Abstract

The invention discloses compound slow-release fertilizer for improving the yield of rice in a saline and alkaline land. The compound slow-release fertilizer is prepared from the following raw materials in parts by weight: 135 to 145 parts of macro-element fertilizer, 20 to 30 parts of pig offal, 15 to 25 parts of peanut shell powder, 10 to 20 parts of pond sludge, 10 to 20 parts of sawdust, 30 to40 parts of cow dung, 10 to 20 parts of sunflower seed meal, 20 to 30 parts of puffed peanut meal, 5 to 10 parts of a slow-release agent, 2 to 4 parts of basalt powder, 2 to 4 parts of limestone powder and 2 to 4 parts of ammonium molybdate. The slow-release agent is prepared from a network hydrophobic material and zeolite powder. The network hydrophobic material is prepared by adopting the following technology: mixing nano titanium dioxide, oxidized polyethlene wax, an ionic emulsifier, sodium metabisulfite and de-ionized water; under a sealing state, introducing nitrogen gas and increasing the pressure; raising the temperature and stirring; cooling, adding polyethylene glycol and stirring; carrying out ultrasonic treatment; then adding a glutaraldehyde water solution and stirring; cooling, filtering, washing and drying to obtain the network hydrophobic material.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound slow-release fertilizer for improving the yield of rice in saline-alkali land.
