Problems solved by technology

[0005] In view of this, the present invention provides a method for cultivating and planting tobacco plants and its application, which is used to solve the problem of slow rooting and poor seedling quality in the prior art due to the lack of soil in the root system of tobacco seedlings in the method of floating seedlings. Defects, further optimize the growth quality of tobacco plants and shorten the growth cycle of tobacco plants

Embodiment 1

[0023] Tobacco plants were cultivated by the method of floating seedlings, with 600 tobacco plants in each group. In this embodiment, the selected tobacco strains are conventional tobacco seedling varieties, which are not specifically limited here. Except for the operations specifically indicated by the following experimental groups, the rest of the operations are the same as the prior art.

[0024] Experimental group 1

[0025] Step 1, in the stage of floating seedling cultivation, apply seedling fertilizer to the tobacco plants at the stage of 75% seedling emergence; wherein, the amount of seedling fertilizer applied is 1 kg of seedling fertilizer per ton of water.

[0026] Step 2, the floating seedling raising stage, in the 3-leaf stage, apply the mixture of seedling-raising fertilizer and potassium indolebutyrate to the tobacco plant; The application amount is 10 g potassium indolebutyrate per ton of water.

[0027] Step 3, when transplanting, apply the potassium indole...

Embodiment 2

[0045] At the seedling stage, the growth status of flue-cured tobacco seedlings in experimental group 1, experimental group 2, experimental group 3 and the control group were measured, and the results are shown in Table 1.

[0046] Table 1 The growth of flue-cured tobacco seedlings at the seedling stage

[0047]

[0048]

[0049] Can get from table 1, the technical scheme provided by the present invention, compared with control group, flue-cured tobacco main root length, root system fresh weight, root system dry weight and root system vigor are all significantly different, further can show that the technical scheme provided by the present invention can obviously Promote the root growth of flue-cured tobacco. At the same time, in the experimental groups 1 to 3, the leaf color of the second leaf (the second tobacco leaf from top to bottom) was dark green, and its SPAD value was significantly higher than that of the control group.

Embodiment 3

[0051] The survey on the growth period of tobacco plants was carried out for two consecutive years. Please refer to Table 2 for the specific survey results. Two consecutive years of investigation can further investigate the deviation of experimental results caused by climate.

[0052] Table 2 Survey Form of Flue-cured Tobacco Growth Period

[0053]

[0054]Among them, the seedling time refers to the time from transplanting to survival; the rooting time refers to the time from the survival of the tobacco plant to the cluster; the flourishing time refers to the time from the cluster to budding. According to the test results of two years, it can be obtained from Table 2 that compared with the control group, the seedling time difference of the experimental group is obvious, and the seedling time of the experimental group is obvious, and compared with the control group, it enters the root elongation stage ahead of time; The time is also earlier than the control.

[0055] There...

Abstract

The invention belongs to the technical field of tobacco planting, and particularly relates to a tobacco plant cultivating and planting method and applications of the tobacco plant cultivating and planting method in the field of tobacco-plant strong seedling cultivation and in the field of early growth and quick tillering of tobacco plants. Experimental results show that, compared with existing planting technologies, the tobacco plant cultivating and planting method has the advantages that when float breeding of tobaccos is performed according to the method, growth of root systems of flue-cured tobaccos can be stimulated effectively, SPAD (soil and plant analyzer development) values of second leaves are improved remarkably, and seedling stage, resetting stage and root extending stage are shortened remarkably. By the tobacco plant cultivating and planting method and the applications thereof, the technical defects of slow rooting and poor seedling quality both caused by few soil attached to tobacco seedling root systems when float breeding methods are applied in the prior art are overcome, growth quality of the tobacco plants is further improved, and growth period of the tobacco plants is further shortened.

Description

technical field [0001] The invention belongs to the technical field of tobacco planting, and in particular relates to a method for cultivating and planting tobacco plants and its application. Background technique [0002] Tobacco plant, annual or limited perennial herb, Solanaceae; plant covered with glandular hairs, stem height 0.7-2 meters. Petiole indistinct or wing-like; panicle terminal, calyx tube-shaped or tube-shaped bell-shaped, corolla funnel-shaped, pink at the end; capsule, seed round or broadly oblong, yellowish brown; native to South America , cultivated all over the world. [0003] Tobacco plants are raw materials for the tobacco industry. my country began to study floating seedlings in the late 1990s. In the 20th century, the area of ​​floating seedlings was gradually promoted and became the dominant seedling method. It is expected that floating seedlings will still be the main seedlings for flue-cured tobacco seedlings in my country for a long time to come...
