The invention provides a direct-
sowing quick-growing cultivation method of
Jatropha curcas L., which comprises the steps of digging cultivation holes with depth of 28-32cm and
diameter of 58-62cm, mixing a special compound
fertilizer, digging planting small holes with
diameter of 3.8-4.2cm and depth of 3.8-4.2cm in the surface soil at the center of the holes when
sowing, placing seeds in the planting small holes, and completely covering the small holes with fine soil; when the main stems of the seedlings are more than or equal to 50cm,
cutting off the main stems of the seedlings from the parts 34-36cm away from the ground; when the lateral branches of the first-level seedlings are more than or equal to 80cm,
cutting off the lateral branches from the parts 60cm away from the branches of the main stems of the seedlings; when the lateral branches of each levels are 2m high away from the ground,
pruning the high parts. By adopting the method, the technical problems of high cost, variable growth conditions, abnormal growth, and deferred flowering and fruiting of the existing forced seed
germination, nursery
seedling raising, and
seedling transplanting are overcome, management and artificial picking are facilitated, the method is simple, labor and
fertilizer are saved, the
Jatropha curcas L. grows well, quickly grows and is high in yield, and good economical benefit, social benefit and ecological benefit are achieved.
