Cultivation methods and precautions of Yunnan purple grass

1. Maintenance methods

1. Temperature: It does not have high requirements for the temperature of the maintenance environment. The minimum temperature cannot be lower than ten degrees, and the maximum temperature cannot exceed thirty-five degrees. During this period, it can grow normally.

2. Watering: Water it thoroughly when it is dry, especially in the dry season. Water it fully each time. If it is rainy season, drainage needs to be done well to prevent the roots from being soaked in water for a long time and causing root rot. Its roots are very sensitive, and if they are kept in water for a long time, they are prone to root rot.

3. Fertilization: Before planting, 7,000 kg of animal manure is needed per hectare of soil. This is to ensure that it has sufficient nutrients in the early stages of growth. When the plant reaches the growth period, it needs to be fertilized once a month. The fertilizer should be a comprehensive and nutritious compound fertilizer.

4. Light: It can receive full-day sunlight. If it cannot receive full-day sunlight, at least six hours of light per day must be guaranteed.

2. Breeding techniques

1. Reproduction: It can be propagated by sowing, and the sowing time is divided into autumn sowing and spring sowing. The time for autumn sowing is November. Spread the seeds evenly on the soil, cover with three centimeters thick soil, and then press it slightly. Seedlings will emerge in about ten days. If the seeds are sown in spring, they must be treated with low temperatures so that the embryos can develop more maturely. If dry seeds are sown, the plants may not germinate that year. After the seeds are prepared, sow the seeds evenly in shallow trenches with a row spacing of 15 cm and cover them with soil.

2. Filling the seedlings: During the seedling stage of the plants, it is necessary to check for gaps and fill in the sparse areas with seedlings. Filling the seedlings should be done on rainy days or in the evening, and watering is required after filling.

3. Problem Diagnosis

1. Pests: The pests of Yunnan lithospermum include ants, cutworms, weevils, etc. They can be killed manually or by using poison bait.

2. Pathology: It is susceptible to leaf spot disease. After infection, irregular spots will form on the leaves of the plant. If found, the diseased plants need to be pulled out and destroyed in time, and then sprayed with Bordeaux liquid for treatment.

IV. Other issues

1. Edibility: It is not edible, but can be used as medicine.

2. Is it suitable for family breeding? It is not suitable for family breeding. Because it has certain medicinal properties, if it is accidentally consumed, it will have certain side effects, so it is not recommended for home breeding.
