Description
Technical Field
The invention belongs to a microbial fertilizer, and particularly relates to a special biological organic fertilizer for saline-alkali soil and a preparation method thereof.
Background
The saline-alkali soil is a kind of salt accumulation, which means that the salt contained in the soil influences the normal growth of crops, and according to the incomplete statistics of the textbook organization and the grain and agriculture organization of the united nations, the area of the saline-alkali soil all over the world is 9.5438 hundred million hectares, wherein 9913 million hectares are in China. The formation of alkaline earth and alkalized soil in China is mostly related to the accumulation of carbonate in soil, so that the alkalization degree is generally high, and plants in serious saline-alkaline earth regions can hardly survive. In addition, China also has a continental coastline which is 18000 kilometers more and long, and coasts such as Bohai sea, yellow sea and east sea coastal plain, and large areas of coastal saline soil mainly containing chloride are distributed, and the common characteristics of the areas are that the soil quality and the salt content are high, and most of the areas are not rough places where plants are difficult to grow.
The saline-alkali harm causes a large number of medium-and low-yield fields and poor farmers, and large-area soil resources are difficult to utilize. China's per capita cultivated land is less than 1/3 which is the world average cultivated land, and is facing great pressure of dramatic population increase and sharp cultivated land reduction, and saline-alkali land is inevitably involved in both improving the unit area yield of the existing cultivated land and planning to reclaim wasteland.
The fertilizer is grain of crops, and the reasonable application of the fertilizer is one of important factors for ensuring the high and stable yield of the crops and promoting the full development of agriculture in China. The fertilizer is mainly divided into inorganic fertilizer and organic fertilizer, wherein the inorganic fertilizer is also called chemical fertilizer, such as nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and the like. In modern agriculture, as a large amount of chemical fertilizers and pesticides are used in pursuit of agricultural high yield, the chemicals are applied to soil, so that the physical and chemical properties and biochemical properties of the soil are rapidly deteriorated, soil hardening and hardening are realized, microorganisms are eliminated, the loss of organic matters is serious, the soil fertility is reduced, the fertilization effect is poor, crop diseases are frequent, and the original soil loses natural ecological balance. The organic fertilizer can effectively improve soil nutrients, increase soil organic matters and fertility, reduce pesticide application, prevent agricultural products from being polluted, optimize soil ecological environment, and improve the quality and taste of the agricultural products to return to nature.
Disclosure of Invention
Aiming at the problem of less per capita cultivated land in China, and combining the improvement effect of the organic fertilizer, the invention provides the special biological organic fertilizer for the saline-alkali soil, and by means of a layered structure, after the saline-alkali soil is improved, nutrition is provided for crop growth in different periods, and finally the purposes of optimizing the soil ecological environment and improving the quality and taste of agricultural products to return to nature are achieved. In addition, the invention also provides a preparation method of the biological organic fertilizer.
The technical scheme of the invention is as follows:

The microbial agent comprises: a mixture of rhizobium inoculant, organic material decomposing agent and bioremediation inoculant.
The preparation method of the special biological organic fertilizer for the saline-alkali soil comprises the following steps:
(1) corncob meal, alginate, K2HPO4Mixing ferric ammonium citrate and fatty alcohol, adding a small amount of water to form granules;
(2) carrying out high-temperature aerobic fermentation on the livestock manure and a microbial agent;
(3) adding the particle type obtained in the step (1) into the step (2), adding part of polyacrylamide, and forming;
(4) putting the particles formed in the step (3) into humic acid soil, adding the rest polyacrylamide, and performing compression molding; the product is obtained.
Preferably, the polyacrylamide added in the step (3) accounts for 1/3-1/2 in total.
The application method of the special biological organic fertilizer for saline-alkali soil prepared by the preparation method comprises the following steps:
s1, uniformly scattering aluminum sulfate powder and corn pellets with the grain size of 2-10cm on the surface of soil; irrigating and soaking for 20-40 hours;
s2, draining the water in the saline-alkali soil;
s3, collecting the corn pellets on the surface to one side; applying a special biological organic fertilizer for saline-alkali soil;
and S4, sowing.
Preferably, the aluminum sulfate powder used in step S1 is: 15-40 kg/mu.
Preferably, the usage amount of the special bio-organic fertilizer for saline-alkali soil in the step S3 is as follows: 60-80 kg/mu.
The corncob meal can be adsorbed and stored under the condition of sufficient water and nutrient components, and can supply water and nutrients to crops under the condition of insufficient water and nutrient components, thereby playing the role of slow release of fertilizer efficiency. The corn cob powder, the humic acid soil and the fatty alcohol (hydroxyl and surfactant) generate a synergistic effect, so that the hydrolysis of the ferric ammonium citrate and the alginate is promoted, and nutritional ingredients are continuously provided for the growth of crops.
The invention has the advantages of
1. By means of the layered structure, after the saline-alkali soil is improved, nutrition is provided for crop growth in different periods. The humic acid soil on the surface layer improves the alkalinity of soil, and polyacrylamide has strong flocculation effect and can be adsorbed and bridged among tiny particles; meanwhile, polar group particles on the polyacrylamide can also adsorb a plurality of ions, so that the fertilizer retention of the soil is enhanced. The fermented livestock and poultry manure is rich in nutrition and provides nutrition for the budding period; the corn cob powder, the humic acid soil and the fatty alcohol (hydroxyl and surfactant) generate a synergistic effect, so that the hydrolysis of the ferric ammonium citrate and the alginate is promoted, and nutritional ingredients are continuously provided for the growth of crops.
2. The corncob powder is favorable for air circulation, increases the water holding capacity of soil, and provides a good living space for animals and microorganisms with different sizes and body types and aerobic and anaerobic life habits, so that the corncob powder is favorable for water retention, fertilizer retention, ventilation and promotion of plant root system development, improves the utilization rate of soil moisture, and provides a comfortable growing environment for crops in saline-alkali soil.
3. The saline-alkali soil is improved, and the low-yield field in the saline-alkali soil is favorably improved. The corn cob meal, the microbial agent and the humus which are rich in the corn cob meal, the microbial agent and the humus can improve the physical properties of soil and increase the granular structure of the soil, the pores among granules are increased by more than 80%, and the small pores in the granules are increased by more than 50%, so that the saline-alkali soil is loosened, and the hardening of the saline-alkali soil is reduced.
