Abstract:
Taking the Leguminosae，Gramineae，Cruciferae green manure as materials，under the kiwifruit orchard planting，the kiwifruit orchard green manure under the phenophase，weed inhibition rate，soil physical properties，green manure and kiwifruit yield，kiwifruit characters，etc. were reasearched，in order to increase the output of kiwifruit，improve the purpose of the kiwifruit characters and improve soil physical properties.The results showed that,except Trifolium repens L.，the growth time of other green fertilizers was 256-273 days，the whole seedling stage to the first flowering stage was 125-194 days，clover had the longest time，radish had the shortest growth time，other treatment time was about 137-144 days.Soil moisture changed with the change of grass-free treatment over time.Soil temperature at 5，10，15，20 cm and 25 cm depth changed with the change of grass-freetreatment,and the change trend of each layer was similar.Compared with no grass and natural grass，the soil bulk density and specific gravity decreased by 10.32% and 6.07%，the porosity increased by 14.10%.The highest yield per 667 m2 of green manure was 3 825.56 kg，which increased by 267.84% compared with A2，and the highest yield of A4 was 627.76 kg，which increased by 20.61%.Kiwifruit yield was significant positively correlated with single fruit weight (0.972**)，transverse diameter (0.825**) and shape index (0.566**).The weed inhibition first increased,then decreased over time，and the yield of green manure was extremely negatively correlated with soil bulk density (-0.665**) and porosity (-0.472**).Porosity was extremely significant correlated with bulk density (0.704**).To sum up，kiwifruit orchard planting green manure on soil temperature and humidity control effect，can effectively improve the physical properties of soil，can inhibit weeds，increase kiwifruit yield，improve kiwifruit traits.
