Abstract

The invention discloses a cunninghamia lanceolata cultivation compound substrate and a preparation method for the same. The substrate comprises the following raw materials in parts by weight: 200 parts of cunninghamia lanceolata skin powder, 200-220 parts of tung bran, 0.1-1.2 parts of corn flour, 10-11 parts of rice bran, 0.07-0.08 parts of slaked lime powder, 0.04-0.05 parts of enzyme microorganism agent, 0.01-0.02 parts of suillus bovines agent, 0.01-0.02 parts of coletus luridus, 10-11 parts of calcium magnesium phosphate fertilizer, 2.0-2.5 parts of urea, and 0.01 part of 95% dexon wettable powder. The preparation method comprises the following steps of: crushing cunninghamia lanceolata skins, performing fermentation and adsorption treatments, performing ectotrophic mycorrhiza amplification, compounding, and thus obtaining the cunninghamia lanceolata cultivation compound substrate. With the adoption of the substrate, wood processing remains can be adequately utilized, thus being environment-friendly and reducing seedling culture cost; the use of quick-acting fertilizers and pesticides is reduced, thus reducing pollution, avoiding soil hardening and salinization, enhancing the biological activity of soil system, and building up fertility; seedlings are fast in growth, nursery stocks are good in quality, and the survival rate of afforestation is high; and the substrate is good in economic benefits, social benefits and ecological benefits.

Description

Technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a composite substrate for cultivation of fir and a preparation method thereof. Background technique [0002] Cunninghamialanceolata (Cunninghamialanceolata) grows rapidly, has good quality, is easy to process, and has a wide range of uses. It is one of the important fast-growing timber species in South China. Guangxi's existing fir forests cover an area of ​​over 1.25 million hectares, and more than 500,000 acres of reforestation are reforested each year, requiring a large number of afforestation seedlings. [0003] Chinese fir produces a large amount of bark and sawdust during processing. The sawdust is mostly used to grow mushrooms, while the bark is completely discarded, causing a waste of resources. Some studies have found that bark powder can be used as a cultivation substrate. For example, the technology of raising Chinese fir in net-bag container seedlings is to use 60%...
