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.

[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;

Abstract

The invention discloses a cultivation method for medicinal houttuynia cordata and edible houttuynia cordata. The cultivation method for the medicinal houttuynia cordata includes the steps of planting time selecting, seed selecting, planting, field managing and harvesting. The cultivation method for the edible houttuynia cordata includes the steps of planting (after the medicinal houttuynia cordata is harvested, underground parts, stored in the soil, of the medicinal houttuynia cordata serve as breeding material of the edible houttuynia cordata), greenhouse building, film covering, field managing and harvesting. The cultivation method can use the land reasonably, improve the yield of the medicinal houttuynia cordata, reduce plant diseases and insect pests, improve the yield and quality of the houttuynia cordata through reasonable and effective crop rotation and solve the problem that overground parts of the edible houttuynia cordata are in short supply at the end of winter and the beginning of spring (December-February in the next year), so that the overground parts of the houttuynia cordata grow normally in winter and spring, moreover, the quality of medicinal material produced after the houttuynia cordata are planted in a greenhouse is not affected, the land is used reasonably, and economic incomes can be increased.

Description

technical field [0001] The invention relates to a cultivation method of Houttuynia cordata, in particular to a cultivation method of medicinal Houttuynia cordata and edible Houttuynia cordata. Background technique [0002] Houttuynia cordata Thunb. belongs to the genus Houttuynia cordata Thunb., a dicotyledonous plant. It is a herbaceous plant with a foul smell. It has the functions of clearing away heat and detoxifying, eliminating carbuncle and draining pus, and diuresis. Hot wheezing, hot dysentery, hot stranguria, carbuncle and sores, Houttuynia cordata has strong adaptability to the environment, often grows on shady hillsides, village ridges, riverside streams and wetland grasses, and is widely distributed in various provinces and regions in southern China , Northwest, parts of North China and Tibet are also distributed, such as Zhejiang, Anhui, Sichuan, Hunan, Hubei, Guangdong, Guangxi, Guizhou, Jiangxi, Yunnan and other provinces and regions. Sichuan is most suitable ...
