1. Site Selection The nursery should be chosen in paddy fields or hillside plots with convenient irrigation and drainage. Plots where tobacco, hemp, tuber crops, or vegetables were previously grown should not be used as nurseries to avoid root-knot nematodes. 2. Seedbed Preparation After the nursery site is deep-plowed and the soil is harrowed and broken up, seedbeds are made 10-15 cm high and 100 cm wide, oriented east-west, with length determined by the terrain. The ditch between seedbeds is 40-50 cm wide. Apply 1-2 tons of decomposed stable manure per mu, mix thoroughly with the seedbed soil and level it, then spread a layer of 5

1. Site Selection

The nursery should be chosen in paddy fields or hillside plots with convenient irrigation and drainage. Plots where tobacco, hemp, tuber crops, or vegetables were previously grown should not be used as nurseries to avoid root-knot nematodes.

2. Seedbed Preparation

After the nursery site is deep-plowed and the soil is harrowed and broken up, seedbeds are made 10-15 cm high and 100 cm wide, oriented east-west, with length determined by the terrain. The ditch between seedbeds is 40-50 cm wide. Apply 1-2 tons of decomposed stable manure per mu, mix thoroughly with the seedbed soil and level it, then spread a layer of 5-6 cm thick crushed yellow-red subsoil on top and compact it.

3. Building a Shade Structure

It is best to use a tall frame about 1.8 m high for whole-nursery shading. The shading material on top of the frame can be made by weaving rice straw, sugarcane leaves, Dicranopteris fern, etc. The shading material should be evenly dense, with about 75% shade. At present, the most convenient method is to use a shade net with 75% shading.
