Embodiment 1

[0031] First prepare the fertilizer slow-release bag, specifically choose kraft paper with a length of 15cm and a width of 20cm, fold the kraft paper equidistantly along the wide side to form a bag with a length of 15cm and a width of 10cm, and finally use an edge banding machine to seal the long side of the bag and a Side brim. On the surface of both sides of the prepared bag, 9 rows of micro-holes with a diameter of 0.5 mm are drilled with a tool, and the row spacing is 10 mm; wherein, the spacing between each row of adjacent micro-holes is 2 mm.

[0032] Then weigh 9.13g of urea, 11.66g of potassium dihydrogen phosphate, 21.54g of potassium nitrate, 12.26g of potassium sulfate, 0.88g of sucrose, and 0.25g of carbofuran, and mix them uniformly; The fertilizer slow-release bag, and finally seal the edge, and then the finished product is made.

[0033] When in use, make a nest on the flue-cured tobacco planting ridge with a spacing of 110 cm in advance. Specifically, make a r...

Abstract

The invention discloses a flue-cured tobacco slow release fertilizer and an application method thereof and solves problems that slow/controlled release fertilizers in prior art are high in production cost and complicated in technological process and membrane materials remained in the soil after fertilizer nutrients are released cause secondary pollution on soil environments. The the flue-cured tobacco slow release fertilizer is mainly composed of following components of, by weight, 8.48-9.78g of urea, 10.58-12.50g of monopotassium phosphate, 20.00-23.08g of potassium nitrate, 12.40-14.26g of potassium sulphate, 0.52-1.10g of cane sugar and 0.20-0.30g of carbofuran. According to the flue-cured tobacco slow release fertilizer and the application method thereof, the number of fertilizer applying can be reduced, labor intensity for applying the fertilizer is reduced, utilization efficiencies of the fertilizer are improved, environmental pollution is reduced and the flue-cured tobacco slow release fertilizer is low in production cost, simple in process, convenient to use and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of novel fertilizers, and in particular relates to a slow-release fertilizer for flue-cured tobacco and an application method thereof. Background technique [0002] Fertilization is one of the important agronomic measures in flue-cured tobacco production. At present, the common nitrogen, phosphorus and potassium fertilizers used in the production of flue-cured tobacco are all granular or powdery. This type of fertilizer is easily dissolved in water. Cause the pollution of surface water system or groundwater; on the other hand, reduce the utilization efficiency of fertilizer. In the production of flue-cured tobacco, the general base fertilizer mainly includes oil dry, tobacco special fertilizer compound fertilizer, potassium sulfate, potassium nitrate, etc.; after transplanting flue-cured tobacco for 7-15 days, it is often necessary to topdress potassium nitrate fertilizer 1-2 times to raise seedlings; Afte...
