Problems solved by technology

Long-term unreasonable fertilization has caused a serious shortage of trace elements in the soil, low soil fertility, and a sharp drop in the number of microorganisms. The utilization rate of chemical fertilizers is less than 30%, and waste and pollution are very serious
However, the types of microorganisms that decompose nutrients in the soil are insufficient, and they cannot interact well with the minerals in mineral fertilizers. The growth and reproduction of microorganisms is slow, resulting in slow decomposition of mineral fertilizers, and both microorganisms and crops cannot fully utilize medium and trace elements. , unable to form a virtuous circle, crops are still unsatisfactory in terms of growth, yield and reduction of disease incidence

Embodiment 2

[0032] Embodiment 2: the effect test of microbial bacterial type mineral fertilizer of the present invention to watermelon

[0033] 1. Test groups

[0034] Be divided into the bacterial mineral fertilizer that embodiment 1 prepares, mineral fertilizer (medicine stone powder of embodiment 1), microbial strain (same as in embodiment 1) and the microbial bacterial type mineral fertilizer (preparation) that does not add humic acid Method with reference to embodiment 1) and blank control 5 groups, the conventional compound fertilizer that each group uses is identical, and blank control group only uses compound fertilizer;

[0035] 2. Test method

[0036] The soil in the same environment was randomly divided into 5 test areas with the same area, and all the above 5 groups of fertilizers were applied as base fertilizers before sowing. During the growth process of watermelon, various physiological indicators and disease indexes of watermelon seedlings were counted, and the yield was...

Abstract

The invention relates to the technical field of agriculture and discloses a microbial type mineral fertilizer and a preparation method of the microbial type mineral fertilizer. The microbial type mineral fertilizer disclosed by the invention comprises the following components by weight: 35-70% of medical stone powder, 10-25% of microbial strains and 20-30% of humic acid or humate or mixture of the humic acid and the humate. According to the invention, a novel microbial type mineral fertilizer is prepared by taking microbial strains (such as bacillus subtilis, bacillus jelly and the like), a mineral fertilizer and humic acid (humate) as raw materials, and the fertilizer can accelerate the multiplication rate of the microbial strains, realize slow release and controlled release of secondary and trace elements and regulate soil nutrients, thereby reducing the incidence rate of diseases of crops and improving the yield of crops.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a microbial bacterial type mineral fertilizer and a preparation method thereof. Background technique [0002] Soil is an essential and important resource in agriculture. It is through the soil that crops obtain water and absorb nutrients, complete photosynthesis, and transform inorganic matter into green organic matter. In today's agricultural field, in order to ensure high yields, it has become normal to apply chemical fertilizers, pesticides, hormones, herbicides, etc. to crops, but the long-term use of these chemicals has caused serious pollution of soil resources, making the nutrients in the soil unbalanced, The types of microorganisms are constantly decreasing, and they cannot decompose various nutrients in the soil for crops to use, resulting in a decline in soil fertility, which eventually leads to limited growth of crops, frequent occurrence of diseases, and reduced y...
