Functional fertilizer additive, special formula fertilizer for watermelon and preparation method thereof

Abstract

The invention discloses a fertilizer functional additive, a muskmelon special-use formula fertilizer and a preparation method thereof. The muskmelon special-use formula fertilizer is prepared from following components, in a blending manner, diammonium phosphate granules, ammonium nitrate phosphorus granules, potassium nitrate granules, potassium sulfate granules, magnesium sulfate monohydrate granules, zinc sulfate monohydrate granules and the fertilizer functional additive granule. The fertilizer functional additive granule is prepared from following components, in a compounding, mixing and granulating manner, EDTA calcium, EDTA iron, EDTA manganese, disodium octaborate tetrahydrate, sodium molybdate, anionic polyacrylamide, citric acid and poly amino polypeptide. The muskmelon special-use formula fertilizer has the excellent effects of regulating soil, activating nutrients, scientifically supplying nutrients, enhancing resistance and increasing yield and quality. The preparation method is simple, is low in consumption, and has a popularizing and applying value. The muskmelon special-use formula fertilizer has a high fertilizer efficiency, is reduced in use amount, can improve soil and increase fertilizer utilization rate, can increase the yield and improve the quality of muskmelons, can reduce production cost and is especially suitable for the tendency of zero-increase of chemical fertilizer use amount in modern agriculture.

Description

technical field [0001] The invention belongs to the technical field of new fertilizers, and in particular relates to a functional additive for fertilizers, a special formula fertilizer for watermelon and a preparation method thereof. Background technique [0002] Melon is a traditional summer fruit with a short cultivation cycle and high economic benefits. Its yield and planting area rank fifth among the top ten fruits in the world. With the development of modern agriculture and the improvement of people's living standards, the cultivation of melons has changed from focusing on output to focusing on both output and quality. How to make watermelon high-yield and high-quality is not only closely related to cultivation technology, but also closely related to scientific and reasonable formula fertilizer and soil fertility. [0003] Watermelon needs a lot of fertilizer and likes nitrate nitrogen. If the content of ammonium nitrogen fertilizer is too high, it will cause ammonium ...

AI Technical Summary

Problems solved by technology

However, phosphate fertilizer is easy to form hydroxyapatite with calcium and magnesium ions in calcareous soil, and it is easy to form precipitation or closed storage state phosphorus with iron and aluminum ions in acidic soil, which greatly reduces the effectiveness of phosphate fertilizer; calcium, magnesium, iron, manganese , zinc and other medium and trace elements also have problems such as easy fixation and low nutrient availability

At present, in the process of planting melons, there are problems such as unreasonable fertilization, soil compaction, decline in soil fertility, increase in pests and diseases, and decline in the yield and quality of melons.
