Embodiment Construction

[0012] Specific embodiments of the present invention will be further described in detail below. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0013] (1) Site selection and preparation

[0014] Choose a plot with a soil layer thickness greater than or equal to 0.8m, convenient irrigation and drainage, and sufficient sunlight. Burn to remove sundries in the nursery, and reclaim the entire site to make a seedbed. The width of the seedbed is 2m and the height is 30cm. The length is determined by the terrain and the plot. A trail is reserved between the seedbeds, and the trail width is 60cm. At the same time, apply 2kg of organic fertilizer per square meter of seedbed, the content of organic matter in the organic fertilizer is not less than 50%, the content of nitrogen, phosphorus and potassium (NPK) is not less than 5%, and 80g of nitrogen, phosphorus and potassium (15:15:15) compound ferti...

Abstract

The invention discloses a root-burying seedling breeding method of sterculia nobilis. The method comprises the following steps: choosing land and preparing soil, preparing seed roots, carrying out root-burying seedling breeding, disinfecting soil and carrying out seedling management. Through the adoption of the seedling breeding method provided by the invention, the seedling breeding period of thesterculia nobilis can be effectively shortened, excellent genetic genes can be retained, and the method has a high seedling rate when used for cultivation.

Description

technical field [0001] The invention relates to the technical field of forestry, in particular to a method for raising seedlings of Pingpo. Background technique [0002] Sterculia nobilis Smith (Sterculia nobilis Smith), Sterculia Linn (Sterculiaceae) is an evergreen fruit tree, arbor, also known as water hyacinth fruit and seven sister fruit. It is a traditional ornamental tree species with both dry and fresh fruits. It is often cultivated in gardens . There is a natural distribution in southern Yunnan, mostly in karst mountains. Pingpo is an important tree species with both ecological and economic benefits, and has great development prospects. Pingpo seeds are large, with a diameter of up to 2-3cm. The kernels are rich in starch, fat, protein, carbohydrates, vitamins, phosphorus, calcium, iron and other minerals. According to the measurement by the Key Laboratory of Yunnan Academy of Forestry Sciences, Pingpo fresh fruit contains 15.4% protein and 5.3% fat, which is sli...
