Embodiment 1

[0021] A nutritional granule with comprehensive nutrition, comprising the following components in parts by weight:

[0022] 30 parts of lightly burned magnesium, 20 parts of magnesium sulfate, 10 parts of attapulgite powder, 20 parts of humic acid powder, 5 parts of boron fertilizer, 5 parts of zinc fertilizer, 10 parts of seaweed concentrate.

[0023] The preparation method of the nutritional granules of the present invention is as follows: mix the raw materials uniformly according to the above parts by weight, granulate by pinch plate extrusion or roller extrusion, and use roller equipment to plan round after granulation. Add seaweed concentrate to form an organic film, making the particles more round and smooth.

[0024] The preparation method of seaweed concentrate is as follows: beating and crushing fresh seaweed or beating and crushing dried seaweed after soaking and swelling, ultrasonic extraction, solid-liquid separation, alkali extraction of solid seaweed again, compo...

Embodiment 2

[0027] An organic-inorganic nutrient granule, comprising the following components in parts by weight:

[0028] 20 parts of lightly burned magnesium, 10 parts of magnesium sulfate, 10 parts of attapulgite powder, 40 parts of humic acid powder, 5 parts of boron fertilizer, 5 parts of zinc fertilizer, 10 parts of seaweed concentrate.

Abstract

The invention relates to organic-inorganic combined full-nutrition granules capable of conditioning soil or being used in blended fertilizers. The organic-inorganic combined full-nutrition granules are prepared from the following components in parts by weight, 50-60 parts of one or more of caustic calcined magnesite, a magnesium monohydrate fertilizer and brucite, 10-20 parts of attapulgite powder, 10-20 parts of humic acid powder, 3-5 parts of a boric fertilizer and 3-5 parts of a zinc fertilizer. The preparation method comprises the following steps: granulating by adopting a pinch plate extrusion or double-roller extrusion mode, carrying out circle planning treatment by using roller equipment after granulation, and adding 5-10 parts of a seaweed concentrated solution with alginic acid content of 20g / L in the circle planning process to form a layer of organic film, so that the granules are relatively round and smooth. The product can be used as a filler in blended fertilizers, can supplement medium trace elements required by crop growth, and can regulate soil.

Description

technical field [0001] The invention relates to a nutrient granule which can be used for blending fertilizers and belongs to the technical field of fertilizers. Background technique [0002] Since the 1980s, chemical fertilizers have been used in large quantities. Up to now, the amount of chemical fertilizers used has reached 58 million tons (converted to pure). The use of chemical fertilizers has greatly improved the output of agricultural products, but there are problems such as excessive application of chemical fertilizers, blind application, and low utilization rate. It has caused arable land compaction, salinization and environmental pollution, which is not conducive to the sustainable development of agriculture and the improvement of the quality of agricultural products. Therefore, a series of policies have been issued at the national level to promote and ensure the improvement of agricultural quality and efficiency, deepen the reform of the agricultural supply side, a...
