Embodiment 1

[0029] field experiment

[0030] In Yanqiao Town, three fields where Houttuynia cordata occurred were selected, and five spots were randomly selected for each field, and the damage symptoms and the law of occurrence and development were investigated. From early April to late October every year, surveys are conducted every half a month.

[0031] Research on prevention methods

[0032] stem treatment

[0033] Use 50% carbendazim wettable powder, triadimefon, and thiophanate-methyl to soak the rhizome of Houttuynia cordata respectively. The carbendazim wettable powder is 800 times liquid and is a systemic fungicide , has protective and therapeutic effects, and is effective against Ascomycota and Deuteromycota pathogenic fungi. Its mechanism of action is mainly to interfere with the formation of the spindle in the mitosis of the bacteria, thereby affecting cell division. It can prevent scab, sclerotinia, stem rot, root rot, brown spot, etc., and then divided into three groups, ...

Embodiment 2

[0042] The influence of the number of stem nodes of Houttuynia cordata on the emergence and yield of Houttuynia cordata:

[0043] Materials and Methods

[0044] Test material: YXC-01 (Qionglai population)

[0045] Test method: The test was carried out in the base of Houttuynia cordata, and the pH value of the soil was 6.10. In this experiment, a total of 5 (A), 15 (B), 25 (C), 35 (D), 45 (E), and 55 (F) stem node numbers were set up for seven treatments, repeated three times, and arranged in random blocks. The area of ​​the plot is 9 square meters (6 meters x 1.5 meters), and the amount of seeds used in each plot is 3.4 kg. The seeds were sown on October 16, 2001, and the number of stems used in each plot was recorded when sowing. Apply organic fertilizer at about 2000 kg / mu as base fertilizer, and then apply 0.36 kg of superphosphate, 0.30 kg of potassium sulfate, and 0.20 kg of urea to each plot when sowing. Produced with Daejeon. When harvesting, the yield of plots was...

Embodiment 3

[0071] Effects of suitable sowing date and seed amount on the yield and quality of Houttuynia cordata:

[0072] Test method The test was carried out in Houttuynia cordata base. The experiment adopted a two-factor split-plot design, the area of ​​the plot was 10 square meters (5×2), and the sowing date was the main treatment, with three levels: September 25 (A 1 ), October 15 (A 2 ) and November 4 (A 3 ). Seed amount is used as secondary treatment, and four levels are set: 3kg / plot (B 1 ), 4.5kg / cell (B 2 ), 6.0kg / cell (B 3 ), 7.5kg / cell (B 4 ), repeated three times. Planting and field management are the same as field production. When harvesting, the fresh weight of the above-ground and underground parts was measured in different plots, and variance analysis was carried out. Take the mixed samples of the above-ground part of three repetitions to determine the content of methyl nonanone.

[0073] Determination method of methyl nonanone content Accurately weigh an appro...

Abstract

The invention relates to the technical field of traditional Chinese herbal medicine cultivation, in particular to a herbahouttuyniae cultivation method, which comprises the following steps of: 1) determining a planting time: planting seedlings at a period from the middle ten days and last ten days of September to the first ten days of November every year; 2) determining a planting mode: selecting high-stalk crops for interplanting; 3) preparing the seedlings: conducting asexual reproduction by using subterraneous stems of herbahouttuyniae as reproduction materials; 4) planting the seedlings: directly placing the seedlings on compartment surfaces and covering the compartment surfaces with rice straw or maize stalks after the seedlings are planted; 5) conducting field management: removing weed at the growth period of the herbahouttuyniae, removing ill herbahouttuyniae plants, weak herbahouttuyniae plants and non-herbahouttuyniae crops during weeding, and making sure that the herbahouttuyniae is not damaged; and during top dressing, using farm manure as main fertilizers and chemical fertilizers as auxiliary fertilizers, paying attention to reasonable drainage and irrigation and keeping soil wet at the entire growth period of the herbahouttuyniae; and 6) harvesting at a proper time and the like. By adopting the herbahouttuyniae cultivation method, the yield of the herbahouttuyniae is high, the damage by diseases and insects is reduced, the herbahouttuyniae diseases such as southern blight and zonate spot can be effectively prevented and controlled, and the yield of the herbahouttuyniae and the mass content of medicinal components in the herbahouttuyniae are improved to the utmost extent.

Description

technical field [0001] The invention relates to the technical field of breeding of Chinese herbal medicines, in particular to a breeding method of Houttuynia cordata. Background technique [0002] Houttuynia cordata ( herbahouttuyniae ), also known as zheergen, fencao, 蕺, purple 蕺, wildflower wheat, etc. It is the dry above-water part of the perennial herbaceous plant Bougainvillea of ​​the family Sanbaiaceae. Produced in the provinces south of the Yangtze River Basin in China. In summer, when the stems and leaves are lush, the flower spikes are often harvested, washed, dried in the shade or used fresh. Because the leaves have a fishy smell, it is commonly known as Houttuynia cordata. The average seedling height of Houttuynia cordata is 60cm. Stem cylindrical, 20-45cm long, 0.25-0.45cm in diameter, with obvious nodes; upper part green or purple-red, lower part white, with obvious nodes, fibrous roots grow on lower nodes, glabrous or sparsely hairy. Alternate leaves, he...
