Special organic fertilizer formula for lettuce

Abstract

The invention discloses a special organic fertilizer formula for lettuce, and belongs to the technical field of fertilizer formulas, and aims to solve the problem that an existing chemical fertilizeris not rich in nutrient elements. The special organic fertilizer is prepared from the following raw materials in parts by weight: 5-10 parts of distillers' grains, 10-20 parts of human excreta, 3-5 parts of chicken manure, 10-20 parts of bone meal, 20-30 parts of wheat bran, 2-7 parts of bacillus subtilis, 1-5 parts of pseudomonas aeruginosa, 1-5 parts of field snails, 3-15 parts of urea and 5-8 parts of polyacrylamide. The special organic fertilizer formula is suitable for fertilizers.

Description

technical field [0001] The invention belongs to the technical field of fertilizer formula, in particular to a special organic fertilizer formula for lettuce. Background technique [0002] my country is a large agricultural country with a large rural planting area. Fertilization is a very critical link in the process of artificial planting. At present, most of the fertilizers used for crops rely on inorganic chemical fertilizers as base fertilizers and topdressing fertilizers, resulting in the reduction of soil organic matter and the decline in fertilizer and water retention performance. Nutrients in the soil permeate and lose a large amount, are fixed or volatilized, heavy metal elements accumulate beyond the standard, and chemical pesticides for pest control and disease treatment cannot be degraded, resulting in excessive pesticide residues. The agricultural products grown in the above situations not only directly threaten the health of consumers, but also the soil environmen...
