Embodiment Construction
[0017] Prepare Bacillus subtilis, Bacillus licheniformis and Bacillus amyloliquefaciens into different improvers according to Table 1, mix them with 1200g of alpine sphagnum peat with a water content of 15-30%, stack them separately, seal them with plastic film, and mark them separately CK (control group), A (Example 1), B (Example 2), C (Example 3), D (Example 4), and E (Example 5). After 25 days of fermentation, samples were taken to determine the pH value, total potassium, available potassium, total phosphorus, available phosphorus, organic carbon, ammonia nitrogen, bacteria, fungi and actinomycetes of the improved alpine sphagnum peat.

Abstract
The invention provides a method for preparing a camellia nitidissima sowing and seedling raising substrate, which comprises the following steps: collecting high-mountain sphagnum peat, draining until the water content is 15-30%, adding different doses of bacillus subtilis, bacillus licheniformis and bacillus amyloliquefaciens, uniformly mixing, respectively stacking, and fermenting and improving. Respectively marking as CK (control group), A, B, C, D and E; after fermenting for 25 days, sampling and detecting the pH value, total potassium, rapidly available potassium, total phosphorus, rapidly available phosphorus, organic carbon, ammonia nitrogen, bacteria, fungi and actinomycetes. And filling the improved high-mountain water moss peat into a 50-hole tray, sowing the rare plants, and measuring the germination rate of the seeds. The measured indexes show that the germination rate of the seeds is 96% or above after the high-mountain sphagnum peat is mixed with the bacillus subtilis, the bacillus licheniformis, the bacillus amyloliquefaciens and the bio-organic fertilizer for improvement, and the effect is optimal.
Description
technical field [0001] The invention relates to a seedling-raising substrate, in particular to the configuration of the golden camellia seedling-raising substrate. Background technique [0002] The substrate is the key factor that determines the quality of seedlings and even the success or failure of seedlings in rare plant sowing seedlings. A substrate with good physical and chemical properties can provide seedlings with stable growth media such as water, air, and fertilizer, thereby promoting the development of the root system of the seedlings and the healthy growth of the aboveground parts. Therefore, choosing a good substrate for rare plants to sow can increase the germination rate of seeds and the survival rate of seedlings, which is of great significance to the protection of rare plants. [0003] At present, plant sowing substrates mainly include imported peat, perlite, vermiculite, rice husk, sawdust, garden soil, sand, etc. and their mixtures. These matrices have d...
