Rapid pinus bungeana seed processing, selecting, seeding and seedling method

Abstract

The invention discloses a rapid pinus bungeana seed processing, selecting, seeding and seedling method and belongs to the technical field of seedling cultivation. The method includes the steps of 1), performing seed storage at normal low temperature; 2), for soil preparation, broadcasting 4kg-quintozene per mu on early of middle of March, and applying organic fertilizer and superphosphate as base fertilizer after deep tillage; 3), for selection of seeds, disinfection and dormancy breaking, disinfecting and then soaking the seeds for 24 hours, and fishing out the floating seeds for sprouting; 4), for sprouting, mixing normal temperature water with sandy soil to serve as matrix, keeping the humidity to be from 50% to 60%, and after the seeds to be sprouted are mixed with the matrix according to the proportion of 1:3, and keeping the temperature to be from 18 to 23 DEG C for 18 to 23 days for sprouting; 5), for planting, performing dibble seeding on late March, covering with nutrient soil and spraying water every day; 6), seedling management; 7), disease prevention in middle and late periods. With the method, the emergence rate of the seeds can be increased, seedling ground, construction quantity and management cost are saved, and morbidity, death rate and composite cost are greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation and relates to a method for rapidly processing, selecting, sowing and cultivating pine seeds. Background technique [0002] White bark pine (Pinus bungeana) is an evergreen tree that grows slowly and can reach a height of 15 to 25 meters. It is one of the unique tree species in China. In recent years, white bark pine has been introduced to the United States, attracting worldwide attention. [0003] White bark pine is not as cold-resistant as Chinese pine, but it is more resistant to drought, humidity and soil than Chinese pine. Therefore, the market space for seedlings of white bark pine is wide. However, due to the lack of scientific seedling cultivation and management, white bark pine has a low seedling emergence rate and high mortality The problem brought certain difficulties to the users of white bark pine planting. Contents of the invention [0004] The purpose of the present...
