Abstract

The invention discloses a green micro-ecological compound fertilizer and a preparation method thereof. The green micro-ecological compound fertilizer is prepared from the following raw materials in parts by weight: 30-60 parts of a bio-organic fertilizer base material, 8-20 parts of liquid biological bacteria, 5-18 parts of modified starch and 18-25 parts of aerated concrete powder. The micro-ecological compound fertilizer has the characteristics of greenness, environment-friendliness and high efficiency. Besides, the aerated concrete powder and the modified starch are added into the compound fertilizer. A large number of micro-pores are formed in the surface and the interior of the aerated concrete powder, and the aerated concrete powder can serve as a filling carrier of organic fertilizer and biological bacteria. The modified starch, on one hand, plays a role in bonding, and on the other hand, the ionic groups in the modified starch are matched with the aerated concrete powder to form a spatial net-shaped structure, so that organic fertilizer and biological bacteria in the fertilizer particles are fully fixed and cannot directly collapse and lose when encountering water, and the micro-porous structure can always keep stable emission of the fertilizer, so that the environmental tolerance of the compound fertilizer is effectively improved, and the long-term stability of the fertilizer efficiency is ensured.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer production, in particular to a green micro-ecological compound fertilizer and a preparation method thereof. Background technique [0002] Microbial fertilizer is a microbial living product that uses microbial life activities and its products to cause crops to obtain specific fertilizer effects. It can fertilize soil, improve fertilizer utilization, inhibit crops from absorbing harmful substances such as heavy metals and pesticides, and purify and repair soil. It plays an irreplaceable role in promoting the utilization of crop straw and urban waste, and improving the quality of agricultural products. The efficacy of microbial fertilizers is mainly achieved through the synergistic effect on traditional chemical fertilizers and organic fertilizers, the improvement and activation of soil, and the physiological effects of microorganisms. Therefore, microbial fertilizers have a variety of f...
