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 fir cultivation composite substrate and a preparation method thereof. Background technique [0002] Chinese fir (Cunninghamialanceolata) grows rapidly, has excellent materials, is easy to process, and has a wide range of uses. It is one of the important fast-growing timber tree species in South China. The existing Chinese fir forest area in Guangxi exceeds 1.25 million hectares, and more than 500,000 mu of forests are renewed every year, requiring a large number of afforestation seedlings. [0003] During the processing of Chinese fir, a large amount of bark and sawdust are produced. Most of the sawdust is used to grow mushrooms, while the bark is completely discarded, resulting in a waste of resources. Some studies have found that bark powder can be used as a growing substrate. Such as: fir light matrix net bag container seedling cultivation technology, is to apply 6...
