Problems solved by technology

[0004] In order to ensure the quality of tobacco, for a long time the industry has formed a technical model of applying less nitrogen fertilizer, not applying organic fertilizer or carefully applying a small amount of organic fertilizer, and not paying attention to the prevention and control of heavy cropping obstacles, resulting in a relatively low level of tobacco fertilization, root rot, black stem Diseases, viral diseases, leaf spot diseases and other diseases are serious, the yield and quality are low, and the economic benefits cannot be guaranteed

Embodiment 1

[0027] A high-quality and high-yield fertilization method for tobacco cropping planting, transplanting 1300 tobacco trees per mu, comprising the following steps:

[0028] (1) When preparing the ground, apply 40 kg each of high-concentration balanced humic acid complex organic-inorganic compound fertilizer and humic acid trace element organic fertilizer per mu. The two can be mixed evenly and applied together, or applied separately (in no particular order) plowing the land afterwards;

[0029] (2) When forming a ridge, apply 12 kg of potassium nitrate and 30 kg of high-concentration, high-potassium humic acid complex organic-inorganic compound fertilizer at the bottom of the double ditch. The two can be mixed evenly and applied together, or applied separately (without Specific order) and mix with soil;

[0030] (3) When transplanting, apply 6 kg of nitrosulfur-based high-nitrogen fertilizer and 6 kg of high-humic acid zinc-boron trace element organic fertilizer in the hole, mi...

Embodiment 2

[0046] A high-quality and high-yield fertilization method for tobacco cropping planting, transplanting 1300 tobacco trees per mu, comprising the following steps:

[0047] (1) When preparing the ground, apply 30 kg each of medium-concentration balanced humic acid complex organic-inorganic compound fertilizer and humic acid trace element organic fertilizer per mu. The two can be mixed evenly and applied together, or applied separately (in no particular order) plowing the land afterwards;

[0048](2) When forming a ridge, apply 10 kg of potassium nitrate and 25 kg of high-concentration, high-potassium humic acid complex organic-inorganic compound fertilizer at the bottom of the double ditch. The two can be mixed evenly and applied together, or applied separately (without Specific order) and mix with soil;

[0049] (3) When transplanting, apply 5 kg each of nitrosulfur-based high-nitrogen fertilizer and high-humic acid zinc-boron trace element organic fertilizer in the hole. Mix ...

Abstract

The invention discloses a high quality and high yield fertilizer application method for repeated planting of tobacco. The method includes the steps of 1), during land preparation, applying 30-40kg ofhigh concentration balanced humic acid complex organic-inorganic compound fertilizer and 30-40kg of humic acid trace element organic fertilizer per mu; 2), during ridging, applying 10-12kg of potassium nitrate to double trench bottom per mu and 25-30kg of high concentration and high potassium humic acid complex organic-inorganic compound fertilizer; 3), during hole application, applying 5-6kg of nitrate and sulfur based high nitrogen fertilizer and 5-6kg of high humic acid zinc boron trace element organic fertilizer per mu. With the method, the utilization rate of fertilizer nutrients can be improved, stress resistance of crops is improved, the occurrence of various stubble diseases are reduced, the yield of tobacco leaves is increased, and quality of the tobacco leaves is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a high-quality and high-yield fertilization method for repeated tobacco planting. Background technique [0002] Tobacco is a special economic crop. Its quality is more affected by fertilization than ordinary crops. Tobacco likes potassium, avoids chlorine and avoids heavy cropping, is sensitive to zinc, likes zinc and boron, and has strict requirements on nitrogen fertilizer. In tobacco fertilization, it is necessary to ensure that the tobacco plants have a good root system and robust growth conditions. It is necessary to ensure that a relatively large biomass is obtained in the middle and early stages, and it is also necessary to ensure that nitrogen fertilizer is not excessive at the end of the vigorous growth period, otherwise it will affect yellowing and reduce quality. [0003] Continuous cropping, also known as continuous cropping, refers to the continuous planting...
