Embodiment Construction

[0019] 1. Seed picking

[0020] The best time for picking the seeds of pewter ash in Hubei area is from late September to mid-October of the lunar calendar every year, and the harvesting should be completed before the frost. After picking, it should be dried in time, and those with drying conditions should be dried in time. The degree of dryness of the seeds should be smooth and dry when held in the hand, or if you can hear the sound when you put it in a bag and manipulate it by hand.

[0021] Second, selection

[0022] Before seed soaking, in order to ensure its germination rate, seed selection should be carried out. Seeds with full grains and regular length should be selected for seed soaking preparation. The specific method is to select seeds with the naked eye, which must be operated by personnel with rich practical experience; the second is to soak the seeds in water and shave all the secondary species that are floating on the water surface. Generally, the ones that sink into ...

Abstract

The invention relates to a fraxinus hupehensis seedling cultivating method in field. The seedling cultivating method includes A, picking seeds; B, selecting seeds; C, digging a pit at first, paving fine yellow sand or white sand into the pit with thickness ranging from 4cm to 5cm, sowing a layer of seeds, paving fine sands onto the layer of the seeds with thickness ranging from 4cm to 5cm, sowing another layer of the seeds and circulating the procedures to complete seed soaking; after the seeds are sowed, keeping 83% to 87% moisture; and soaking the seeds at temperature of 15 DEG C to 20 DEG C for 10 to 12 months; and D, sowing the seeds. The seedling cultivating method has the advantages that germinating time is short and only takes nearly one year, germination rate is high, and survival rate is high.

Description

technical field [0001] The invention relates to the technical field of plant seedling raising, in particular to a method for growing seedlings of P. japonicus seeds in the field. technical background [0002] The couplet tree (Fraxinus hupehensis), also known as the couplet tree, is known as the unique living fossil of plants in the world. Only China has it in the world, China only has it in Hubei, and Hubei only has it at the southern foot of Dahong Mountain at the junction of Jingshan and Zhongxiang. It is a precious secondary tree species in the country (only in the dinosaur era), and it and Oleaceae (Oleaceae) are endangered in the world Extinct rare tree species, semi-deciduous tree. At present, it is being introduced and planted in the central, southern and coastal areas of my country, and its beautiful figure can even be seen in the United States, Canada, five Southeast Asian countries, Hong Kong and Taiwan. Its wood is very good, its dry branches are strong and si...
