Embodiment

[0029] The 3D three-dimensional fertilization method of flue-cured tobacco base fertilizer comprises the following steps:

[0030] (1) Ridging: 15 days to 30 days before transplanting tobacco (cured tobacco varieties are NC55, NC102), compound fertilizer (N:P 2 o 5 :K 2 O=10:10:20), potassium sulfate, organic fertilizer mixed, uniformly applied to the soil, then mixed with the fertilizer and soil, and then ridged to make the fertilizer evenly distributed in the ridge body; the amount of fertilizer applied is: Medium-fertility tobacco fields apply 40-45 kg of compound fertilizer per mu, more than 10 kg of potassium sulfate, and 30-40 kg of organic fertilizer.

[0031] The organic fertilizer is made of the following raw materials in weight percentage: 50% of human and livestock manure (cow manure, pig manure, human manure, sheep manure 1:1:1:1), 40% of wheat straw, and 10% of garlic straw.

[0032] The preparation method is:

[0033] Weigh the raw materials according to the ...

Abstract

The invention discloses a 3D fertilization method for a base fertilizer used for flue-cured tobacco, belonging to the technical field of agriculture. The 3D fertilization method mainly comprises the following steps: in 15 to 30 d before transplantation of flue-cured tobacco, mixing composite fertilizer, potassium sulfate and organic fertilizer, uniformly applying the obtained mixture into soil, then mixing the fertilizer with soil and carrying out ridging so as to allow the fertilizer to be uniformly distributed in ridge bodies. The method mitigates the phenomenon of seedling burnt caused by concentrated fertilization, abates the phenomena of weak growth vigor of flue-cured tobacco in an early growth stage and flue-cured tobacco with unnatural elimination of jaundice, too thick upper tobacco leaves and too great nitrogen content in tobacco leaves, improves the utilization rate of the fertilizer, avoids resource waste and environmental pollution caused by concentrated fertilization, enhances appearance and inherent quality of the tobacco leaf, increases the proportion of first-class tobacco and has obvious economic benefits.

Description

technical field [0001] The invention discloses a base fertilizer fertilization method for tobacco planting, in particular a 3D three-dimensional fertilization method for flue-cured tobacco base fertilizer, and belongs to the field of agricultural technology. Background technique [0002] In recent years, it has been found that the growth of flue-cured tobacco is weak in the early stage of growth, but in the late stage of vigorous growth, black storms, excessively thick upper leaves, and high nitrogen content on the leaf surface appear. After investigation and analysis, this phenomenon is related to the location of the base fertilizer. At present, the fertilization methods of base fertilizer in flue-cured tobacco cultivation include central strip application, nest application, double-side strip application, and single-side strip application. Double-side strip application is currently the main fertilization method for flue-cured tobacco production. There are problems such as t...
