有机肥对粗壮女贞(苦丁茶)品质的影响

摘要

Effects of five manures (cake fertilize r, 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 7500kg/ha was significantly more than that of 3000kg/ha, which was significantly more than that of 1500kg/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.%研究了5个肥种(饼肥、人畜粪尿、秸秆堆肥、尿素和蚕沙,施肥量均为3000 kg/hm,另设不施肥对照处理)和秸秆堆肥4个施肥量(0kg/hm,1500kg/hm,3000kg/hm,7500kg/hm)对粗壮女贞品质(茶多酚、总黄酮和荼皂甙)的影响.结果表明:施饼肥的粗壮女贞茶多酚含量要显著高于施秸秆堆肥、蚕沙与不施肥的;每公顷施秸秆堆肥1500 kg与7500 kg的显著高于不施肥的,每公顷施7 500 kg的也显著高于每公顷施3 000 kg的.关于粗壮女贞总黄酮含量,5个肥种和不施肥处理的差异均不显著,但每公顷施秸秆堆肥3 000 kg的要显著高于每公顷施1500 kg的.粗壮女贞荼皂甙含量,5个肥种和不施肥处理的差异均不显著,但每公顷施秸秆堆肥3000kg的显著高于每公顷施1 500 kg的.
