Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water-soluble fertilizer production, and particularly relates to a calcium-magnesium nutrient element and biological stimulant containing quality improving and yield increasing fruit swelling fertilizer. BACKGROUND

[0002] The application technology background of calcium-magnesium medium element water-soluble fertilizer in agriculture mainly focuses on the comprehensive needs of improving crop yield and quality, coping with soil nutrient imbalance, optimizing fertilization technology and enhancing agricultural sustainability and the like. The following analyzes the core dimensions of the technical background: I. Crop demand and soil nutrient deficiency status 1. Irreplaceable physiological function of calcium and magnesium Calcium (Ca): involved in cell wall formation, enhances fruit hardness, prevents fruit cracking (such as tomato collar rot), and improves stress resistance (such as lodging resistance, storage and transportation resistance). Magnesium (Mg): as a core element of chlorophyll, directly related to photosynthetic efficiency; at the same time, it activates various enzymes and affects energy metabolism and grain filling.

[0003] 2. Soil nutrient deficiency is common and restricts productivity The effective magnesium in the rice-oil rotation area of the Yangtze River Basin is significantly deficient, resulting in annual yield loss (9.5%~23.8% reduction in oilseed rape yield, 2.2%~4.0% reduction in rice yield).

[0004] Calcium is easy to precipitate in alkaline soil, and magnesium is easy to lose in acidic soil, and the utilization rate of traditional fertilizer is low (calcium absorption rate of less than 5% in conventional fertilization).

[0005] II. Advantages and classification of water-soluble fertilizer technology 1. Technical characteristics High efficiency and precision: through leaf spraying or drip irrigation, the nutrient utilization rate is 2 times that of traditional fertilizer, and water saving is 30%~50%.

[0006] Flexible compounding: can be combined with pesticides and growth regulators (such as potassium dihydrogen phosphate and brassinolide) to realize "water, fertilizer and pesticide integration".

[0007] Product classification and standards III. Key technical difficulties and innovation direction 1. Limitations of traditional calcium and magnesium fertilizers Poor mobility: calcium is difficult to transport in the plant body, and the fruit is prone to calcium deficiency; Weak compatibility: mixed with phosphorus fertilizer, easy to precipitate (such as calcium phosphate); Environmental impact: excessive application aggravates soil salinization.

[0008] 2. Technical innovation breakthrough point: Nanotechnology: through crystal type control and surface activation, nano calcium (particle size <100 nm) can penetrate the leaf wax layer and achieve targeted enrichment (such as 30% increase in calcium content in tomato fruit).

[0009] Anti-precipitation process: Add chelating agents (EDTA, citric acid) to stabilize ions; Acid buffer (pH 5.5~6.5) to prevent alkaline precipitation.

[0010] Magnesium fertilizer precise operation: In rice-oil rotation, optimize magnesium fertilizer distribution (oilseed rape season: rice season ≈ 2:1), and when the annual use amount is 60 kgMgO / hm², yield and soil magnesium balance win-win.

[0011] Four, application scenarios and technical specifications 1. Regional formula design Yangtze River Basin Rice-Oil Rotation: Magnesium Fertilizer Base Application (Oilseed Rape Season 38.1 kg / hm²) + Rice Topdressing (22.3 kg / hm²); Facility agriculture: drip irrigation calcium magnesium fertilizer (Ca 100g / L formula: magnesium sulfate + magnesium nitrate compound), avoid chlorine ion damage to chlorine-avoiding crops.

[0012] 2. Adversity coordination management Intelligent application specification Unmanned aerial vehicle flight prevention: 1.5~3L of liquid per mu, flight height 2~3m (payload <50L), avoid high temperature period (>30℃ stop spraying); secondary dilution method: first dilute the mother liquor, prevent local concentration too high and burn seedlings.

[0013] Policy and industry-driven fertilizer reduction action: promote low-grade magnesite resources to prepare environmentally friendly magnesium fertilizer; green fertilizer research and development: such as silicon calcium potassium magnesium fertilizer (phosphogypsum + dolomite sintering), with soil cadmium (Cd) passivation effect.

[0014] Summary: The application of calcium and magnesium medium element water-soluble fertilizer technology needs to take the soil-crop system demand as the core, combined with the intelligent equipment of the regional adversity characteristics, through the nanometer modification, formula synergistic optimization and precise operation to realize the "reduction and efficiency increase". Future research and development need to further explore the interaction mechanism of calcium, magnesium and other elements (such as zinc and silicon), and integrate sensor technology to realize dynamic regulation to respond to the demand of agricultural green and high-quality development. However, the existing calcium and magnesium synergistic technology patent technology still has many shortcomings. First, the nutrient elements are not comprehensive. Many of them contain nitrogen, phosphorus, potassium and other macroelements, but pay insufficient attention to microelements. Plant growth needs the synergistic effect of multiple elements, and the lack of microelements can easily lead to physiological disorders in crops, such as zinc deficiency, which can cause leaf discoloration and growth inhibition, and boron deficiency, which can affect fruit development. Second, the specificity is not strong. Different soil types and crops have different fertilizer requirements. Some existing macroelements do not fully consider these differences. For example, some soils are acidic or alkaline, and existing macroelement fertilizers may not effectively adjust the soil pH, affecting the effectiveness of the fertilizer. For different crops, their fertilizer requirements are different, and some macroelements cannot meet the growth needs of specific crops. Third, the production process of some macroelements has defects. Hydroxyl ions are prone to reaction during storage and transportation, affecting use. Some production processes are complex and cost too high, which is not conducive to large-scale application. Fourth, some macroelement water-soluble fertilizers have limited effect on soil environment improvement. Long-term use of some macroelements may lead to soil compaction, fertility decline and other problems, and cannot effectively improve soil physical and chemical properties. In summary, the existing macroelement patent technology has many problems in the comprehensiveness of nutrient elements, specificity, production process and improvement of soil environment, and a more advanced technology of calcium, magnesium and other elements is urgently needed to meet the needs of agricultural production.
