Problems solved by technology

[0003] However, the existing cultivation technology has the following problems: because the variety is sensitive to nitrogen fertilizer, excessive individual growth and poor population structure often occur in production practice due to improper site selection, large nitrogen application rate, unreasonable topping and leaf retention, etc. The problem caused the field to fail to mature and fall yellow in real time, which seriously affected the output value of this variety.

Embodiment 1

[0018] A cultivation method of Yuyan No. 7 flue-cured tobacco variety, specifically comprising the following steps.

[0019] 1. Field selection: Select low-to-medium fertility fields or flue-cured tobacco fields that have been cropped continuously for more than 2 years. The soil alkaline nitrogen content is less than 60 mg / kg. Avoid crops with high nitrogen residues such as corn, peanuts, and vegetables, and homologous diseases Previous stubble plots.

[0020] 2. Fertilization technology: It mainly includes four links: determination of fertilization amount, strip fertilizer application, hole fertilizer application and top dressing application;

[0021] (1) Determination of fertilization amount: Determine the fertilization amount according to the basic soil fertility of the tobacco planting field. The nitrogen application rate of low-fertility fields is 4.5-4.8 catties / mu; the nitrogen application rate of medium-fertility fields is 2.8-3.0 catties / mu;

[0022] Low-fertility f...

Abstract

The invention relates to a Henan tobacco number 7 flue-cured tobacco variety cultivation method includes land selection, fertilization, planting, and topping and leaf retaining. A poor and middle-fertility farm land is selected, wherein the soil alkali-hydrolyzable nitrogen content of the poor and middle-fertility farm land is less than 60 mg / Kg; the nitrogen application amount of the middle-fertility farm land is 2.8-3.0 jin / mu, and the nitrogen application amount of the poor fertility farm land is 4.5-4.8 jin / mu. The cultivation method can control individual development level, coordinate a group structure, and improve the maturity and the quality of tobacco leaves.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf cultivation, and in particular relates to a cultivation method of Yuyan No. 7 flue-cured tobacco variety. Background technique [0002] Reasonable population structure and individual development are the key to the formation of high-quality tobacco leaves. Appropriate nitrogen application rate, timely topping, and reasonable leaf retention have important effects on the field population structure and individual development of flue-cured tobacco. Yuyan No. 7 is a strong-flavored characteristic flue-cured tobacco variety bred by the Tobacco Research Institute of Henan Academy of Agricultural Sciences. It has strong local characteristics, orange color, good aroma, sufficient aroma, and high potassium content in tobacco leaves. [0003] However, the existing cultivation technology has the following problems: because the variety is sensitive to nitrogen fertilizer, excessive individual growth and po...
