Livestock and poultry manure and crop straw can be used as raw materials for preparing fertilizers. Due to the unreasonable utilization of resources, livestock and poultry manure and crop straw have instead become sources of pollution, causing serious harm to water sources and soil
Livestock manure and crop straw are directly fermented as farmyard manure for planting and maintenance. The utilization rate is extremely low, and the fermentation of livestock manure and crop straw is not comprehensive enough to easily burn the plants

Embodiment 1
[0032] A method for preparing organic fertilizer by utilizing crop straw, specifically preparing according to the following steps:
[0033] (1) First crush the crop straw, then take 70-140 parts, carbonize it into a semi-charcoal 15-30% state, add 20-40 parts of microbial fermentation bacteria, 10-20 parts of brown sugar water or bean cake to it Fermentation is beneficial to straw sterilization and rapid fermentation to increase the utilization of charcoal;
[0034] (2) then collect 70-140 parts of poultry excrement, add 20-40 parts of microbial fermentation bacteria and 10-20 parts of soybean meal to it and ferment;
[0035] (3) After the crop straw in the above step (1) and the poultry manure in the above step (2) are respectively completely carbonized, take 15-20 parts of the fully carbonized crop straw and 60-70 parts of the fully carbonized poultry manure. Parts, mix and stir the two to make the base material;
[0036] (4) Then add 6-10 parts of carbon raw materials, 10...
Embodiment 2
[0049] In order to maximize the utilization effect of crop straw and poultry manure, in addition to using it as a base material for organic fertilizer granulation, it can also be used directly for compost fermentation.
[0050]The specific process of its preparation includes the following steps:
[0051] (1) Material ratio: about 3-4 tons of fresh manure plus 1 kg of fertilizer starter, the starter needs to be mixed with rice bran (or bran, corn flour and other substitutes) in a ratio of 1:5, and then evenly sprinkled Into the fresh manure heap, mix well;
[0052] (2) Building a pile of materials: Make a pile with the uniformly mixed bottom material in the above step (1). When making a pile, it cannot be made too small or too short, too small will affect the fermentation, and the height should be 1.5 meters to 2 meters. , with a width of 2 meters and a length of more than 2 to 4 meters, the fermentation effect is better;
[0053] (3) Turning and ventilation: proper oxygen su...

Abstract
The invention discloses a method for preparing an organic fertilizer from crop straws, which comprises the following steps: crushing the crop straws, taking 70-140 parts of the crushed crop straws, carbonizing the crushed crop straws into 15-30% of semi-carbon, and adding 20-40 parts of microbial zymophyte and 10-20 parts of brown sugar water or bean cakes into the semi-carbon for fermentation; then taking 70-140 parts of poultry manure, adding 20-40 parts of microbial zymophyte and 10-20 parts of bean flour into the poultry manure, and fermenting; respectively taking 15-20 parts of fermented crop straw and 60-70 parts of fermented poultry manure, mixing the two materials, adding 6-10 parts of a carbon raw material, 10-15 parts of mineral fulvic acid or biochemical fulvic acid and 5-10 parts of attapulgite, uniformly stirring, and adding the mixture into a granulator for production; 3-5 parts of compound probiotics and 3-5 parts of lignic acid are added in the production process; air drying treatment is conducted after production is completed, and 3-5 parts of polyglutamic acid is sprayed in the process to accelerate air drying; the crop straw and the livestock manure are carbonized to serve as the base material of the organic fertilizer, so that the crop straw and the livestock manure can be fermented, and the maximum utilization value is exerted.
Description
technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a method for preparing organic fertilizers by utilizing crop straws. Background technique [0002] Organic fertilizers are mainly derived from plants and animals, and are applied to the soil to provide carbonaceous materials with plant nutrition as their main function. It is processed from biological materials, animal and plant wastes, and plant residues, which eliminates toxic and harmful substances, and is rich in a large number of beneficial substances. Provide comprehensive nutrition for crops, increase and renew soil organic matter, promote microbial reproduction, improve soil, and promote plant growth. [0003] The development of agriculture and animal husbandry has brought a lot of available resources. Livestock and poultry manure and crop straw can be used as raw materials for fertilizer preparation. Due to the unreasonable utilization of resources, livestoc...
