Problems solved by technology

[0002] For crops that are easy to absorb nitrate nitrogen, in order to increase the yield of crops, people often use a large amount of chemical fertilizers, but chemical fertilizers are easy to lose with water, causing environmental problems such as water eutrophication and soil compaction. In addition, nitrogen can be NO 3 - , NO 2 - The nitrate and nitrite content in drinking water and vegetables in many areas has exceeded the standard, which seriously threatens human health. The greenhouse gas NO formed by nitrification and denitrification 2 will pollute the air

Abstract

The invention discloses a fertilizer containing magnesium sulfate. The fertilizer is prepared from the following raw materials in parts by weight: 5 to 8 parts of urea, 20 to 30 parts of potassium nitrate, 10 to 15 parts of potassium monohydrogenphosphate, 10 to 15 parts of monoammonium phosphate, 5 to 8 parts of diatomite, 0.1 to 0.3 part of potassium borate, 0.3 to 0.5 part of magnesium sulfate, 0.1 to 0.2 part of calcium chloride, 0.1 to 0.2 part of zinc sulfate, 0.3 to 0.5 part of sodium molybdate, 4 to 6 parts of polyvinyl alcohol, 20 to 30 parts of soybean straws, 8 to 10 parts of soya bean meal, 8 to 10 parts of manioc waste, 0.2 to 0.3 part of EM microbial inoculums and 12 to 18 parts of film coating materials. The invention also discloses a preparation method of the fertilizer containing magnesium sulfate. The fertilizer provided by the invention has the advantages that the rich and balance nutrition is provided; the growth is promoted; through adsorption and film covering, the release speed of inorganic fertilizers can be regulated, so that the requirements of crops on nutrients can be met; the loss of a great number of inorganic fertilizers and the environment pollution are avoided.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a magnesium sulfate-containing fertilizer and a preparation method thereof. Background technique [0002] For crops that are easy to absorb nitrate nitrogen, in order to increase the yield of crops, people often use a large amount of chemical fertilizers, but chemical fertilizers are easy to lose with water, causing environmental problems such as water eutrophication and soil compaction. In addition, nitrogen can be NO 3 - , NO 2 - The nitrate and nitrite content in drinking water and vegetables in many areas has exceeded the standard, which seriously threatens human health. The greenhouse gas NO formed by nitrification and denitrification 2 It will also pollute the atmosphere. Therefore need to provide a kind of new fertilizer. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a magnesium su...
