Abstract

The invention discloses a compound fertilizer for cowpeas planted in a saline-alkali land and a manufacturing method of the compound fertilizer. The compound fertilizer is characterized by comprising the following components, by weight, 40-50 parts of a filter residue of an enzymic preparation, 20-30 parts of seaweed powder, 1.2-1.4 parts of a bacterial preparation, 7-9 parts of urea, 4-6 parts of calcium superphosphate, 4-6 parts of potassium chloride, 0.06-0.08 part of a readily-available regulator, 3-4 parts of an iron-microelement-containing fertilizer, 8-10 parts of a soil conditioner, 0.3-0.5 part of sodium metasilicate, and 4-5 parts of potassium humate. A fermented product contains microorganic mycelia, plant proteins, amino acids, vitamins, and microelements, which are beneficial for supplementing nutrient substances required by cowpea production. The seaweed powder regulates alkaline ions in soil; functional substances, such as phosphorus and potassium decomposing agents and the soil conditioner, are added to prevent soil acidification and improve the soil structure; the fertilizer has balanced nutrition; and the iron-microelement-containing fertilizer can increase the adsorption rate and conversion rate of iron in cowpeas, improve health-care value of cowpeas, and enable production increase and yield increase to be realized.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a compound fertilizer for cowpea planting in saline-alkali land and a preparation method thereof. Background technique [0002] The salt content in saline soil exceeds 0.3%, which will easily lead to soil compaction and decrease in fertility, which is not conducive to crops absorbing nutrients and hindering crop growth. The soluble salts of saline soil mainly include sodium, potassium, calcium, magnesium and other sulfates, chlorides, carbonates and bicarbonates. Sulfates and chlorides are generally neutral salts, and carbonates and bicarbonates are alkaline salts. As soil salinization is becoming more and more serious, the demand for acid-alkaline soil conditioners is increasing. How to reduce the salinity and alkalinity in the soil and adjust the salinity level of the soil is an urgent problem to be solved in the industry. [0003] At present, some potassium bisu...
