High-potash fertilizer special for tobaccos

Abstract

The invention relates to a high-potash fertilizer special for tobaccos, comprising the following ingredients in percentage by weight: 35-63 percent of humus organic carriers, 35-60 percent of potassium sulphate, and 2-8 percent of polyacrylamide and / or super absorbent resin. The high-potash fertilizer special for tobaccos has the advantages of improving the potassium content of tobacco leaves, increasing soil organic matters, improving the nutrient availability in the soil, promoting the root system growth of tobacco plants, evidently enhancing the potassium content of the tobacco leaves, improving the quality of the flue-cured tobacco leaves and increasing the aroma content; the application of the high-potash fertilizer special for tobaccos can reduce dependence on normal potash fertilizer or improve the use efficiency of the normal potash fertilizer. Applying the high-potash fertilizer special for tobaccos as a base fertilizer at the use level of 30-50 kg / 667 m<2> for one time can satisfy the potassium absorption requirements in the entire growing period of the tobacco leaves without applying the additional potash fertilizer in later period, thereby saving time and labor.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special high-potassium fertilizer for tobacco. Background technique [0002] Tobacco is one of the most widely grown commercial crops in the world. The economic benefit of tobacco production depends not only on the yield and production cost of tobacco leaves, but also on the quality of tobacco leaves. Therefore, what tobacco pursues is "high quality and suitable production", not high yield. Potassium content in tobacco leaves is one of the important indicators to measure the quality of tobacco leaves. Potassium is one of the most important tobacco leaf quality elements, which not only has a significant effect on the flammability of tobacco, but also is related to the taste of tobacco leaves and the safety of cigarette products. Tobacco is a typical potassium-loving crop and requires a large amount of potassium. According to research in North Carolina, the United States, tobacco absorbs potass...

AI Technical Summary

Problems solved by technology

For example, 1:1 type clay minerals (kaolinite, etc.) have a weak ability to absorb potassium and cannot fix potassium or the amount of fixed potassium is very small; while illite of 2:1 type clay minerals has a certain ability to fix potassium , which reduces the effectiveness of potassium fertilizer applied to the soil, and cannot meet the demand for potassium fertilizer for the growth and development of tobacco plants
