Description
Technical Field
The invention belongs to the field of agricultural fertilizers, and particularly relates to a multifunctional water-soluble fertilizer and a preparation method thereof.
Background
Under the conditions of excessive planting and improper management of agricultural planting in China, serious soil problems exist. One is soil organic matter reduction. Farmyard manure is not applied or is applied for a long time, straw returning is lacked, green manure is not planted, and organic matters in soil cannot be supplemented; the excessive application of chemical nitrogen fertilizer and the high yield exceeding the soil load, the frequent top soil plowing aggravates the exhaustion of soil carbon, and leads to the reduction of the organic matter content of the soil. The reduction of organic matters in soil can cause the destruction of soil structure and soil hardening, the reduction of soil fertility, the deterioration of physical, chemical and biological properties of soil, the acidification and secondary salinization of soil, the aggravation of soil-borne diseases, the reduction of soil purification capacity and the like. Secondly, soil hardening. Due to the lack of organic matters in the farmland soil, unreasonable cultivation and irrigation, the application of a large amount of chemical fertilizers, soil acidification and secondary salinization of the soil, the soil conglomeration is damaged, and the soil is hardened. Soil hardening directly causes oxygen deficiency, water deficiency and fertilizer deficiency of a soil-plant system, and influences substance transformation and energy exchange of the soil-plant system, even certain physiological activities and life metabolism can not be normally carried out or stopped, or transformation to harmful directions is carried out. Thirdly, soil malnutrition. In the production, the fertilizer is not applied according to the proportion of nutrient elements required by crops, the fertilizer is not applied according to the soil formula, nitrogen, phosphorus and potassium are applied in a blind excess manner, organic fertilizer and medium and trace element fertilizer are not applied or are applied in a small amount, so that the enrichment of nitrogen and phosphorus in soil is caused, the depletion of medium and trace elements such as potassium, calcium, magnesium, boron, zinc, iron, molybdenum and the like in soil is caused, the proportion of nitrogen, phosphorus and potassium is disordered, the proportion of nutrients between macroelements and the medium and trace elements is disordered, the antagonism of the nutrient elements in the soil is caused, and the fertilizer is useless. And fourthly, chemical products such as pesticides and the like are polluted. The excessive use of chemical products such as pesticides and chemical fertilizers damages the ecological balance of soil, causes a large amount of beneficial organisms in the soil to die, reduces the biological population of the soil, deteriorates the physical, chemical and biological properties of the soil, reduces the activity of the soil, deteriorates the function of the soil, and causes the soil to lose the production capacity and the agricultural utilization value by serious pollutors.
Patent application CN106748490A discloses a functional fertilizer with nutrition conditioning effect for southern tomatoes, which comprises the following raw materials in percentage by weight: 20 to 45 percent of urea, 10 to 20 percent of monoammonium phosphate, 28 to 48 percent of potassium sulfate, 0 to 20 percent of ammonium sulfate, 0.1 to 1.0 percent of medium and trace element complex composition, 0.5 to 1.5 percent of nano slow-release synergist and 1 to 5 percent of micromolecular organic carbon. According to the technical scheme, according to the nutrient requirements of the tomatoes and the characteristics of soil in the south, a biological source medium-trace element complex composition, a nano slow-release synergist and organic micromolecular carbon (the content of organic matters is more than or equal to 95%) are blended on the basis of nitrogen, phosphorus and potassium fertilizers required in the growth process of the tomatoes, the growth of the tomatoes in the growth period is facilitated, the effects of slow release and loss control of nutrients are achieved, the capability of the tomatoes for coping with stress environments is enhanced, and the purposes of increasing yield and improving quality are achieved. Most of the functional fertilizers are nitrogen, phosphorus and potassium fertilizers, and a small amount of medium and trace elements, monosodium glutamate fermentation waste liquid and the like are supplemented, so that the physical and chemical properties of soil cannot be well improved.
