Study On 2 Species Curcuma Rhizome Plants Character And Application Of Zingiberaceae In Gardens

Zingiberaceae plants are bright and colorful,with high value and good health care.It can be used to cut flowers,potted plants and water and play an important role in landscape application.Main purpose of this paper is to study zingiberaceae plants of the genus curcuma nanling rhizoma zedoariae and torch turmeric way of cultivation,growth characteristics and flowering characteristics,and explores their root physiological and biochemical changes during storage and training,for the production and application of curcuma flowers provide direct technical guidance;Explore the ornamental effect of ginger plant in landscape and new application.Four kinds of condition of nanling zedoary turmeric(Curcuma kwangsiensis var.Nanlingensis N.L iu et X.Y.M a)the roots(class a: roots with turmeric,retain the old root and rhizome don’t separate;B: roots without turmeric,retain the old root,rhizome don’t separate;C: roots without turmeric,cut off the old root,rhizome don’t separate;class D: roots without turmeric,cut off the old root,each root separate)buy in sand or peat soil cultivation;The torch turmeric is stored in the high temperature sand before and after storage.The growth and development indicators and physiological and biochemical indexes of all experimental materials were observed.The main results are as follows:1.The nanling rhizoma zedoariae and torch turmeric rhizome flowering characteristics of observation and measurement: from the perspective of the result of measurement,nanling rhizoma zedoariae cuttlefish length is about 35 cm,inflorescence length is about 15 cm,about 8.1 cm in diameter.The upper bracts are bright purple and the base is white.The rate of flowering of the roots of the rhizoma rhizoma,which was processed,showed a decrease in the rate of flowering,and the rate of flowering of the A1 treatment group was 44.4 % significantly greater than the other treatment group.The D2 treatment group had the lowest flowering rate,at16.7%,the worst effect.Potted torch turmeric flowering rate is relatively low,thecultivation of 15 d after flowering rate was only 11.1%,in the cultivation of day 90 flowers fade,the sand temperature sprouting hydroponic than directly in the peat soil cultivation of flowering rate higher than 8.3%.2.The nanling rhizoma zedoariae and torch turmeric root physiological indexes determination results showed that both the roots before and after the storage water content,protein content,reducing sugar content and soluble sugar content difference is not big,but the content of malondialdehyde significant difference,the torch turmeric rhizome malondialdehyde content is 0.69 mu mol/L,significantly higher than that of nanling rhizoma zedoariae,nanling shows only 0.13 mu mol/L;The amount of soluble sugar content of the rhizoma was 0.58%,and the torch was 0.56%.After storage,the rhizoma was 0.64%;The flare was 0.53%;The protein content was0.47 percent and the torch was 0.52 percent.After storage,the protein content of the rhizoma was 0.46%,and the torch was 0.43%.The contents of the rhizoma zedozae were 72%,and the torch was 65%,and the contents of the rhizoma was 77%,and the torch was 67%.Overall,the two kinds of turmeric plant protein content,reducing sugar content,soluble sugar content is slightly higher after storage,storage after the bulb is better.Nanling zedoary turmeric root physiological characteristics of four kinds of condition,both in sand culture and soil culture,its protein content and reducing sugar content and soluble sugar content difference is not big,but the content of malondialdehyde significant difference,A kind of malondialdehyde content was significantly lower than other treatment;The root method of the root method is significantly higher than the other treatment,indicating that the treatment of the root is not cut in the way that helps to reduce the amount of propyl dialdehyde.The root treatment method was a significantly lower level of saratin than soil.The highest amount of soluble sugar in A type A state of A under the condition of the sand matrix culture,with 7.15%,The overall protein content is increasing.The root protein content of A class was16.77%;The B class was 16.89%,the C was 15.43%,and the D class was 15.43%,which was not the same as the increase in the soluble protein.The results show that the rhizoma rhizome is not syncopated by the root of the rhizome and the method ofstorage is better(A1).3.The ginger flower garden application results show that: guangzhou green space in the common ginger zingiberaceae plants application types with hua xie yan mountain(Alpinia zerumber cv.Variegata),yan shan jiang(Alpinia zerumbet)and grass nutmeg(Alpinia katsumadai Hayat),occasional species for educational(Alpinia oxyphylla)and white jiang hua(Hedychium coronarium),nanling zedoary turmeric(Curcuma kwangsiensis),widely used zingiberaceae plants flourish in the park,not only can improve the environment for people’s physical and mental health also play a critical role,but now zingiberaceae plants in residential area has a small application,application rarely road green belts.The application of park and residential area is more diverse,the ornamental effect of flower period is very good.
