Problems solved by technology

[0004] Although the beneficial effects of nano-micronutrient fertilizers on plant growth are significant, it is difficult to promote and apply them on a large scale due to the constraints of production technology and cost.
At present, nano-micro-element fertilizers are mainly single-element fertilizers produced by physical or chemical methods. They are added to macro-element fertilizers and applied as base fertilizers, which fail to exert the nano-effects of nano-fertilizers.

Embodiment 1

[0019] A preparation method of rice composite nano-matrix fertilizer, the steps are as follows:

[0020] (1) Add 10.3g of anhydrous sodium molybdate, 12.3g of anhydrous magnesium sulfate, 34.1g of anhydrous zinc sulfate, 5.7g of anhydrous manganese sulfate, 6.2g of anhydrous zirconium nitrate, and 7.5g of anhydrous lanthanum nitrate into 100ml Dissolve in aqueous solution and set aside;

[0021] (2) Slowly add 10mol / L sodium hydroxide to the mixed solution obtained in step (1), adjust the pH of the solution to 8, precipitate the trace element ions in the solution, and leave it for 1 hour;

[0022] (3) centrifuging or filtering the medium and trace element ion precipitation obtained in step (2) to obtain the hydroxide of the medium and trace element, and drying at 100 degrees, and grinding through a 400-mesh sieve;

[0023] (4) The medium and trace element hydroxide obtained in step (3) was calcined at 450 degrees for 3 hours to obtain 10% molybdenum trioxide, 17% magnesium ox...

Embodiment 2

[0025] Add 5g of composite nano-matrix fertilizer into 10L rice pad seedling raising matrix, stir evenly and spread it on the rice pad seedling raising tray, and evenly sow 120g soaked, sterilized and germinated rice seeds (the rice variety is Nanjing 9108) with the seeding tray. ), darkened for 2 days after watering, and placed in the seedling field to raise seedlings normally according to farmers' habits. At the same time, a control treatment without the application of composite nano-matrix fertilizer was set. At the three-leaf-one-heart stage of rice seedlings, samples were taken to determine the physical and chemical properties of the roots and plants. The results showed that after the application of the composite nano-matrix fertilizer, the rice root coiling ability increased by 31.3%, the root length and the total root system increased by 68.2% and 53.6%, respectively, and the seedling height and dry matter weight increased by 8.1% and 53.6%, respectively, compared with ...

Abstract

The invention provides rice composite nano matrix fertilizer and a preparation method thereof, and belongs to the technical field of agricultural nano fertilizer. The rice composite nano matrix fertilizer is prepared from the following nano oxide components in percentage by weight: 5%-15% of nano-molybdenum, 10%-20% of nano-magnesium, 20%-30% of nano-zinc, 5%-15% of nano-manganese, 5%-15% of nano-zirconium and 5%-15% of nano-lanthanum. According to the rice composite nano matrix fertilizer and the preparation method thereof, the composite nano matrix fertilizer is used for providing abundant medium trace element nutrients for rice carpet seedlings, the nano-size effect of a nano matrix is used for inhibiting or killing pathogenic bacteria in a raising seedling matrix or rice seeds, the disease-resistant and stress-resistant capacity of the rice carpet seedlings is improved, development of root systems of the rice carpet seedlings is promoted, and the elongation capacity and winding capacity of the root systems are improved. The composite nano matrix fertilizer brought to a field with roots can stimulate the damaged rice seedling root systems, provide a good root micro-ecological environment for the seedlings, promote absorption of the root systems for large, medium and small microelements, and solve various element deficiency symptoms of the seedlings.

Description

technical field [0001] The invention belongs to the technical field of agricultural nano-fertilizers, and relates to a composite nano-matrix fertilizer composed of medium and trace elements and a preparation method thereof, in particular to a rice composite nano-matrix fertilizer and a preparation method thereof. Background technique [0002] Rice is the main ration crop in my country, and its stable and high yield is the key to ensuring food security in my country. Machine transplanting of rice blanket seedlings is the main machine transplanting technology in my country at present. Its main feature is to use standard machine transplanting trays to cultivate standardized blanket-shaped seedlings. insert. In order to ensure the quality of machine transplanting, the seedlings used for machine transplanting are mainly small and medium-sized seedlings, generally requiring a seedling age of 15-20 days and a seedling height of 12-18 cm. Blanket seedling machine transplanting tech...
