Dig horizontal furrows on the ridges, with a row spacing of 30cm×(13-17)cm and a ditch depth of 17-20cm. There are two planting methods. One is the double-row planting method, which places the rhizomes in the ditch in an “eight-shaped” shape, with one row of buds facing right and one row facing left; the other is the single-row dense planting method, which places the rhizomes in a single row in the ditch, with one bud on the left and one on the right. After planting, cover with decomposed dry fertilizer, and then cover with a layer of fine soil flush with the ridge surface.
Disease and insect control
1. Diseases include gray spot disease, which harms leaves. Use 1:1.5:300 Bordeaux liquid or 3% Jinggang mold poison 5×10-5 liquid to spray. Rust disease, which harms leaves, can be sprayed with 25% triadimefon 1000 times liquid.
2. Pests include grubs biting rhizomes. Use 90% crystal trichlorfon 1000-1500 times liquid to irrigate the soil around the roots.
