Abstract

The invention relates to a water soluble fertilizer for agricultural production, in particular to an acidic drip irrigation fertilizer which is suitable for calcareous soil and applied to processing tomatoes, and a preparation method thereof. The acidic drip irrigation fertilizer for the processing tomatoes mainly comprises the following raw materials in parts by weight: 18-21 parts of ammonium sulphate, 33-38 parts of urea phosphate, and 42-48 parts of potassium nitrate. The preparation method of the acidic drip irrigation fertilizer for the processing tomatoes comprises the steps of: separately crushing the raw materials such as the ammonium sulphate, the urea phosphate and the potassium nitrate in parts by weight, and screening the crushed materials, wherein the screening mesh number is 40-50 meshes; and uniformly mixing the screened materials, performing secondary crushing on the uniformly mixed materials, and performing secondary screening, wherein the mesh number of the secondary screening is 70-80 meshes. The acidic drip irrigation fertilizer for the processing tomatoes is convenient and practical, the production cost can be reduced, the acidic drip irrigation fertilizer is suitable for the calcareous soil, soil is partially acidified under drip irrigation conditions, plugging of an irrigation system is avoided, and the yield of the processed tomatoes is increased; in addition, the preparation method is simple in preparation and is economical and practical.

Description

technical field [0001] The invention relates to a water-soluble fertilizer in agricultural production, in particular to an acidic drip irrigation fertilizer suitable for calcareous soil and aimed at processing tomatoes and a preparation method thereof. Background technique [0002] Calcareous soils contain high levels of free calcium carbonate (CaCO 3 Content 5% ~ 30%), so the soil is alkaline (pH = 7.5 ~ 8.5), and has a strong buffer. Although calcareous soil has a high calcium content, calcium deficiency is not uncommon in processing tomato planting in Xinjiang and other places. Studies suggest that calcium deficiency is not caused by low calcium content in the soil, but is related to the physical and chemical properties of the soil and the existing forms of Ca in the soil. The calcium content and availability in the soil are affected by the pH value of the environment. Although the total calcium content in calcareous soil is very high, the water-soluble calcium that can ...
