Description

Technical Field

[0001] The invention relates to the technical field of special water-soluble fertilizer for sweet cherries, and in particular to a special water-soluble fertilizer for sweet cherries and a preparation method and application method thereof. Background Art

[0002] Sweet cherries have a high degree of specificity and stage-by-stage changes in their nutritional requirements during their growth. Traditional general-purpose water-soluble fertilizers often fail to accurately meet their complex nutritional requirements during various key growth periods (such as pre-flowering, young fruit, hard core, expansion, color change, post-production, and autumn fattening), which can easily lead to nutritional imbalance, poor growth, reduced fruit quality, and premature aging of the tree. In addition, element antagonism is common in conventional fertilizer formulas, which seriously affects fertilizer utilization and fertilization effects.

[0003] The prior art has the following defects:

[0004] 1. The formula is not targeted enough, and there is a lack of specially formulated water-soluble fertilizers oriented towards the needs of sweet cherries in different physiological stages.

[0005] 2. The formula lacks ecosystem considerations and lacks systematic consideration of the coordination of ecological relationships among soil inorganic matter, organic matter, microorganisms and crops in natural ecosystems.

[0006] 3. The formula lacks dialectical thinking and lacks fertilizer formula design based on the relationship between soil fertility, soil pH, ecological safety, fertilizer utilization rate and sweet cherry tree vigor.

[0007] 4. Balanced fertilizer is not balanced. For example, the commonly used formulas are: 18-18-18, 20-20-20 balanced fertilizers. After considering the fertilizer absorption and utilization rate, soil pH, and the physiological needs of sweet cherry trees, the so-called balanced fertilizer is only a balance of formula elements and has nothing to do with the actual ecological balance.

[0008] 5. The formula design is too extreme. For example, the commonly used formulas: 30-10-10 and 10-30-10, two macro-element formulas, overly emphasize the role of a single factor and ignore the mutual coordination between macro, medium and trace elements. Summary of the invention

[0009] The technical problem to be solved by the new invention is that there is a lack of a special water-soluble fertilizer on the market that can systematically and accurately design a formula according to the characteristics of the growth cycle of big cherries and effectively solve the problem of element antagonism.

[0048] A method for preparing a special water-soluble fertilizer for sweet cherries comprises the following steps:

[0049] 1) Weigh the materials according to the composition and proportion of the above fertilizer barrels ABC;

[0050] 2) Mix the raw materials thoroughly for 60 to 120 minutes to ensure that the ingredients are evenly distributed;

[0051] 3) Perform quality inspection on the mixed materials, and the inspection indicators include but are not limited to the content of each element, pH value, and moisture content.

[0052] 4) The qualified materials are packed into A barrel fertilizer packaging bag, B barrel fertilizer packaging bag and C barrel fertilizer packaging bag respectively and sealed for storage.

[0053] 5) The mineral sources of potassium humate, ammonium polyphosphate, glycine, glutamic acid, glucose, etc. are packed separately. When applying water-soluble fertilizers, they are dissolved in water in the first step and then other factors are added and dissolved.

[0054] A method for applying a special water-soluble fertilizer for sweet cherries comprises the following steps:

[0055] S1. According to the growth stage of sweet cherries, determine the water-soluble fertilizer formula corresponding to the fertilizer ABC bucket at the corresponding stage;

[0056] S2. Pour the contents of the A barrel fertilizer bag, the B barrel fertilizer bag and the C barrel fertilizer bag into the fertilizer barrels A, B barrel fertilizer and C barrel fertilizers respectively to dissolve. In the fertilizer barrel A, first dissolve the mineral potassium humate and then pour in the other elements. In the fertilizer barrel B, first dissolve the ammonium polyphosphate and then pour in the other elements. In the fertilizer barrel C, first dissolve the glycine, glutamic acid and glucose and then pour in the other elements.

[0057] S3. After dissolution, drip irrigation is carried out in the order of fertilizer barrel A, fertilizer barrel B, and fertilizer barrel C. The drip irrigation time is controlled within 90 minutes, and the drip irrigation speed is 100 liters / hour to ensure that the fertilizer is evenly applied to the soil. The application amount is determined according to factors such as the age of the sweet cherry tree, tree vigor, and soil fertility. The amount of fertilizer applied per plant each time is 100 to 300 grams.

[0058] The advantages of the present invention compared with the prior art are:

[0059] 1. Accurate nutrient supply: The ABC water-soluble fertilizer of the present invention accurately adjusts the ratio of macroelements, trace elements and functional ingredients in each growth stage according to the characteristics of the sweet cherry growth cycle, which can accurately meet the nutritional needs of sweet cherries in different growth periods, promote the healthy growth of sweet cherries, and improve fruit yield and quality. For example, increasing the phosphorus content in the pre-flowering period promotes flower bud differentiation, increasing the potassium content in the expansion period helps fruit expansion, and adjusting the nitrogen-potassium ratio in the color change period to promote sugar accumulation and color transformation.

[0060] 2. Solve element antagonism: Through the unique method of chelating metal ions with humic acid in fertilizer barrel A and storing the three fertilizer barrels ABC separately and drip fertilizing in sequence, the antagonism between elements is effectively avoided, the effectiveness and stability of various nutrients in the fertilizer are improved, and sweet cherries can fully absorb and utilize the nutrients in the fertilizer, reducing fertilizer waste and reducing fertilization costs.

[0061] 3. Improve the soil environment: Functional ingredients such as mineral potassium humate in the fertilizer can improve the soil structure, increase the soil's ability to retain water and fertilizer, promote soil microbial activity, improve soil aeration and water permeability, create a good soil environment for the growth of sweet cherry roots, and facilitate the root system's absorption of nutrients and water, thereby improving the resistance and adaptability of sweet cherries.

[0062] 4. Flexible tree vigor regulation: The design is based on the moderate tree vigor of sweet cherry. For vigorous trees, the growth control effect can be achieved by appropriately reducing the nitrogen content. For weak trees or in the case of poor soil fertility, the nitrogen content can be conveniently increased to boost the tree vigor. It can effectively adapt to the fertilization needs of sweet cherry under different tree vigor and soil fertility conditions, and improve the applicability and versatility of the fertilizer.

[0063] 5. Improve fruit quality: Reasonable ratio of nutrients and synergistic effect of functional ingredients can help improve the hardness, sweetness, color, taste and other quality indicators of sweet cherry fruit, reduce the occurrence of physiological diseases such as cracked fruit and deformed fruit, and improve the commodity value and market competitiveness of sweet cherry.

[0064] 6. Regulate soil pH value: The application of ammonium polyphosphate in the formula, its hydrolysis products can form a buffer system. When the solution enters the acidic soil, the polyphosphate ions can combine with hydrogen ions to increase the pH value of the soil solution; when entering the alkaline soil, the ammonium ions can react with the hydroxide ions to reduce the pH value of the soil solution, so that the pH value of the soil solution remains relatively stable within a certain range, plays a buffering role, and achieves the regulation of soil pH value.

[0065] 7. Outstanding functionality: The application of functional ingredients such as glycine, glutamic acid, phenylalanine, arginine, and glucose highlights their role in each growth cycle of sweet cherries, such as the application of glycine before flowering. 1. Improve stress resistance: It can enhance the adaptability of big cherry trees to adverse conditions such as drought, high temperature, and low temperature, and reduce the damage to the tree body caused by adversity. 2. Promote root development: It stimulates the division and growth of root cells of sweet cherry trees, making the root system more developed and enhancing the root system's ability to absorb water and nutrients, which is extremely beneficial to the growth of sweet cherries in early spring.
