To develop sightseeing agriculture and ecological environment and evaluate the utilization potential of mountain landscapes of traditional green manures in Guizhou, seven traditional green manures, Vicia villosa var., Astragalus sinicus L., Vicia sativa L., Raphanus sativus L., Lathyrus cicera L., Oil-sunflower, Orychophragmus violaceus (L.) O. E. Schulz, were studied. The temporal and spatial distribution characteristics, visual characteristics of flowers and other landscape benefits, as well as the growth characteristics and nutrient benefits of green manure crops were analyzed. The flowering time of O. violaceus (L.) O. E. Schulz was the earliest, followed by R. sativus L., L. cicera L., A. sinicus L., V. villosa var., V. sativa L. Oil-sunflower was summer green manure. Its initial flowering stage was in mid-June and its florescence was 17-43 days. The length of flowering was O. violaceus (L.) O. E. Schulz > R. sativus L. > Oil Sunflower > V. villosa var. > A. sinicus L. > L. cicera L. > V. sativa L. Oil-sunflower, R. sativus L. was 150-200 cm, 75-95 cm high, respectively. O. violaceus (L.) O.E. Schulz, V. villosa var., V. sativa L. was 25-50 cm high. A. sinicus L., L. cicera L. was 15-25 cm high. V. villosa var. had the most flowers, and Oil-sunflower had the largest flower area. V. villosa var. was the largest in the area of a plant. With regard to the goal of sightseeing and conservation, blue-violet O. violaceus (L.) O.E. Schulz could be planted between February to March, purplish red As. sinicus L., white R. sativus L. could be planted between March and April, and purple V. villosa var. could be planted in April, yellow Oil-sunflower could be planted in June and July, which would enrich the color of Guizhou sightseeing agriculture, prolong the sightseeing time and diversify the tourism brand.
