摘要
以仙居县主栽品种‘荸荠种’和‘东魁’杨梅衰弱树为材料,以清水为对照,研究在杨梅果实膨大期和转色期喷施稀释800倍的氨基酸水溶肥料对衰弱树复壮树势和改良果实品质的作用。结果表明:喷施氨基酸水溶肥料能显著增加2个杨梅品种的枝梢长度和光合速率,‘荸荠种’和‘东魁’的梢长分别增加32.02%和13.24%,光合速率分别增加54.48%和13.23%;增加了2个品种的单果重、总糖含量和维生素C含量,‘荸荠种’和‘东魁’的单果重分别增加2.62%和15.25%,总糖含量分别增加9.48%和4.30%,维生素C含量分别增加8.30%和7.45%,可滴定酸含量分别降低10.68%和9.52%。综上所述,在杨梅衰弱树果实膨大期和转色期喷施氨基酸水溶肥能在一定程度上复壮树势,显著改善果实品质,值得适度推广。
The main waxberry(Myrica rubra)varieties‘Biqizhong’and‘Dongkui’in Xianju County were used as material to study the effect of spraying 800 times diluted amino acid water-soluble fertilizer(CK:clean water)at fruit expansion and veraison stages on tree vigor rejuvenation and fruit quality improvement of frail waxberry trees.The results showed that spraying amino acid water-soluble fertilizer significantly increased the two waxberry varieties'shoot length by 32.02%and 13.24%,photosynthetic rate by 54.48%and 13.23%,single fruit weight by 2.62%and 15.25%,total sugar content by 9.48%and 4.30%,and vitamin C content by 8.30%and 7.45%,while reduced titratable acid content by 10.68%and 9.52%,respectively.In conclusion,the application of amino acid water-soluble fertilizer at the fruit expansion stage and veraison stage can rejuvenate the waxberry tree vigor to a certain extent and significantly improve the fruit quality,which is worthy of moderate promotion.
