Tobacco cultivation and fertilization method realizing tobacco field improvement and tobacco leaf quality improvement

Abstract

The invention discloses a tobacco cultivation and fertilization method realizing tobacco field improvement and tobacco leaf quality improvement. The tobacco cultivation and fertilization method solvesthe technical problem that the tobacco field soil has a poor physical structure and nutrient imbalance. The method comprises: selecting uniform field pieces with medium soil fertility and flat terrain, preparing soil in the middle and last ten-day of April before the transplanting of the tobacco seedlings, mechanically leveling the tobacco field, carrying out row replacement on biochar, organic bacterial fertilizer and special fertilizer for tobacco, ridging the field through a double ditching method, wherein in ditching, fertilizer is applied to a position under the tobacco ridge, transplanting tobacco seedlings in the last ten-day of April to the first ten-day of May, applying enough water, covering the field with a mulching film, removing the mulching film when the tobacco grows to a rosette stage, carrying out ridging on the tobacco ridge, topdressing tobacco-specific compound fertilizer through a nesting fertilization method, carrying out field management measures and local cultivation technical regulation processes and harvesting mature tobacco leaves according to local regulations. Through reasonable combination of biochar and organic bacterial fertilizer, the soil nutrientbalance and biological properties are improved and the agronomic traits, yield, quality and economic traits of the tobacco are improved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation and fertilization, in particular to a method for tobacco cultivation and fertilization suitable for tobacco areas in central Henan that can take into account the improvement of tobacco fields and the quality of tobacco leaves. Background technique [0002] The main soil types in Henan Tobacco Area are fluvo-aquic soil, cinnamon soil, etc. It is an important production area of ​​Luzhou-flavor flue-cured tobacco in my country. The quality of tobacco planting soil has an important impact on tobacco quality, and the quality of tobacco is related to economic benefits. closely related. [0003] At present, the decline of soil quality in tobacco fields is one of the most important limiting factors restricting tobacco growth, and fertilization is one of the most direct and effective agricultural measures that affect soil physical and chemical properties, soil quality and its sustainable use. At p...
