Cultivation techniques of Fructus euphratica

Lespedeza is planted in most areas of our country. Its roots are heat-clearing and detoxifying drugs, cure sores, snake wounds, etc., and have high medicinal value. Today we are going to learn about the cultivation techniques of Lespedeza.

growth habit

Lespedeza drought-tolerant, barren, acid-tolerant, saline-tolerant, mowing-tolerant. Strong adaptability to soil, in barren new land can grow, but most suitable for loam and humus soil. Cold tolerance is very strong, in the dam on the cold area to the main rhizome axillary bud winter, in the next year in late April germination of new branches, July to August flowering, September to October seed maturity, cutting period for June to September, regeneration is very strong, can be cut 3 to 4 times a year.

propagation method

seed

Seed treatment should be carried out before sowing. 3 days before sowing, soak seeds with "two open and one cool" hot water (that is, with 2 parts of boiling water and 1 part of cold water, when the water temperature drops to 50℃, stir the seeds while pouring water). After soaking for 24 hours, take it out, put it in the basket, and germinate under the condition of maintaining a certain temperature and humidity. When the seeds are split 1/3, they can be sown. Generally, they are sown in furrows, starting at 20-30 cm, covering 0.5-1 cm with soil, and sowing amount per mu is 2 kg.

cuttings

Select thick 0.5-1 cm sprout, cut into about 20 cm cuttings, autumn or early spring cuttings can be.

cultivation techniques

seed collection

9-10 Month, when the pod brown can be collected. Seed collection method is generally hand rubbing, collected pods after drying, rub off the fruit handle, remove impurities, bagged storage in a dry and ventilated place.

Land selection and preparation

The selective sandy loam soil is better for seedling field. To turn deep, generally not shallower than 30 cm. Turn over and make beds or beds for sowing.

transplanting

On sloping land with soil erosion, horizontal ditch and horizontal terrace soil preparation shall be adopted for planting. Choose healthy seedlings with good roots. Seedlings should be cut dry planting, hole planting. Hole diameter 30 cm, 30-50 cm, planting 1-2 seedlings per hole, watering and covering soil to preserve moisture after planting.

singling

The seedling height is 6-10 cm, and the seedling spacing is about 20 cm. 1-2 plants per hole.

topdressing

N and P fertilizer were applied after seedling setting. Ammonium sulfate 5-10kg/mu, calcium superphosphate 5kg/mu, can accelerate the growth of seedlings.

weeding and loosening

The first time weeding can be carried out after seedling emergence. It is better to remove it shallow, not too deep. After depending on the weed situation again remove 1-2 times can be.

drainage irrigation

Keep wet at seedling stage; seedlings are not tolerant of waterlogging. Pay attention to drainage.

stumping

2-3 In the year, it is necessary to carry out stubble cutting to promote its growth and development.
