Problems solved by technology

[0003] In the production process of Zhennan seedlings, in order to cultivate high-quality and strong seedlings, chemical fertilizers, pesticides, exogenous hormones, etc. are often used. Long-term use of these chemical substances will not only change the soil properties and destroy the soil structure, but also cause great damage to the environment. Pollution weakens the stress resistance of seedlings, resulting in a long time for slow seedlings after transplanting and low survival rate

Embodiment 1

[0019] Choose sandy loam soil with a pH of 6.2 and good drainage as the seedbed, apply 2,000 kg of organic fertilizer mixed with pig manure and magic mushroom leftovers, and 60 kg of superphosphate per acre. Use a rotary tiller to plow the ground and manually level it. . Open the box according to the width of 120 cm, soak the soil of the seedbed with 1% potassium permanganate solution, and then cover it with black film for 7 days.

[0020] Select zhennan seeds with full grains, strong vitality and high germination potential, dilute them with 50% formalin at a ratio of 1:100, and then put zhennan seeds into the diluted formalin aqueous solution Soak for 30 minutes, take out and rinse the medicinal liquid with clean water, use formalin solution to sterilize and disinfect the zhennan seeds, so as to reduce insect damage during seedling cultivation. .

[0021] Then soak the seeds in 100㎎ / L gibberellin alcohol solution for 30 minutes, take out the seeds, and dry them at room temp...

Abstract

The invention discloses a mycorrhization seedling growing method of phoebe zhennan(Hemsl.)Yang. The method comprises the following steps of 1, selecting seeds, sterilizing and conducting acceleratinggermination; 2, conducting primary inoculating, wherein Pt mycorrhiza powder is uniformly mixed with flour to prepare a mixture, and the surfaces of the seeds selected in the step 1 are covered with the mixture to form pelleted seeds;3, selecting sandy soil of which the pH value is 5.8-6.5 as a seedbed, sorting the seedbed, digging striped furrows, and sowing the seeds in the step 2 into the furrows according to the spacing of 3-5 cm, and covering the furrows with soil; 4, conducting secondary inoculating, wherein 5 months after emergence, shallow ditches are dug among the striped furrows, thePt mycorrhiza powder is mixed with soil, the mixture is uniformly applied into the shallow ditches, and then the ditches are covered with soil. After the seeds of phoebe zhennan(Hemsl.)Yang are inoculated with a mycorrhiza agent, the seeds emerge early, the emergence rate and the plantlet formation rate are high, ectotrophic mycorrhiza formed by nursery stocks strengthens the absorbing capabilityof root systems, the absorption and utilization of nutritive elements in the soil are improved, the transplanting survival speed is high, and the survival rate is high; meanwhile, the mycorrhizationseedling growing method is easy and convenient to operate, low in cost and high in nursery stock quality.

Description

technical field [0001] The invention belongs to the technical field of zhennan seedling cultivation, and in particular relates to a method for zhennan mycorrhizal seedling cultivation. Background technique [0002] Zhennan is a large evergreen tree in the Lauraceae family. Zhennan grows slowly, and it takes hundreds of years to become a pillar. Due to logging and pest damage, the population has been reduced one after another, and the species have declined one after another. species. [0003] In the production process of Zhennan seedlings, in order to cultivate high-quality and strong seedlings, chemical fertilizers, pesticides, exogenous hormones, etc. are often used. Long-term use of these chemical substances will not only change the soil properties and destroy the soil structure, but also cause great damage to the environment. Pollution weakens the stress resistance of seedlings, resulting in a long time for seedlings to slow down after transplanting and a low survival ra...
