Embodiment 1

[0086] Embodiment 1, the preparation of biosynergist

[0087] 1) Material selection: choose fresh, dry, mildew-free soybean stalks, mung bean stalks, pea stalks, millet stalks, barley stalks, rapeseed stalks, peanut stalks, chili stalks, tomato stalks and medicinal residues from industrial-scale pharmaceutical factories. 100kg (on a dry basis).

[0088] 2) Adjust humidity and PH: Weigh about 3-4kg of caustic soda and dissolve it in 45kg of clean water to fully dissolve it, stir it evenly and then spray it on the material, mix it well, and there should be no wet lumps. The PH is controlled at 6 (tested with a wide range of PH1-14 test paper), and the water content is controlled at about 50% (it needs to be controlled by hand to form a ball, and it will loosen when you let go). The specific amount of alkali and water should be determined according to the wetness and PH of raw materials.

[0089] 3) Bagging: Use cloth bags or woven bags, about 10kg per bag, not too much or too ...

Embodiment 2

[0099] Embodiment 2, biological straw fertilizer semi-finished product preparation

[0100] (1) Crushing: Take soybean stalks, mung bean stalks, pea stalks, millet stalks, barley stalks, rape stalks, peanut stalks, chili stalks, tomato stalks and industrial (pharmaceutical factory) dregs, about 500Kg on a dry basis. Enter the hay cutter and cut into 3-5 cm fragments.

[0101] (2) Wetting: Wet the crushed straw with water, and the amount of water added is 70% of the wet weight of the raw material.

[0102] (3) Adjust the carbon-nitrogen ratio: add urea to the wet straw fragments to adjust the carbon-nitrogen ratio to 25:2 (weight ratio).

[0103] (4) pH adjustment: use lime to adjust pH to 6.5-8 in the above materials, and the amount of lime is about 3%.

[0104] (5) Add bacterial agents: mix biological agents (3 kg of microbial nitrogen-fixing bacteria, 3 kg of filamentous fungi, 5 kg of yeasts, and 1 kg of actinomycetes) with the materials after pH adjustment, and carry out...

Embodiment 3

[0117] Embodiment 3, the preparation of finished product of biological straw fertilizer

[0118] (1) Carry out the computer formula on the automatic computer batching machine, set the batching amount of each raw material, that is, all the biological straw fertilizer semi-finished products 500kg, urea 217.5kg, monoammonium phosphate 100Kg, potassium sulfate 100Kg and embodiment 1 obtained in embodiment 2 The obtained biosynergist takes 82.5 Kg.

[0119] (2) Raw material pretreatment: all the semi-finished biological straw fertilizer obtained in Example 2, 217.5kg of urea, 100Kg of monoammonium phosphate, and 100Kg of potassium sulfate were respectively crushed and sieved.

[0120](3) Dry powder mixing: Add the pretreated raw materials into the high-efficiency mixer in batches according to the above weight ratio for mechanical mixing.

[0121] (4) Finished product: the appearance of powdery biological straw fertilizer is off-white, and the uniform powder does not agglomerate; ...

Abstract

The invention discloses a biological straw fertilizer, and a production method and application thereof, and belongs to the field of fertilizer. The biological straw fertilizer contains the following components: nitrogen, phosphorus and potassium (N + P2O5 + K2O); straw organic matters; and biological synergist. A single nutrient content of the nitrogen, phosphorus, potassium and straw organic is not less than 1.6-2.5%; and the biological synergist is prepared by biological fermentation on soybean straw, mung bean straw, pea straw, millet straw, barley straw, rape straw, peanut straw, capsicum rod, tomato rod and drug residue from industrial scale pharmaceutical factory. The biological straw fertilizer protected by the present invention combines effects of microbial fertilizer, and organic and inorganic fertilizer, and can protect the ecological environment. From farm to table, standard safe production of grain can be executed. Therefore, the biological straw fertilizer is a non-toxic, harmless, green and environment-friendly fertilizer.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a biological straw fertilizer and its production method and application. Background technique [0002] With the development of industrialization, urbanization and agricultural industrialization, the degree of pollution of the agricultural ecological environment has become more and more serious, and the scope has become wider and wider. The deterioration of the agricultural production environment has seriously threatened the sustainable development of agricultural production. [0003] Moreover, with the continuous improvement of agricultural production levels, the dependence on chemical products such as chemical fertilizers, pesticides, herbicides, and plant growth regulators is increasing. Excessive application of chemical fertilizers, especially nitrogen fertilizers, not only leads to an imbalance of soil nutrients, but also increases production costs and pollutes the earth. Excessiv...
