Embodiment Construction

[0016] A method for breeding Nanjing linden, characterized in that: Nanjing linden is propagated in five steps of seed collection, seed storage, seed germination treatment, cutting cultivation and transplanting;

[0017] Step (1) seed collection: when the seeds are mature, they can be collected, and after the seeds are collected back, the method of "spreading and threshing" is used for processing;

[0018] Step (2) seed storage: the storage of seeds usually adopts three methods of "ventilated and dry storage", "low temperature storage" and "moist sand storage";

[0019] Step (3) seed germination treatment: the seeds are soaked in water at 10 to 20°C for 4 to 6 hours, soaked in 0.5% potassium permanganate solution for 1 to 2 hours before sowing, and then multiplied by 30 by 15 Centimeters are used to sow seeds;

[0020] Step (4) Cuttage Cultivation: Utilize prior art cuttages in the slotting bed for the processed twigs, the slotting bed is bow-shaped, covered with a plastic fi...

Abstract

The invention relates to a propagation method for tilia miqueliana.The tilia miqueliana is bred through the steps of seed collection, seed storage, seed germination accelerating, cuttage breeding and transplanting.The probability of death of young tilia miqueliana saplings can be effectively reduced, and the effect of improving growth efficiency of the tilia miqueliana can be achieved.

Description

technical field [0001] The invention relates to a breeding technology, in particular to a breeding method of Nanjing Tilia. technical background [0002] Nanjing Tilia, one of the four major street trees in the world, is a native tree species for weather forecasting in Nanjing and more cities. It was not discovered until March 2005. It has extremely high value. Due to various reasons such as weak reproductive ability, Nanjing Tilia has become the focus Protected endangered tree species. The dormant period of Nanjing Tilia's seeds reaches two to three years. How to "awaken" the sleeping Nanjing Tilia seeds has become a "difficult problem" to save this endangered tree species. A few days ago, Professor Shen Yongbao of Nanjing Forestry University led the research team to successfully "overcome" this difficulty after more than three years of research, so that the dormancy of Nanjing linden seeds can be "released". Seeds that originally needed to be dormant for two or three yea...
