Embodiment 1

[0070] Take 1 part of hydroquinone, 2 parts of NAM, 0.5 part of multidimensional fertilizer essence and 1 part of nano-carbon in parts by weight, and mix uniformly to become the mixed synergist for improving the utilization rate of rice fertilizer of the present invention.

[0071] When in use, the mixed synergist prepared above is uniformly mixed with a nitrogen fertilizer whose pure nitrogen amount is 100 parts by weight to become a mixed nitrogen fertilizer, and then used in a conventional method.

Embodiment 2

[0073] Take 3 parts of hydroquinone, 1 part of NAM, 1.2 parts of multidimensional fertilizer essence, and 0.5 part of nano-carbon respectively in parts by weight, mix uniformly, and become the mixing synergist for improving the utilization rate of rice fertilizer of the present invention.

[0074] When in use, the mixed synergist prepared above is uniformly mixed with a nitrogen fertilizer whose pure nitrogen amount is 100 parts by weight to become a mixed nitrogen fertilizer, and then used in a conventional method.

Embodiment 3

[0076]Take 2 parts of hydroquinone, 1.6 parts of NAM, 0.85 parts of multidimensional fertilizer essence, and 0.65 parts of nano-carbon in parts by weight, and mix evenly to become the mixed synergist for improving the utilization rate of rice fertilizer of the present invention.

[0077] When in use, the mixed synergist prepared above is uniformly mixed with a nitrogen fertilizer whose pure nitrogen amount is 100 parts by weight to become a mixed nitrogen fertilizer, and then used in a conventional manner.

[0078] The mixed synergist for improving the utilization rate of rice fertilizer is a mixed synergist for improving the utilization rate of rice fertilizer and reducing the loss of nitrogen and phosphorus nutrients, and is suitable for application when planting early and late rice.

Abstract

The invention discloses a mixing synergist capable of improving the utilization rate of a rice fertilizer, and a use method of the mixing synergist, relating to the technical field of fertilizers used by rice planting. The mixing synergist is prepared by the following raw materials in parts by weight: 1-3 parts of a urease inhibitor, 1-2 parts of a long-acting compound fertilizer additive, 0.5-1.2 parts of a synergist, and 0.5-1 part of nano carbon. The mixing synergist has the characteristics of improving the utilization rate of the rice fertilizer and the grain yield, reducing the flow rate of nitrogen and phosphorus of a farmland to a water body and soil, and controlling the agricultural non-point source pollution generated by the farmland from the source and the like. The mixing synergist capable of improving the utilization rate of the rice fertilizer provided by the invention is a mixing synergist capable of improving the utilization rate of the rice fertilizer and reducing the nitrogen and phosphorus loss, and is suitable for being applied in early and late rice planting.

Description

technical field [0001] The invention relates to the technical field of fertilizers used in rice planting, in particular to a mixed synergist for improving the utilization rate of rice fertilizers and a use method thereof. Background technique [0002] my country is a country with many people and little land, and the contradiction between people and land is serious. High crop yield has been emphasized for a long time, and the total crop yield is often increased by increasing the amount of fertilizer and the multiple cropping index. According to statistics, my country is the largest producer and user of chemical fertilizers in the world, with an annual chemical fertilizer application of 57 million tons (converted to purity), accounting for 35% of the world's total. Calculated on the basis of the national arable land area (the multiple cropping index is calculated at 120%), the average amount of chemical fertilizer per mu is 18.5kg, which is 2.8 times the world average level. ...
