Abstract

The invention provides a special humic acid controlled-release mixed fertilizer for tobaccos. The fertilizer is prepared from the following components in parts by weight: 182-205 parts of monoammonium phosphate, 217-326 parts of potassium nitrate, 100-200 parts of potassium sulphate, 83-130 parts of ammonium sulfate, 10-20 parts of zinc sulphate heptahydrate, 10-20 parts of borax and 247-252 parts of nitrohumic acid. The special humic acid controlled-release mixed fertilizer for tobaccos provided by the invention can be used for improving the physical and chemical properties of soil, enhancing the immunocompetence of tobacco strains, improving nutrition in the later period and improving the quality of tobaccos and has a very high actual application value and a broad market prospect.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special humic acid blended fertilizer for tobacco. Background technique [0002] Henan is the largest flue-cured tobacco producing area in my country, accounting for nearly 1 / 3 of the country's output. Xuchang Tobacco Fertilizer used cake fertilizer and farmyard manure in the early days. The "Xuchang Tobacco" produced is famous for its high quality and enjoys a certain reputation in the international market. At present, there are obvious problems in Henan tobacco leaves, for example: the color of the middle and lower tobacco leaves is uneven, and the color is not full; the upper tobacco leaves are thicker; The reasons are as follows: First, the long-term predatory use of soil by agricultural production has resulted in the decline of the soil fertility of tobacco planting soil, and the imbalance of some nutrients necessary for tobacco growth; second, the extensi...
