Planting techniques of seven-leaf and one-branch flower

In the first step of planting Paris polyphylla, seeds with full and healthy particles should be selected, mixed with sand and put into net bags for germination. Choose acid soil with good drainage as planting soil. When the seedlings grow up, transplant them in time according to the spacing of 10cm* 15cm, and pay attention to bring the original soil. Control watering and topdressing in time to prevent and control pests and diseases.

1. Pregermination treatment

Seed selection of Paris polyphylla is an important link in Paris polyphylla planting technology. To choose seeds with high maturity, generally choose seeds with healthy and full seeds and slightly wrinkled skin. After selecting the seeds, peel off the skin and expose them to the sun. In order to disinfect and improve the nutrient absorption capacity of seeds, it usually takes about 2 days. Mix the seeds and fine sand according to the ratio of 1:3, and put them into a net bag to keep the soil moist and free of water.

2. Acid Soil Heavy buildings need loose, breathable acid soil rich in organic matter. Before sowing, turn over the soil, dry and disinfect. Try to keep the soil clean and free of impurities, spread a layer of base fertilizer to level the soil, and sow it manually. After planting, the surface can be covered with a layer of rotten leaves and dead branches, and then watered.

Third, planting and transplanting

After the seeds to be sown grow into strong seedlings, they can be transplanted at the spacing of 10cm* 15cm. The transplanting time is generally selected in winter, and the root system enters the dormant period, which will not affect the transplanting process. Pay attention to the original soil cultivation, and the survival rate is high.

Fourth, the management of newly transplanted seedlings after planting should pay attention to shading and avoid strong light. Generally speaking, it is appropriate to use 40% light during the growing period. Loosen the soil from time to time to avoid soil hardening affecting growth. When weeding, attention should be paid to manual pulling as far as possible to avoid damaging the root system of seedlings.

The disease of seven leaves and one flower is mainly root rot, which is caused by excessive water and accumulated water. It is found that drainage measures should be taken immediately, and the roots should be watered after mixing with Tu Lv, Le Hui and Chun Lei Wang Tong according to the ratio of 1:2:4.

Five, water and fertilizer control

The growth period of seven leaves and one flower is rainy season, and there is basically no need to water when there is a lot of rainfall. When the rainfall is excessive and concentrated, pay attention to drainage to avoid water accumulation, root rot and even diseases. When the weather is sunny and dry, irrigation should be combined with soil moisture and seedling growth.

Rhizoma Paridis is usually topdressing in spring and winter, and topdressing can be done once every season. Topdressing is most suitable in April in spring, and in winter, topdressing is between11-65438+late February. Generally, topdressing is the best after weeding and loosening the soil, so compound fertilizer is recommended.
