The Latest Complete Guide to Hairy Euphorbia (Dijincao) Planting Techniques

Dijincao, also known as Jianchou, Hongsicao, or Naijiangcao, is a plant of the Euphorbiaceae family. The whole plant can be used as medicine and has the effects of clearing heat and detoxifying, cooling blood and stopping bleeding, and draining dampness to relieve jaundice. It is widely used and is cultivated in most provinces of our country. So below, the editor will explain its planting methods.

1. Growth Habits

Dijincao prefers a warm and humid climate, tolerates slightly shaded environments, and has strong resistance to moisture. When planting, sandy loam or loam with loose soil texture, good fertility and water retention, and good drainage should be selected. It can also be intercropped with corn. If planting on wasteland, the land should be deeply plowed multiple times so that the soil is fully weathered. Then, according to the soil's fertility status, apply base fertilizer, mainly organic fertilizer. Spread it evenly on the soil, mix it evenly with plowing, and then make beds or ridges and wait for sowing.

2. Sowing

In autumn, from September to October, is the fruit maturation period of Dijincao. At this time, collect the seeds and fruits, dry them in the sun, take out the seeds, and store them for later use. Prepare to sow in the following spring from March to April. During sowing, in order to reduce the chance of pests and diseases, disinfect and sterilize the seeds. When sowing, mix them evenly with plant ash and then sow in rows. Open furrows on the bed surface at a row spacing of 15 cm, evenly scatter the seeds into the furrows, cover with soil, and gently press down with your hands.

3. Field Management

After the seedlings emerge, weeds should be pulled out in time to prevent weeds from affecting seedling growth. When the seedlings grow to a certain height, thin them in time, removing some weak and diseased seedlings and keeping strong seedlings. Each time weeds are removed, fertilizer can be applied once. The root system of the seedlings is not yet fully developed, so topdressing at the seedling stage should mainly use human and livestock manure water to promote seedling growth. If intercropped with corn, field management should be strengthened after the corn harvest to promote its peak growth period and increase yield.

4. Pests and Diseases

The main disease of Dijincao is sooty mold. Field management should be strengthened, appropriate close planting should be used, diseased branches and dense branches should be pruned in time to increase air permeability between plants. In summer during high temperature and rainy periods, reduce field moisture and drain water in time. When disease occurs, spray chemicals for control. Pests include piercing-sucking pests such as aphids, stink bugs, and psyllids, which can be controlled by spraying imidacloprid, trichlorfon, or dimethoate.
