Embodiment Construction

[0014] 1 The current situation of fertilizer use in production

[0015] Compound fertilizer formula in 2016:

[0016] (1) Tobacco special compound fertilizer complies with GB15063-2009 standard, the ratio of nitrogen, phosphorus and potassium is 8:12:24, nitrate nitrogen / total nitrogen ≥ 35%.

[0017] (2) Potassium sulfate for agriculture conforms to the first-class product standard of GB20406-2006, specific requirements: the appearance is powdery, potassium oxide (K 2 O≥50.0%), chloride ion (Cl≤1.5%), moisture (H 2 O≤1.5%), free acid (H 2 SO 4 ≤1.5%).

[0018] (3) Potassium nitrate total nutrients ≥ 58%, in line with the national standard for first-class agricultural potassium nitrate, N ≥ 13.5%, K 2 O≥44.5%, moisture≤1.2%, Cl≤1.2%, the product quality complies with GB / T20784-2006.

[0019] 2 Addition scheme of trace elements in compound fertilizer

Abstract

The invention discloses a modified compound fertilizer special for tobacco, made by adding, by weight, 0.2-0.7% of magnesium, 0.03-0.04% of boron, 3.5-4.5% of chlorine, and 0.2-0.3% of zinc into compound fertilizer special for tobacco meeting GB15063-2009 or agricultural potassium sulfate meeting GB20406-2006. By applying the modified compound fertilizer special for tobacco in case of shortage of magnesium in soil, it is possible to significantly promote maturing of tobacco and increase the yield and output value of tobacco; by centrally applying the fertilizer in case of rich magnesium in soil, significant inhibition can be provided for maturing of tobacco leaves, especially maturing of upper leaves, and the leaf yield is significantly decreased.

Description

technical field [0001] The invention belongs to the field of agricultural compound fertilizers, and in particular relates to an improved special compound fertilizer for tobacco. Background technique [0002] In traditional agricultural planting, the application of compound fertilizers often only focuses on nitrogen, phosphorus, potassium, etc., and it is easy to ignore the impact of trace elements on soil fertility. Especially for certain types of plants, trace elements tend to have a greater impact on their growth. [0003] The study of soil trace elements is the frontier and basic field of soil science research. Through the study of soil trace elements, the genetic characteristics and parent material characteristics of soil can be revealed, the development degree and fertility level of soil can be revealed, and it can contribute to environmental protection, high-quality production and higher quality. provide the basis for soil improvement.
