Problems solved by technology

Usually, in tobacco potting, if cultivation soil, or forest soil, grassland soil, etc. are used as cultivation soil, the soil structure is relatively dense, and the water permeability is poor; if sandy soil is used as cultivation soil, the soil structure is loose and the organic matter content is low. Poor water holding capacity and fertilizer retention, leakage of water and fertilizer, resulting in water and fertilizer loss; commercialized substrates also have poor water retention and fertilizer retention, and very weak root fixation ability; currently there is no tobacco potting substrate on the market that can take into account ventilation, water retention and fertilizer
In addition, the layout of tobacco pots is often simple and evenly distributed, and the management of water and fertilizer is carried out separately during the cultivation process, which is not well coordinated

Embodiment 1

[0028] (1) Select a cultivation container: select a cultivation container with a caliber of 30cm, a height of 20cm, and 3 equal-spaced drainage holes at a distance of 3cm from the bottom of the container, with a diameter of 3mm. The barrel-shaped container is made of plastic, and the wall thickness of the container is 1mm.

[0029] (2) Filling substrate: first fill the bottom of the container with 5 cm thick sand, and then fill the sand with cultivation soil mixed with sand and commercial tobacco seedling cultivation substrate at a volume ratio of 3:1, until it is lower than the container mouth at a height of 2 cm. The sand is mountain sand with a particle size of 0.10-0.25 mm.

[0030] (3) Potted plant layout: The layout is determined according to the size of the potted plants. When the scale does not exceed 1000 plants, the field plant row spacing is used for cultivation. When the scale exceeds 1000 plants, the 2-row square box cultivation is used. The compartment spacing ...

Embodiment 2

[0033] (1) Select a cultivation container: select a cultivation container with a diameter of 40 cm, a height of 25 cm, and 4 drainage holes at equal intervals at a distance of 4 cm from the bottom of the container, with a diameter of 4 mm. The barrel-shaped container is made of plastic, and the wall thickness of the container is 3mm.

[0034] (2) Filling substrate: first fill the bottom of the container with 6 cm thick sand, and then fill the sand with cultivation soil mixed with commercial tobacco seedling substrate at a volume ratio of 4:1, until it is lower than the container mouth at a height of 2.5 cm. The sand is river sand with a particle size of 0.35-0.50 mm.

[0035] (3) Potted plant layout: The layout is determined according to the size of the potted plants. When the scale does not exceed 1,000 plants, the field plant row spacing is used for cultivation. When the scale exceeds 1,000 plants, the 3-row square box cultivation is used. The compartment spacing of the co...

Embodiment 3

[0038] (1) Select a cultivation container: select a cultivation container with a diameter of 45cm, a height of 30cm, and 6 equal-spaced drainage holes at a distance of 5cm from the bottom of the container, with a diameter of mm. The barrel-shaped container is made of plastic, and the wall thickness of the container is 5mm.

[0039] (2) Filling substrate: first fill the bottom of the container with 8 cm thick sand, and then fill the sand with cultivation soil mixed with commercial tobacco seedling cultivation substrate at a volume ratio of 6:1, until it is lower than the container mouth at a height of 3 cm. The sand is a mixture of mountain sand with a particle size of 0.10-0.25mm and river sand with a particle size of 0.35-0.50mm in any proportion.

[0040] (3) Potted plant layout: The layout is determined according to the size of the potted plants. When the scale does not exceed 1,000 plants, the row-spacing cultivation of field plants is adopted. When the scale exceeds 1,00...

Abstract

The invention discloses a tobacco potted planting method and its application, comprising the following steps: (1) selecting a cultivation container, (2) filling a substrate, (3) potted plant layout, (4) potted plant management; Inexpensive, easy to obtain, less substrate used, saving resources, relatively light substrate, low cultivation labor intensity, cultivated tobacco plants are not easy to lodging, the root system is developed, the roots are shallow, and the roots are wide. The roots will not come out of the container, which is convenient Mobile, long-distance transportation, the cultivation process is close to field cultivation of tobacco production, saving space, suitable for open-air, greenhouse, greenhouse pot plant seed production of large tobacco varieties, as well as pot plant experiments such as breeding, cultivation, plant protection, and baking.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation, and in particular relates to a tobacco potted cultivation method and its application. Background technique [0002] Most of the plant types of cultivated tobacco are relatively large. In order to allow the tobacco plants to grow normally during potting, most of them use flowerpots or plastic barrels with larger diameters. The height of these cultivation containers is generally more than 40cm, and the bottom has water seepage holes to prevent the tobacco plants from turning over and accumulating water. Most of the cultivation substrates used are cultivated soil, or forest soil and grassland soil, which are relatively large in volume and quality. The rear roots of the cultivated tobacco plants often pass through the seepage holes at the bottom of the container, or take root in the potted field, or grow aerially on the bottom of the pot. It is easy to move, even if it is barely moved, i...
