Extended data:
Nanmu seedlings grow slowly in the early stage and like humidity, so it is advisable to choose fertile and humid soil with short sunshine time, convenient irrigation and drainage as nursery land. The soil is sticky, the drainage is not smooth, and it is prone to root rot; If the soil is dry and short of water, the seedlings will not grow well and will easily cause burns.
After the seedlings are unearthed, they should be weeded, loosened, fertilized and irrigated in time. Because of the long sunshine time and high surface temperature in summer, seedlings on flat ground are easy to get sunburned and need proper shading.
Choose a shady nursery land, increase the density of seedlings appropriately, so that the bed surface can be covered to a certain extent, and avoid the burning of seedlings without shade. Thinning should be carried out in stages, with less quantity and more times.
