How many jin per mu can the yield of Thesium chinense generally reach?

Thesium chinense is a common grass found at stone ridge edges and in sandy grassland, also known as little grass and white milk grass, and has the effects of clearing heat and detoxifying and tonifying the kidney. It is currently widely used as a medicinal material, so how much is the yield of Thesium chinense per mu?

1. How much is the yield of Thesium chinense per mu?

The yield of Thesium chinense per mu is about 200 jin. If managed properly, one mu can produce more than 200 jin; if poorly managed, it may be more than 100 jin. To achieve a high yield of Thesium chinense, it is necessary to choose some loose, fertile soil rich in humus for planting. At the same time, sufficient base fertilizer should be applied before planting, and later work such as watering, fertilizing, and weeding should be done well.

2. How is Thesium chinense planted?

1. Land selection and preparation

Thesium chinense is suitable for growing in fertile, loose soil, so when selecting soil, try to choose sandy loam with sufficient fertility. After selecting the soil, deeply plow the soil, and apply 2500 kg of decomposed farmyard manure and 50 kg of superphosphate per mu. After shaping and leveling, make ridges or beds for later use.

2. Sowing and raising seedlings

(1) Propagation method: Thesium chinense can be propagated by direct sowing or by raising seedlings and transplanting.

(2) Seed selection: When the fruit matures from July to August each year, collect the seeds.

(3) Sowing time: Thesium chinense has two methods: direct sowing and drilling. Among them, direct sowing is carried out in mid-to-late April for spring sowing or in October-November for autumn sowing. Drilling is in March in spring.

(4) Sowing method: For direct sowing, open furrows at a row spacing of 20 cm, evenly drill the seeds into the soil, and finally cover with 1-2 cm of soil. Generally, 0.75-1 kg of seed is used per mu, and seedlings can emerge for transplanting after half a month. For drilling, cover with 1 cm of soil after sowing, keep the seedbed moist at all times, and control the temperature at 15-20 degrees. Seedlings emerge after about 10 days, and can be transplanted when the young seedlings grow to 6-10 cm.

3. Transplanting

(1) Transplanting time: Try to choose the afternoon after rainy days, when the survival rate is high.

(2) Transplanting method: Dig out the plants with soil and roots, and transplant them into the field at a plant and row spacing of 20×25 cm.

4. Management techniques after transplanting

(1) Weed frequently: If weeds grow taller than the plants, pull them out in time to avoid breeding pests and diseases and affecting the normal photosynthesis of the plants.

(2) Fertilizer requirements: Apply fertilizer once each in spring and winter every year, which can promote root growth and increase yield. Fertilization is mainly phosphorus fertilizer, applied at 20-25 kg per mu. During the peak growth period, a potassium fertilizer solution can be sprayed to improve the plant's disease resistance, which has a clear effect on increasing yield.

(3) Water requirements: Thesium chinense likes a dry environment. Apart from appropriate watering during the early seed germination stage and seedling growth stage, it does not need frequent watering in the later growth stage, so as not to affect its growth. After the rainy season, drain water in time to avoid root rot.

(4) Covering with wheat straw: For annual seedlings after loosening soil and weeding, or for seedlings grown for 2-3 years, after fertilizing and watering, cover with wheat straw or wheat bran, sawdust, and the like. This can strengthen the decomposition of microorganisms in the soil, maintain moisture, reduce weeds, and create a good growing environment for Thesium chinense.
