Problems solved by technology

[0005] However, my country has made some progress in the research and development of nitrogen fertilizer synergists on rice, but there are still unstable yield-increasing effects, and poor adaptability to different soils, different nitrogen source fertilizers, different planting systems, and different climate characteristics. However, most of the research has focused on the development of synergist formulas, and there are no related technologies and patents on the research on the amount of compound application in the formula fertilizer for the southern double-cropping rice area on the basis of the existing synergist formulas.

Embodiment 1

[0028] Fertilizer preparation in the field is as follows: take 100 kg of nitrogen fertilizer, phosphate fertilizer and potash fertilizer by weight, and take 18 kg of nitrogen fertilizer (calculated as pure N) and 0.6-0.7 kg of compound synergist (NAM) in the mixer Mix and stir, if the nitrogen fertilizer is granular urea, just make the compound synergist (NAM) evenly coat the surface of the urea for about 3-5 minutes, and then let it stand for about 10 minutes to get a long-acting slow-release nitrogen fertilizer, which will contain available phosphorus 8 kg of phosphate fertilizer (in P 2 o 5 Calculated), potassium fertilizer containing 23 kg of available potassium (in K 2 (2 meter) and 1-3 kilograms of multivariate micro-fertilizers (trace elements in silicon, zinc, boron, magnesium, calcium) are added in the blender simultaneously and continue mixing for 3-5 minutes to obtain finished fertilizer.

Abstract

The invention relates to the field of fertilizer production, particularly application of a composite synergist into Southern double cropping rice. The composite synergist NAM (N-acetylmuramic acid) is used as a synergist applicable to slow release fertilizers for Southern double cropping rice seedlings. After the composite synergist is compounded with the slow release fertilizer, the compound fertilizer applied to the Southern double cropping rice field can greatly enhance the rice yield, is convenient for production and use, obviously reduces the greenhouse gas emission in the rice field, lowers the nitrate pollution, and has the advantages of strong technical compatibility, low cost and the like. The invention can receive favorable economic, social and ecological effects.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to the application of a compound synergist to southern double-cropping rice. Background technique [0002] Rice is one of the most important food crops in China and has an important strategic position in China's food production. According to statistics, my country's rice area accounts for about 29% of the total area of ​​grain crops, and its total output accounts for 44% of the country's total grain output. More than 90% are concentrated in the southern rice-growing areas, of which double-cropping rice accounts for a quarter of the country's rice planting area. More than one, mainly concentrated in four provinces including Jiangxi, Hunan, Guangdong, and Guangxi. [0003] Rice is also one of the crops that require the most fertilizer. The average amount of nitrogen applied to rice per season in my country is 180kg / hm 2 , About 75% higher than the world's average rice field consu...
