Abstract

The invention relates to an organic fertilizer by fermented duckweed, which comprises the following raw materials by weight: 20-22 parts of green duckweed, 0.2-0.4 parts of EM bio fungus, 18-20 parts of pond mud, 15-18 parts of quicklime, 1-3 parts of copper sulphate, 4-6 parts of borax, 2.5-4 parts of ammonium molybdate, 1-2 parts of potassium chloride, 0.2-0.6 parts of ammonium molybdate, 0.6-0.8 parts of acetylsalicylic acid, 0.5-0.8 parts of magnesium sulfate, 1-2 parts of potassium dihydrogen phosphate, 0.5-0.6 parts of auxiliary agent and a proper amount of water. The organic fertilizer takes duckweed, pond mud and quicklime as main materials, the bio fungus is added for fermenting, the inorganic nutriment is added, and then steps of drying and granulation are finally carried out, the duckweed and mud are selected as the raw materials due to wide source, the refuse can be utilized, duckweed has abundant nutrition in pond, and can absorb various nutrition elements in river, and the duckweed grows vigorously and has the water purification efficacy. According to the invention, duckweed is reused and then fermented to prepare the organic fertilizer, the organic fertilizer is used in the field to realize the cycle usage of the nutrition element, so that environment can be beautified, and damage of usage of the chemical materials to the environment and crop can be reduced.

Description

A kind of duckweed fermented organic fertilizer and preparation method thereof

Technical field

The present invention is a kind of duckweed fermented organic fertilizer and preparation method thereof, belongs to the technology field of fertilizer in fertilizer.

Background technology

Organic fertilizer is rich in organic substance and the required nutritive substance of plant growth, can not only provide plant growth required nutrient, improvement soil, can also improve crop quality, improve crop yield, promote high crop yield stable yields, preservation of fertility, can improve utilization rate of fertilizer simultaneously, reduces production costs.Fully rationally utilize organic fertilizer can increase crop yield, culture fertility, improve quality of agricultural product, improve the validity of soil nutrient.Therefore; in China, apply organic fertilizer; meet the requirement of " Accelerating The Construction resource-conserving and environment-friendly society "; to promoting the friendly development of agricultural and resource, Agriculture and Environment and harmony between man and nature; from source, promote agricultural product security, cleaner production, preserve the ecological environment all significant.Along with the raising of living standards of the people, the free of contamination demand organic, green food of safety of residents health constantly increases, and vast farmers improves the market competitiveness of agricultural-food in the urgent need to application of organic fertilizers.

Country attaches great importance to the production of fertilizer, favours to support in recent years its development aspect policy.Since on June 1st, 2008, according to the documentation requirements of the Ministry of Finance and the State Tax Administration, biological organic fertilizer product was completely tax-free.Shandong Province government also subsidizes for fertilizer project for successive years.Moreover, country also starts relevant plans and the policies such as " pollution-free food action plan ", " green food ", " Organic food " authentication in succession, and agricultural-food are carried out to quality and safety control, has also driven to a certain extent the market requirement of fertilizer.Between 10 years of 2000-2010, Organic Fertilizer in China is sold average annual growth rate and is reached 56.72%, and sales revenue, by 3.55 hundred million yuan of 317.63 hundred million yuan of rising to 2010 of 2000, has increased nearly 100 times.

At present, western countries' organic fertilizer consumptions such as the U.S. have accounted for 50% of total amount, and China's Organic fertilizer industry commercialization is produced and begun to take shape, and using on a large scale of farmland is not yet universal, and accounting is less than 10%.But this has exactly also indicated that fertilizer has huge development potentiality and the market space in China.Be subject to national policy guiding and fertilizer development trend, following China organic fertilizer has a high potential, and estimates that organic rate of fertilizer will account for 30% left and right of fertilizer total quantity consumed, and in coming 10 years, Chinese organic fertilizer production will be ascendant trend year after year.
