Problems solved by technology

[0003] Watermelons and melons require a large amount of fertilizer, and the current soil for watermelons and melons tends to have insufficient nutrients, which will directly lead to insufficient nutrient supply and dead seedlings, and increase production costs
At present, the problem of incomplete nutrition is generally solved by applying inorganic fertilizers. However, with the increasing use of inorganic fertilizers, these fertilizers will cause soil compaction and soil fertility to decline, resulting in insufficient nutrients for watermelons and melons. Yield declines, quality deteriorates
In this case, people pay more and more attention to the research of organic fertilizers for watermelons or melons, but organic fertilizers also have the problems of poor fertilizer preservation effect and easy loss of nutrients, which need to be solved urgently

Abstract

The invention discloses an organic-inorganic composite base fertilizer for watermelons or muskmelons. The fertilizer is spherical particles, and the spherical structure comprises an inner core, a slowrelease layer coated outside the inner core, and a protective layer coated outside the slow release layer. The invention discloses a preparation method of the organic-inorganic composite base fertilizer for the watermelons or the muskmelons. The preparation method comprises the following steps: uniformly mixing the nitrogen-phosphorus-potassium composite inorganic fertilizer, humic acid and an auxiliary agent to obtain a core material; uniformly mixing urea resin, diethanolamide and water, adjusting the temperature, adding inorganic mineral powder and corn starch in a stirring state, and stirring until the viscosity of the system is not increased any more to obtain a protective material; feeding the core material into a spherical mold, and pressing to obtain an inner core; uniformly coating the surface of the inner core with a slow-release material, and then performing compression molding; uniformly coating the surface of the slow-release layer with a protective material, and then carrying out compression molding and screening to obtain the organic-inorganic composite base fertilizer for the watermelons or the muskmelons. The invention discloses the application method of the organic-inorganic composite base fertilizer for the watermelons or the muskmelons.

Description

technical field [0001] The invention relates to the technical field of soil fertilizers, in particular to an organic-inorganic composite base fertilizer for watermelon or muskmelon, a preparation method and an application method thereof. Background technique [0002] Watermelons and melons have a short cultivation cycle and high economic benefits, and their yield and planting area rank among the top ten of the world's top ten fruits. With the development of modern agriculture and the improvement of people's living standards, the cultivation of watermelons and melons has changed from focusing on output to focusing on both output and quality. How to make high-yield and high-quality watermelons and melons is not only closely related to cultivation techniques, but also closely related to scientific and reasonable formula fertilizers and soil fertility. [0003] Watermelons and melons require a large amount of fertilizer. Currently, the soil for watermelons and melons tends to h...
