Breeding method of cinnamomum japonicum

Abstract

The invention relates to a breeding method of a cinnamomum japonicum. The method comprises: the steps of seed collection, wet sand stacking bud forcing treatment, seedbed preparation, sowing and seedling management are carried out; collected cinnamomum japonicum fruit is peeled and cleaned, and the processed cinnamomum japonicum fruit, wet sand layers and aired seeds are stacked and stored for future use; broken mountain soil is used as subsoil of the seedbed, basic fertilizer is spread on the subsoil, then fine mountain soil is used for covering the basic fertilizer and the surface is levelled; in the last third of January, the spared seeds are dibbled into the seedbed, after being covered by fine scorched clay dust, the seedbed is evenly covered by straw, then the seedbed is covered by a plastic film, the soil is used for pressing the plastic film around the seedbed, the surface of the seedbed is closed, a transparent and closed arched shed is built above the plastic film, and a bigtransparent and closed shed is arranged outside the arched shed; in the first third of March, the covering straw and the plastic film on the surface of the seedbed are uncovered; in the middle third of April, the small arched shed is removed after the temperature goes up; in the last third of June, a single layer of sunshade net with the shading rate of 60% is used for covering; the surface of the seedbed is kept humid in normal times; in the spring of the next year, nursery seedling comes out. Compared with the prior art, the method has obvious advantages of high rate of seedling emergence, quick growth of seedling, good economic benefit and the like.

Description

technical field [0001] The invention relates to a breeding method of woody plants, in particular to a breeding method of Putuo camphor. Background technique [0002] Putuo camphor (Cinnamomum japonicum var.chenii) is an evergreen tree belonging to the genus Lauraceae of the Lauraceae family. It is intermittently distributed in the eastern coastal islands of my country; it is also distributed in Korea and Japan, and it is only found in Zhoushan islands in Zhejiang. It is a unique species of Zhoushan islands and is concentrated in Zhoushan. There is no natural distribution of this tree species in Putuo Mountain, Zhujiajian Island and the adjacent Xuanshui Island in Putuo District, except Putuo District. Putuo camphor is a rare and endangered plant, and was listed as a second-class national key protected wild plant in the late 1990s. In recent years, with the increasing development of landscaping in our country, characteristic native plants have been more and more widely used i...
