Oilseed rape (Brassica napus L.) is an important oil crop which has the largest planting area in China. In recent years however, several factors, such as labour shortage, low planting benefit and motivation of farmers, lead to expansion of winter fallow field year by year. This present paper studied its greater advantages of rapeseed on land use and conservation, mainly including its ability of optimizing soil structure, increasing soil nutrients (as green manure), and improving soil fertility. Meanwhile, due to its superior adaptability to environment, oilseed rape could apply as pioneer crop to amending the obstacle soil, and thus the natural resources (light, heat, water, and soil) in winter could be efficiently utilized. Winter oilseed rape does not compete with grain for land use and has the greatest potential to exploit winter fallow field for both benefiting the subsequent crops and taking full of its advantage in land conservation. It is of great significance to promote high yield of grain and oil, in order to ensure both security of edible oil supply and sustainable agricultural development in China.

Key words: oilseed rape, land use and land conservation, winter fallow field, rice-rapeseed rotation, green manure crop, pioneer crop
