Cov haujlwm tseem ceeb
Av Crushing thiab Leveling: Siv concave discs yob thiab txiav rau hauv av, rhuav tshem clods thiab ridges tom qab plowing, thiab ua rau saum npoo thiab xoob.
Weed Control and Stubble Management: Txiav cov nyom nyom los yog cov qoob loo seem, nplawm thiab tig cov av, thiab tshem tawm cov nroj tsuag thiab cov seem ntawm cov qoob loo yav dhau los.
Kev Sib xyaw thiab Npog: Sib tov cov chiv, quav cab, lossis cov qoob loo uas seem rau hauv av, npog saum npoo kom txo cov dej noo, thiab txhim kho av aeration thiab dej tuav.
Siv Tau Ua Haujlwm Scenarios
Post-Plowing Land Preparation: Feem ntau yog siv rau crushing av tom qab plowing los npaj seedbeds rau sowing.
Pre- Kev Npaj Sowing: Looseing av thiab tshem tawm cov nroj tsuag ua ntej sowing, rhuav tshem qhov chaw compaction, thiab xyuas kom meej ib puag ncig haum rau noob germination.
Post-Kev Kho Mob Sau: Siv rau kev tillage ntiav thiab tswj stubble tom qab sau, ua tiav straw chopping rov qab mus rau lub teb thiab reclamation ntawm pov tseg.
Av Adaptation thiab Hom
Adaptation to Heavy Clay Soils: Heavy disc harrows muaj peev xwm nkag mus rau hauv av, tshwj xeeb tshaj yog haum rau cov av nplaum hnyav, cov av pov tseg, thiab cov nroj tsuag - kab mob.
Qhov sib txawv ntawm hom: Notched disc harrows muaj zog crushing peev xwm, haum rau siab -stubble teb; Lub teeb harrows yog tsim rau kev npaj av zoo ntawm cov av cultivated thiab lub teeb rau nruab nrab av.
