Abstract

The invention discloses a ureaformaldehyde fertilizer for lettuce, a preparation method, and a planting method of the lettuce. The ureaformaldehyde fertilizer for the lettuce is prepared from the following raw materials in parts by weight: 5 to 6 parts of orange peel, 2 to 3 parts of sodium borate, 90 to 100 parts of urea, 53 to 60 parts of formaldehyde, 20 to 30 parts of zinc sulfate, 2 to 3 parts of corn prolamine, 18 to 20 parts of kerogen shale ash, 6 to 7 parts of monopotassium phosphate, 3 to 4 parts of soybean curb residue, 0.6 to 1 part of polyglycerol fatty acid ester, 0.7 to 1 partof sophocarpidine, 3 to 4 parts of oxalic acid, 1 to 2 parts of dipotassium glycyrrhizinate, and 1 to 2 parts of ferrous chloride. The fertilizer provided by the invention is low in production cost, high in nutrient content, easy to compound, capable of being absorbed by crops, convenient in formula fertilization and mechanical fertilization, convenient to apply, capable of being absorbed by the crops directly, and beneficial to reducing manpower expense and material resource consumption.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a urea-formaldehyde fertilizer for lettuce, a preparation method and a planting method of lettuce.
