Problems solved by technology

However, the traditional method of applying chemical fertilizers not only causes damage to the environment, but also often has unsatisfactory effects. With the increase in the price of chemical fertilizers year by year, the large-scale application of chemical fertilizers also increases the economic burden of farmers, which is not conducive to the development of agricultural economy.

preparation example Construction

[0033] According to a preferred embodiment of the present invention, wherein, the preparation method of the compound fertilizer comprises: mixing the active components with auxiliary materials, and then performing sealed composting for 30-50 days, preferably 30-45 days.

[0034] Preferably, the composting conditions include a humidity of 50-70% and a temperature of 60-75°C.

[0035] According to a preferred embodiment of the present invention, wherein, the preparation method of the compound fertilizer further includes turning the compost during the composting process.

[0036] Preferably, the turning is performed 1-3 times during the composting process.

[0037] More preferably, the turning is performed every 10-15 days during the composting process.

[0038] The third aspect of the present invention provides that the above-mentioned organic carbon fertilizer and / or the above-mentioned compound fertilizer are effective in promoting soil biological activity (for example, promo...

Embodiment 1

[0051] Take 500kg of fresh cow dung, 1500kg of air-dried pine needles, and 20.55kg of urea, then mix and stack the above materials, and seal them tightly with mud after stacking. During composting, control the moisture content in the compost material to 55±5%, and the temperature to be 65±5°C. On the 15th day and the 30th day of composting, the compost was turned once. Composting lasts for 40 days to obtain compound fertilizer A1.

Embodiment 2

[0053] Take 500kg of fresh cow dung, 1000kg of air-dried pine needles, and 13.55kg of urea, then mix and stack the above materials, and cover them with plastic cloth after stacking. During composting, control the moisture content in the compost material to 52±5%, the temperature to 70±5°C, and turn the compost once on the 15th and 30th days of composting. Composting lasts for 35 days to obtain compound fertilizer A2.

Abstract

The invention relates to the technical field of agricultural ecology, and discloses an organic carbon fertilizer with a function of improving soil biological activity, which is characterized in that the organic carbon fertilizer contains cow dung and pine needles, and the weight ratio of cow dung to pine needles is 1: 1-30 based on dry matter. The organic carbon fertilizer provided by the invention is green and environment-friendly, and can be applied to soil to effectively improve the biological activity of the soil, so that the adjustment of the carbon-nitrogen cycle balance of the soil is realized, the nitrogen loss is reduced, and the optimal management and agricultural sustainable development of a farmland ecosystem are realized.

Description

technical field [0001] The invention relates to the technical field of agricultural ecology, in particular to an organic carbon fertilizer and compound fertilizer capable of improving soil biological activity and applications thereof. Background technique [0002] Nitrogen loss in farmland soil is one of the important causes of water eutrophication. Studies have shown that the existence of high carbon pools in soil can form a good carbon dam to block nitrogen loss, thereby realizing the control of nitrogen loss. Water pollution and deterioration of farmland soil quality. The soil microbial community structure and its function, that is, soil biological activity, are important factors affecting the carbon-nitrogen mutual aid effect. [0003] In the soil ecosystem, soil microorganisms can have an important impact on many important ecosystem functions including soil carbon and nitrogen cycles, and are important maintainers and contributors to the material cycle of the soil and ...
