Problems solved by technology

At present, coated fertilizers mainly include resin-coated fertilizers and sulfur-coated fertilizers. The manufacturing process of these coating materials is complicated, resulting in high fertilizer production costs; It is completely consistent; more importantly, the current slow-release and moisture-conserving compound fertilizers only inhibit the release of nutrients, and have not yet achieved the two-way regulation of accelerated release and slow release.

Embodiment 1

[0039] The composition of embodiment 1 slow-release moisture conservation microorganism ferment organic compound fertilizer:

[0040] According to specific ratio, be mixed with slow-release moisture-retaining microbial ferment organic compound fertilizer composition, concrete composition is shown in Table 1,

[0041] Table 1 Various slow-release and moisture-retaining microbial ferment organic compound fertilizer composition ingredients

[0042]

[0043]

[0044] Note:

[0045] 1) The ratio of organic compound fertilizer and inorganic compound fertilizer is by weight percentage;

[0046] 2) Various effective nutrients of special-purpose coated inorganic fertilizers in compositions 1, 2, and 3 are as follows: 3.0% nitrogen, 3.0% phosphorus pentoxide, 3.0% potassium oxide, 1.0% silicon dioxide, and a total effective nutrient of 10.0%. ;

[0047] 3) Various effective nutrients of special-purpose coated inorganic fertilizers in compositions 4, 5, and 6 are as follows: 14....

Embodiment 2

[0050] Embodiment 2 slow-release method for preparing organic compound fertilizer with moisture-preserving microorganism ferment:

[0051] Using one-time molding process, the composition in Table 1 is prepared according to the proportion of the components, and the compound fertilizer is first prepared, then the slow-release moisture retention agent is added, and then the microbial enzyme is added, poured into the mixer and mixed evenly, granulated, and dried to form a slow-moving fertilizer. Organic compound fertilizer that releases moisture-preserving microbial enzymes. Packing, inspection, storage.

[0052] 2.1 In composition 1, take by weighing 60 kilograms of beer filter sludge, add 30.0 kilograms of inorganic compound fertilizers and mix to form 90.0 kilograms of compound fertilizers, add 9.9 kilograms of konjac powder, and then add 0.1 kilograms of nitrogen-fixing bacteria, phosphorus bacteria, potassium The crop probiotics composed of bacteria and photosynthetic bacter...

Embodiment 3

[0063] Embodiment 3, the application of slow-release organic compound fertilizer of moisture-preserving microbial ferment:

[0064] 3.1 Determination of water retention capacity of slow-release moisture retention agent:

[0065] Water retention was determined by centrifugation, and as shown in the table, konjac flour, konjac flour + xanthan gum (1:1), starch_AASO were accurately weighed respectively. 3 H weight, fully dissolved with quantitative pure water respectively, filter the core, discard the water, weigh the colloid, and calculate the saturated water retention of the colloid, unit: milliliter; use yellow sand as a reference. The results are shown in Table 2.

[0066] Table 2. Water retention capacity of slow-release moisture retention agent (saturated water retention capacity of yellow sand: ml / kg)

[0067]

[0068]

[0069] As can be seen from Table 2. The saturated water-holding capacity yellow sand of the slow-release moisture-retaining agent is 300 millilite...

Abstract

The invention provides a composite of a slow-release soil moisture preserving microbial enzymes organic compound fertilizer and also provides a method for preparing the compound fertilizer of the composite and application of the slow-release soil moisture preserving microbial enzymes organic compound fertilizer in agricultural production. The slow-release soil moisture preserving microbial enzymes organic compound fertilizer provided by the invention has the advantages of bidirectional regulation on promoted release and slow release and double virtues of moisture preservation and fertility preservation, particularly has low cost, and can be widely used for the agricultural production, in particular to the agricultural production in arid regions.

Description

technical field [0001] The present invention relates to an agricultural fertilizer, in particular to a slow-release and moisture-conserving organic compound fertilizer, a method for preparing the compound fertilizer, and the application of the slow-release and moisture-conserving organic compound fertilizer in agricultural production. Background technique [0002] China is a large agricultural country, and it is also a country with the largest arid and semi-arid area. Therefore, drought resistance and moisture conservation are an important link in agricultural production. Moisture retention agents currently used in agricultural production have certain water retention and drought resistance properties, and have achieved results in solving crop water shortages and desertification control (Qin Xuejiang, Chen Shancai, Chen Jiangfeng, cassava starch synthesis of desert vegetation moisture retention agent SA-36 and its application, chemical technology and Development 2003 Issue 03...
