Latest Paris polyphylla Planting Techniques and Management Methods Tutorial
Paris polyphylla is a plant in the Liliaceae family. The part commonly used as medicine is the rhizome of Paris polyphylla. The common types of Paris polyphylla are Yunnan Paris polyphylla or Paris polyphylla var. chinensis (Qiye Yizhihua). Paris polyphylla has certain medicinal effects. Paris polyphylla cultivation is suitable in the southwestern region, and it has certain requirements for the growing environment, so cultivation management also needs to pay attention to these aspects. Now let us learn about the cultivation of Paris polyphylla.
1. Seedling stage
Paris polyphylla generally needs to be raised as seedlings and then transplanted. Before sowing, the seeds are stratified with river sand to promote germination. After germination, sow the seeds. When sowing, pay attention to moisture retention, cover with moist fine soil, and keep moist until the seedlings emerge and before true leaves grow. No fertilizer should be applied because the root system is not yet well developed. After true leaves grow, lightly spray water and appropriately apply fertilizer solution. Once the growth height is reached, they can be transplanted. However, transplanting must be done at the right time; if too small, the roots are damaged, and if too large, the roots are also damaged.
2. Transplanting stage
When transplanting, pulling them out of the soil inevitably damages the roots, but root damage should be minimized as much as possible. They can be pulled out after watering more, or planted with some soil attached, so the roots are not easily damaged. Transplanting will have a seedling recovery period, a period of waiting for root growth to stabilize. At this time, water in the early stage and pay attention to topdressing in the later stage. Nitrogen, phosphorus, and potassium all need to be used in combination. The main goal is to greatly promote root growth.
3. Growth stage
During the growth stage of Paris polyphylla, temperature and moisture need to be controlled. For example, soil moisture should be around 40%, and about 2 cm of the soil surface should be moist. A temperature of at least above 12 degrees is more suitable. Low temperatures easily affect it, but during the growth of Paris polyphylla there is generally no low temperature. Drip irrigation or sprinkler irrigation can maintain moisture continuously. General open-field planting seasons are fine for temperature, from spring to autumn. During the growth stage, some farmyard manure can be applied.
4. Flowering and expansion stage
Flowering generally occurs from May to July. Flowering occurs in seasons with relatively high temperatures. At this time, note that if the temperature exceeds 35 degrees, it will be affected. During the flowering period, moisture can be appropriately reduced, but if the temperature is extremely high and the ground is dry, watering is needed. Fertilizer should be applied in advance before this, and both farmyard manure and nitrogen, phosphorus, and potassium fertilizers should be applied. Paris polyphylla has the characteristic of flowering while the rhizome expands, so at this time attention should be paid to nutrient supply and balancing the growth relationship between the two.
Paris polyphylla is a perennial medicinal plant with several types, and it has the characteristic of flowering and rhizome expansion proceeding at the same time. Therefore, based on these characteristics, the cultivation technique management work during the growth period should be determined. Or other matters.
