Key points of cultivation techniques of Abrus cantoniensis

Chicken bone grass has strong adaptability and lax requirements on soil, generally dry land (flat land, sloping land) can be planted, sandy loam is better, drought resistance, fear of waterlogging, planting land should be well drained and sunny.

1. Raising seedlings (it is suitable to sow from March to April in the Gregorian calendar), the seed coat of Rabdosia angustifolia seeds is smooth and hard, and must be treated before sowing, otherwise the germination rate is not high. Treatment method: mix the seeds with twice the amount of fine sand, use round wood in the mortar hole or bamboo tube for 20 minutes, or rub with hands for 30 minutes, sift the sand, soak the seeds in hot water for about 40 ℃ for 12 hours, put the swollen seeds into cloth bags or rags, cover rice straw with upper and lower cushions to promote germination for 2 days, and sprinkle with hot water every 8 hours. The nursery land should choose the land with better soil quality near the water source (half of the seedling land per mu), break the soil into pieces and level the soil, sow the germinated seeds and a small amount of fine sand evenly on the border surface, cover a layer of fine soil, and then cover a layer of straw or leaves (the grass should be thin so that the table should not be seen). It is best to build a scaffolding on each bed, about 2 feet high, covered with branches or weeds to prevent sun exposure or heavy rain from interrupting the seedlings. The seedling ground should always be drenched with water to keep it moist. After the seedlings come out, the weeds on the shed are gradually removed to make them transparent. Miao Gao applied human and animal dung water once every 2-3 hours.

2. Transplanting: the seedling height is 4 to 5 inches, which can be transplanted in overcast and rainy days, open ditches or beds, move the seedlings into the ditch or hole, fill and compact, and fix the root water, and the plant row spacing is 20 × 30 cm.

3. Management: 15 days after transplanting, loosen the soil and apply fertilizer once, apply 10 piculs of human and animal manure or 10 jin of urea (1 jin of urea per 100 jin of water). Fertilize once more after a month, and it is better to apply compound fertilizer deeply. When the main seedling grows to 7-8 inches high, remove the terminal bud to increase the yield. The ruler may be drenched or irrigated in dry days, and pay attention to drainage in rainy days to prevent stagnant water from rotting the roots. It is best to spray foliar fertilizer for 3 times from August to September. When the conditions permit, it is best to insert a hedge pole between the two plants to let the vine climb up because the chicken bone grass is a light-loving multi-branched vine, and the construction is beneficial to its growth and increase its yield.

4. Pest control: diseases and insect pests are mainly leaf blight. Methyl topiramate or Kangkuning can be sprayed when the disease occurs. Insect pests are sprayed with dimethoate (do not use other highly toxic pesticides, especially near harvest).

5. Harvest: harvest around the end of November, dig out the roots, wrap it into a figure of 8, and dry it in the sun, generally yielding 20000kg of medicinal materials (dried products) per mu.

Note: when there are conditions, it is best to use sulfuric acid to treat the seeds. The method is: seeds half a jin (95% sulfuric acid 500ml, mixed in a plastic box, stirring continuously with a wooden stick for 6 minutes (do not let sulfuric acid splash on skin and clothing), filter to remove sulfuric acid, rinse the seeds in clean water, then soak in 40 ℃ hot water for 8 hours, and then sow seeds, so that the germination rate is high and fast.
