Embodiment 1
[0035] 1. Preparation of matrix.
[0036] Straw is purchased from farmers' fields, rice husk, sawdust, biogas residue, mushroom residue and wine residue are purchased from the market, and plant capsules are purchased from the market. The manufacturer is Shanxi Guangsheng Capsule Co., Ltd.
[0037] (1) Mix straw, rice husk, sawdust, biogas residue, mushroom residue, and wine residue evenly, and the mass ratio of straw, rice husk, wood chips, biogas residue, mushroom residue, and wine residue is 40:20:15:15:15 : 15, the matrix raw material was obtained.
[0038] (2) Add fermenting agent to the substrate raw material, the mass ratio of fermenting substrate and fermenting inoculating agent is 500:1, adjust its water content to 60%-65%, compost and ferment for 30 days to obtain compost fermentation product. The fermenting agent is a mixture of saccharomyces, actinomycetes, lactic acid bacteria and bacillus; Bacillus dead valley, the mass ratio of yeast, actinomycetes, lactic acid...
Embodiment 2
[0053] Embodiment 2: arbuscular mycorrhizal seedling raising substrate cultivates robust seedlings
[0054] 1. Test method
[0055] Watermelon and tomato seeds were soaked, sterilized, and germinated. After the seeds germinated and turned white, seeds that were plump and uniformly germinated were sown in a 50-hole tray equipped with a mixed matrix, one seed per hole. After sowing, the plug trays were placed in the glass greenhouse. During the seedling raising period, according to the moist state of the seedling raising substrate and the growth state of the seedlings, the water of the substrate is replenished with tap water from time to time, and the watering amount of each plug is based on the fact that the water does not leak out of the plug.
[0056] 2. Test results
[0057] Table 3 shows that, compared with the substrate not containing arbuscular mycorrhizal bacteria, the arbuscular mycorrhizal seedling raising substrate of the present invention significantly improves the...
Embodiment 3
[0064] Embodiment 3: the advantage after the transplanting of the watermelon seedling that the arbuscular mycorrhizal seedling raising substrate of the present invention cultivates
[0065] 30 days after the transplanting of the watermelon seedlings cultivated by the seedling-raising matrix prepared in embodiment 1, the growth condition was better than the watermelon seedlings cultivated by the common seedling-raising matrix ( Figure 5 A), the watermelon seedlings after 28 days of seedling cultivation were transplanted into the potted plants filled with the above-mentioned mixed matrix, and three watermelon seedlings were transplanted in every pot. According to the wet state of the substrate and the growth state of the watermelon seedlings, supplement the moisture of the substrate with tap water from time to time, and the amount of water for each pot is based on the fact that the water does not leak out of the pot. By measuring the growth index of watermelon one month after t...
