Mabala ozungulira ozungulira komanso okhalitsa

Kufotokozera Kwachidule:

1, Kuphwanya nthaka moyenera:

Ndi kapangidwe ka tsamba lopindika kapena lolunjika, tsambalo limadula nthaka mwachangu likazungulira, ndikupanga gawo laling'ono komanso lotayirira, zomwe zimapangitsa kuti kubzala ndi kuthirira kukhale bwino.

2, Zosagwira ntchito komanso zolimba:

Zipangizo zake zimakhala ndi chitsulo cha masika cha 65Mn kapena chitsulo cha alloy cha carbon. Pambuyo pozimitsa ndi kutenthetsa, zimakhala zolimba kwambiri, zolimba bwino, zosagwirizana ndi kuwonongeka komanso zimakhala ndi moyo wautali.

Chogwirira ntchito chozungulira ndiye gawo lalikulu la ulimi (monga chogwirira ntchito chozungulira, chogwirira ntchito zazing'ono, chobwezera udzu, ndi zina zotero), chomwe chimagwiritsidwa ntchito makamaka polima nthaka, kuphwanya nthaka, kupalira udzu ndi kuyika udzu m'manda. Kapangidwe kake kapadera ka tsamba ndi zinthu zake zimatsimikizira kuti ulimi umagwira ntchito bwino komanso molimba, koyenera mitundu yosiyanasiyana ya ulimi monga nthaka youma, minda ya mpunga, minda ya zipatso, ndi zina zotero.

1. Tsamba lopindika lopangidwa mwasayansi: Tsambali lili ndi mzere wopindika wokonzedwa bwino ndi hydrodynamics, zomwe zimapangitsa kuti likhale lolimba pang'ono likalowa m'nthaka komanso lizigwa bwino, zomwe zimathandiza kuti lidule ndikutaya nthaka mosavuta.

2、Kuswa nthaka bwino kwambiri: Pambuyo pa njirayi, zibulunga za nthaka zimasweka bwino komanso mofanana, ndipo nthaka imakhala yomasuka. Imatha kudula bwino zotsalira za mbewu ndikuzisakanizira mu nthaka kuti ipange malo abwino obzala mbewu, ndikuyika maziko olimba obzala.
