Embodiment

[0039] The method for nitrogen control and quality improvement of flue-cured tobacco in high organic matter tobacco field soil of the present embodiment, its specific steps are as follows:

[0040](1) Tobacco field preparation:

[0041] (1) Tobacco field selection: select rice fields with an organic matter content higher than 45g / kg as tobacco planting fields;

[0042] (2) Returning organic matter to the field: select rice straw with a C / N ratio of 54, chop it into pieces of 5-10 cm, and use it as the organic matter for returning to the field;

[0043] (3) Returning time: 12 days before the tobacco seedlings are planted;

[0044] ⑷. Way of returning to the field: according to the application rate of 4800kg / hm2, the organic matter is evenly sprinkled on the surface of the tobacco planting field, and after softening, it is plowed into the soil, and the plowing depth is 22cm;

[0045] (2), fertilization before planting:

[0046] One day before tobacco seedling planting, accord...

Abstract

The invention discloses a high organic matter tobacco field soil flue-cured tobacco nitrogen controlling and quality improving method, and relates to the technical field of flue-cured tobacco planting. The method particularly comprises the following steps of 1, tobacco planting field preparation, wherein a tobacco field is selected, organic matter returns to the field, time for returning to the field is determined, and a mode of returning to the field is determined; 2, fertilization before planting; 3, tobacco seedling field planting; 4, fertilization after planting; 5, management after planting. The method has the advantages of being capable of enhancing the soil biological activity, controlling the soil nitrogen mineralization capacity, improving the tobacco quality and the like, the method is suitable for planting flue-cured tobacco in a high organic matter tobacco field of a rice-tobacco crop rotation area.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco planting, in particular to a method for nitrogen control and quality improvement of flue-cured tobacco soil in high organic matter tobacco fields. Background technique [0002] Soil is the basis of high-quality tobacco production and the primary environmental factor affecting the quality of flue-cured tobacco. Soil organic matter mainly refers to various animal and plant residues, microorganisms and various organic substances decomposed and synthesized in the soil. For flue-cured tobacco, due to its nitrogen demand law of "less rich, old poor", if the soil organic matter content is too high, the nitrogen release in the late stage of tobacco growth is too high, the upper tobacco leaves are not easy to yellow normally, and even black storms appear. The chemical composition is uncoordinated, the taste is pungent, and the usability is poor, which is extremely unfavorable to the improvement...
