Problems solved by technology

[0002] Experimental research results show that if biological fertilizers and chemical fertilizers are used together, in addition to producing their own inherent fertilizer effects, they can also improve the effective utilization of chemical fertilizers, reduce their loss, and produce synergistic effects between each other; what needs to be pointed out here Yes, biological fertilizers cannot be directly mixed with instant chemical fertilizers, because after the instant chemical fertilizers are dissolved in water, a hypertonic solution is formed on the surface of microorganisms, which may lead to the inactivation of microorganisms and the loss of biological fertilizers.
[0003] Currently known technology (such as: Chinese patent application CN 1092397A and CN 1106366A), in addition to microorganisms and instant chemical fertilizers, more organic matter has also been added in the compound fertilizer; Contact, so the activity of microorganisms cannot be fully guaranteed; the added organic matter is limited by the amount of fertilizer applied, and has little effect on the soil. On the contrary, it limits the amount of chemical fertilizers added, thereby reducing the nutrient content of compound fertilizers

Abstract

The invention discloses a biological inorganic complex fertilizer wherein the slow release chemical fertilizer particles are used as the cores, coated by bio-fertilizer and inorganic wrapper, thus realizing the dual functions of bio-fertilizers and chemical fertilizers, the availability for the chemical fertilizers is substantially increased, and the leak rate is reduced.

Description

technical field [0001] The invention relates to a compound fertilizer of microbial fertilizer and chemical fertilizer, in particular to a biological-inorganic compound fertilizer. Background technique [0002] Experimental research results show that if biological fertilizers and chemical fertilizers are used together, in addition to producing their own inherent fertilizer effects, they can also improve the effective utilization of chemical fertilizers, reduce their loss, and produce synergistic effects between each other; what needs to be pointed out here Yes, biological fertilizers cannot be directly mixed with instant chemical fertilizers. This is because the instant chemical fertilizers dissolve in water and form a hypertonic solution on the surface of microbial cells, which may lead to the inactivation of microorganisms and the loss of biological fertilizers. [0003] Currently known technology (such as: Chinese patent application CN 1092397A and CN 1106366A), in additio...
