Problems solved by technology

The use of mycorrhizal inoculation technology to raise seedlings and improve the survival rate of afforestation has been highly valued by scholars at home and abroad, but this technology is used to transform young Pinus tabulaeformis forests with poor soil, and there are few reports at home and abroad so far.

Embodiment

[0013] General situation of the test site: The test site is located in the bully forest farm of Lingyuan City, Liaoning Province, which is a low mountain and hilly area, with an altitude of 530m, an annual average temperature of 7.9°C, an annual precipitation of 400-600mm, an annual evaporation of 1800-2100mm, and a frost-free period of 125 days. The texture is sandy loam, the thickness of the soil layer is 20-30cm, and the parent rock is sandy shale.

[0014] Test materials: See Table 1 for test strains. The preparation of the mycorrhizal fungus inoculum adopts the first-level slant strain, the second-level liquid seed liquid, and the third-level solid matrix expansion culture method.

[0015] Cultivation process of bad-tasting milk mushrooms: Take out the strains stored in the refrigerator, put them into the basic medium for cultivation to activate them, and the method is to pick the mycelia from the ultra-clean workbench that kills the good bacteria and kill the good bacter...

Abstract

The invention relates to a study in the aspect of promoting the growth of trees, in particular to a method for promoting the growth of young pinus tabulaeformis plantations. The method comprises the steps of mixing fungi with the soil after mixed culture, then inoculating pinus tabulaeformis seedlings into the soil after mixing, and further promoting the growth of pinus tabulaeformis. By adopting the method for inoculating into the soil with the fungi after the mixed culture, pinus tabulaeformis roots can be promoted to be infected by the fungi, and dichotomization can be formed; compared with forest tress without the inoculation of the fungi, not only the absorption area is increased, and more nutrients and water can be absorbed, but also the lifespan of ectotrophic mycorrhiza on root systems of the forest tress is longer than the ordinary non-mycorrhiza, and the effectiveness of the absorbing roots can be further prolonged. In addition, mycelial mantles of the fungi become a mechanical barrier for pathogen infection in root epidermal cells, thereby inhibiting the pathogen infection in the absorbing roots and further improving the disease resistance of the forest trees.

Description

technical field [0001] The invention relates to the research on promoting the growth of trees, in particular to a method for promoting the growth of Chinese pine plantations. Background technique [0002] Mycorrhizal fungi and trees form a symbiotic nutritional system, which not only has a variety of beneficial functions for trees, but also plays an important role in the process of material transformation and energy cycle in the entire forest ecosystem; especially in barren mountains, wasteland, arid and sandy areas, erosion For afforestation in land and other areas with poor soil and lack of mycorrhizal resources, mycorrhizal biological inoculation technology can play a huge role. [0003] Mycorrhizal fungi have the function of degrading complex mineral and organic matter in the soil and converting it into effective nutrients that can be absorbed and utilized by trees. The use of mycorrhizal inoculation technology to raise seedlings and improve the survival rate of affores...
