水晶泥培养对‘玛瑙桂莪术’水培开花特性的影响

Effect of Crystal Mud Cultivation on Flowering Quality of Curcuma kwangsiensis‘Manao'During Hydroponics

以姜黄属广西莪术新品种‘玛瑙桂莪术’为试材,采用水培方法,研究了水晶泥对水培至不同发育阶段的‘玛瑙桂莪术’开花表现的影响。结果表明:催芽结束后立即使用水晶泥培养比一直水培的对照组开花率高;清水培养6d后使用水晶泥培养的根茎发育至初开所需天数最短,苞片色泽1级根茎个数最多,花序直径、花梗长度与粗度与对照相比均有显著差异;清水培养12d后使用水晶泥培养的根茎花枝寿命最长,盛花期最长;结果表明清水培养6d后使用水晶泥培养、每5d浇1次水的处理组能显著提高‘玛瑙桂莪术’的商品品质。

Tking Curcuma kwangsiensis ‘Manao＇as material,the effect of crystal mud cultivat：on on flowering quality of Curcuma kwangsiensis ‘Manao＇which was hydroponic in a range of days via hydroculture were studied. The results showed that an increase in bloomed ratio was observed in crystal mud cultivation and watered every 5 days after forced sprouting. Significant difference was found in inflorescence diameter, peduncle length and diameter between treatment with crystal mud cultivation after finishing hydroponic for 6 days （CM-6） and CK （one without crystal mud）. An increase in inflorescence diameter, peduncle length and diameter was noted in CM-6, ：whereas inflorescence diameter, peduncle length decreased significantly in CK. Furthermore,CM-6 had more bulbs in 1st ciass of bracteole color and took the shortest days to open the first flower. Treatment with crystal mud cultivation after finishing hydroponic for 12 days significantly increased ‘Manao＇flower longevity and period of more than half flower bloomed. The experiment showed that treatment with crystal mud cultivation and watered every 5 days after finishing hydroponic for 6 days significantly increased ‘Manao＇ flower quality.
