Embodiment 1

[0025] The test will be carried out in 2020. The test site is located in Dapo Township, Zhanyi District, Qujing City, Yunnan Province. The type of tobacco field is a mountain tobacco field.

[0026] According to (local conventional flue-cured tobacco cultivation method): do not return straw to the field during pre-planting; before transplanting flue-cured tobacco, make ridges and ponds, the height of the ridges is 20 cm, and the depth of the pond is 10 cm; no plastic film is used; fertilization is divided into three times: on the day of transplanting Apply 30% tobacco-specific fertilizer to the pond, then transplant flue-cured tobacco, apply 40% of the total amount of tobacco-specific fertilizer 35 days after transplanting flue-cured tobacco, and apply another 30% 45 days after transplanting flue-cured tobacco.

Embodiment 2

[0028] The test will be carried out in 2020. The test site is located in Dapo Township, Zhanyi District, Qujing City, Yunnan Province. The type of tobacco field is a mountain tobacco field.

[0029] According to (the cultivation method of flue-cured tobacco of the present invention): before the pre-soil preparation, the wheat straw (5cm) of 600kg / mu is evenly sprinkled on the field, and then plowed; , the depth of the pond is 20cm; when fertilizing, first apply 50% of the fertilizer to the bottom of the pond (evenly mixed with the soil) and cover it with pond soil, and the other 50% of the fertilizer ring is applied near the inner side of the pond mouth (about 15cm in diameter); after fertilization is completed Cover with agricultural film, and break the film at the center of the smoke pond to open a large opening (opening 7cm), then transplant the tobacco seedlings and cover the roots with fine soil; the film covering period is from transplanting flue-cured tobacco to when the...

Embodiment 3

[0031] The test will be carried out in 2020. The test site is located in Zhaowei Village, Hongta District, Yuxi City, Yunnan Province. The type of tobacco field is Ba District Tobacco Field.

[0032] According to (local conventional flue-cured tobacco cultivation method): do not return straw to the field during pre-soil preparation; ridges and ponds are formed before transplanting flue-cured tobacco, the height of the ridges is 25cm, and the depth of the pond is 15cm; no plastic film is used; fertilization is divided into three times: on the day of transplanting Apply 50% tobacco-specific fertilizer to the mixing pond, then transplant flue-cured tobacco, apply 30% of the total amount of tobacco-specific fertilizer 35 days after transplanting flue-cured tobacco, and apply another 20% 45 days after transplanting flue-cured tobacco.

Abstract

The invention belongs to the technical field of flue-cured tobacco cultivation, and particularly relates to a flue-cured tobacco cultivation method capable of reducing labor and cost, saving fertilizer and improving efficiency. The method comprises the following steps: (1) straw returning to the field during soil preparation in advance: before soil preparation in advance, rice or wheat straw is uniformly spread to the field, and then ploughing is performed; (2) high ridging before transplanting: performing high ridging before transplanting; (3) deep pond digging: digging the deep pond in the ridged tobacco field; (4) one-time double-layer fertilization: applying 50% of fertilizer to the bottom of the pond, uniformly mixing the fertilizer with soil, covering the pond with pond soil, and circularly applying the other 50% of fertilizer to a position close to the inner side of a pond opening; (5) film mulching and transplanting: performing agricultural film mulching after fertilization is completed, breaking the film and opening in the center of the tobacco pond, then transplanting tobacco seedlings, and covering the roots with fine soil. The film covering period is from flue-cured tobacco transplanting to flue-cured tobacco harvesting; the labor for tobacco production is reduced, and the fertilizer utilization efficiency is increased, so that the sustainable development of flue-cured tobacco production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco cultivation, and in particular relates to a method for cultivating flue-cured tobacco by reducing labor and cost, saving fertilizer and increasing efficiency. Background technique [0002] In recent years, the labor gap in flue-cured tobacco production has been increasing and the cost of raw materials has been rising year by year. Therefore, how to reduce the labor cost of tobacco leaf production and increase the planting benefits of tobacco farmers has become a problem that must be faced in the current tobacco leaf work. On the other hand, the fertilizer utilization rate in my country is obviously low at present, which not only leads to a huge waste of resources, but also easily causes serious environmental risks or environmental pollution. Under the above background, it is imperative to actively explore technical approaches that can reduce labor in tobacco leaf production and increas...
