheeb tsam nrog drought thiab sandstorms xws li Northwest, nws yog qhov zoo tshaj plaws los sib tov cov av tom qab siv tshuaj tua kab mob, thiab dej nyob rau hauv lub sij hawm uas tej yam kev mob tso cai.

Thaum cov nyhuv sealing ntawm cov av tsis zoo thiab qia thiab nplooj tshuaj tsuag yuav tsum tau siv, nws tuaj yeem siv rau ntawm 3-5 nplooj theem tom qab cog pob kws, 2-3 taum pauv ntawm peb-nplooj theem, thiab cov nroj tsuag ntawm 2-5. nplooj theem.Raws li cov nyom nyom hauv zos, pob kws tuaj yeem xaiv tau.Nicosulfuron (los yog oxaflumezone) + bentazone (los yog fluroxypyr), thiab cov teb taum mog xaiv quizalofop-p-ethyl (los yog high-efficiency fluroxyfop) + bentazone (los yog fluroxyfen-ethanol) ) Stem-nplooj directional spraying rau cov nroj tsuag (siv cov ntaub thaiv rau lub cev. pob kws thiab soybeans rau txau).Nyob rau theem tom ntej, kev tswj cov nyom nyuaj tuaj yeem raug tshem tawm manually.
