Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a special slow-release fertilizer for watermelons and a preparation method thereof. Background technique [0002] In watermelon production, fertilization is an important measure to ensure yield and quality. Watermelon is a potassium-loving crop. Potassium deficiency will cause slow growth of watermelon plants, fragile stems, and dry leaf margins. Especially during the expansion period of watermelons, potassium deficiency will cause fragile transport tissues, hinder nutrient synthesis and transportation, and accumulate sugar. affected. Watermelon also has special requirements for nitrogen. Insufficient supply of nitrogen fertilizer will cause slow plant growth and small leaves, which will affect fruit expansion and low yield. Excessive nitrogen will result in leggy stems and leaves, delayed flowering and fruiting, and poor disease resistance. In addition, too mu...

Problems solved by technology

These fertilizers are generally expensive, and lack the characteristics of increasing soil fertility and improving soil structure.

[0004] On the other hand, at present, my country has become one of the countries with the largest amount of waste production in the world. According to reports, the total annual production of various crop straws in my country has reached more than 700 million tons, while organic waste (such as sugar factory production wastewater, Winery production wastewater, paper mill production wastewater or sludge, etc.) have a larger annual production volume, and these wastes are often not treated well, which not only wastes a lot of precious resources in vain, but also brings serious pollution to the environment
