[0034] like Figure 1-5 As shown, a method for planting Houttuynia cordata is provided in an embodiment of the present invention.

[0035] like Figure 1 As shown, the planting method of the present invention adopts the form of soilless cultivation, which ensures that the seedlings used for potted production are of uniform size, free from pests and diseases, and have a well-developed root system.

[0036] like Figure 4 As shown, the planting method uses a first container and a second container to plant Houttuynia cordata; wherein, the second container is filled with a medium for planting Houttuynia cordata; the second container is located in the accommodating cavity of the first container, and the side wall of the second container and the side wall of the first container form an annular space for the growth of Houttuynia cordata, and the side wall of the second container is provided with a plurality of through holes connected to the annular space.

[0037] The method adopts a potted planting method of a first container inside a second container, which is innovative in planting. When the Houttuynia cordata grows to the harvest period, the Houttuynia cordata rhizome is mainly located in the annular space, and the Houttuynia cordata leaves are located in the second container, thereby separating the above-ground branches and leaves from the underground stems, making it easy to harvest, and the root system is white and clean. Compared with field planting, the growth cycle can be shortened by 15-20 days, the yield is increased by 10%-20%, and the planting is not restricted by region and season. In addition, the unique planting method of potted plants can be placed indoors, and the green leaves and inflorescences are beautiful and highly ornamental.

[0038] It should be noted that the medium in the present invention can be water, peat or forest leaf mold, vermiculite, etc., to facilitate the contact of Houttuynia cordata with the nutrient solution, and the present disclosure is not limited to this.

[0039] Considering that the diameter of the rhizome of Houttuynia cordata will not exceed 6mm. Therefore, continue to refer to Figure 4 , the width of the through hole in the horizontal direction does not exceed 6 mm, and the length of the through hole in the vertical direction is not less than 30 mm. Through such an arrangement, on the one hand, it is ensured that the rhizome of the Houttuynia cordata can extend out of the through hole during its growth, and on the other hand, the length of the through hole in the vertical direction is not less than 30 mm, which ensures that the cross-sectional area of ​​the through hole is large enough to facilitate the extension of the rhizome of the Houttuynia cordata.

[0040] The planting methods of Houttuynia cordata include:

[0041] Step 1: Use the short-stem sowing method to sow the Houttuynia cordata in the second container, and use commercial coconut bran as the medium. The seed stems should be fresh, thick, free of pests and diseases, and mature old stems;

[0042] Step 2: Water the second container regularly until new shoots appear, which is environmentally friendly and convenient;

[0043] Step 3: When new sprouts appear, pour out the water in the second container and add nutrient solution, wherein the EC value of the nutrient solution is in the range of 1.5-2.0; the pH value of the nutrient solution is in the range of 5.5-6.5; wherein, after adding the nutrient solution, it is necessary to pay attention to the stock, pH value and EC value of the nutrient solution in real time. When the stock of the nutrient solution decreases, it is necessary to add nutrient solution. When the pH value and EC value of the nutrient solution are lower or higher than the reference value, it is necessary to replace the nutrient solution in the second container;

[0044] Step 4: Place the first and second containers in a cool place indoors until new leaves appear on the Houttuynia cordata. The shape of the new leaves can refer to Figure 1 ;

[0045] Step 5: After the new leaves appear, expose the Houttuynia cordata to the sun for supplementary light. After the new leaves appear, increasing the supplementary light time can appropriately speed up the growth. Its growth status can be referred to Figure 2 ;

[0046] Step 6: When the Houttuynia cordata grows out of the through hole of the second container and grows to maturity in the annular space between the first container and the second container, Figure 3 and Figure 4 In the state of being in the middle, the Houttuynia cordata in the annular space is harvested.

[0047] In the above planting method, the above-ground leaves and underground stems of the Houttuynia cordata are separated, which is convenient for harvesting. Each node is strictly controlled during the cultivation process, which ensures food safety while shortening the growth cycle of the Houttuynia cordata. In addition, the product has certain ornamental value.

[0048] As an optional implementation manner, the specific steps of step one include:

[0049] Cut the selected seed stems from the internodes, each section is 4-6cm, and 2-3 nodes are retained in each section. Before sowing, put them into 800 times 50% carbendazim solution for disinfection, and then lay them flat in the sowing furrow of the second container, with the seed stem spacing 5-8cm and covered with a 5-6cm thick substrate.

[0050] By selecting good seed stems, we can ensure that the growth of Houttuynia cordata can get a good start and avoid it from suffering from more insect pests.

[0051] As an optional implementation, the specific steps of step 2 include:

[0052] When watering for the first time, irrigate with clean water until the substrate is completely moistened; then water once in the morning and once in the evening every day until new buds appear.

[0053] As an optional implementation, after completing one harvest of Houttuynia cordata, the first container and the second container are placed in a cool indoor place and supplemented with light appropriately, and the next harvest of Houttuynia cordata can be carried out after 2-3 weeks. This arrangement greatly increases the yield of Houttuynia cordata.

[0054] As an optional implementation, the second container is a layered automatic water-absorbing flower pot.

[0055] The specific steps of step three include:

[0056] The nutrient solution is irrigated once until it is just high enough to submerge the second layer of insulation by 1-2 cm. Later, the nutrient solution is supplemented according to the liquid height of the nutrient solution and the number of leaves of the Houttuynia cordata.

[0057] Through such an arrangement, the potted soilless cultivation technology is introduced into the field of Houttuynia cordata cultivation and the layered automatic water-absorbing flower pots are used for cultivation, making it have edible value and practical value for easy harvesting, as well as ornamental value.

[0058] As an optional implementation, the planting method further includes controlling the relative humidity of the air in the planting area to be no more than 85% and no less than 60%, and controlling the temperature in the planting area to be 16-25° C. Such an arrangement can prevent the occurrence of most Houttuynia cordata diseases.

[0059] As an optional implementation, when the leaves of Houttuynia cordata are burned or yellow, the leaves are cut in time to control the number of leaves and ensure that the humidity of the leaves is not too high. This is because timely supplementation of sunlight and control of the number of leaves can effectively reduce leaf diseases of Houttuynia cordata.

[0060] As an optional embodiment, the diameter of the second container is 14-16 cm; the number of seed stems sown in the second container is 2-3. This configuration is based on the consideration that if more seed stems are sown, when the seed stems are fully grown, the space in the second container will be insufficient, which will affect the absorption of nutrients by the Houttuynia cordata. The number of seed stems sown is 2-3, which just meets the growth needs of the Houttuynia cordata and has a gratifying yield.

[0061] It should be noted that the main principle of the present invention is an eco-friendly production model, and taking practicality and convenience as the priority, using fertilizers in a timely and appropriate amount, not wasting resources, avoiding the use of chemical pesticides as much as possible, and reducing excessive investment and use of various resources.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
