The invention relates to a soil conditioner for flue-cured tobacco planting and an application of the soil conditioner. The soil conditioner comprises the following components, by weight percentage, 60-80% of purple soil, 2-5% of humic acid, and 15-38% of magnesium oxide. The soil conditioner can bring abundant soil enzymes and beneficial microorganisms to the soil of a sandy-muddy field, improve the activity of humus, and release the potential base nutrients of the soil. Acidity of the soil in the sandy-muddy field and the ratio of the mineral content in the soil are adjusted. The soil conditioner can promote effective absorption of magnesium in the soil during a growth process of flue-cured tobacco, improve the yield and quality of tobacco leaves, and improve the economical benefit of flue-cured tobacco planting.
Description
technical field [0001] The invention relates to the field of soil conditioners, in particular to a soil conditioner suitable for planting flue-cured tobacco and its application. Background technique [0002] High-quality soil is the basis for high-quality flue-cured tobacco production. Sand and mud field soil is one of the most important soils for tobacco planting in southern tobacco areas. In recent years, due to long-term continuous cropping and continuous application of a large amount of chemical fertilizers such as nitrogen, phosphorus, and potassium, the soil environment and soil quality of the southern smoke-planting sandy mud fields have deteriorated, resulting in a lack or imbalance of nutrients in the soil (expressed as a large amount of nitrogen, phosphorus, etc. Excess elements, insufficient magnesium content and medium and trace element content, low humic substance activity). The deteriorating soil environment is not conducive to the normal growth of tobacco pl...
