Problems solved by technology

[0003] Although some salt-alkali-resistant fertilizers are disclosed in the prior art, although the short-term effect is obvious in the process of these chemical fertilizers, the chemical fertilizer itself has a short fertilizer period, rapid failure, and poor fertility durability. It will cause secondary chemical pollution to the fragile saline-alkali soil, and the large amount will easily cause soil compaction

Embodiment 1

[0023] The preparation of embodiment 1 microbial fertilizer

[0024] The inventor selected Penicillium bilis, Bacillus subtilis, Bacillus licheniformis and Penicillium oxalium as the raw material bacteria of the microbial inoculum for fertilizer. Aluminum sulfate is used as a soil conditioner, and a mixture of zinc sulfate and boric acid obtained at a mass ratio of 6:4 is used as a trace element supplement. The proportioning ratio of each bacterium in the microbial bacterial agent of the microbial bacterial fertilizer made is as shown in table 1.

[0025] Table 1 Composition of bacterial agents in microbial fertilizer

[0026]

[0027] After preparing the microbial inoculum according to the composition and proportioning in Table 1, the microbial inoculum and the above-mentioned soil conditioner and trace element supplement are combined according to 85% of the microbial inoculum, 10% of the soil conditioner, and 5% of the trace element supplement The mass ratio is mixed to...

Embodiment 2

[0028] Embodiment 2 The improvement of soil pH by microbial fertilizer

[0029] The saline-alkali land soil in the saline-alkali paddy field of Fuyu Farm, Fuyu County, Heilongjiang Province was selected, and the microbial bacterial fertilizer prepared in Example 1 was used to carry out the experiment of improving soil pH by the microbial bacterial fertilizer. Choose the microbial fertilizer that utilizes the bacterial agent 1-6 of embodiment 1 to prepare, add bacterial agent 1-6 respectively in the soil according to the addition of 8 kilograms per mu of land, after 2 days, measure soil pH and compare with the initial value of soil The pH was compared and the results are shown in Table 2.

[0030] Table 2 Effects of microbial agents on soil pH in saline-alkali land

[0031]

[0032] As can be seen from Table 2, the improvement of soil pH is very obvious in the inoculum (microbial agent 2,5 and 6) mixed with Penicillium bilei and Bacillus subtilis, but only applicable...

Embodiment 3

[0033] Example 3 Effect of Microbial Fertilizer on Rice Yield

[0034] In this example, the inventor selected bacterial agent 2 as the bacterial agent of the microbial fertilizer. After the microbial fertilizer was prepared, the bacterial fertilizer was used for field experiments to test the effect of the bacterial fertilizer on rice yield. The prepared fertilizer was sent to the Heilongjiang Quality Supervision and Inspection Institute for the detection of the number of viable bacteria. Among them, the number of viable bacteria per gram of fertilizer in powder bacterial fertilizer reached 624 million, and the number of viable bacteria per gram of bacterial fertilizer in granular bacterial fertilizer reached 2.7 billion. After preparing the inoculum, the inventor took the inoculum to No. 0 saline-alkali land of team 11 of Fuyu Ranch in Fuyu County for rice cultivation experiments. On the basis of normal fertilization, the experimental group added microbial fertilizer at the r...

Abstract

The invention discloses a saline-alkali-resistant microbial fertilizer and its application, belonging to the technical field of agricultural microbial fertilizers. The salt-alkali-resistant microbial fertilizer provided by the invention includes microbial bacterial agents, soil regulators and trace elements. Among them, the microbial agent accounts for 80% to 90% of the total mass of the microbial fertilizer, the soil conditioner accounts for 7% to 12% of the total mass of the microbial fertilizer, and the trace elements account for 3% to 7% of the total mass of the microbial fertilizer; The agent contains Penicillium bilis and Bacillus subtilis. The scientific compatibility of the microbial fertilizer provided by the invention and the soil conditioner can effectively reduce the pH value of the saline-alkali soil, improve the physical environment of the soil, and can replace chemical pesticides at the same time, effectively inhibiting blight of crops. Moreover, the microbial fertilizer can be scientifically compatible with non-legume nitrogen-fixing bacteria. It can fix nitrogen, decompose phosphorus, release potassium and trace elements, and can reduce the application of chemical fertilizers by 20%-30%, without reducing production and pollution, and protecting the existing cultivated land resources.

Description

technical field [0001] The invention relates to a saline-alkali-resistant microbial fertilizer and its application, belonging to the technical field of agricultural microbial fertilizers. Background technique [0002] Saline-alkali land refers to the salt-accumulated land where the salt contained in the soil affects the growth of crops. According to the incomplete statistics of UNESCO and the World Food and Agriculture Organization, the area of ​​saline-alkali land in the world has exceeded 950 million hectares, of which my country has reached 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil. The degree of salinization is generally high, and plants in severe saline-alkali soil areas can hardly survive. [0003] Although some salt-alkali-resistant fertilizers are disclosed in the prior art, although the short-term effect is obvious in the process of these chemical fertilizer...
