Since 1985, the production of spring rapeseed has been developing rapidly in Heilongjiang Province. The annual sown area is more than 1 million mu, and more than 90% of the spring rape mainly concentrates on state farms. At present, the rapeseed has been gradually reformed and perfected according to its reproductive characteristics, local ecology and production conditions from the mechanized cultivation techniques referring to the maturation of wheat and soybean. A complete set of relatively complete Mechanized live broadcast cultivation methods of production. The cultivation techniques are as follows: First, rotation and selection of rape in the main producing areas of crop planting structure accounted for 15 to 25%, should take beans - wheat - rape rotation mode. Selected wheat stubble to ensure that
