The Effects of Organic Fertilizers on Quality of Ligustrum robustum (Kuding Tea)

Effects of five manures(cake fertilizer,livestock manure,straw manure,carbamide and silkworm dropping,3 000 kg/ha for each fertilization)and four different fertilizer levels(0 kg/ha,1 500 kg/ha,3 000 kg/ha and 7 500 kg/ha)were studied on the quality of Ligustrum robustum(Kuding tea).The results indicated that as follows:As to teapolyphenols,the amount of teapolyphenols was significantly higher through fertilization of cake fertilizer more than that of straw manure,silkworm dropping and non-fertilization;The content of total flavonoids through fertilization of straw manure by 1 500 kg/ha and 7 500 kg/ha were significantly more than that of non-fertilization,and that through fertilization of straw manure by 7 500 kg/ha was significantly more than that of 3 000 kg/ha,which was significantly more than that of 1 500 kg/ha,but the difference amongst the five manures and non-fertilization were not significant.The theasaponin amount between the five manures and non-fertilization was not significant,but that by fertilization of straw manure of 3 000 kg/ha was significantly more than that of 1 500 kg/ha.
