Root-burying seedling breeding method of sterculia nobilis

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...
