Problems solved by technology

After the tobacco leaves turn green, it is difficult to enter the normal mature state in a short period of time. At this time, if the green leaves are picked and roasted, it is easy to roast blue tendons and hang gray smoke. Postpone the normal sowing of the next crop

Embodiment 1

[0025] A kind of ripe stage green tobacco leaf turning green circumcision, root-cutting processing method, according to the SPAD value rapid diagnosis fresh tobacco leaf turning green degree, specifically comprises the following steps:

[0026] (1) Girdling treatment: remove the epidermis phloem of the tobacco stalk during circumcision, and the upper and lower width of the knife edge is 0.8-1 cm.

[0027] Class I turning green tobacco plants: Cut a half circle from the base of the stem along the 10cm height of the plant.

[0028] Class II turning green tobacco plants: cut half circles from the base of the stem along the heights of 10cm and 20cm, and the two half circles are symmetrically distributed.

[0029] Class III turning green tobacco plants: cut half circles from the base of the stem along the plant heights of 10cm, 20cm, and 30cm, and the three half circles are distributed in a symmetrical plane.

[0030] (2) root removal treatment:

[0031] Class I turning green tob...

Abstract

The invention discloses a girdling and root cutting treatment method for reviving of green tobacco leaves in a mature period. The girdling and root cutting treatment method comprises the following steps that class I reviving tobacco plants are girdled for half a circle from stem bases along the position with the plant height of 10 cm; class II reviving tobacco plants are girdled for half a circle from stem bases along the positions with the plant height of 10 cm and 20 cm; class III reviving tobacco plants are girdled for half a circle from stem bases along the positions with the plant heights of 10 cm, 20 cm and 30 cm; root systems of the class I reviving tobacco plants are vertically cut off downwards in the ridge surface direction at the positions 15 cm away from tobacco plant stalks, wherein the section width is about 15 cm, and the section depth is about 25 cm; root systems of the class II reviving tobacco plants are vertically cut off downwards in the ridge surface direction at the positions 10 cm away from tobacco plant stalks, wherein the section width is about 15 cm, and the section depth is about 25 cm; and root systems of the class III reviving tobacco plants are vertically cut off downwards in the ridge surface direction at the positions 5 cm away from tobacco plant stalks, wherein the section width is about 15 cm, and the section depth is about 25 cm. According to the method, different kinds of treatment are carried out according to different fresh tobacco leaf reviving degrees, and the mature-period green tobacco leaf reviving phenomenon is effectively reduced.

Description

technical field [0001] The invention relates to a treatment method for turning green tobacco leaves at a mature stage, circumcision and root cutting, and belongs to the technical field of tobacco planting. Background technique [0002] The so-called turning green smoke refers to the phenomenon that the tobacco leaves that have reached maturity or are close to maturity in the field turn green and tender after a long period of rainy and seldom-lit weather, and lose their original mature characteristics. The reason for the greening of tobacco leaves is mainly related to the reabsorption of nitrogen by tobacco plants. Under normal circumstances, the absorption and utilization of nitrogen by tobacco plants reaches the peak before and after budding, and then decreases significantly, and the tobacco leaves mature gradually. Due to the uneven distribution of drought, precipitation, light and other factors during the growth of flue-cured tobacco, there will be great differences in t...
