Problems solved by technology

[0003] There have been many research reports on casuarina water-cultivated seedlings in China. The traditional casuarina hydroponics rooting culture is to use 50ppm concentration of casuarina acetic acid (naphthlcetic acid) to 2-3 months old Casuarina twigs or semi-lignified semi-lignified twig tips. acid) or indolebutyric acid (indolebutyric acid) solution for 24 hours, then rinse the soaked part with tap water, reinsert it into a culture bottle filled with tap water, place it in sufficient direct sunlight to induce culture, and replace the tap water every 24 hours until Until rooting, it usually takes about 2 weeks to take root smoothly (Liang Zichao et al., 1982; Ke Yuzhu et al., 2000), the time is too long

Embodiment 1

[0026] 1) Hydroponics of casuarina shoots

[0027] In June, the daily average temperature was 28.5°C, the illuminance was 3500LUX, and the measured number of plants was 200. On a sunny day, select the branches of the budding shoots of the mother plant of Casuarina equisetifolia, and select semi-lignified branches with a length of about 8-10cm. The best way to take buds is to pinch the buds by hand. Put the branches in water to soak and moisturize. After soaking, take out the buds, arrange the branches according to the head and tail, put the roots of the buds into a disposable plastic cup, it is advisable to fill each cup with buds, pour the prepared Concentration is 75mg / L IBA solution culture fluid, and culture fluid is advisable to be immersed in 40% above the root of branch. After 10 hours, take out the bud strips, wash the medicinal liquid with clean water, put the bud strips in each transparent plastic cup, put about 20 bud strips in each plastic cup, and place the bud s...

[0031] 1) Hydroponics of casuarina shoots

[0032] In December, the average daily temperature was 15.5°C, the illuminance was 2500LUX, and the measured number of plants was 200. On a sunny day, select the branches of the budding shoots of the mother plant of Casuarina equisetifolia, and select semi-lignified branches with a length of about 8-10cm. The best way to take buds is to pinch the buds by hand. Put the branches in water to soak and moisturize. After soaking, take out the buds, arrange the branches according to the head and tail, put the roots of the buds into a disposable plastic cup, it is advisable to fill each cup with buds, pour the prepared Concentration is 125mg / L IBA solution culture fluid, and culture fluid is advisable to be immersed in 40% above the branch root. After 14 hours, take out the bud strips, wash the medicinal liquid with clean water, put the bud strips in each transparent plastic cup, put about 20 bud strips in each plastic cup, and place the bud...

Abstract

The invention discloses a coast oak water planting seedling culturing method. The technology comprises the step of selecting variety and concentration of hormones, medicine liquor soaking time, coast oak budlings and the like for coast oak water planting seedling culturing. Different hormone concentration and soaking time are selected according to different seedling culturing time, so the optimal coast oak root forming number and quality are achieved, the root forming time is shortened, the survival rate of the seedling culturing is improved and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, in particular, the invention relates to a method for cultivating casuarina seedlings in water. Background technique [0002] Casuarina equisetifolia (Casuarina equisetifolia), Casuarina equisetifolia plant, about 35 species, native to Australia, Pacific islands, Malay archipelago and so on. Casuarina has been introduced to China for more than 80 years and has been cultivated in Guangdong, Guangxi, Fujian, Taiwan and the South China Sea. Casuarina is light-loving, heat-resistant, salt-alkali-resistant, and barren. The casuarina root system has nodules, which can fix nitrogen in the atmosphere. Casuarinas grows fast and has strong adaptability. Building casuarinas forests in coastal areas can not only prevent wind and sand fixation, protect farmland, increase crop yields, but also improve site conditions. [0003] There have been many research reports on casuarina water-cultivated seed...
