The invention belongs to the technical field of plant cultivation, including a Metasequoia cuttings factorization hydroponics method: (1) the selection and treatment of cuttings; (2) preparation of nutrient solution; (3) to construct a hydroponic system of plant seedling management; (4). Specific steps are: from 2 to 10 years of good growth of Metasequoia trees on the clipping length of about 10cm, containing 2 3 bud cuttings. The 1/3 in the root powder of 10g/L was soaked in 24h in the root powder solution, then soaked in water for 2 weeks and rooting under the dark condition. After 2 weeks, with the planting and planting basket is fixed in a hole cutting foam board, foam board will be placed in the hydroponic nutrient solution box Sheng, to ensure cutting 1/3 fully immersed in nutrient solution, given appropriate light, and control the Metasequoia growth temperature and oxygenation time in hydroponics. Change the nutrient solution every other week to monitor the growth of the cuttings in real time. After 2 months, the survival rate and the measurement of Metasequoia root number etc.. The results showed that the method of the invention of the Metasequoia hydroponic cuttings growth in good condition, the survival rate and rooting rate were higher. And the high survival rate after transplanting Metasequoia cuttings, beautiful tree.

技术介绍
水杉(Metasequoiaglyptostroboides)隶属杉科,为落叶大乔木,原产于我国,著名活化石植物,是国家一级重点保护植物。水杉性喜光,较耐寒,不耐阴,能耐40℃高温和-30℃的严寒,既可在土层深厚、肥沃、湿润的酸性土壤中生长,又可在轻盐碱性土壤中生长,特别是在土壤含水量较高的低湿土壤中生长良好。水杉生长快,树姿优美,春来羽叶青翠,入秋落英缤纷,是著名的庭院观赏树种,用于公园、庭院、草坪、绿地中孤植、列植或群植,常用作行道树。播种、扦插、嫁接、组培是植物繁殖的主要方式,而水杉以播种繁殖为主。由于水杉的结实年龄较晚,种子充实率很低,繁殖水杉俨然是一个难题。如今,国内外对水杉的栽培多采用不同成分、不同比例的有机和无机物质作为基质进行扦插繁殖,主要包括硬枝扦插、嫩枝扦插、一季扦插、多季扦插等,但扦插繁殖水杉插条成活率较低。洪建锋等研究发现在以沙为基质、清水处理水杉原生母树的枝条扦插实验中,插条成活率最高仅达到16.97%。水培是工厂化无土栽培的一种方 ...
