Abstract

The invention belongs to the technical field of water-soluble fertilizers, and particularly relates to a high-nitrogen water-soluble fertilizer for topdressing before flowering as well as a preparation method and application thereof. The high-nitrogen-containing water-soluble fertilizer comprises the following raw material components by weight: 700 to 750 parts of citrus processing waste fermentation liquor, 150 to 155 parts of monopotassium phosphate, 80 to 85 parts of sodium nitrate, 200 to 230 parts of urea, 26 to 30 parts of water-soluble phosphorus pentoxide, 7 to 9 parts of sodium hydroxide, 80 to 120 parts of potassium humate, 5 to 11 parts of an emulsifier, 5 to 11 parts of a scale remover and 1 to 2 parts of a synergist. The high-nitrogen water-soluble fertilizer based on the citrus processing waste fermentation liquor does not flocculate or crystallize and separate out at low temperature after being placed for a long time, promotes the growth and development of crops, and improves the absorption and utilization of nutrients. The humic acid-containing high-nitrogen water-soluble fertilizer has the advantages of simple preparation process, low cost and suitability for rapid and large-scale production, can improve nutrient absorption when being used for topdressing before flowering in the early stage of crop growth, is beneficial to stem and leaf growth, promotes photosynthesis, and realizes yield increase and efficiency improvement.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizers, and in particular relates to a high-nitrogen water-soluble fertilizer for topdressing before flowering, a preparation method and application thereof. Background technique [0002] Hunan's citrus production ranks first in the country. In the dominant citrus producing areas of western and southern Hunan, navel oranges, ponkans, rock sugar oranges and other leading varieties are mostly eaten fresh. According to statistics from the Provincial Agricultural Commission, in 2017, the province's citrus planting area was 5.7 million mu, with an output of 5.17 million tons, an increase of 130,000 tons over the previous year. The production capacity of citrus has increased, the fresh market has fluctuated, and the processing industry has developed accordingly. According to a survey, a company in Hunan purchases and processes 500,000 tons of citrus annually, and produces more than 50 tons ...
