桧柏一般常采用冬贮春播。去年,我们采用了春季贮藏、冬季播种的方法。3月份将桧柏种子用温水浸泡24小时,然后消毒并混砂、贮藏催芽,采用地下挖坑埋藏,选择地势高、排水良好、土质疏松的地方挖坑埋藏种子。坑的深度为0.5米,在坑底铺一层粗砂,上面再覆一层细砂,然后将种子与湿砂,按1:3的比例混合堆放,上面用湿砂覆盖,坑上用土封好。3月份地温在1～2℃。经过八个月的埋藏催芽,当年11月初发芽。将发芽的种子播种在温室中的木箱里,采用点播,行距5cm、覆土厚 Cypress cypress usually used in winter storage. Last year, we adopted a method of spring storage and winter sowing. Cypress seeds will be soaked in warm water for 24 hours in March, and then sterilized and sand mixed, stored and germinated, underground pit digging, selection of high terrain, good drainage, loose soil digging buried seeds. The depth of the pit is 0.5 m. A layer of coarse sand is laid on the bottom of the pit. A fine layer of fine sand is covered on the bottom of the pit. The seeds are mixed with wet sand at a ratio of 1: 3, covered with wet sand, it is good. March ground temperature at 1 ~ 2 ℃. After eight months of burial germination, germination in early November that year. The germinated seeds were sown in a wooden box in a greenhouse using on-demand spacing of 5 cm, casing thickness
