Abstract

The invention discloses a fertilizer specially used for planting watermelons and relates to the technical field of planting watermelons. The fertilizer is composed of, by weight, 20-30 parts of animal excrement, 15-20 parts of plant ash, 10-15 parts of urea, 10-30 parts of soybean meal, 2-5 parts of a microbial fermented inoculant, 2-5 parts of potassium nitrate, 10-20 parts of straw, 2-5 parts of magnesium oxide, 2-10 parts of ferrous sulfate, and 3-5 parts of calcium superphosphate. A preparation method includes the steps of: adding the animal excrement, the plant ash, the soybean meal and the straw into a fermentation device, adding water to mix the components, adding the microbial fermented inoculants to carry out fermentation, separating a fermentation liquid, adding the urea, potassium nitrate, magnesium oxide, ferrous sulfate and calcium superphosphate, mixing the components uniformly, and drying and crushing the mixture. The fertilizer can modify soil and retain fertilizer and water, has high utilization rate and more comprehensive nutrients, is more durable in effects, can promote growth of the watermelons and greatly increase the yield of the watermelons, and improves the quality of the watermelons.

Problems solved by technology

At present, watermelons are planted with chemical fertilizers for a long time. The watermelons absorb less nutrients from the fertilizers, the utilization rate of fertilizers is low, and the yield is too low. Moreover, the quality of the soil environment deteriorates, a large amount of minerals in the soil are lost, and the water quality in some areas becomes eutrophic. , at the same time, the taste of the watermelon planted is not very good
