Abstract

The invention provides a special ecological compound fertilizer for rice and a preparation method thereof. The compound fertilizer is prepared from the following raw materials in parts by weight: 28-37 parts of urea, 12-24 parts of monoammonium phosphate, 17-28 parts of potassium chloride, 4-7 parts of liquid ammonia, 2-3 parts of sulfur, 5-8 parts of liquid sodium silicate, 2-3 parts of zinc sulfate, 8-10 parts of meerschaum powder and 3-5 parts of microbial flora. The meerschaum powder is used as the adhesive by utilizing the particular viscosity, thereby obtaining favorable granulation effect. The liquid sodium silicate is coated on the fertilizer granules to obtain the slow-release function. The nutrient proportioning and rich secondary and minor elements in the product are more suitable for growth needs of rice, and have the effects of promoting the effect improvement of the fertilizer, improving the soil and enhancing the crop yield and quality.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special ecological compound fertilizer for rice and a preparation method thereof. Background technique [0002] "A single flower in a crop depends entirely on fertilizer", the widespread use of chemical fertilizers in my country's agricultural production for many years has made great contributions to agricultural development, farmers' income increase and rural prosperity. However, the extensive use of chemical fertilizers for a long time has also caused excessive soil salinity, excessive concentration of harmful ions, poor structure, easy compaction, uneven fertility in the soil, decreased fertility, and restricted crop growth and development. According to data, soil pollution in my country is becoming more and more serious, and saline-alkaline soil is growing rapidly. Improving soil and protecting the ecological environment have attracted great attention from ...
