Balanced water-soluble fertilizer with wide applicability as well as preparation method and application of balanced water-soluble fertilizer

Abstract

The invention belongs to the technical field of water-soluble fertilizers, and particularly relates to a balanced water-soluble fertilizer with wide applicability as well as a preparation method and application thereof. The balanced water-soluble fertilizer is prepared from the following raw material components in parts 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, 65 to 70 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 emulsifier, 5 to 11 parts of scale remover and 1 to 2 parts of synergist. The balanced water-soluble fertilizer does not flocculate or crystallize and separate out at low temperature after being placed for a long time, and the utilization efficiency of the fertilizer is improved. The balanced water-soluble fertilizer has the advantages of being simple in preparation process, low in raw material cost and suitable for rapid and large-scale production, is used for topdressing of crops in the whole growth period, can achieve the effects of increasing production and income, improving the quality of agricultural products and balancing soil nutrients, avoids fertilizer waste and reduces soil pollution.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizers, and in particular relates to a balanced water-soluble fertilizer with wide applicability, a preparation method and an application. 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 of citrus processin...
