Korean pine fruit-bearing forest cultivation method

Abstract

The invention discloses a Korean pine fruit-bearing forest cultivation method which comprises the following steps of (1) seed selection, (2) transplantation consisting of first-time transplantation, second-time transplantation, third-time transplantation and fourth-time transplantation and (3) irrigation, fertilization, weeding and harvesting after afforestation. The method has the advantages that the fruiting quantity of a Korean pine fruit-bearing forest is large, alternate bearing of naturally growing Korean pines is avoided, fruits can be borne every year, the economic benefit is good, a fruiting period is very long, so no cutting is needed, the ecological effect is guaranteed, economic foundation is ensured, and the protection of the ecological environment is facilitated.

Description

technical field [0001] The invention relates to a cultivation method for a Korean pine cone forest, in particular to a dwarfing and high-yield cultivation method for a Korean pine cone forest. Background technique [0002] Korean pine is a gymnosperm, evergreen tree, up to 40 meters high, with dense brown pubescence on branchlets, 5 leaves in bundles, thick and hard, 3 resin channels, and leaf sheaths falling early. The cones are ovate-conical, the apex of the scales is blunt, recurved outwards, the seeds do not fall off when mature, the seeds are large, 1.2-1.6 cm long, without wings, the seeds are used for food or medicine, and oil can be squeezed for food and industry use. The planting technology of existing Korean pine fruit forest has the following technical problems: Korean pine is to plant 4-year-old seedlings, and then grows freely. It does not produce fruit every year, and the number of fruit produced varies greatly each year. There are "big and small years", and ...

Problems solved by technology

The planting technology of existing Korean pine fruit forest has the following technical problems: Korean pine is to plant 4-year-old seedlings, and then grows freely. It does not produce fruit every year, and the number of fruit produced varies greatly each year. There are "big and small years", and the economic benefits are poor. At present, the Korean pine is used to make up for the economy, but it will affect the ecological effect.

[0003] In summary, there are technical problems that the naturally growing Korean pine fruit forests in the prior art have low fruit yield, are divided into "big and small years", and the economic benefits are poor. Logging Korean pine trees will affect the ecological effect.
