Method for cultivating seedling of silkwood

Abstract

The invention relates to the technical field of cultivating seedlings of silkwood, and specifically relates to a method for cultivating seedlings of silkwood, which comprises: firstly, collecting mature fruits from selected good mother silkwood, take out the seeds after removing sarcocarp, and lastly wash, select, and dry the seeds in the shade, and accelerate germination; select a warm and moist hinterland with loose and fertile soil and good water drainage conditions as a seedbed, remove grass on the seedbed, deeply plow, fertilize and disinfect the hinterland; after disinfecting the germinated seeds, sow the seeds on the seedbed, cover the seedbed with soil and watering; and transplant the unearthed seedlings to seedling-cultivating discs for water fertilizing, shading and managing for preventing insects in integration. According to the method provided herein, the time of selecting seedlings is shortened while maintaining good genetic properties of the seedlings; and the soil of the seedbed is disinfected with 40 percent of formaldehyde 50 times of liquid or 0.1 to 0.3 percent of potassium permanganate solution, thus improving the growth environment of the silkwood and greatly increasing the survival rate.

Description

technical field [0001] The invention relates to the technical field of plant seedling cultivation, in particular to a method for cultivating golden nanmu seedlings. Background technique [0002] Jinsinan, an evergreen tree species of Phoebe lauraceae, is naturally distributed in the western part of the subtropical evergreen broad-leaved forest area. The climate here is warm and humid, with an average annual temperature of about 17°C, an average temperature of about 7°C in January, and annual precipitation. 1400~1600 mm. Phoebe nanmu is a endangered species under the second-class national protection in my country. Since ancient times, golden nanmu has been a special timber for the royal family. In history, golden nanmu was specially used for the buildings and furniture of royal palaces and a few temples. The Ming and Qing dynasties strictly prohibited the use of golden nanmu in buildings other than the royal family, and its preciousness can be imagined. At present, golden ...

Problems solved by technology

Due to the logging and utilization in the past dynasties, this rich forest resource is almost exhausted. The existing forest stands are mostly artificially cultivated semi-natural forests and scenic protection forests. There are still a small number of large trees in temples, cottages, parks, courtyards, etc. , but the hazards of diseases and insect pests are serious, and they are also dying one after another. Due to the limited seeds of Phoebe nanmu, the reproduction speed is greatly restricted, and the current seedling raising methods are not mature enough, there is no special disinfection technology, and there is no systematic and complete seedling raising technology system. There is also no professional fertilization material, which directly affects the survival rate and growth rate of golden nanmu
