Planting technology of five-clawed dragon

Five-clawed dragons, also known as vines and palm-leaf petunias, are perennial twining herbs of the genus Ipomoea. Many people think of them as crape myrtle or Lingxiao. They are all vine flowers and are parasitic on other plants. It can be cultivated as an ornamental plant, the rhizome can be used as medicine, with the effect of heat-clearing and detoxification, so how to plant it? Let's get to know it.

1. Land selection and preparation

It likes warm and humid climatic conditions and has strong adaptability to the environment, so it is suitable to be cultivated in sandy loam or loam with deep soil layer, loose soil and good drainage. After selecting the land, the soil should be ploughed many times in the autumn of the first year to make the soil fully weathered and mature, and then thawed in the spring of the following year, combined with ploughing and applying rotten organic fertilizer as base fertilizer, 1500-2500 kg per mu. After shaping and raking flat, make beds and drainage ditches, and plant in other places.

2. Methods of reproduction

The seeds it uses in production propagate, harvest mature seeds from September to October in autumn, remove impurities and store them, and then sow them in April of the following year. By using the method of hole sowing, the holes were opened according to the row spacing of 25 × 35 cm on the border surface, the seeds and plant ash were stirred evenly, then sown, covered with a layer of fine soil and watered. If the temperature is too low, you can also cover a layer of straw or straw, heat preservation and moisturizing, in order to facilitate seedling emergence.

3. Field management

When the seedlings are unearthed, the cover grass should be removed in time, properly watered to keep the soil moist, to facilitate the growth of seedlings, when the seedlings grow to 10-12 cm, time seedlings, replenish seedlings, and leave 2-3 strong seedlings in each hole. When the stem vine of the plant grows to about 1 meter, it is necessary to build a support to make it entwined and grow. During this period, it is best to cut weeds by ploughing and weeding 3-4 times a year. In spring and summer, human and animal manure should be applied to promote plant growth, and barnyard manure, compost or cake manure should be applied in winter to facilitate its overwintering.

4. Pest control

The five-claw dragon has strong environmental adaptability and few diseases and insect pests, mainly caused by rust and powdery mildew, which mainly occur in spring and summer. The two diseases mainly harm the stems and leaves of the plant, and when serious, it will lead to plant death. Rust can be controlled by spraying trimethoprim, and powdery mildew can be controlled by spraying carbendazim, carbendazim, chlorothalonil and so on.
