Special potato polymerization fertilizer and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizers, and relates to a potato polymerization special fertilizer and a preparation method thereof, the special fertilizer is prepared by mixing, heating polymerization, drying and crushing raw materials comprising a water-absorbent polymer monomer, inorganic nutrients, a catalyst, a cross-linking agent and an initiator; the inorganic nutrients comprise nitrogen fertilizer, phosphate, potassium salt, silicate, calcium salt, magnesium salt, ferric salt, borate, copper salt, molybdate, manganese salt and zinc salt; the potatoes planted by using the special polymerized fertilizer are rich in mineral substances, amino acids and trace elements, the balanced uptake of nutrient elements by a human body is met, the nutrition and health of the human body are ensured, and the special polymerized fertilizer is simple in preparation method, low in production cost, labor-saving, time-saving, energy-saving, environment-friendly, non-toxic, harmless, residue-free, completely degradable, non-volatile, non-explosive, non-combustible, insoluble in water and suitable for popularization and application. Long-term effectiveness is realized; the quality is safe and reliable; and the market prospect is wide.

Description

Technical field: [0001] The invention belongs to the technical field of special fertilizer for plants and its preparation, and relates to a special fertilizer for potato polymerization and a preparation method thereof. Background technique: [0002] Potatoes, also known as ground beans, potatoes, yams, etc., are annual herbaceous plants of the family Solanaceae and are the fourth major food crop in the world, second only to rice, wheat and corn. Potato has many advantages such as wide adaptability, high and stable yield, and comprehensive nutrition. It is known as the "second bread" of human beings. However, in recent years, with the excessive application of chemical fertilizers and pesticides, it has brought great pollution hazards to soil, water sources, and the atmosphere, and the yield and quality of potatoes have declined significantly. [0003] At present, in the current situation of potato fertilizers, organic fertilizers, chemical fertilizers, and biological bacteri...

AI Technical Summary

Problems solved by technology

[0004] Traditional fertilizers have some disadvantages. The disadvantages of chemical fertilizers are: the nutrient is relatively single, and several fertilizers are usually required to be applied together; the nutrient release speed is fast, and the vertical balance supply capacity is poor; The rate is not high; acid, alkali, and salinity are strong, and improper application is not only unfavorable to plant growth, but may also deteriorate the soil and reduce soil fertility; the disadvantages of organic fertilizers are: low nutrient content, slow fertilizer efficiency, and when the nutrients in the fertilizer Low seasonal utilization rate, high temperature burning seedlings, release of ammonia and other disadvantages, due to the large amount of fertilization, it consumes more transportation and application labor. During the period when crops grow vigorously and require more fertilizer, organic fertilizers cannot meet the crop's demand for nutrients in time; Another disadvantage of fertilizer is that it is easy to cause heavy metals in the soil to exceed the standard; while biological bacterial fertilizer cannot directly provide nutrients absorbed by crops (including nitrogen, phosphorus, potassium and various mineral elements), and the fertilizer effect it can provide cannot meet the requirements of crop growth for nutrients. needs

[0005] At present, the proportion of fertilizer nutrients in the market is fixed, and it is difficult to adapt to the different needs of various crops. It is often necessary to supplement and adjust with simple fertilizers, which is time-consuming and laborious; excessive application of chemical fertilizers and pesticides has brought great pollution to the soil, water sources, and the atmosphere. Hazards, the yield and quality of potatoes also decreased significantly
