Embodiment

[0031] The inventor carried out field experiments for three consecutive years (2011-2013) in Junzhou Famous Sun-cured Tobacco Science and Technology Demonstration Park in Junzhou, Hubei Province (Location: Group 3, Wulongchi Village, Xijia Town, Danjiangkou City). The tobacco leaves produced by the cultivation method are compared, and the indicators such as economic benefit, appearance quality, chemical composition, and sensory evaluation quality are analyzed together with the tobacco leaves of the present invention, and the feasibility of the high-yield and high-quality cultivation method of the present invention is obtained, as follows:

[0032] 1. The first crop of tobacco cultivation:

[0033] (1) Planting layout: First, the selected tobacco planting area must be below 350 m above sea level. After analyzing the meteorological conditions of the famous sun-cured tobacco production area in Junzhou, Shiyan City, it is concluded that the tobacco planting area at this altitude i...

Abstract

The invention provides a culturing method of sun-cured tobacco. The method comprises the steps of measures of optimizing a planting configuration, brining forward seedling nursing time and a transplanting period and the like, promoting a first harvest of tobacco to early grow and fast develop, harvesting at proper mature time, and providing sufficient growth period for the second harvest of tobacco; by using the eugonic advantage of axillary buds after the Junzhou sun-cured tobacco are pinched, selecting and remaining the axillary buds close to the ground to culture the second harvest of tobacco, thus improving the use rate and yield of unit area land, and increasing the tobacco leaf yield. By using the advantage that the tobacco leaves harvested by two times in one year are doubly increased, three leaves at the upper and lower parts with poorer quality are abandoned, the ratio of the first-class tobacco and medium tobacco is improved, the aim of optimizing the tobacco leaf structure and improving the tobacco leaf quality is achieved, and the tobacco economic benefits of tobacco farmers are increased.

Description

technical field [0001] The invention relates to a method for cultivating tobacco, in particular to a method for cultivating sun-cured tobacco. Background technique [0002] Junzhou famous sun-cured tobacco belongs to a kind of endemic light-colored sun-cured yellow tobacco, which is mainly distributed in Danjiangkou City, Yunxi County, and Yunxian County in the Han River Basin. Affected by local climate conditions and cultivation techniques, only one crop of Sun-cured Tobacco in Junzhou can be planted a year. The land is idle from October to February of the next year, and other crops cannot be planted. The land utilization rate and output rate per unit area vary. high. A tobacco plant has limited leaves. In order to ensure the yield, more leaves are kept in production, and the lower leaves and upper leaves with poor quality are rarely discarded. This cultivation method produces about 40% of the upper leaves and 35% of the middle leaves. About 25% of the lower leaves. In r...
