Reduction of the energetic consumption and preservation of the s oil structure cultivated with vegetables by using a complex aggregate.

Abstract

Normal 0 false false false MicrosoftInternetExplorer4 Setting up the vegetable crops in spring implies seed bed preparation, fertilization, opening thegutters, working the field and sowing. These actions cause energetic consumption and soil compactionby many passes with machines for every work. These were the reasons for building an experimentalpattern of complex aggregate which executes in a single pass the preparation of the seed bed, openingthe gutters, soil working, starter fertilization and vegetable crops sowing in the spring time, ploughingin the autumn, reducing, in the same time, energetic consumption and preserving the soil structure.Fuel consumption represents 54% of machines total consumption which compete to execute the samework, the aggregates productivity being 113%. The test was made in the experimental field of V.R.D.S.Buzau by autumn ploughing and prepared with the disk harrow in the spring time. No differences havebeen noticed in any of the situations about the work quality, so that the main qualitative work indexesregistered the below values: soil crumbling degree: Gms = 92,4%; Weed perish degree: Gdb = 98%. Thepreparing of the germinative bed section can constitute the basis for making an agricultural machinethat adds to the existent agricultural machines system a machine that completely reduces the horizontalrotor cutters that destroy the soil structure, have high energy consumption and have a negative impacton the environment. The energetic indexes: productivity, fuel consumption, sliding and qualitative workindexes totally favour the complex aggregate, with significant differences.
