Embodiment 1
[0036] Effect of suitable sowing date on yield and quality of Houttuynia cordata:
[0037] experiment method
[0038] The experiment was carried out in Houttuynia cordata base, and the experiment adopted single factor random area grouping. The area of the plot was 13 square meters (3.3×4). ), B4 (June 1st), B5 (June 25th) at 5 levels, and each level was repeated three times. Analysis of variance, simultaneous determination of the volatile oil content of each level, the content of 4 components (4-terpineol, α-terpineol, bornynol acetate, methyl nonanone).
[0039] Determination of 4 kinds of component content Weigh an appropriate amount of n-undecene, 4-terpene alcohol, α-terpineol, bornyl acetate and methyl n-nonanone, add n-hexane to make 1ml containing 2mg, 1mg, 4mg, 6mg, 2mg of the stock solution, namely the reference substance solution, take 50g of fresh Houttuynia cordata, chopped, accurately weighed, put in a round bottom flask, add 150ml of water, connect the volat...
Embodiment 2
[0053] The effect of the amount of seeds used on the yield and quality of Houttuynia cordata:
[0054] experiment method
[0055] The experiment was carried out in Houttuynia cordata base, and the experiment adopted single-factor random area grouping. The area of the plot was 13 square meters (3.3M×4M), and YZ1 (611.5kg / mu), YZ2 (487kg / mu), YZ3 (359kg / mu) were set. 3 levels, each level was repeated three times, planting and field management were the same as field production, and the dry weight of the aboveground part of Houttuynia cordata was measured in plots at harvest time, and variance analysis was performed.
[0056] Table 5 The effect of the amount of seeds used on the yield of Houttuynia cordata
[0057]
[0058] Table 6 method analysis results
[0059]
[0060] Table 5 and Table 6 show that there is a certain difference in the effect of different seed amounts on the yield of Houttuynia cordata aboveground (P <0.05), and the growth of Houttuynia cordata in YZ...
Embodiment 3
[0062] Effects of different grades of stems on the yield of Houttuynia cordata:
[0063] experimental method
[0064] The experiment was carried out in Houttuynia cordata base, and the experiment adopted single factor random area grouping. ), ZJ4 (outside grade) 4 levels, each level repeated three times. Planting and field management are the same as field production. When harvesting, the dry weight of the aboveground part of Houttuynia cordata was measured in different plots, and the analysis of variance was carried out. At the same time, the volatile oil content of each level and the content of 4 components (4-terpineol, α-terpineol, bornynol acetate, and methyl nonanone) were determined.
[0065] Classification of seed stems Class I: internode diameter greater than 4.3 mm, internode length greater than 4.1 cm, stem length greater than 16.8 cm;
[0066] Grade II: internode diameter 3.4-4.3 mm, internode length 3.2-4.1 cm, stem length 13.6-16.8 cm;
[0067] Grade III: in...
