Biological organic fertilizer

Abstract

The invention discloses a biological organic fertilizer which comprises the raw materials as follows: organic matters, available nutrients, lime, dried blood, bone meal and strains. The biological organic fertilizer can slow down the vicious circle of environmental quality so as to use the cultivated lands sustainably for a long time; can meet the proportioning demand of plants to nutrients, and the organic matters further absorb and store the available nutrients added to realize the effect of slow release and sustained release so as to reduce the loss of the available nutrients such as permeation, fixation, volatilization and the like. The organic matters can further improve the physicochemical properties of soils under repeated effect of soil microorganisms so as to enhance the fertilizer and water conservation capacity of soils.

Description

technical field

[0001] The invention relates to the field of agricultural technology, in particular to a biological organic fertilizer. Background technique

[0002] At present, the area of ​​fruit and vegetable planting in rural areas is increasing, the amount of livestock breeding is decreasing, and the fertilizers for crops mostly rely on inorganic chemical fertilizers as base fertilizers and topdressing fertilizers, resulting in the reduction of soil organic matter, the decline in fertilizer and water retention performance, and a large amount of nutrients applied to the soil permeate and lose , fixed or volatilization loss, excessive accumulation of heavy metal elements, and undegradable chemical pesticides for pest control and disease treatment, resulting in excessive pesticide residues. The agricultural products grown in the above situations not only directly threaten the health of consumers, but also cause a vicious circle in the quality of the soil environment. . ...
