Problems solved by technology

However, in practical applications, it is found that the decomposition of urea-formaldehyde is related to microorganisms and is affected by temperature and humidity, and urea-formaldehyde is not suitable for dryland crops; nitrase inhibitors and urease inhibitors are not suitable for paddy fields or areas with a lot of precipitation, because water will reduce The concentration of nitrase and urease inhibitors reduces the effectiveness; moreover, such products do not have the function of reducing urea loss

Abstract

The invention relates to a wheat stress-resistant physiological slow-release fertilizer synergist, a preparation method and applications thereof, wherein the synergist comprises: 450-550 g / L polymericamino acid salt-organic acid salt complex, 20-100 g / L nitrogen synergist, 30-120 g / L phytohormone, and 4-20 g / L trace element. The preparation method comprises: dissolving potassium hydroxide in water, sequentially adding polymeric amino acid, an organic acid, sequentially adding a nitrogen synergist, phytohormone and trace element, and carrying out volume metering with water. According to the present invention, by adding the synergist to the fertilizer, the nitrogen loss of soil can be effectively reduced, the utilization rate of fertilizers can be increased, the nitrogen metabolism processof plants can be improved, the utilization rate of the nitrogen fertilizer can be improved, and the stress resistance, the yield and the quality of wheat can be improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a stress-resistant physiological slow-release fertilizer synergist for wheat and its preparation method and application. Background technique [0002] Fertilizer is an important means of production for the development of the agricultural industry, and it plays an irreplaceable role in promoting high-quality, high-yield and stable yields of crops and ensuring food security. Chemical fertilizers are the "grain" of food crops, and there is a linear relationship between food production and the amount of chemical fertilizers used. In order to increase the crop yield per unit area, the amount of soil fertilization has increased year after year. Statistics show that in the past two decades, the amount of chemical fertilizers used in my country has increased from more than 38.5 million tons to 63.487 million tons; so far, my country's chemical fertilizer use accounts for 31% of the ...
