Embodiment 1

[0051] Example 1. Preparation and Application of All Organic Straw Granular Fertilizer Planting Spring Corn

[0052] 1. Preparation of fermented residue and concentrated fermented liquid:

[0053] Crush crop stalks (wheat, corn, and peanut stalks in a ratio of 2:2:1) to a size below 1.5cm, add orange peels that account for about 15% of the straw mass, and add sugar industrial wastewater (requires that all solid substances be submerged in water), sealed and fermented for 90 days.

[0054] Dry and grind the fermented residue for later use.

[0055] The fermented liquid is distilled and concentrated, and the specific method is to filter the separated fermented liquid, and then place the filtered liquid in a reverse osmosis membrane separation system for membrane distillation, and the distilled liquid is a concentrated fermented liquid.

[0056] 2. Preparation of straw vinegar liquid: mix corn straw, wheat straw, rice straw, and sorghum straw in a ratio of 1:1:1:1 in a retort fo...

Abstract

The invention discloses all-organic straw granular fertilizer and a preparation method thereof. The all-organic straw granular fertilizer is prepared through mixing and granulation of the following components: in parts by mass, 20-51 parts of straw powder, 10-15 parts of fermentation slag, 5-8 parts of dry powder of pomelo peels, 3-5 parts of dry powder of celastrus orbiculatus root peels, 5-8 parts of walnut skin powder, 3-5 parts of bran, 8-12 parts of water hyacinth dry powder, 5-10 parts of spartina alterniflora dry powder, 5-10 parts of ageratina adenophora dry powder and 3 parts of diatomaceous earth. The all-organic straw granular fertilizer has the characteristics of multiple effects, has fertilizer supply, de-worming, pest killing, sterilization and other functions, and is prepared from all organic substances.

Description

technical field [0001] The invention relates to an all-organic straw granular fertilizer and a preparation method thereof, belonging to the technical field of biological fertilizers in the agricultural field. Background technique [0002] my country has a large population and little land, and the pressure on food production is high. With the growth of population, the development of industry and urbanization, the cultivated land in our country is decreasing year by year. Increasing the grain production per unit area has become an important way to ensure our country's food security. Over the years, my country has mainly relied on the application of chemical fertilizers to increase the output of agricultural products. However, with the increase in the amount of chemical fertilizers used, its contribution to food production has decreased. increased by 61%, while grain production increased by only 31%. At the same time, the utilization rate of chemical fertilizers is also reduced...
