Special compound fertilizer for watermelons and preparation method of special compound fertilizer

Abstract

The invention discloses a special compound fertilizer for watermelons and a preparation method of the special compound fertilizer. The special compound fertilizer for watermelons comprises the following substances in parts by weight: 10-26 parts of high-quality candy pomace, 2-4 parts of fulvic acid, 1-4 parts of adhesive, 10-28 parts of urea, 8-20 parts of monoammonium phosphate, 2-15 parts of potassium sulfate, 20-30 parts of ammonium sulfate, 1-4 parts of trace elements, 2-5 parts of charcoal and 3-5 parts of traditional Chinese medicine. The preparation method comprises the following steps: grinding the previous substances, uniformly mixing, and granulating, thereby obtaining the special compound fertilizer for watermelons. The special compound fertilizer for watermelons disclosed by the invention has the quick effect of an inorganic fertilizer and also has the long-acting and slow-release effects of an organic fertilizer, the volume weight of the soil is reduced, the granular structure in the soil is increased, the pH value of the soil is regulated, the special compound fertilizer has the effects of effectively expelling insects and sterilizing, the sugar content of the watermelon fruits is improved, and the solid content is increased, so that the yield and quality of the watermelons are improved. Meanwhile, the orchard soil can be improved, the environment is protected, and the special compound fertilizer has wide application prospects in green fruit production.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special compound fertilizer for watermelons and a preparation method thereof. Background technique [0002] Compound fertilizer refers to the fertilizer made of organic materials such as livestock and poultry manure, animal and plant residues, etc., which are fermented and decomposed, and then added with inorganic fertilizers. Organic fertilizers have slow fertilizer effects and have the effect of improving soil, but they cannot meet the nutrient needs of high-yield crops. Inorganic fertilizers have fast fertilizer effects, but if they are not applied properly, they will cause problems such as soil acidification, compaction and decline in organic matter content. Organic-inorganic compound fertilizers not only have the advantages of fast fertilizer efficiency of inorganic fertilizers, but also have the advantages of improving soil with organic fertilizers.

AI Technical Summary

Problems solved by technology

However, in order to pursue high yields, many melon farmers often apply excessive amounts of chemical fertilizers. The nutrients cannot be effectively absorbed by watermelons. Nitrogen, phosphorus, and potassium are easily fixed by the soil, forming salt accumulation and causing soil acidification; some excess nitrogen and phosphorus Nutrients such as potassium and potassium flow into the water system, causing eutrophication of the water body, which has a certain impact on the environment; the soil nutrient structure is unbalanced, and the physical properties deteriorate, which can easily cause nutritional imbalance in the watermelon during the expansion period, and part of the body's transformation and synthesis are hindered, resulting in watermelon containing sugar. The amount is reduced, the taste is not good, bland and tasteless

Many people who love to eat watermelon say that the current watermelon is not good

The sales of low-quality watermelons are not smooth, and the price is also low, which directly affects the economic benefits of growers

[0004] At present, the nutrients in watermelon fertilizers are not comprehensive, which leads to the ineffective absorption and utilization of fertilizers during the growth of watermelons, resulting in malnutrition in the later stage. In addition, it is also necessary to reasonably adjust the timing of fertilization during the fertilization process, resulting in nutrient imbalance and fertilizer absorption and utilization. The rate is low, resulting in low watermelon yield

At the same time, during the growth of watermelon, it is extremely vulnerable to the invasion of diseases and insect pests. In order to reduce or eliminate the impact of diseases and insect pests on crops, various pesticides are used in the planting and growth stages of crops, which will not only bring soil, water and Air pollution, and pesticides will be absorbed by crops, resulting in pesticide residues in agricultural products, which seriously threaten human life and health
