Problems solved by technology

[0003] At present, agricultural crops generally use chemical fertilizers as fertilizers. The use of industrial chemical fertilizers has greatly increased crop yields, but it has also caused soil compaction, soil degradation, soil hardening, poor air permeability, accumulation of harmful substances, and reduction of soil organic matter nutrients. and a series of questions

Abstract

The invention discloses agricultural environmental-friendly organic fertilizer and a preparation method thereof, and belongs to the technical field of agricultural fertilizer. The organic fertilizer is prepared from the following raw materials in parts by weight: 50-80 parts of crop straw, 40-65 parts of animal waste, 3-6 parts of an EM agent, 30-40 parts of urea, 18-30 parts of potassium sulfate,15-25 parts of calcium superphosphate, 1-5 parts of humic acid and 3-8 parts of a water retention agent. The preparation method of the agricultural environmental-friendly organic fertilizer is simple, and raw materials are widely sourced, low in cost and pollution-free, so that the organic fertilizer has environmental-friendly significance; besides, fertilizer and water are retained, the fertilizer effect is lasting, soil hardening is avoided, crop growth can be promoted, and yield of crop is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an agricultural environment-friendly organic fertilizer and a preparation method thereof. Background technique [0002] Organic fertilizers have been used in agriculture for many years, especially in rural areas where a large amount of various agricultural organic wastes are randomly piled up and burned, causing environmental pollution. There are many types of agricultural organic wastes and a wide range of sources, as long as they are used reasonably Turning waste into wealth, the difference between organic fertilizers and chemical fertilizers is that organic fertilizers not only contain the three main elements of nitrogen, phosphorus and potassium, but also calcium and magnesium and other trace elements needed for crop growth. At the same time, organic fertilizers are conducive to improving soil physical properties , Improve soil fertility. [0003] At present...
