Experiments on Rice Bowl Dish Precision Seeder Long and Short Paddy Grain in Seeding Processing
摘要
Abstract
In order to optimize the parameters of the rice Bowl-dish precise seeder to improve the plant performance , the three factors five levels quadratic orthogonal rotational regression experiment has been conducted by using rice bowl -dish precise seeder , studying the effect on seeding rate and the damage rate by the shaped hole diameter , shaped hole thick-ness , seed box speed .Empty test is commonly used in Heilongjiang province rice varieties kongyu 131 ( long grain ) and kenjian3(short grain),The results shows that the order of factors affecting rice seeding rate is the type of hole diameter , shaped hole thickness , seed box speed ( short grain ) , shaped hole thickness , seed box speed , the type of hole diameter ( long grain); the order of factors affecting rice injury rate is the type of hole diameter , shaped hole thickness , seed box speed ( short grain ) , the type of hole diameter , seed box speed , shaped hole thickness ( long grain ) .The result including more optimal parameters(the type of hole diameter is 10mm, shaped hole thickness 4mm; seed box speed 0.290m/s (short grain) and the type of hole diameter is 11mm, shaped hole thickness 4mm; seed box speed 0.240m/s(long grain ) respectively ) and performance indicators ( the seeding rate is 94 .81%;damage rate 0 .479%( short grain ) and the seeding rate is 95.37%;damage rate 0.368%(long grain) )provide the basis for design and performance improvement of bowl-dish precision seeder .关键词
