The fulvic acid is a high molecular organic compound with small molecular weight of humic acid, contains various active functional groups, has strong biological activity, is easy to be absorbed by plants, is acidic, can improve the activity of attapulgite, increases the water absorption expansion rate of the attapulgite, stimulates the growth and development of the plants, improves the immunity of the plants, resists cold and diseases, can improve the fertility condition of soil nutrients by fruit and vegetable wastes, straws and livestock and poultry manure, provides carbon and nitrogen sources required by microbial growth, and is an ideal material for improving salinized soil by matching the attapulgite. The fulvic acid is produced by taking agricultural and sideline product processing waste, agricultural straws, livestock and poultry manure and the like as raw materials and carrying out compound fermentation by using a compound microbial inoculum, and the fulvic acid mainly comprises fulvic acid, amino acid, organic matters and nucleic acid, and is matched with other biological essential elements and nutritional ingredients, so that the immunity and the stress resistance of plants can be obviously improved, and the soil salinization degree can be improved.
The silicate bacteria can decompose silicon in the attapulgite and provide sufficient silicon element for crops. The bacillus mucilaginosus belongs to silicate bacteria, has strong strain activity, high temperature resistance, acid and alkali resistance, fast propagation and strong applicability, can decompose insoluble silicon and other medium and trace elements in attapulgite, and provides necessary nutrient elements for plants.
The attapulgite biological organosilicon fertilizer of the embodiment is applied to Gansu Zhangye saline-alkali soil, and the result shows that: when the application amount of the attapulgite biological organosilicon fertilizer is 4 thm-2、8t hm-2And 12 thm-2The yield of the corn planted in the saline-alkali soil is 11453kg hm-2、15476kg hm-2And 16161kg hm-2Highest ratio control (11291kg hm)-2) The yield is increased by 30.1 percent. The physical structure and fertility indexes of soil in a test area show that the average weight diameter of soil aggregates in the test area treated by the attapulgite bio-organic silicon fertilizer is up to 4.70mm, which is increased by 17.9% compared with a control (3.86 mm); the cation exchange capacity of the soil reaches 35.63cmol +/kg at most, and is increased by 8.9 percent compared with a control (32.45cmol +/kg); the pH value of the soil is reduced to 8.54 which is 7.1 percent lower than that of a control (9.19); the organic matter content of the soil reaches 10.98g kg at most, which is increased by 41.0 percent compared with the control (6.48g kg).
The attapulgite biological organic silicon fertilizer can adjust the pH value of soil, improve the content of organic matters in the soil and improve the micro-ecological environment of the soil by increasing the stability of soil aggregates and the cation exchange capacity, thereby improving the saline-alkali soil, improving the soil quality and increasing the corn yield.
The attapulgite bio-organic silicon fertilizer is implemented according to the agricultural industry standard NY 884-.
The attapulgite bio-organic silicon fertilizer has the advantages of rich raw material resources, low cost, simple manufacturing process, low energy consumption and no need of special conditions; the production process is harmless to human bodies, has no pollution to the environment, has low cost of farmland application, good effect and no harmful residues, and can effectively improve soil and recover soil fertility; the fertilizer is convenient to use, has no special requirements as the use method of the traditional fertilizer, can improve the nutrient utilization rate, reduce the application amount of the fertilizer, effectively stimulate the growth of plants, improve the yield and the quality of crops, has good comprehensive effect, is a win-win measure which gives consideration to the resource utilization of wastes and the research and development of novel environment-friendly fertilizers, and has far-reaching significance for further perfecting the existing ecological cycle agricultural mode in agricultural application.
The above is an embodiment of the present invention. The embodiments and specific parameters in the embodiments are only for the purpose of clearly illustrating the process of verifying the invention and are not intended to limit the scope of the invention, which is defined by the claims, and all the equivalent structural changes made by applying the content of the specification of the invention should be covered by the scope of the invention.
