Seedling breeding method of syzygium hancei

Abstract

The invention discloses a seedling breeding method of syzygium hancei. The seedling breeding method of the syzygium hancei comprises the following steps of obtaining seeds from November of every year to February of a second year, and sowing the seeds and breeding seedlings in a greenhouse from February to March of the second year; carrying out whole-course sun-shading treatment on the greenhouse during a seedling breeding period, enabling the illumination intensity to be 100lux to 300lux, applying a fertilizer once when 3 to 4 true leaves sprout on each seedling, afterwards, applying the fertilizer once week and week about, and after the seeds are sowed for 3 months, and when the heights of the seedlings reach 5cm to 7cm, transplanting the seedlings into nutrient bags; preparing nutrient soil, loading the nutrient soil into the nutrient bags, spraying a disinfector, carrying out atomization treatment after the seedlings are transplanted into the bags, then carrying out the sun-shading treatment, and enabling the illumination intensity to be 100lux to 300lux; after the seedlings are transplanted for one week, applying a urea aqueous solution to the seedlings, applying the urea aqueous solution in a spraying manner once every month, not stopping applying the urea aqueous solution until October of the second year, shading sun until February of a third year, applying a compound fertilizer aqueous solution once every month, transplanting the seedlings out of a nursery for forestation when the average heights of seedling plants are 100cm to 120cm until May of the third year. A scientific seedling breeding technique is adopted for the seedling breeding method of the syzygium hancei; the germination rate and the planting percent of the seeds of the syzygium hancei are obviously improved.

Description

technical field [0001] The invention relates to the technical field of seedling production and breeding, in particular to a method for raising seedlings of rose apples with red scales. Background technique [0002] Rose apple with red scales is an evergreen tree with bright red twigs and leaves. It is produced in Fujian, Guangdong, Guangxi, Hainan and other provinces and regions. It likes warm and humid climate. It has no strict requirements on soil and is salt-tolerant. Alkali, hard material, good wind resistance and other excellent ecological characteristics. The red-scaled rose apple monsoon forest used to be an important zonal vegetation type in the Beibu Gulf of Guangxi, but now it only covers less than 20hm in the coastal section of Fangchenggang City 2 The remains of the "feng shui forest". Red-scaled roseberry is an important windbreak tree species in the coastal zone of Guangxi, which is of great significance to coastal vegetation restoration and ecological enviro...

Problems solved by technology

At present, the artificial cultivation of rose apples is mainly based on seed propagation, and the conventional seed propagation has a low germination rate and few seedlings
