Example Embodiment

[0024] Example 1

[0025] The seeds of Taiwania flousiana were purchased from Kunming in December 2012, and the seeds were used in a cloth bag device and placed in an air-conditioned room.

[0026] After the seeds are disinfected with a potassium permanganate solution with a mass fraction of 0.05-0.1%, they are sprayed with a poly-γ-glutamic acid gel material with a mass fraction of 28%, and they are naturally air-dried at room temperature and stored at a constant temperature of 17°C;

[0027] In March 2013, the seeds were soaked in 0.1% potassium permanganate solution for 30 minutes before sowing, washed with clean water, soaked with hot water at 40°C, cooled naturally, and soaked in water for 15 hours, rinsed and placed Intensify germination at 25℃ in germination machine;

[0028] On-demand the buds that have grown white spots into the light matrix medium, and control the on-demand depth to 1-2cm. After the on-demand is completed, spray water to control the indoor temperature of 28...

Example Embodiment

[0032] Example 2

[0033] The steps of this embodiment are the same as those in Example 1. The light substrate medium is 58.8 kg of coconut bran, 18.5 kg of peat, 2.8 kg of corn stover with a particle size of 120-200 mesh, 2.6 kg of sodium carboxymethyl cellulose, and 10.2 kg of humic acid. After 4 days of accelerating germination in the germination box, the seed coat cracked to reveal white bud spots. Each nutrient cup was spotted with 3 seeds, and the germination rate reached 67.8% after 20 days of spotting. The water and fertilizer control started at the end of 2011, and the average seedling height was 28.6cm at the end of December. The diameter reaches 0.32cm.

Example Embodiment

[0034] Example 3

[0035] The steps of this embodiment are the same as those in embodiment 1. The light substrate medium is 64.2 kg of coconut bran, 20 kg of peat, 2 kg of corn stover with a particle size of 120-200 mesh, 4.85 kg of acrylamide modified starch material, and 8.85 kg of humic acid. After 4 days of accelerating germination in the germination box, the seed coat cracked to reveal white bud spots. Each nutrient cup was seeded with 3 seeds. The germination rate reached 72.3% after 20 days of seeding. The water and fertilizer control started at the end of 2011, and the average seedling height was 26.4cm at the end of December. The diameter reaches 0.51cm.

Abstract

The invention discloses a breeding method for Taiwania flousiana non-woven fabric light-matrix sowing seedlings. The breeding method comprises the following specific steps: mixing coconut shell powder, peat, a water-retaining agent and humic acid to prepare a non-woven fabric light-matrix nutrition cup; soaking with a 0.1-0.5% of potassium permanganate solution for 30-60 minutes before sowing, washing with clean water, soaking seeds by using hot water with the temperature of 40-50 DEG C, changing water to continue soaking for 24-48 hours after naturally cooling, after the seeds are washed with clean water, placing the seeds in a germination accelerating machine for germination accelerating at the temperature of 25-30 DEG C; after white buds of the seeds come out, dibbling into the light-matrix nutrition cup, and covering with a thin film; spraying chlorothalonil for one time and covering with a sunshade net after Taiwania flousiana seedlings grow, fertilizing for one time every other 10-20 days after lateral roots of the seedlings penetrate the bottom of the cup, classifying the seedlings on a seedling tray when the height of the seedling is 5-10 cm, starting to carry out seedling hardening at the end of 2011, and outplanting after the seedling hardening. The Taiwania flousiana seedlings cultured on the light-matrix nutrition cup have developed root systems and are thick and strong, the transportation cost and forestation cost can be reduced as the matrixes are light, and light matrixes of plants which do not survive can be recycled; the germination accelerating rate is high, the germination consistency is better, and the seed germination rate of Taiwania flousiana seeds is effectively increased.

Description

technical field [0001] The invention relates to a breeding method of bald fir, in particular to a breeding method of bald fir seedlings sown with a non-woven light matrix nutrition cup. Background technique [0002] bald fir ( Cunninghamia lanceolata ) is Taxodiaceae (Taxodiaceae) genus ( Cunninghamia )plant. Bald fir is a subtropical tree species that is more light-loving. Like warm and humid, foggy and calm windy climate environment, intolerance to severe cold and damp heat, afraid of wind and drought. Adapt to the climatic conditions with annual average temperature of 15°C-23°C, extreme minimum temperature of -17°C, and annual precipitation of 800-2000mm. The cold resistance is greater than its drought tolerance, and the influence of water and humidity conditions is greater than that of temperature conditions. Afraid of salt and alkali, it has higher requirements on soil than ordinary tree species, and likes fertile, deep, moist, well-drained acidic soil. Shallow r...
