Problems solved by technology

[0004] At present, domestic cultivation measures and related reports on tobacco transplanting are mostly found in pit-type seedling transplanting, film seedling transplanting, film seedling transplanting, and film-free transplanting, etc., but most of these transplanting methods are the first. Transplanting after the ridge also means that the root system of the tobacco plants under this method is mostly limited to the height of the ridge surface built before transplanting. The effective nutrient absorption

Embodiment 1

[0046] (1) Transplanting tobacco seedlings on flat ground: Before transplanting, the tobacco field should be plowed deeply for 30 cm, and the land should be leveled after the cracking. Timely mix the pond and apply tobacco special compound fertilizer 350kg / hm 2 And calcium magnesium phosphate fertilizer 200kg / hm 2 , After transplanting, water 1.5L / plant with fixed root water. The tobacco seedlings are Safflower Dajinyuan.

[0047] (2) Intertillage weeding and gradual ridging:

[0048] A. For the first intertillage, lightly hoe the tobacco plants at a distance of 2.5cm, only break the ground near the seedlings without turning the soil, and do not move the seedlings. At the same time, carry out the operation of ridges and soil cultivation. The ridges and furrows should be 7cm;

[0049] B. For the second intertillage, hoe 10cm deep between rows, 6cm intertillage depth between plants, hoe thoroughly and evenly, and perform ridge cultivation operation at the same time, so that t...

Embodiment 2

[0056] (1) Transplanting tobacco seedlings on flat ground: Before transplanting, the tobacco field should be plowed 40cm deep, and the land should be leveled after the cracking. The row spacing of flue-cured tobacco plants should be 50cm×120cm. Timely mix the pond and apply tobacco special compound fertilizer 400kg / hm 2 And calcium magnesium phosphate fertilizer 275kg / hm 2 , Water 2.0L / plant with fixed root water after transplanting. The tobacco seedlings are K326.

[0057] (2) Intertillage weeding and gradual ridging:

[0058] A. For the first intertillage, lightly hoe the tobacco plants around 4.5cm, only break the ground near the seedlings without turning the soil, and do not move the seedlings. At the same time, carry out the operation of ridges and soil cultivation, and the ridges and furrows are 8cm;

[0059] B. For the second intertillage, hoe between rows 10-15cm deep, intertillage depth between plants 6-8cm, hoe thoroughly, hoe evenly, and simultaneously carry out ...

Embodiment 3

[0066] (1) Transplanting tobacco seedlings on flat ground: Before transplanting, the tobacco field should be plowed 35cm deep, and the land should be leveled after the cracking. Apply compound fertilizer 375kg / hm special for tobacco in ponds from time to time 2 And calcium magnesium phosphate fertilizer 235kg / hm 2 , After transplanting, pour 1.75L / plant of fixed root water. The tobacco seedlings are Yunyan 87.

[0067] (2) Intertillage weeding and gradual ridging:

[0068] A. For the first intertillage, lightly hoe the tobacco plants around 3cm, only break the ground near the seedlings without turning the soil, and do not move the seedlings. At the same time, carry out the operation of ridges and soil cultivation. The ridges and furrows should be 10cm;

[0069] B. For the second intertillage, hoe between the rows to a depth of 11cm, intertillage between the plants to a depth of 7cm, hoe thoroughly and evenly, and at the same time carry out the ridge cultivation operation, s...

Abstract

The invention discloses a gradual ridging cultivation method for efficiently cultivating tobacco roots. The gradual ridging cultivation method comprises the steps of flat tobacco seedling transplanting, intertillage for weeding, gradual ridging and topdressing. Accordingly, the tobacco roots can be efficiently cultivated, penetration depth of the roots of the underground part of tobacco is enhanced, fibrous roots are enriched, the number of adventitious roots is increased, nicotine synthesis is facilitated, the tobacco leaf yield is increased, the tobacco leaf quality is improved, the tobaccostrain resistance is improved, the tobacco leaf field maturity and tolerance is improved, and leaf ageing and full ripe stage are delayed; by means of flat transplanting, a mechanical intertillage weeding hiller is introduced conveniently, application of a herbicide and tobacco pesticide residue damage are reduced, the tobacco cultivation efficiency is improved, the labor time is shortened, and the income of tobacco growers is increased.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation, and in particular relates to a step-by-step ridging cultivation method for efficiently cultivating tobacco root systems. Background technique [0002] Tobacco, especially flue-cured tobacco, is one of the important economic crops in my country. In 2017, the planting area of ​​flue-cured tobacco in my country has reached 14.822 million mu, accounting for more than 20% of the world's total. About 7%. Therefore, the scientific and effective flue-cured tobacco cultivation technology is conducive to improving the yield and quality of tobacco leaves, which affects the economic income of tobacco farmers and national fiscal revenue. [0003] The root system plays a role of physical support for the growth of tobacco. At the same time, most of the minerals and water required by the tobacco plant are absorbed from the soil through the root, and the root system is also the synthetic organ of toba...
