Problems solved by technology

[0003] The granular organic-inorganic compound fertilizer produced by Chinese patent 92102853.9 uses sheep pen manure or peat, rapeseed cake (cotton seed cake) and the like as organic components directly, and these organic materials are not harmless and stabilized through high-temperature composting Therefore, the pathogenic bacteria, weed seeds and eggs contained in it have not been killed, and they have not reached maturity and stability

Embodiment 1-4

[0029] Embodiment 1-4 prepares active compost

[0030] Crush crop stalks into 2-5cm long pieces, measure the water content and carbon and nitrogen percentages of straw and livestock manure (as shown in Table 1-4), and satisfy the C / N requirement of 20-35 Calculate the actual mixing ratio of straw and poultry manure (as shown in Table 1-4) according to the conditions, and then mix the two while adjusting the moisture content to 60%. When the final C / N is low and the moisture content of the mixed material exceeds 60% (see Table 1), the moisture can be reduced by appropriately increasing the number of turning times in the subsequent high-temperature composting process without affecting the composting effect. Using modern high-temperature composting technology, the semi-decomposed compost ( It mainly refers to the pathogenic bacteria and weed seeds that have been completely killed, and at the same time have a certain degree of humification), dried and crushed for later use.

Abstract

The remixed organic-inorganic fertilizer with active compost as basic material is produced with the following matters: fermented active compost in 30-50 weight portions, urea 10-30 weight portions, ammonium or diammonium phosphate 10-20 weight portions, potassium chloride or potassium sulfate 15-25 weight portions, and adhesive 0.6-15 weight portions. The active compost is prepared through crushing crop stalk, mixing the stalk with animal excrement in such ratio as to result in C / N ratio of 20-35, regulating water content to 60 %, fermentation, stoving and crushing. The preparation process of the remixed organic-inorganic fertilizer is also disclosed. The present invention has obvious environment and economic utility.

Description

technical field [0001] The invention relates to an organic-inorganic compound fertilizer, in particular to an organic-inorganic compound fertilizer based on active compost, which adopts compost that meets the stabilization requirements after fermentation and decomposing of crop straw and livestock and poultry manure as raw materials , and supplemented with other stabilized organic fertilizers and inorganic fertilizers through mixing and granulation. Background technique [0002] China is a large agricultural country, and it is also the largest producer and consumer of chemical fertilizers in the world today. Nitrogen, phosphate, potash and trace element fertilizers have been applied in my country for a long time. However, due to the unreasonable structure of chemical fertilizers for a long time, although the amount of fertilization per unit area has exceeded the world average by 1.6 times, the nutrient utilization rate has been very low. Low, for example, the utilization rat...
