Mapira seeder kale Sumerians

Kufesa mbewu (mawotchi), imatengedwa ndi asayansi, anaonekera Baibulo wosazindikira wa theka zaka zikwi BC mu Sumeria wakale, koma sanali ambiri, kotero kumizidwa mu chisokonezeko. Re-chitukuko cha zida za ulimi zimapezeka East, ku China, kumene m'zaka chachiwiri BC, anatulukira yachitsulo planter ndi angapo a deferens vas. Ku Ulaya, gulu adakhala ambiri za m'ma chakhumi ndi chisanu ndi chinayi. Mpaka nthawi imeneyo, munda wa tirigu anaponyedwa ndi dzanja, ndiyeno anawonjezera dropwise harrow, amene kwambiri bwanji yokolola.

Modern tirigu seeder - ndi zida zimene amapereka wina anaika mu nthaka mbewu zinthu mulingo woyenera chitukuko chifukwa chakuti zomera mtsogolo zambiri ili pa mtunda wina, kotero saletsa ndi mzake kukula.

Mapira seeder mukugwirizana imodzi kapena zina siyana zotsatirazi:

- zida wamba umaonetsera ankafika mwanjira wamba anatseka akufa pochita (mtunda kakang'ono pakati pa mizere ya ku seveni mpaka eyiti masentimita) mu lonse, lamba kapena mtanda njira;

- checkrow kufesa, pambuyo ntchito zimene zimagwidwa anabzala mu ngodya ya rectangles kapena mabwalo;

- kukaikira mazira zida (mbewu zobzalidwa chisa, zidutswa zina zingapo mu umodzi);

- wa akufa pochita lili (mbewu anayikidwa mu nthaka pa mtunda wofanana Chrixitu);

- kawirikawiri ntchito mayunitsi razbrosnye kuti Kungoti anaika pa mbewu nthaka padziko (zambiri ntchito kufesa mbewu dziko herbaceous).

Mapira seeder ndi ziwiya zambambande kuti akhoza kukwaniritsa ntchito angapo nthawi imodzi. Zopangapanga ndondomeko ndi feteleza pa kubowola akhoza anafotokoza motere: mbewu za bokosi tirigu kulowa vas deferens, kumene iwo akuwonjezeka fetereza, ndiye ntchito onsewo mbale, zigawo onse anayikidwa mu nthaka ndi kuwaza pamwamba pa nthaka. Komanso, kufesa zida aligns nthaka pambuyo ntchito zimenezi, amene kumawonjezera mayiko processing wake zina.

Mapira seeder angatanthauze mtundu kapena chilengedwe. Tikaphatikiza zitsanzo kulola mbewu chikhalidwe (bwinobwino mbewu ndi zernotravjanogo), pamene ena ankafika amafuna zipangizo zina zapadera, amene kwambiri apadera (chimanga, shuga Beet, nyumba etc.). makina wina chilengedwe zambiri m'malo angapo wamba.

Mapira seeder (wokwera) ntchito kamodzikamodzi kuposa njira ngolo kuti amalola pokonza malo aakulu ndi kupanga lumikiza mayunitsi angapo. Mwachitsanzo, mbewu akhoza kutengapo mbali kuyambira 1 mpaka 6 trailed akufa pochita mbewu amatengedwa kukhala zovuta umodzi, umene uli thalakitala wina. Wokwera zitsanzo omwewo zambiri ntchito chifukwa chodzala mbewu m'minda kakang'ono komwe muyenera kusinthasintha apamwamba ndi kulemekeza nthaka (Mabaibulo wokwera pafupifupi nthawi zonse mosavuta ngolo).
