So how to plant the mountain dragon? Let's have a look with the editor.

1. Land selection and preparation

Mountain dragons are often wild in hillsides, forest margins, weeds and shrubs, and the requirements for soil are not strict, but it is appropriate to choose sandy loam or hillside land with loose and fertile soil and good drainage, followed by loam and clay loam, and sloping land can also be planted. The growth of Chuanshanlong is relatively large, so it is necessary to supply sufficient fertilizer when planting, and before planting, it should be combined with soil preparation, apply base fertilizer, base fertilizer is mainly organic fertilizer, spread it on the ground, plough it deeply and turn the fertilizer into the soil.

2. Sowing seeds

Before sowing, the seeds must be treated at low temperature in order to break the seed dormancy and improve the germination rate, so generally at the beginning of February, the seeds and fine sand are stirred and placed in an indoor environment below 10 degrees for 7-10 days and frozen in a pit. After Ching Ming Festival, you can sow seeds, adopt the method of strip sowing, trench the border by 10 cm apart, spread the seeds evenly into the ditch, cover 2 cm branches, water them after a little suppression, and often keep the soil moist until seedlings emerge. After watering, it can also be covered with grass to keep warm and moisturizing, and it can be removed when the seedlings emerge, about 5 centimeters of straw, and about 3 kilograms of seed per mu when sowing.

3. Colonization

Planting is carried out before sprouting in spring, generally using the method of ridge planting, the distance between ridges is 65 cm, and the distance between plants should be based on the number of years of cultivation. If the plant is planted for two years, the plant distance is about 15 cm, that is, the root segment is connected from end to end; for three years, the plant distance is about 20 cm, and the root segment head-tail distance is 5-10 cm. After planting, cover the soil 10-15 cm and water the roots once to facilitate the survival of the plant.

4. Field management

When the seedlings grow to more than 15 cm, it is necessary to wait for time for seedlings, the principle of interseedling is weak and strong, dense and sparse, and timely ploughing and weeding at the same time to promote root growth, so as to prevent weeds from seizing nutrients and growth space and affecting seedling growth. Weeding is carried out 2-3 times a year. After the seedlings should be fertilized once in time, 1000 kg of farm manure per mu should be applied, and the plant growth should be accelerated in the second and third years. At this time, topdressing should be done twice a year to ensure that the plants have sufficient nutrients to grow. When the seedlings grow to 20-30 cm, it is necessary to set up and draw vines in time to increase the permeability between plants and promote photosynthesis.
