Abstract:: A field experiment was conducted to study the effects of green manure on fruit yields and fruit qualities of ‘Ningqi No.5’ wolfberry，which was included added organic manure (T1)，rape straw manuring (T2) and chemical fertilizer only control (CK) treatments，and was used organic manure ‘Shunbao’ and oilseed rape ‘Ganyouza No.1’ as experimental material.The results showed that，compared with CK，the dry fruit yield of T1 treatment was significant increased by 24.1%，100 grain weight of summer and autumn fruit was significant increased by 4.2% and 4.6%，respectively；the dry fruit yield and 100 grain weight of autumn fruit of T2 treatment was significant increased by 19.1% and 11.1%，respectively.Compared with CK，the contents of polysaccharide，protein，flavonoid T1 and T2 treatment in dry autumn fruit of wolfberry were significant increased by 25.1%，26.4%，16.4% and 34.9%，48.5%，24.8%，respectively.The results indicated that under the condition of halving the amount of fertilizer，both added organic manure and rape straw manuring could increasing the yield and qualities of wolfberry dry fruit，which was realized by increase the fruit size，100 grain weight and dry matter accumulation in fruit.Therefore，wolfberry interplanting with rape as green manure not only could decrease the chemical fertilizer application，but also could increase the yield and qualities of wolfberry fruit.
