Seeding propagation method of sassafras

Abstract

The invention discloses a seeding propagation method of sassafras. The method comprises steps as follows: (1) land preparation: acid latosolic red soil land is used as seeding nursery land, deep ploughing is performed, and shallow turning, raking and bed making are performed after composted farmyard manure and calcium superphosphate are applied; (2) seed picking: manure fruits on sassafras trees are picked, peels are twisted away, seeds are obtained after cleaning, the seeds are degreased and rinsed clean with plant ash and placed in a shady, cool and ventilated place for drying, and seeding is begin after germination acceleration; (3) seeding: ditching and seeding in drill are performed on the bed surface, earthing up is performed after seeding, and the bed surface is covered with straw; (4) seedling management: soil of the bed surface is kept moist after seeding, weeding and soil loosening are performed, the covering straw is removed, root cutting treatment is performed, clear liquid manure fertilizer is dressed, seedlings are transplanted into nutrition bags when the seedlings are 15-20 cm high, and the seedlings are taken out of the nursery and planted when the seedlings in the nutrition bags are higher than 30 cm. The method has simple steps and is easy to implement, and the germination rate and the seeding propagation survival rate of sassafras seeds are increased.

Description

technical field [0001] The invention relates to a method for sowing and propagating trees, in particular to a method for sowing and propagating sassafras, and belongs to the technical field of agricultural tree cultivation. Background technique [0002] Sassafras, also known as Nan'an, Xianghu, Xianghu, etc., belongs to Ranunculaceae and is an evergreen tree of Lauraceae. The leaves can be used to raise celestial silkworms. Preliminary analysis of the leaves contains 3.1% crude protein and 1.9% crude fat. The celestial silk can be used to make fishing line , strings, clothes brushes, etc.; branches, leaves, roots, bark, and wood can be used to steam camphor oil and extract camphor. Camphor oil is an indispensable raw material for blending various flavors. Camphor is mostly used in medicine, so it is widely used in industrial medicine. , chemical industry; the fruit stone is also high in fat, the oil content of the kernel is 60%, and the oil can be used for making soap; sassa...

Problems solved by technology

[0003] But at present the seeding propagation process of sassafras is complex and diverse, not easy to implement, the germination time of sassafras seeds is uneven, the germination time is long, and the germination rate is low, and the sassafras camphor survival rate of sowing is not high, can not satisfy market demand, simultaneously, waste The breeding time of the sassafras virtually increases the cost of breeding
