Gradual ridging cultivation method for efficiently cultivating tobacco roots

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...

AI Technical Summary

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 area of ​​the root system weakens the stress resistance of the tobacco plant, and the maturity of the tobacco leaves is not resistant to nutrition, which reduces the yield and quality of the tobacco leaves

In addition, due to the cultivation method of ridging first and then transplanting, it hinders the promotion of mechanized transplanting in the early stage and mechanized intertillage and weeding equipment in the later stage, which reduces agricultural production efficiency and increases labor time and cost.
