Cucumber medical fertilizer and preparation method thereof

Abstract

The invention relates to cucumber medical fertilizer. The cucumber medical fertilizer comprises the following raw materials in parts by weight: 32.3 to 33 parts of potassium sulphate, 21.2 to 22 partsof monoammonium phosphate, 19.3 to 20 parts of urea, 17.8 to 18.6 parts of furfural residue, 1.98 to 2.3 parts of polyvinyl alcohol, 1.94 to 2.1 parts of sodium polyacrylate, and 1.92 to 2 parts of cupric acetate. The cucumber medical fertilizer has the advantages that the formula ratio of all components in the fertilizer is screened according to plentiful-lack indexes of nitrogen, phosphorus andpotassium in Hexi Corridor of Gansu Province and the absorption ratio to nitrogen, phosphorus and potassium by cucumber, and the problems that alien species in cucumber pots in Hexi Corridor of GansuProvince are increased, the organic content is low, the nitrogen, phosphorus and potassium nutrition ratio is out-of-balance, nitrate exceeds standards, and the traditional special fertilizer does not contain organic matter, and does not have disease resistance, water retention and soil amelioration efficacies. The invention further relates to a preparation method of the cucumber multifunctionalspecial fertilizer.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a medicinal fertilizer for cucumbers. Background technique [0002] The cucumber industry in the solar greenhouse of the Hexi Corridor in Gansu Province has become one of the important pillar industries for increasing agricultural efficiency and farmers’ income. The growing area dominated by Jiuquan City has the following major problems: 1. Large cucumber planting area, long continuous cropping years, increased soil harmful organisms, and unbalanced ratio of nitrogen, phosphorus and potassium nutrients; Salt exceeds the standard; 3. The ratio of nitrogen and phosphorus input of chemical fertilizers to organic fertilizer nitrogen and phosphorus input is 1:0.28, resulting in a decrease in soil organic matter content and a weakened soil water storage function; 4. Traditional compound fertilizers sold on the market do not contain organic matter. It does not...

[0002] The cucumber industry in the solar greenhouse of the Hexi Corridor in Gansu Province has become one of the important pillar industries for increasing agricultural efficiency and farmers’ income. The growing area dominated by Jiuquan City has the following major problems: 1. Large cucumber planting area, long continuous cropping years, increased soil harmful organisms, and unbalanced ratio of nitrogen, phosphorus and potassium nutrients; Salt exceeds the standard; 3. The ratio of nitrogen and phosphorus input of chemical fertilizers to organic fertilizer nitrogen and phosphorus input is 1:0.28, resulting in a decrease in soil organic matter content and a weakened soil water storage function; 4. Traditional compound fertilizers sold on the market do not contain organic matter. It does not have the effect of water retention, which affects the sustainable development of the cucumber industry in this area
