Example Embodiment

[0101] Preparation of sample extract: take 10g of compost test sample from 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.

[0102] Cultivate cabbage seeds: Spread a layer of filter paper on a clean petri dish, the size of the filter paper matches the size of the dish. Inject 5 mL of sample extract into the dish to make the filter paper fully wet. Then place 10 cabbage seeds with intact grains evenly on the filter paper, put them in an incubator at 25°C for 3 days, and then take them out for testing. Distilled water was used instead of the sample extract as the control group.

[0103] Determination of seed germination index: use a ruler to measure and record the root length and stem length of the seed after germination, and record the number of seeds that did not germinate. Calculation formula: Seed Germination Index GI (Germination Index)=(germination rate of ...

Abstract

The invention discloses an environment-friendly fertilizer for lotus and a preparation method thereof. The environment-friendly lotus fertilizer is prepared from the following raw materials in parts by weight: 70-80 parts of organic fertilizer, 15-25 parts of inorganic fertilizer, 1-5 parts of microelement, 0.1-0.3 part of fermenting compound bacteria, 1-2 parts of enzyme microorganism, 2-7 parts of humic acid and 0.5-1 part of chitosan oligosaccharide. The preparation method comprises the following steps: evenly mixing the fermenting compound bacteria with water in the weight ratio of 1 to (5-50) to obtain a diluted bacterial liquid; adding the diluted bacterial liquid to the organic fertilizer, mixing evenly, piling, and turning over circularly to obtain a primary fermentation product; next, adding the enzyme microorganism for fermenting until thorough decomposition, drying at a low temperature and crushing to obtain a secondary fermentation product; finally, adding such components as inorganic fertilizer, microelement, humic acid, chitosan oligosaccharide and biological bacteria, mixing evenly, pelletizing and sorting to obtain the environment-friendly fertilizer for lotus. The environment-friendly fertilizer for lotus is prepared from husbandry waste materials as the major raw materials, so that the problem of nutrient supply to lotus and the heavy metal and organic matter pollution problem in the production process of lotus can be solved.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a lotus root environment-friendly fertilizer and a preparation method thereof. Background technique [0002] At present, food safety accidents occur frequently. Farmers may also have toxic and harmful substances on the polluted land according to conventional planting methods. For example, a large number of lotus roots have recently been detected to be toxic and harmful and their metals exceed the standard, and the heavy metals in the soil exceed the standard. is its 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. ...
