Embodiment 1

[0033] The first step, seed collection and modulation;

[0034] Harvest when the cones change from yellow-green to purple-brown, the pulp becomes soft, and the seeds change from milky white to yellow-brown. Crush the harvested cones and put them in water to wash them repeatedly to rinse off the peel, pulp and unfulfilled Seeds are dried for subsequent use to obtain prepared seeds;

[0035] In the second step, the prepared seeds are soaked in warm water with a temperature of 60°C to 80°C for 3 to 5 days for ripening;

[0036] The third step is to sow seeds;

[0037] At the beginning of July, the seedbed was first treated, including padding 15 cm of soil on the sandy ground, leveling the nursery, flooding, deep plowing after applying base fertilizer, and at the same time applying 30 catties of ferrous sulfate per mu to disinfect the soil; On the seedbed, the matured seeds are sown in holes at a row spacing of 15×15 cm, and the sowing depth is 1 cm;

[0038] The fourth step is ...

Abstract

A seedling method for Sabina vulgaris Antoine seeds comprises the following steps: step1, harvesting strobiles when color of the strobiles changes from greenyellow to puce, pulp changes to be soft, and the seeds change from ivory to tawny; crushing the harvested strobiles, scrubbing the crushed strobiles in water repeatedly, rinsing rind, the pulp and the non-full seeds, airing for use, and acquiring the prepared seeds; step2, performing ripening treatment for the prepared seeds; step3, treating a seedbed at first during July to August, that is, paving soil, 15 to 20 cm in thickness, on sand land and leveling and performing flooding irrigation for nursery land; carrying out deep tillage after applying base fertilizer and disinfect the soil simultaneously; then, hole-sowing the ripened seeds on the treated seedbed, wherein sowing depth is controlled to be 1 to 1.5 cm; step4, covering the seedbed after sowing is finished; step5, performing seeding stage management and pest control and prevention. The seeding method can improve the survival rate of a nursery seeding of the Sabina vulgaris Antoine, can be used for seeding cultivation and forestation on a large scale, and has important significance in the field of wind prevention and sand fixation.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for cultivating seedlings of Cypress sativa seeds. Background technique [0002] Sand cypress (Sabina vulgaris Ant.) is an evergreen coniferous shrub belonging to the Cupressaceae family, and is an excellent sand-fixing tree species. Existing methods that can be applied to the breeding of cypress seedlings are mainly realized by cutting and layering the root and stem vegetative organs of cypress. [0003] Due to the influence of factors such as the quality of cutting branches, the storage and transportation of cutting branches, the difficulty of controlling the depth of cuttings, and the proficiency of cutting personnel, the propagation of cutting cypress branches results in a low survival rate of cutting cypress seedlings; Breeding technology is suitable for the transformation and expansion of the original sandy Berlin, but not for large-scale nur...
