Description

Technical Field

[0001] The present invention relates to the technical field of agriculture, and in particular to a crop growth regulation method based on functional blended fertilizers and a formula thereof. Background Art

[0002] With the development of modern agriculture, traditional fertilizer products are gradually failing to meet the comprehensive nutritional needs of crops. While nitrogen, phosphorus, and potassium (NPK) are essential nutrients for crop growth, the single nutrient supply of traditional fertilizers cannot provide sufficient support for crop resistance to lodging, pests and diseases, and drought tolerance, especially for lodging-prone crops like corn, wheat, and rice.

[0003] Furthermore, with advancements in agricultural technology, soil quality and fertilizer utilization efficiency have become pressing issues. Fertilizer nutrients are easily carried away by water or lost through evaporation during application, resulting in not only nutrient waste but also environmental pollution. Therefore, developing fertilizer products that can provide long-term nutrient delivery, increase fertilizer utilization efficiency, and improve soil quality has become a top priority.

[0004] Although there are some fertilizer products on the market that have a slow-release effect or have added some trace elements, the following problems still exist: the fertilizer ingredients are unbalanced and lack comprehensive supplementation of medium-amount elements (such as calcium, magnesium, sulfur, etc.); the fertilizer's anti-lodging function is insufficient, especially for some crops that are prone to lodging; the fertilizer utilization rate is not high, which can easily cause nutrient loss, leading to frequent fertilization and increased costs.

[0005] Therefore, the present invention aims to provide a functional fertilizer that can improve crop nutrition, enhance stress resistance, and increase fertilizer utilization rate, and can effectively prevent crops from lodging in severe weather such as wind and rain, thereby ensuring stable and high crop yields. Summary of the Invention

[0006] To achieve the above object, the present invention provides the following technical solution: a functional blended fertilizer comprising the following components in the following mass ratios:

[0007] Nitrogen (N): 24%

[0008] Phosphorus (P2O5): 10%

[0009] Potassium (K2O): 12%

[0010] Calcium (Ca): 5%

[0011] Magnesium (Mg): 10%

[0012] Sulfur (S): 10%.

[0013] Among them, the fertilizer adopts coating slow-release technology, and nutrients are gradually released within 60 to 90 days, ensuring the durability of fertilizer effect and efficient utilization of fertilizer.

[0014] Preferably, the coating slow-release technology uses polymer material coating, which can effectively extend the release cycle of the fertilizer, improve the utilization rate of the fertilizer, and reduce the loss of nutrients.

[0015] Preferably, the ratio of calcium, magnesium and sulfur is optimized to promote the development of crop roots, the robustness of stems, and significantly improve the lodging resistance of crops, and is particularly suitable for crops prone to lodging, such as corn, wheat, and rice.

[0016] Preferably, the fertilizer can improve the long-term sustainable use capacity of the soil by effectively regulating the pH value of the soil, alleviating the problem of soil compaction, and improving the water and fertilizer retention capacity of the soil.

[0017] A crop growth regulation method based on functional blended fertilizers, characterized in that the fertilizer can be applied as a base fertilizer or as a topdressing fertilizer, and when sowing, the fertilizer is kept at least 5 centimeters away from the seeds to avoid direct damage to the seeds.

[0018] Compared with the prior art, the present invention provides a crop growth regulation method based on functional blended fertilizers and its formulation, which has the following beneficial effects:

[0019] 1. The crop growth regulation method and formula based on functional blended fertilizers not only provide the basic elements (nitrogen, phosphorus, and potassium) required for crop growth, but also specifically add secondary elements such as calcium, magnesium, and sulfur. These elements have a significant effect on the root development, stem robustness, and lodging resistance of crops. Through scientific proportioning, balanced nutritional support can be provided at different growth stages of crops. The synergistic effect of calcium, magnesium, sulfur and other elements in the present invention can strengthen the structure of crop cell walls and significantly improve the toughness of crop stems, thereby enhancing the lodging resistance of crops, especially for crops prone to lodging, such as corn, rice, and wheat.

[0020] 2. This crop growth regulation method and formulation based on functional blended fertilizers utilizes coating and slow-release technology to gradually release fertilizer nutrients over 60 to 90 days, significantly reducing nutrient loss and improving fertilizer utilization. Crops continuously receive the nutrients they need throughout their growth cycle, reducing the need for frequent fertilization, saving costs, and reducing the environmental burden.

[0021] 3. The crop growth regulation method based on functional blended fertilizers and its formula, wherein the sulfur element can effectively regulate soil pH and alleviate soil compaction problems, the magnesium element promotes chlorophyll synthesis, improves crop photosynthesis and quality, and at the same time enhances the soil's water and fertilizer retention capacity, helping to improve the sustainable utilization of the soil. The fertilizer of the present invention reduces nutrient volatilization and leaching, conforms to the trend of ecological agriculture, reduces environmental pollution, and meets the requirements of modern agriculture for environmental protection and sustainable development.
