Water-soluble fertilizer containing alginate and various nutrients and preparation method of water-soluble fertilizer

Abstract

The invention relates to water-soluble fertilizer containing alginate and various nutrients and a preparation method of the water-soluble fertilizer. The water-soluble fertilizer comprises alginate, macro-elements N, P2O5 and K2O, medium elements Ca and Mg and trace elements Cu, Fe, Mn, Mo, Zn and B, wherein the weight percentage of the alginate is 3%., the total weight percentage of the macro-elements is 57%, the total weight percentage of the medium elements is 1%, and the total weight percentage of the trace elements is 0.64%. The preparation method includes: weighing the raw materials according to the weight percentage, and crushing and sieving; weighing the alginate, and evenly mixing with nitrogen fertilizer for standby; weighing the trace elements, and mixing with calcium and magnesium fertilizer for standby; weighing phosphorus fertilizer and potassium fertilizer, evenly mixing, adding the mixture, and sufficiently mixing to obtain the water-soluble fertilizer. By the water-soluble fertilizer, fruit yield can be increased by 20-30%, vegetable yield can be increased by 25-35%, and flower quality can be increased evidently.

Description

technical field [0001] The invention relates to a water-soluble fertilizer and a preparation method thereof, in particular to a preparation method of a water-soluble fertilizer containing alginic acid and various nutritional elements. Background technique [0002] Fertilizer, as the food that supplies the nutrients needed by plants, has become an important basis for the development of modern agriculture. At present, the extensive use of traditional compound fertilizers based on nitrogen, phosphorus and potassium has seriously compacted the soil, damaged the quality of crop products, and caused a lot of pollution to the environment. Although farmyard manure can overcome the above disadvantages, the accumulation and fermentation of farmyard manure is not complete, causing problems such as the spread of pathogenic microorganisms and parasites (eggs). Therefore, it is necessary to find new bio-organic fertilizers that can replace traditional compound fertilizers and have the ef...

Problems solved by technology

At present, the extensive use of traditional compound fertilizers based on nitrogen, phosphorus and potassium has caused serious compaction of the soil, destroyed the quality of crop products, and caused a lot of pollution to the environment.

Although farmyard manure can overcome the above disadvantages, the accumulation and fermentation of farmyard manure is not complete, causing problems such as the spread of pathogenic microorganisms and parasites (eggs).
