摘要
为了研究不同生育期喷施“绿速达”缓释液体肥在舒城县舒茶早上的应用效果,对比“绿速达”不同喷施量处理下的表现,对舒茶早农艺性状、产量、营养成分的影响研究。结果显示,适量喷施“绿速达”对加快茶树的生长历期有促进作用;在亩产量方面,喷施1500g/亩“绿速达”相对于施用30kg/亩尿素增产23.5%,喷施1000g/亩“绿速达”相对于施用30kg/亩尿素也增产12.7%,喷施500g/亩“绿速达”相对于施用30kg/亩尿素产量下降5%;在百芽重方面,喷施1500g/亩“绿速达”相对于施用30kg/亩尿素百芽重增加10.5%,喷施500g/亩“绿速达”百芽重相对于施用尿素的试验组下降5%;检测茶汤中最常见的几种营养成分发现只有F1组的茶多酚含量明显高于其他试验组,F1组的游离氨基酸总量明显低于其他试验组。
In order to study the application effect of spraying"Lvsuda"slow-release liquid fertilizer at different growth stages on Shuchazao in Shucheng county,the effects of different spraying amounts of"Lvsuda"on Shuchazao agronomic characters,yield and nutrient composition were compared.The results showed that proper spraying of"Lvsuda"could accelerate the growth period of tea trees.In terms of per mu yield,spraying 1500g/mu"Lvsuda"increased by 23.5%compared with applying 30kg/mu urea,spraying 1000g/mu"Lvsuda"increased by 12.7%compared with applying 30kg/mu urea,spraying 500g/mu"Lvsuda"decreased by 5%compared with applying 30kg/mu urea.In terms of bud weight,the"Lvsuda"of spraying 1500g/mu increased by 10.5%compared with the application of 30kg/mu urea,and the"Lvsuda"of spraying 500g/mu decreased by 5%compared with the application of urea.It was found that only tea polyphenol content in F1 group was significantly higher than that in other test groups,and total free amino acid content in F1 group was significantly lower than that in other test groups.
