High-yield cultivation techniques of Crane Grass

Fairy crane grass, alias Longya grass. The whole herb of aboveground stems and leaves and underground root was used as medicine. It has the effect of stopping bleeding. Clinical treatment of hemoptysis, hematemesis, hematuria, dysentery and other diseases. Mainly produces Hubei, Anhui, Jiangxi, Sichuan and other provinces. Most of them are wild, and the artificial cultivation is in the experimental stage.

The morphological characteristics are perennial herbs of Rosaceae, 30cm to 60cm tall and densely villous. Odd-pinnate compound leaves alternate, with 5-7 leaflets, often with several small leaflets on the leaf axis; leaflets ovate, Obovate or long-elliptic, 3-6.5 cm long and 1.5-3 cm wide, margin serrate, pilose on both surfaces and compound petiole; stipules conspicuous, ovate. Flowers open in summer, yellow, many arranged in terminal or axillary racemes; bracts fine; flowers 0.6-1 cm in diam.; calyx tube cup-shaped, grooved outside, apical hooked bristles, calyx lobes 5; petals 5; stamens 10; carpels 2. Achene obconic, with persistent sepals.

First, the growth habit of crane grass likes a warm and humid environment. The suitable growth temperature is 20 ℃ and 30 min. The requirement of soil is not strict, but it is better to use sandy loam with deep soil layer and loose and fertile soil.

Second, select suitable fields for soil preparation and fertilization and cultivate them intensively. Combined with soil preparation, ∶ applied 3000 kg of soil miscellaneous fertilizer, 20 kg of urea and 50 kg of phosphorus and potassium fertilizer per mu. Then make beds and wait for sowing.

Third, sowing crane grass to propagate with seeds, but also rhizome reproduction. Sowing time is autumn sowing and spring sowing. Autumn sowing before freezing, spring sowing before and after the Qingming Festival, before sowing, use the floor to make a shallow ditch on the finished border surface, and then spread the seeds evenly into the ditch. Rake flat so that the soil cover without seeds, watering, covering the soil, preserving soil moisture, in order to facilitate the emergence of seedlings. The sowing rate is 3 kg per mu.

Fourth, in the field management, the seed coat of crane grass is thick and it is difficult to emerge seedlings, so covering measures must be taken to facilitate seedling emergence. There are two ways of mulching: one is to use agriculture as straw mulching. The second is to cover it with plastic film. After Crane grass seedlings, attention should be paid to ploughing and weeding. It is often watered in dry weather and drained immediately in overcast and rainy weather. Use topdressing once before and after freezing: 10 kg urea per mu and 5 kg potassium dihydrogen phosphate per mu.

Fifth, pest control Crane grass is mostly wild, if fewer diseases and insect pests are found, timely prevention and control according to conventional methods.

6. Harvesting and processing Crane grass is generally harvested from the post-autumn flower bud stage to the full flowering stage. When harvesting, plant all the roots on the ground and cut them off, or dig them out, dry them in the sun, remove the impurities, and then they can be sold as medicine. The yield per mu is 300 Mu and 500 kg.
