Abstract

The invention discloses a calcium-magnesium compound fertilizer, and a preparation method and an application method thereof. The calcium-magnesium compound fertilizer is prepared from calcium chloride, anhydrous magnesium sulfate, citric acid, sodium citrate and ethylene diamine tetraacetic acid (EDTA-2Na) serving as raw materials according to a certain proportion. In the invention, calcium and magnesium in a chemical fertilizer are mixed scientifically; and after fertilizing, the nutrition requirements of flowers, stems and fruits of crops can be met by using calcium and magnesium fertilizers, the nutrition requirements of crops are met, the storage period of fruits can be prolonged, picking time can be prolonged, the yield of pulse crops is increased, and the quality of pulse crops is improved.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to a calcium-magnesium compound fertilizer, a preparation method and an application method thereof. Background technique [0002] At present, the fertilizers in the prior art include urea, potassium fertilizer, and phosphorus fertilizer, etc. These fertilizers have a certain growth-promoting effect on crops, but there are some problems in these fertilizers, such as imbalanced nutrient ratios, which cannot meet the needs of plant nutrients Also some fertilizers have poor improvement to soil, especially saline-alkali soil. After using the fertilizers of the prior art, the soil quality deteriorates, which is unfavorable for the improvement of the output and quality of crops. Especially for bean crops with rhizobia, there is a lack of high-quality fertilizers, and the supplementation of calcium and magnesium fertilizers has not been given enough attention. The lack of c...
