Embodiment 1
[0022] A method for rapid propagation of Quercus mongolica, including the following steps:
[0023] (1) At the beginning of May, choose the strong growing branches of the year to make cuttings, and choose the middle position of the branches to make cuttings, the cutting length is 9-12cm;
[0024] (2) Prepare cutting matrix. The cutting matrix consists of peat soil: vermiculite: perlite: coarse sand: nutritional supplement, and the volume ratio is 2:1:1:1:1. The coarse sand should be laid at the most In the lower layer, the nutritional supplements are produced by fermentation of non-diseased plants and microbial agents;
[0025] (3) Disinfect the base of the cuttings made in step (1), insert the mixture of 450mg / l IBA concentration and 2.2mg / l 6-BA concentration, soak for 1.5h, insert into the cutting matrix prepared in step (2), and pour Enough water, humidity 80%, 25℃;
[0026] (4) After cuttings are completed, prevent pests, check the seedlings after 15 days, and replant the unsurv...
Embodiment 2
[0030] The difference from Example 1 is that step (1) is at the end of May, step (3) is immersed for 2.5 hours, humidity is 85%, and temperature is 30°C.
[0031] The raw materials of the nutritional supplement include 150 g of Mongolian oak leaves, 250 g of straw, 2 g of Cellulomonas flavonoids, 2 g of Rhodopseudomonas palustris, and 2 g of streptomyces in parts by weight. The preparation method includes crushing the leaves and straw of Mongolian oak and adding Cellulomonas chrysogenum, Rhodopseudomonas palustris and Streptomyces spp. Atomized spray water to adjust humidity 55%, and fermentation at room temperature for 25 days.
[0032] According to the above method, in an agricultural planting base, 200 cuttings were made for cuttings. 30 days after cuttings, 181 cuttings were rooted and survived.
Embodiment 3
[0034] The difference from Example 1 is that step (1) is the end of June, step (3) is immersed for 2 hours, the humidity is 83%, and the temperature is 27°C.
[0035] The raw materials of the nutritional supplement include 200 g of Mongolian oak leaves, 300 g of straw, 3 g of Cellulomonas flavonoids, 3 g of Rhodopseudomonas palustris, and 3 g of Streptomyces in parts by weight. The preparation method includes crushing the leaves and straw of Mongolian oak and adding Cellulomonas chrysogenum, Rhodopseudomonas palustris and Streptomyces spp. Atomized spray water to adjust humidity to 60%, and fermentation at room temperature for 30 days.
[0036] According to the above method, in an agricultural planting base, 200 cuttings were made for cuttings. 30 days after cuttings, 184 cuttings were rooted and survived.
[0037] It can be seen from Examples 1-3 that the rapid propagation of Quercus mongolica using the present invention has a cutting survival rate of 85-95%.
