Description

Technical Field

[0001] The present invention relates to the technical field of agricultural fertilizers, and in particular to a green crop foliar fertilizer based on natural ingredients, and a preparation method and application thereof. Background Art

[0002] Foliar fertilizers, which provide nutrients to crops through foliar absorption, are widely used in modern agricultural production due to their rapid absorption, high utilization rate, and immediate effects. However, many foliar fertilizers currently available on the market often contain added chemicals and hormones in pursuit of rapid results and high yields. These substances not only pollute the soil and environment but also remain in agricultural products, impacting their quality and safety as well as human health.

[0003] With improved living standards and growing health awareness, the demand for green, organic agricultural products is growing. The production of green agricultural products requires matching green fertilizers, but existing foliar fertilizers are unable to meet this demand, causing environmental pollution and affecting agricultural product quality. Therefore, the development of a zero-pollution, hormone-free, and chemical-free green foliar fertilizer is of great significance for promoting sustainable agricultural development and ensuring agricultural product safety. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of existing foliar fertilizers, such as the presence of chemical ingredients and hormones, which can easily cause environmental pollution and secondary contamination of agricultural products. It provides a green foliar fertilizer for crops based on natural ingredients. This foliar fertilizer is zero-pollution, hormone-free, and chemical-free. It can improve crop photosynthesis efficiency, improve crop appearance and quality, significantly increase yield, and is suitable for a variety of crops. The present invention also provides a preparation method and application of this foliar fertilizer.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A green crop foliar fertilizer based on natural ingredients is composed of the following raw materials in parts by weight: 60-80 parts of water, 10-20 parts of fish scales, 5-15 parts of eggshells, 3-8 parts of brown sugar, and 2-5 parts of vinegar.

[0007] Furthermore, the foliar fertilizer is composed of the following raw materials in parts by weight: 70 parts of water, 15 parts of fish scales, 10 parts of eggshells, 5 parts of brown sugar, and 3 parts of vinegar.

[0008] The present invention also provides a method for preparing the foliar fertilizer, comprising the following steps:

[0009] (1) Clean the fish scales and crush them into fish scale powder with a particle size of 0.1-0.5 mm;

[0055] Experimental Design:

[0056] There are 8 treatment groups for each crop, namely:

[0057] Treatment group 1: spraying the foliar fertilizer prepared in Example 1;

[0058] Treatment group 2: spraying the foliar fertilizer prepared in Example 2;

[0059] Treatment group 3: spraying the foliar fertilizer prepared in Example 3;

[0061] Treatment group 5: spraying the foliar fertilizer prepared in Comparative Example 2;

[0062] Treatment group 6: spraying the foliar fertilizer prepared in Comparative Example 3;

[0063] Treatment group 7: spraying the foliar fertilizer prepared in Comparative Example 4;

[0064] Treatment group 8: sprayed with the commercially available conventional chemical foliar fertilizer of Comparative Example 5;

[0065] Control group: spray the same amount of water.

[0066] Each treatment group was replicated three times, with a plot area of ​​20 m². The foliar fertilizer was sprayed at a concentration of 500 times liquid, during the critical growth period of crops. Green beans were sprayed three times, peaches were sprayed four times, and leafy vegetables were sprayed twice.

[0068] The yield, appearance quality (commercial quality of green beans, fruit color and cleanliness of peaches, leaf thickness of leafy vegetables), growth rate (leafy vegetables), sugar content (peaches) and other indicators of crops in each treatment group were measured.

[0069] The test results are shown in Table 1-3 below:

[0075] Note: Fruit surface color: Level 1 is the reddest and Level 3 is the worst; Fruit surface cleanliness: Level 1 is the cleanest and Level 3 is the worst.

[0078] As shown in Tables 1-3, the foliar fertilizers prepared in Examples 1-3 of the present invention were significantly more effective on green beans, peaches, and leafy vegetables than the comparative examples and the control group. Treatment Group 2 (Example 2) achieved the best results, achieving a marketability level of 1 on green beans, extending the picking time by 8 days, and increasing yield by 43.1%. In peaches, the average single fruit weight reached 192g, with both fruit color and cleanliness reaching level 1, a sugar content of 14.0%, and a yield increase of 33.2%. In leafy vegetables, the leaf thickness reached 3.0mm, the growth cycle was shortened to 19 days, and the yield increased by 60.0%.

[0079] Comparative Examples 1-7, due to lacking some of the raw materials of the present invention or using commercially available conventional chemical foliar fertilizers, were not as effective as the examples of the present invention, demonstrating that the various raw materials of the present invention work synergistically and that none of them can be omitted. The control group, sprayed with plain water, achieved the worst results. Furthermore, while the commercially available conventional chemical foliar fertilizer in Treatment Group 8 showed some effectiveness, it fell short of the examples of the present invention in terms of appearance, quality, safety, and potential secondary contamination. Testing of the agricultural products from each treatment group revealed that the agricultural products from the treatment groups of Examples 1-3 of the present invention were free of detectable hormones and harmful chemical components, meeting green agricultural product standards. However, the agricultural products from the treatment group of Comparative Example 5 showed traces of hormone residues.
