Uticaj širine pneumatika na kvalitet rada sejalice i prinos soje
Impact tire width the quality of work the drill and soybean yield
Univerzitet u Novom Sadu, Poljoprivredni fakultet
Sažetak
Najveći problem široki pneumatici mogu izazvati kada se njihov trag poklapa sa redom sejalice. Tada pojedine sekcije vrše setvu u redovima koji su prethodno sabijeni od strane točkova traktora, najčešće zadnjih pogonskih točkova. Takođe, još veći pritisak na zemljište stvara i širokozahvatna mašina u transportnom položaju. Traktorski agregat sastavljen od traktora Lamorgini i šestoredne sejalice proizvođača Gaspardo (Gaspardo) a modela Magika 6 (Magica 6) izvršilo je setvu. Kvalitet setve utvrđivan je nakon nicanja biljaka. Broj biljaka u redovima 2 i 5 je značajno manji usled kretanja točkova pre prolaska setvenog agregata. Sklop biljaka opada u proseku za oko 7,1 % sa porastom brzine izostavljajući redove 2 i 5. preko kojih je pre setve prolazio točak. Prinos kod adekvatno posejanih redova je 3191 kg ha-1 a u redovima 2 i 5 je 684 kg ha-1. Prosečan prinos na celoj parceli iznosio je 2355,3 kg ha-1. Posledica manjeg sklopa u redovima 2 i 5 jeste smanjeni prinos u proseku za 78,56 % u odnosu na ostale redove. Pri setvi brzinom 6 i 8 km h-1 nije bilo problema u vuči samog setvenog agregata ali je već pri brzini od 10 km h-1 uočen nedostatak snage traktora da pri zadatom stepenu prenosa vrši setvu pomenutim agrgatom.
Abstract
The greatest problem can cause wide tires when their trace coincides with a row planters. Then some section perform planting in rows that were previously compacted by tractor wheels, usually the last drive wheels. Alsostill increasing pressure on land and creates a broad claw machine in transport position. Tractor aggregate consisting of tractor Lamorgini and the six rows producers Gaspardo (Gaspardo) a model Magick 6 (Magic 6) has completed its planting. Quality was determined by seeding after emergence of the plants. The number of plants in rows 2 and 5 is substantially lower due to the movement of the wheel before the sowing aggregate passing. Plant density decreases by an average of about 7.1% with an increase in speed by omitting rows 2 and 5 through which it passed wheel before sowing. The yield of properly sown rows is 3191 kg ha-1 in rows 2 and 5 was 684 kg ha-1. The average yield on the whole plot was 2355,3 kg ha-1. Consequence of the lower assembly in rows 2 and 5 is reduced to an average yield of 78.56 % in comparison to the other rows. During sowing speed at 6 and 8 kg h-1 was no problem traction but is already at a speed of 10 kg h-1 was observed lack of power of the tractor to the requested gear is done seeding the aforementioned agregate.
