Method for facilitating cutting rooting of tilia miqueliana by magnetic treatment

Abstract

The invention provides a twig cutting method for tilia miqueliana. Twig cutting slips magnetic water treatment strength and frequency and external hormone treatment and cutting environmental conditions before cutting are strictly controlled, cutting rooting of tilia miqueliana can be achieved through steps of scion preparation, hormone treatment, magnetic water treatment, cutting and management after cutting, control over key links of twig cutting of tilia miqueliana is enhanced, magnetic treatment and external hormone act together to stimulate cutting slips to form callus tissue and root induction, the rooting environment is optimized, rapid rooting of the cutting slips can be guaranteed, meanwhile, rotting probability of the cutting slips can be reduced, the survival rate of twig cutting is above 85%, and good seedling basis can be built for seedling cultivation industrialization development of tilia miqueliana.

Description

technical field

[0001] The invention relates to the field of tree seedling propagation, in particular to a method for promoting rooting of Nanjing Linden cuttings by magnetic treatment. Background technique

[0002] Nanjing Tilia (Tilia miqueliana Maxim.), also known as Tilia miqueliana Maxim., is commonly known as "linden tree". Nanjing linden has a strong fragrance, thick leaves, and tall and straight trunks. It is a landscaping, medicinal, timber, and nectar plant. Because of its mysterious religious and cultural color, it has been introduced and cultivated in Japan in large quantities. Nanjing Tilia was once widely distributed as a native tree species in East China, but due to difficult reproduction and habitat destruction, its population and individual numbers have gradually declined. Research on reproductive technology has become a top priority for the protection, development and utilization of Nanjing Tilia resources!

[0024] A method for promoting rooting of Nanjing Tilia cuttings by magnetic treatment, the specific steps comprising:

[0025] 1. Collect branches and prepare spikes

[0026] In mid-to-late August, in the morning and evening or on cloudy days, choose semi-lignified branches of 1-2 years old seedlings as materials to make cuttings. The cuttings are 10-15cm long and 0.5-0.8cm thick, and one 1 / 2-1 Leaves, spikes truncate at upper end, obliquely truncate at lower end.

[0027] 2. Disinfection treatment of spikes

[0028] Use 1000mg / L potassium permanganate solution to elute the base 3-5cm of the spikes for 5 minutes, and then wash them thoroughly with clean water.

[0029] 3. Disinfection of cutting substrate

[0030] Perlite is used as the cutting substrate, and the cutting substrate is filled with a thickness of 25-35cm; one day before the perlite cutting, spray with 50% carbendazim wettable powder 600-800 solution and stir thoroughly.
