High-yielding cultivation techniques of Rabdosia paniculata

Cat claw grass, alias small buttercup, three loose grass and so on. The underground root is used as medicine, which has the effect of detoxifying and dispersing knots. The main treatment is tuberculosis, tuberculosis of lymph nodes, pharyngitis, cancer and other diseases. It mainly produces Anhui, Jiangsu, Zhejiang, Henan, Guangxi and other provinces and regions.

The morphological characteristics are perennial herbs of Ranunculaceae. Tuberous roots several, nearly spindle-shaped. Underground there are most fibrous roots and spindle-shaped roots, which are shaped like cat claws, so it is called "cat claw grass". Stem slender, 5-17 cm tall, sparsely tomentose, glabrous. Basal leaves tufted, long-stalked, Ternate, or simple, 3-lobed to 3-divided, leaf blade 0.5-1.7 cm long and 0.5-1.5 cm wide, leaflet sessile, orbicular or Obovate, middle leaflet larger, apical dentate-lobed, base cuneate, sometimes basal leaflet 1-lobed or lobed into linear lobes; cauline leaves sessile, smaller, usually 3-parted into linear lobes. Flowers yellow, 1-1.5 cm in diam.; sepals to 3 mm long, outside pilose; petals usually 5, also 6-8, Obovate or elliptic, with pouch nectaries at base. Achenes ovate, with a short and slightly curved beak, ca. 1 mm in diam. The florescence is from March to April.

First, growth habits: cat claws like warm climate, humid, semi-shady environment. Slightly resistant to cold and barren. The requirement of soil is not strict, but it is better to cultivate sandy loam with deep soil layer, loose and fertile soil and rich organic matter.

Second, soil preparation and fertilization: intensive cultivation of fields planted with cat claw grass. Combined with soil preparation, apply sufficient basic fertilizer: 5000 kg of soil miscellaneous fertilizer, 50 kg of cake fertilizer, 20 kg of urea and 50 kg of phosphorus and potassium fertilizer per mu. Then make a 1.3-meter-wide and high bed, waiting for sowing.

Third, sowing: the cat claw grass is propagated with seeds, which is divided into two steps: seedling raising and transplanting. It can also be propagated with tubers. The sowing time is divided into spring sowing and autumn sowing. Spring sowing before and after the Qingming Festival, autumn sowing before freezing. Raising seedlings: first open a shallow ditch on the finished border surface, and then spread the seeds evenly into the ditch, cover soil, water, preserve soil moisture, cover grass, in order to facilitate seedling emergence. And strengthen the management, can be transplanted to the field after one year of cultivation. The sowing rate is 2 kg per mu. Transplanting: choose overcast and rainy weather, plant the cat claw grass on the whole border surface according to the row spacing of 15 × 10 cm, water and preserve soil moisture, in order to survive. Tuber propagation: one-year-old cat claw grass tubers were selected as propagation materials and planted on the whole border surface according to the row spacing of 20 × 10 cm. Watering to preserve soil moisture, in order to survive.

Fourth, field management: after the cat claw grass seedlings, pay attention to ploughing and weeding. Water in time in dry weather, pay attention to drainage in cloudy and rainy weather. The Beginning of Autumn should be topdressing once: 5 kg of urea and 10 kg of potassium dihydrogen phosphate per mu. Cat claw grass is a dormant period from early May to late September. In order to improve the land utilization rate, it is appropriate to intercropping fast-growing vegetables and other crops to increase income.

Fifth, pest control: cat claw grass diseases and insect pests are less, if diseases and insect pests are found, they can be controlled according to conventional methods.

Harvest and processing: cat claw grass can be harvested after growing with tubers for one year. Those who propagate with seeds must grow 2Mel for 3 years and then dig. The mining time is mainly in spring and autumn. The tubers dug out from the cat's claw grass are removed from the soil and fibrous roots, dried in the sun and then sold as medicine. The yield is 100 kilograms per mu. As high as 150 kilograms.
