Experimental Investigation on Energy Saving of Controlled Traffic Conservation Tillage

摘要

Two treatments was conducted in the suburb of South Beijing, to compare the effects of controlled traffic conservation tillage (2CT) and conservation tillage (CT) in terms of the draft force and fuel consumption in planting or subsoiling. The experimental results showed that: there is notable difference in draft force and fuel consumption between controlled traffic and non controlled traffic in conservation tillage. The fuel consumption of the field operation is highly correlated to draft force of the operation, especially in the soil engaging conditions like seeding or subsoiling. While in the two kinds operations as mentioned above, controlled traffic conservation tillage could save force 14%and save fue 27.9%, compared with non controlled traffic conservation tillage.
