Embodiment 1

[0025] In Example 1, there were 10 tobacco plants in the standard group, and the technique of "threshing leaves and leaving flowers" was adopted on the day of flowering;

[0026] After the flower buds of the control group appear, shade the inflorescence with a shading material to prevent the flower buds from seeing light. The first control group has 10 tobacco plants, and the cycle of removing the flower buds is set to 10 days, and the cycle of removing the upper tobacco leaves is set to 20 days;

[0027] The second control group has 10 tobacco plants, and the cycle of removing flower buds is set to be 13 days, and the cycle of removing upper tobacco leaves is set to be 20 days;

[0028] The third control group has 10 tobacco plants, and the period of removing flower buds is set to be 16 days, and the period of removing upper tobacco leaves is set to be 20 days;

[0029] The flower bud removal cycle is divided into six time points, following the order from bottom to top and fr...

Embodiment 2

[0033] In Example 2, there were 10 tobacco plants in the standard group, and the technique of "threshing leaves and leaving flowers" was adopted on the day of flowering;

[0034] After the flower buds of the control group appear, shade the inflorescence with a shading material to prevent the flower buds from seeing light. The first control group has 10 tobacco plants, and the cycle of removing the flower buds is set to 12 days, and the cycle of removing the upper tobacco leaves is set to 6 days;

[0035] The second control group has 10 tobacco plants, and the cycle of removing buds is set to be 12 days, and the cycle of removing upper tobacco leaves is set to be 12 days;

[0036] The third control group has 10 tobacco strains, and the setting cycle of removing flower buds is 12 days, and the setting cycle of removing upper tobacco leaves is 18 days;

[0037] The flower bud removal cycle is divided into six time points, following the order from bottom to top and from outside to...

Embodiment 3

[0041] In Example 3, there were 10 tobacco strains in the standard group, and the technology of "threshing leaves and leaving flowers" was adopted;

[0042] After the flower buds of the control group appeared, the inflorescences were covered with shading materials to prevent the flower buds from being exposed to light. The first control group had 10 tobacco plants, and the cycle of removing flower buds was set to 15 days, and the cycle of removing the upper tobacco leaves was set to 15 days; the flower buds retained at the end were removed from the light. Material;

[0043] The second control group has 10 tobacco strains, and the cycle of removing flower buds is set to be 6 days, and the cycle of removing upper tobacco leaves is set to be 6 days;

[0044] The third control group has 10 tobacco plants, and the cycle of removing buds is set to be 20 days, and the cycle of removing upper tobacco leaves is set to be 20 days;

Abstract

Disclosed is a method for planting tobacco leaves of flue-cured tobacco. The method comprises the following steps that after tobacco plants grow to form buds, inflorescences of the buds are shielded through a shading material; after the buds are shielded, a bud removal period is set, and the buds are removed in a picking mode step by step from bottom to top and from exterior to interior; after the buds are shielded, an upper tobacco leaf removal period is set, and tobacco leaves with the length smaller than 15cm are removed in a picking mode step by step; in the last stage of the bud removal period, the shading material is removed, and flowers at the top ends of the tobacco plants are reserved. Different topping means are provided according to features of plant growth, nutrients can guarantee maturity of tobacco leaves in the middle through restraint of maturity of the buds, and it is believed that when a bud opening period is prolonged, the sufficient time is provided for maturity of tobacco leaves on the upper portion; meanwhile, stimulation of growth factors in the process of damage on the apical dominance is reduced to the maximum extent, and generation of nicotine is avoided; the yield is kept, and the finished product grade of the tobacco leaves is guaranteed.

Description

technical field [0001] The invention relates to a method for planting plants, in particular to a method for planting tobacco leaves. Background technique [0002] The planting parts of tobacco leaves can be divided into five parts: the lower 2-3 leaves of the tobacco plant are called foot leaves, the upper 4-5 leaves are called lower second shed leaves, and the middle 4-6 leaves are called waist leaves. leaves, the 4-5 leaves in the middle are called Shangerpeng leaves, and the 3-4 leaves at the top of the tobacco plant are called top leaves. The foot leaves and the lower two shed leaves are collectively called the lower leaves, and the upper two sheds and the top leaves are collectively called the upper leaves. The inflorescence of tobacco is a panicle-shaped cyme, and the calyx is bell-shaped. It is a limited inflorescence, in which a central flower at the top of the flower axis opens first, and when the growth of the main flower axis is limited, it continues to grow from...
