Ntsiab cai ntawm kev ua haujlwm
Cov tshuaj ua ntej pib ntawm cov hauv paus hniav thiab cov nplooj ntawm cov nyom, seeps hauv thiab khiav tawm ntawm nws, cuam tshuam cov enzyme acetolactate synthase. Xws li kev cuam tshuam kev cuam tshuam cov kev txuas ntawm cov amino acids. Vim li ntawd, lub hlwb tsis ua haujlwm, qhov nyom nres pheej loj thiab tuag. Cov nyhuv ntawm tshuaj lom yuav pom los ntawm chlorotic stains thiab tuag ntawm kev loj hlob cov ntsiab lus. Cov no yog cov cim qhia meej tias cov nroj tsuag yuav sai sai.
Nws tseem ceeb heev! Qee cov nroj tsuag yeeb yam ua rau cov metsulfuron-methyl. Yuav kom tiv thaiv tau qhov no los ntawm qhov teeb meem, cov kws txawj pom zoo hloov cov herbicides los ntawm ntau pawg tshuaj..
Cov qoob loo cog qoob loo
Thaum rov qab chaw rau cov chaw qaub ncaug, yuav tsum tau txais kev saib xyuas, vim tias tsis yog txhua haiv neeg tuaj yeem tau sown sai li sai tau.

- Caij nplooj ntoos hlav rau lub caij nplooj ntoos hlav yog sprinkled nyob rau theem pib ntawm kev loj hlob ntawm ib xyoo dicotyledonous nyom (2-4 nplooj) thiab perennial dicotyledon nyob rau rosette theem (nyob rau hauv cereals - los ntawm lub sij hawm ntawm 2 nplooj kom txog thaum tillering). Cov dej haus ua hauj lwm: 200-300 l / his los ntawm txoj kev ntawm thaj av thiab 25-50 l / ha - los ntawm aviation;
- lub caij ntuj no cov qoob loo yog sprinkled nyob rau hauv lub caij nplooj ntoos hlav nyob rau hauv thaum ntxov theem ntawm kev loj hlob ntawm txhua xyoo weeds (2-4 nplooj) thiab perennial - nyob rau hauv lub rosette theem (rau cov qoob loo - lub sij hawm tillering). Khoom Noj: 200-300 l / his thiab 25-50 l / h;
- Lub caij nplooj ntoos hlav thiab lub caij nplooj ntoos hlav lub cev tau txau rau thaum pib ntawm cov nroj tsuag (rau cov qoob loo, tillering theem, rau lub caij ntuj no cov qoob loo, thaum caij nplooj ntoo) nrog 2,4-D, 0.35 kg / his. Khoom Noj: 200-300 l / h;
- Flax-dolgun tau txais ib feem ntawm "Singer" nyob rau theem ntawm "Tsob ntoo Christmas", qhov siab ntawm flax - 3-10 cm Txwv: 200-300 l / ha thiab 25-50 l / ha. Hauv qib no, qhov sib txuas ntawm "Singer" thiab MCPA - 150 g / his. Khoom Noj: 200-300 l / his.
Qhov cuab yeej ua tau zoo ntawm nws tus kheej. Tab sis koj tuaj yeem sib tov nrog lwm cov tshuaj, piv txwv, MCPA thiab 2,4-D.

Tuaj ceev
- 4 xuab moos tom qab txau, cov khoom nquag yog ua los ntawm cov nroj.
- Tsis pub dhau 24 teev lawv nres kev loj hlob.
- Tom qab 3-10 hnub, cov cim ntawm kev tuag ua tau tshwm sim.
- On 20-30th hnub lub nroj tsuag perishes tag: nws nyob ntawm nws txoj kev loj hlob, nws rhiab heev thiab huab cua. Cov huab cua tsis zoo yuav ua rau lub txiaj ntsim ntawm kev siv tshuaj yaj yeeb dua.
Lub sij hawm ntawm kev tiv thaiv

Thaum lub hauv av txau thiab cua hlob mus txog 4-5 m / s:
- qee thaj tsam rau muv tsis pub tsawg tshaj 2-3 km;
- Fly bees yuav tsum tau tas rau 8-9 teev.
- qhov chaw rau bees yog tsis pub tsawg tshaj 5-6 mais;
- txo lub sij hawm ntawm sib ntaus ntawm bees mus rau 8-9 teev.
- Mloog cov neeg ntes yuav tsum ceeb toom rau 4-5 hnub ua ntej pib ua haujlwm nrog tshuaj.
