Effect Of Cultivation Technique Optimization On The Growth,Yield And Quality Of Alisma Orientale(sam)juzep

Alisma orientale(Sam.)Juzep is a common medicinal material.With the reduction of the planting area of Alisma orientale(Sam.)Juzep year by year,the share of "Rhizoma Alisma" in the market is increasing.In this study,three factors two times orthogonal rotational combination design was used to explore the effect of cultivation technology optimization on index of each character during transplanting period,drainage period and harvesting period.The regression equation is established with cultivation techniques and indexes.Through the frequency statistic method,combining the grey correlation degree method and the DTOPSIS method,the comprehensive evaluation Alisma orientale(Sam.)Juzep each index,obtains the best cultivation Technical optimization plan,provides the theory basis for the Alisma orientale(Sam.)Juzep of Pengshan standardized cultivation.The main results are as follows: 1.Effects of optimization of cultivation techniques on the growth of Alisma orientale(Sam.)Juzep.The cultivation techniques have different effects on the agronomic traits of Alisma orientale(Sam.)Juzep.The plant height was mainly influenced by the transplanting period.In the early September,it was beneficial to improve the height.Leaf area and leaf number were greatly influenced by transplanting date,followed by drainage period.In early September,transplanting or 43 d to 49 d drying fields were beneficial to increase the leaf area.At the same time,At the same time,more leaves can be obtained from 31 d to 39 d of the drainage field or in late 12 months of the harvest.The roots were mainly affected by transplanting large,and earlier or later transplanting is conducive to the promotion of root growth.Tuber volume is mainly influenced by transplanting period and harvesting period,and transplanting in late mid-9 or harvesting around December 21 is beneficial to enlargement of tuber volume.2.Effects of optimization of cultivation techniques on the accumulation and distribution of dry matter in Alisma orientale(Sam.)Juzep.The effects of cultivation techniques on the accumulation and distribution of dry matter in Alisma orientale(Sam.)Juzep were different.The stem and leaf dry matter accumulation of was mainly influenced by the transplanting period,followed by the drainage period,and transplanting in the early September or draining with 43 d to 49 d was beneficial to the increase of dry weight of rhizome and leaf.In the tuber enlargement stage,effects of transplanting,drainage period and harvest period on the dry weight of root was relatively large,so transplanting in September 20 or draining with 49 d or harvesting around December 21 st was beneficial to increase the dry weight of root.In the period of tuber expansion,the dry weight of the tuber was mainly influenced by the transplanting period and the drainage period,and transplanting in the middle of September or draining with 35 d to 43 d is beneficial to the increase of dry weight of the tuber.The effect of transplanting period on the root and crown ratio of was greater during the whole growth period,and the transplanting in late 9 months or the drainage of 27 d to 35 d in the field is beneficial to the increase of the root and crown ratio.3.Effect of optimization of cultivation techniques on the yield of Alisma orientale(Sam.)Juzep.The optimization of cultivation technology can improve the yield of Alisma orientale(Sam.)Juzep..The yield varies with the change of the level of each factor,the contribution rate of the three factors to the yield was sequentially ranked as: transplanting period > harvest time > drainage period,and regulating the transplanting period is beneficial to the yield.Through the frequency statistics method,the best cultivation technology optimization plan was obtained: the transplanting date from September 11 th to September 16 th,the drainage period is 41 d to 46 d,and the harvest time is from December 11 th to December 16 th.4.Effect of optimization of cultivation techniques on the quality of Alisma orientale(Sam.)Juzep.The effects of cultivation techniques on the quality of rhizome of Alisma orientale(Sam.)Juzep were different.The total ash and acid insoluble ash content were greatly influenced by the transplanting period and the harvest time.The contribution rate of the three factors to both of the two factors is the harvest time > transplanting period > the drainage period,and it is beneficial to reduce the total ash and acid insoluble ash content by transplanting in September 20 th or harvesting in late December or in the drainage field around 46 d.The content of alcohol soluble extract is mainly influenced by the transplanting period.The contribution rate of three factors to the alcohol soluble extract is transplanting period > drainage period > harvest time,and transplanting in early September was beneficial to the accumulation of alcohol soluble extracts.Through the frequency statistics method,the best cultivation technology optimization plan was obtained: the transplanting date from September 6th to 12 th,the drainage period is 34 d to 39 d,and the harvest time is from December 15 th to 19 th.The content of starch was mainly influenced by the period of transplanting and the harvest period.The contribution rate of three factors to starch is the harvest time > transplanting period > drainage period,and harvesting in the mid 12 months is beneficial to the increase of starch content.The content of soluble sugar was mainly influenced by the drainage period.The contribution rate of three factors to soluble sugar content is drainage time > harvest time > transplant period.The drainage time of 21 d is conducive to the accumulation of soluble sugar.The soluble protein was mainly influenced by the harvest time.The contribution rate of the three factors is the harvest time > the drainage period > the transplanting period.The harvest of the first ten days of December was beneficial to the increase of soluble protein content.The content of 23-alisone B was mainly influenced by the harvest time and the transplanting period.The contribution rate of the three factors is the harvest time > the transplanting period > the drainage period.The appropriate delay of harvest is beneficial to obtain higher content of 23-alisone B.Through the frequency statistics method,the best cultivation technology optimization plan was obtained: the transplanting date from September 2nd to7 th,the drainage period is 32 d to 38 d,and the harvest time is from December 10 th to 15 th.The 24-alisone A was mainly influenced by the transplanting period and the harvest time.The contribution rate of the three factors is the transplanting period > harvest time > drainage period.Proper early planting is beneficial to the improvement of its content.Through the frequency statistics method,the best cultivation technology optimization plan was obtained: the transplanting date from September 3rd to 8th,the drainage period is 32 d to 38 d,and the harvest time is from December 12 th to 17 th.The total three terpenes were mainly affected by the drainage period and the harvest time.The contribution rate of the three factors is the drainage period>harvest time>transplanting period.It is beneficial to improve the total three terpenes content by shortening the time of drainage in the field.In summary,the cultivation technology optimization has certain influence on the growth,development,yield and quality of Alisma orientale(Sam.)Juzep.Considering the indexes,combined with frequency statistics,grey correlation analysis and DTOPSIS method,the best cultivation technology for Alisma orientale(Sam.)Juzep was obtained.The best transplanting date was from September 11 th to 17 th,the drainage period was 38 d to 43 d,and the harvest time was from December 15 th to 19 th.
