Embodiment 1

[0040] The test group is a special fertilizer for tobacco fields that can reduce the application and increase the efficiency and is applied at one time. The types of fertilizers are: 80 parts of tobacco ternary compound fertilizer, 20 parts of diammonium phosphate, 36 parts of potassium sulfate, 20 parts of potassium nitrate, 20 parts of magnesium sulfate, diphosphate 2 parts of potassium hydrogen, 2 parts of borax, 70 parts of rapeseed cake fertilizer. Weigh each component raw material according to the formula ratio, and fully stir and mix each component raw material. The fertilizer application rate is 125kg / mu, including 90kg / mu of chemical fertilizer and 35kg / mu of organic fertilizer (rapeseed cake fertilizer). The specific fertilization method is: when the tobacco field is prepared and ridged, apply the fertilizer in one-time section, the fertilization section is 25cm, and the interval is 25cm, then use mechanical ditching and ridges on both sides of the fertilizer to make...

Embodiment 2

[0045] The test group is a special fertilizer for tobacco fields that can be reduced and increased and applied at one time. The types of fertilizers are: 90 parts of tobacco ternary compound fertilizer, 20 parts of diammonium phosphate, 35 parts of potassium sulfate, 25 parts of potassium nitrate, 24 parts of magnesium sulfate, diphosphate 3 parts of potassium hydrogen, 3 parts of borax, 80 parts of rapeseed cake fertilizer. Weigh each component raw material according to the formula ratio, and fully stir and mix each component raw material. The fertilizer application rate is 126kg / mu, including 90kg of chemical fertilizer and 36kg of organic fertilizer (rapeseed cake fertilizer). The specific fertilization method is: when the tobacco field is prepared and ridged, apply the fertilizer in one-time section, the fertilization section is 25cm, and the interval is 25cm, then use mechanical ditching and ridges on both sides of the fertilizer to make the fertilizer applied in sections...

Embodiment 3

[0050] The test group is a special fertilizer for tobacco fields that can reduce the application and increase the efficiency and is applied at one time. The types of fertilizers are: 70 parts of tobacco ternary compound fertilizer, 15 parts of diammonium phosphate, 30 parts of potassium sulfate, 15 parts of potassium nitrate, 18 parts of magnesium sulfate, diphosphate 1 part of potassium hydrogen, 1 part of borax, 60 parts of rapeseed cake fertilizer. Weigh each component raw material according to the formula ratio, and fully stir and mix each component raw material. The fertilizer application rate is 115.5kg / mu, including 82.5kg of chemical fertilizer and 33kg of organic fertilizer (rapeseed cake fertilizer). The specific fertilization method is: when the tobacco field is prepared and ridged, apply the fertilizer in one-time section, the fertilization section is 25cm, and the interval is 25cm, then use mechanical ditching and ridges on both sides of the fertilizer to make the...

Abstract

Aiming at the problems of long-term and large-amount chemical fertilizer application, serious loss of fertilizer nutrients and low utilization rate in a tobacco-rice rotation area, the invention provides fertilizer special for a tobacco field and an application reducing and effect increasing disposable application method thereof. The fertilizer special for the tobacco field is prepared from the following raw materials in parts by weight: 70 to 90 parts of tobacco ternary compound fertilizer, 15 to 25 parts of diammonium phosphate, 30 to 40 parts of potassium sulfate, 15 to 25 parts of potassium nitrate, 18 to 24 parts of magnesium sulfate, 1 to 3 parts of monopotassium phosphate, 1 to 3 parts of borax and 60 to 80 parts of rapeseed cake fertilizer. The fertilizer provided by the inventionis reasonable in component matching, and nutrients required for flue-cured tobacco can be coordinated; through once application, heavy demands on nutrients during an earlier stage and a middle stage of the flue-cured tobacco can be met through sustainable supply of higher-concentration fertilizer nutrients during an early-middle stage, a fertilizer requirement law for growth and development of a tobacco plant can be adapted, and the purposes of increment of tobacco leaf quality and application reducing and effect increasing of chemical fertilizer can be realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilization, and in particular relates to a special fertilizer for tobacco fields and a one-time application method thereof with reduced application and increased efficiency. Background technique [0002] Due to the shortage of cultivated land resources in my country and the excessive utilization intensity, due to unreasonable construction land occupation and long-term large-scale application of chemical fertilizers, not only the number of cultivated land has been greatly reduced, but also the quality of cultivated land has continued to decline in general. At present, the central government attaches great importance to the protection of cultivated land quality. In 2015, the Central Document No. 1 proposed to "continuously enhance the grain production capacity and implement actions to protect and improve the quality of cultivated land". In order to reduce the use of chemical fertilizers, imp...
