I. growth habits

Snake grass likes a warm and humid environment and is afraid of drought and waterlogging. The requirement of soil is not strict, but the sandy loam which is loose and fertile and rich in organic matter is better, but heavy clay and low-lying land should not be planted.

II. Soil preparation and fertilization

Select high-lying, well-drained fields and cultivate them carefully. Combined with soil preparation, apply sufficient basic fertilizer: 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 seeds

Snakeweed propagates with seeds. Division and transplanting were carried out in two steps. It can also be broadcast live. The sowing time is spring sowing. Before sowing, the seedlings were used to make a shallow ditch on the finished border surface, and then the seeds were scattered evenly into the ditch, covered with soil and watered to preserve soil moisture to facilitate seedling emergence. The sowing rate is 2 kg per mu. After the seedlings are collected, the field management should be strengthened and the seedlings can be transplanted after autumn. After transplanting in autumn, the seedlings of Agkistrodon acutus were planted on the whole border according to the row spacing of 20 × 10 cm. Watering to preserve soil moisture, in order to survive. Before the direct seeding, the grass was used to make a shallow ditch on the finished border surface, and then the seeds were evenly scattered on the whole border surface, and raked flat with a rake, so that the soil cover had no seeds. Water to preserve soil moisture to facilitate the emergence of seedlings. The sowing rate is 1 kilogram per mu.

IV. Field management

Pay attention to ploughing and weeding after finishing the seedlings of Snake Grass. Watering immediately in dry weather and timely drainage in cloudy and rainy weather. In the direct seeding field, when the seedling height is 10 cm, the seedling is fixed according to the row spacing of 20 × 10 cm. And topdressing once: 10 kg of urea and 10 kg of potassium dihydrogen phosphate per mu.

Prevention and control of diseases and insect pests

There are few diseases and insect pests in Snake Grass, if found, it should be controlled in time according to conventional methods. Underground pests are trapped and killed with octane scales and poison bait.

VI. Harvest and processing

Snakegrass is harvested in time after the fruit is ripe in autumn. The mature snake grass is cut off with sickle root, dried in the sun and sold in medicine. The yield is 300 kilograms per mu.
