Abstract

A simplified efficient fertilizer specially used for corn and suitable for saline-alkali land and a manufacturing process thereof are disclosed. The fertilizer comprises, by weight, 25-30% of N, 8-12% of P2O5, 4-8% of K2O, 1-4% of humic acid, 0.2-0.5% of Zn, 0.4-0.8% of Ca and 0.4-1.0% of a nitrification inhibitor. The method and the process are advantageous in that 1) added functional factors comprising the humic acid and calcium superphosphate are acidic and can improve soil alkalinity, and calcium ions of the calcium superphosphate can exchange sodium ions in soil so as to obviously reduce soil salinity, 2) urea-formaldehyde added in a granulation step can obviously improve the granulation rate and granular strength of the fertilizer, thus overcoming a later fertilizer granule efflorescence problem, slow-release nitrogen in the urea-formaldehyde and quickly available nitrogen in urea are combined, thus meeting a corn growth absorption curve and avoiding later nitrogen deficiency for corn, and addition of the nitrification inhibitor reduces nitrogen loss and increases the nutrient utilization rate, and 3) an anti-blocking agent used in the fertilizer is synthesized through saponification, is low in cost, adopts waste grease, is green and meets the strategy of sustainable development.

Description

technical field [0001] The invention relates to a lightweight and simplified special high-efficiency fertilizer for corn suitable for use in saline-alkali land and a manufacturing process thereof, belonging to the technical field of soil improvement and high-efficiency fertilization. Background technique [0002] There are more than 99 million hectares of saline-alkali land in my country, of which about 6 million hectares of saline-alkali arable land seriously restricts the development of agriculture in my country. How to develop low-yield saline-alkali land and saline-alkali wasteland is an important issue in the development of modern agriculture. Saline-alkali soil has high salinity and contains excessive The soluble salts in the soil will increase the osmotic pressure of the soil solution, which will cause the physiological dryness of plants, which is not conducive to the growth and development of crops. At the same time, saline-alkali land also has the general characteris...
