Artificial cultivation of Houttuynia cordata

Houttuynia also known as side ear root, leeks, stinky grass, scaly grass, dog ears, etc., for the three white Styracanthaceae leek perennial herb, cold, taste hard, with antibacterial antiviral, detoxification, with food Value and medicinal value.

1. Growth habits and environmental requirements Under natural conditions, they are often wild in the back-yin mountains, forest-edge roadsides, and ravine-edge grasses. Sex hi warm and humid climate, good growth in wet conditions, avoid drought, adapt to a wide range of temperature, underground stem overwintering, -10 ~ 0 °C will not freeze to death, the temperature at 12 °C when the underground stem growth and emergence, growth The previous requirement is 16 to 20°C, and the underground stem maturity requires 20 to 25°C. Houttuynia is hi moist and resistant to moisture, requiring soil moisture, and the field soil water holding capacity is 75% to 80%. The soil is slightly acidic, pH 6 to 7, and the soil requirements are not strict. The fertile sandy loam and humus loam are preferred, but the clay soil can also grow. Nitrogen fertilization is the main method of fertilization. Appropriate application of phosphorus and potash fertilizers results in the growth of underground stems with sufficient organic matter.

2. Select land for loose soil and fertility, convenient drainage and irrigation plots, such as using paddy fields, winter plowing, drying, per 667 square meters of organic fertilizer applied 2000 to 4000 kg, 25 kg of compound fertilizer, ploughing and leveling, The width is 1.3 to 1.5 meters and the height is 30 centimeters. The length is determined according to the topography. The distance between the grooves is 30 to 40 centimeters.

3. Planted Houttuynia cordata can be used for seed propagation, but multiplication with roots. Spring and autumn can be planted, but spring is better. The planting method can be used for seedlings or seedlings. The organic fertilizer is applied to the inside of a hole or a ditch, and the fine soil is covered with 2 to 3 cm. A pestless and thick underground stem is cut into a short section of 4 to 6 cm. Each section has 2 to 3 cm. 3 sections, lying flat in the planting hole or in the ditch, the plant spacing of 5 to 8 cm, and then covering the soil thickness of about 5 to 6 cm, such as dry soil can be sprayed with water, to keep the soil moist.

4. Fertilizer Houttuynia is dominated by nitrogen and potassium, but the amount of phosphorus is small, but it cannot be lacking. When the seedlings excavated about 3 centimeters high, the first time can be topdressing, 1 part of human feces and urine can be mixed with water 4 to 5 copies, plus 2% of the feces of urea pouring, mid-late production into a flourishing period The requirement for fertilizer is also relatively increased. The use of phosphorus and potash fertilizers on the basis of nitrogen fertilizer is guaranteed, and potassium fertilizer is particularly important for the formation of rhizomes.

5. Field management Houttuynia production should be combined with fertilization for cultivating and weeding. In the middle and later stages, field management must be strengthened. Wet soil should be maintained throughout the growing season, timely watering should be performed during drought, and water should be promptly removed during the rainy season. After weeding, ripping, and sealing, the joints are promoted and controlled, and the shoots and leaves are harvested in time when the shoots are too long; the stems and leaves of the shoots turn yellow, the leaves and stems are fine, and fertilizers are appropriately applied to promote tree growth. If you do not plant trees, you must remove the buds in time to avoid flowering and consume large amounts of nutrients.

6. Pest control The stems and leaves of Houttuynia cordata have fishy smell and few insect pests. The diseases include white shank disease and leaf spot disease. Control methods: 1 Choose a reasonable crop rotation, with paddy wheels as well; 2 Choose drainage and irrigation facilities, loose loose and fertile soil; 3 Strictly select seeds and remove sick stems. 4 Strengthen field management, pay attention to drainage during the rainy season, and pay attention to irrigation when the drought occurs; 5 At the beginning of the disease, choose mancozeb, chlorothalonil, thiophanate, etc. to spray or root.

7. Houttuynia cordata can be harvested for annual consumption. Spring and summer harvesting of stems and leaves, autumn and winter mining underground stems. The cultivated Houttuynia cordata can harvest 2 to 3 times of shoots. One week after each harvest, diluted human urine or biogas slurry may be added with appropriate amount of NPK fertilizer. When underground stems are harvested, they are left part or broken. When the temperature rises in the following year, sprouts are sprouted and timely management of weeding, loosening, thinning, and topdressing is carried out. This allows continuous production for many years.

Conjugated linoleic acid (CLA) is one of the essential fatty acids for human and animals, but it is unable to synthesize a substance with significant pharmacological effect and nutritional value, which is of great benefit to human health. A large number of literatures have proved that conjugated linoleic acid has the physiological functions of anti-tumor, anti-oxidation, anti mutation, antibacterial, reducing human cholesterol, anti atherosclerosis, improving immunity, improving bone density, preventing diabetes and promoting growth. In recent years, some clinical studies have proved that conjugated linoleic acid can increase physical consumption after entering the body, so it can effectively reduce body fat deposition in weight control.

D-Tagatose Powder is one of the sweeteners. We have other sweeteners. The effective component of Monk Fruit Extract is Mogroside. Mogroside is 300 times sweeter than sucrose and does not produce heat. It is a valuable raw material in beverage and candy industry and the best substitute for sucrose. Aspartame powder, in food and soft drinks, usually aspartame is 180 ~ 220 times sweeter than sucrose. Erythritol Powder, In general, the relative sweetness of aspartame was negatively correlated with the concentration of control sucrose, and varied with different flavor systems, pH, tasting temperature and the concentration of sucrose or other sugars. Erythritol is a kind of filling Sweetener, which is a four carbon sugar alcohol. The sweetness of erythritol is only 60% - 70% of sucrose. It has a cool taste, pure taste and no aftertaste. It can be combined with high times sweetener to inhibit the bad flavor of high times sweetener. We strongly recommend pregabalin Powder. It's the best product we sell.
