Abstract

The invention relates to a composite fertilizer special for corn cultivation, and especially relates to a composite fertilizer which is suitable for corn cultivation in Hexi inland irrigated region Gansu province. The composite fertilizer comprises following ingredients, by weight: 40 to 44 portions of urea, 30 to 32 portions of monoammonium phosphate, 16 to 18 portions of potassium sulfate, 2 to 3 portions of zinc sulfate, 1 to 2 portions of ammonium molybdate, 0.3 to 0.5 portion of boric acid and 0.3 to 0.5 portion of industrial citric acid. The formula ratio of the ingredients of the composite fertilizer is specially designed according to existing nutritional conditions of corn field and the nutrient absorption ratio of corn, so that the composite fertilizer is capable of solving a bottleneck problem that the nutrient ratio of corn field is unbalanced, and a problem that pollination of cultivated corn is poor; increasing the solubility of immobilized phosphor in soil; and solving a difficult problem that the availability of phosphor in soil is low. The application of the composite fertilizer is capable of increasing the yield of corn greatly. The invention also relates to a preparation method of the composite fertilizer special for corn.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a special compound fertilizer for producing seed corn; the invention also relates to a preparation method of the above-mentioned special compound fertilizer. Background technique [0002] Relying on its superior corn seed production conditions in the Hexi inland irrigation area of ​​Gansu Province, in the past 10 years, it has attracted DuPont Pioneer, Monsanto, Denghai Pioneer Seed, China Seed, Liaoning Dongya, Beijing Denong, ORG, Dunhuang, etc. More than 90 domestic and foreign seed industry groups have established a corn seed production base of 1.5 million mu, becoming the largest corn seed production base in the country. The corn seed production industry has developed into one of the important pillar industries for increasing farmers' income and increasing agricultural efficiency in Hexi inland irrigation areas one. However, the most prominent prob...
