preparation example Construction

[0183] Preparation of sample leaching solution: Take 10g of compost test samples in a 150mL Erlenmeyer flask, add 90mL of distilled water, add about 10-20 glass beads, shake on a shaker at 120r / min for 30min, settle for 30min, and take the supernatant.

[0184] Cultivate cabbage seeds: Spread a layer of filter paper in a clean Petri dish, the size of the filter paper matches the size of the dish. Inject 5mL of sample extract into the plate to fully wet the filter paper. Then place 10 whole grains of Chinese cabbage seeds evenly on the filter paper, put them into a 25°C incubator for 3 days, and then take them out for detection. Distilled water was used instead of sample extract as a control group.

[0185] Determination of seed germination index: Use a straightedge to measure and record the root length and stem length of the seeds after germination, and record the number of seeds that have not germinated. Calculation formula: seed germination index GI (Germination Index) = (...

Abstract

The invention discloses compound microorganism environment-friendly fertilizer and a preparation method thereof. The compound microorganism environment-friendly fertilizer is prepared from the following raw materials in parts by weight: 60-70 parts of organic fertilizer, 20-25 parts of inorganic fertilizer, 1-5 parts of microelement, 0.1-0.5 part of fermentation compound bacteria, 1-2 parts of enzyme microorganism, 2-5 parts of humic acid, 0.1-0.5 part of chitosan oligosaccharide and 1-2 parts of biological bacteria. The preparation method of the compound microorganism environment-friendly fertilizer comprises the following steps: uniformly mixing fermentation compound bacteria with water, so that a diluted bacterium solution is obtained; adding the diluted bacterium solution into organic fertilizer, uniformly mixing, piling up to form piles, and circularly rolling over, so that primary fermentation broth is obtained; then adding enzyme microorganism, fermenting until thorough decomposition is realized, drying at low temperature, and smashing to obtain secondary fermentation broth; and finally adding inorganic fertilizer, microelement, humic acid, chitosan oligosaccharide and biological bacteria, and sorting, so that the compound microorganism environment-friendly fertilizer is obtained. The compound microorganism environment-friendly fertilizer is prepared by taking waste in the agriculture and animal husbandry as a main raw material, so that the problem of crop nutrient supply and the problem of heavy metal and organic pollution in an agricultural product production process are solved.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a compound microbial environment-friendly fertilizer and a preparation method thereof. Background technique [0002] At present, food safety accidents occur frequently. Farmers may also experience excessive heavy metals in the polluted land according to conventional planting methods. For example, a large number of heavy metals in Hunan rice have exceeded the standard recently, and the excessive heavy metals in the soil is the main cause. In addition, due to the long-term use of pesticides and chemical fertilizers, the content of artificial organic pollutants in the soil is getting higher and higher, and the phenomenon of agricultural environmental pollution and ecological imbalance in my country is becoming more and more serious. The yield and quality of crops are seriously affected, which in turn threatens the survival of human beings. The environment, the resulting pollution o...
