Fertilizing method for tobacco

Abstract

The invention relates to a fertilizing method for tobacco. The method comprises a first step of selecting biogas slurry and biogas residue with normal gas production 2 or more months; a second step of soaking seeds with the biogas slurry: immersing the seeds for 8-10 hours; a third step of fertilizing in a tobacco seedling bed: the third step comprises two procedures of fertilizing a base fertilizer in the tobacco seedling bed by applying the biogas residue, diammonium phosphate, potassium chloride and poly(aspartic acid) in combination with plough before reorganizing the bed; and fertilizing an additional fertilizer in the tobacco seedling bed in two stages, wherein a first stage is spraying a ammonium sulfate solution before a three-leaf stage; and a second stage is applying the biogas slurry and watering in time after topdressing one day before the tobacco seedlings are taken out from the tobacco seedling bed; and a fourth step of fertilizing in a big field: the fourth step comprises two procedures of fertilizing a base fertilizer in the big field by applying the biogas residue and diammonium phosphate as the base fertilizer, and simultaneously mixing the poly(aspartic acid) into the base fertilizer three days before transplanting; and fertilizing an additional fertilizer in the big field, wherein the fertilizing process is carried out in two times, specifically, the first time is performed in 10 days after the transplanting, and at the same time, and a mixed solution of the biogas slurry and poly(aspartic acid) are sprayed on leaf surfaces simultaneously; and the second time is performed in 20 days after the transplanting, and potassium sulphate is applied.

Description

technical field [0001] The invention relates to a tobacco cultivation method, in particular to a tobacco fertilization method. Background technique [0002] Tobacco is one of the important economic crops in my country, which has contributed to increasing the country’s financial accumulation and satisfying market consumption. Tobacco requires a variety of nutrients and consumes a lot of fertilizer. Long-term single application of chemical fertilizers will cause soil compaction and nutrient imbalance , poor physical properties and other long-term problems, the production capacity has dropped significantly, and the fertilizer efficiency of organic fertilizers is slow. At the same time, in recent years, biogas construction has developed rapidly, which has produced good economic and social benefits, but biogas waste cannot be digested and utilized in time. , It will also affect the normal operation and circulation of the biogas digester. Biogas slurry and biogas residue not only h...
