摘要： We evaluated the field performance of six new Raphanus sativus L. varieties (Brassicaceae family) for landscape and ecological values with the aim to find new ways of improving the cultivated land quality and develop Chinese countryside. Eleven indices were observed, including total flower number, total flower area, flowering stage, initial flowering stage, and nutrient content of returning field. The weighted correlation degree was calculated using coefficient of variation, and the evaluation was carried out using the grey correlation analysis. There were differences between the ranking of equal weight correlation degree and ranking of weighted correlation degree. The weight in total flower area, flower number, and average flower height was high according to the indices of landscape value; weight of fresh grass yield was medium according to the indices of growth; and the weight of phosphorus and potassium was high according to the indices of ecological value of green manure. Three varieties were ranked in the top three according to equal weight correlation degree and weighted correlation degree. They also yielded the best results based on the grey correlation analysis of coefficient of variation. Thus, these three resources could be given priority for use in green manure technology.
