Embodiment 1

[0023] In this example, KRK26 was planted in Yuxi Mountain in 2016, which specifically included the following steps:

[0024] 1) Site selection: Prepare the planting area selection plan in advance. The soil texture is loam, with a sand content of 40%-55%, and an altitude of 1900-2100m. The terrain is relatively flat, with good ventilation, sufficient rainfall, and strong sunlight. The previous stubble is a fallow land, so as not to delay the timely transplanting of this variety. The soil is slightly acidic with a pH of 5-5.5.

[0025] 2) Ridging: deep plowing and plowing 35cm deep, sun-dried for 40 days, and then rake the soil moisture, so that the soil rills are straight, the moisture surface is full, the moisture direction of each block in the same contiguous area is uniform, and the smoke ponds are uniform; Moisture height should not be lower than 30cm, and the side ditch and waist ditch should be 5cm deeper than the moisture ditch to ensure smooth drainage;

Embodiment 2

[0057] In this example, KRK26 was planted in Yuxi Mountain in 2017, which specifically included the following steps:

[0058] 1) Site selection: Prepare the planting area selection plan in advance. The soil texture is loam-sandy soil, with a sand content of 40%-55%, and an altitude of 1900-2100m. The terrain is relatively flat, well ventilated, with sufficient rainfall and strong sunlight . The previous stubble is an early-maturing variety, so as not to delay the timely transplanting of this variety. The soil is slightly acidic with a pH of 5-5.5.

[0059] 2) Ridging: deep plowing and deep plowing of 35cm, sun-dried for 40 days, and then raking the geographical moisture, so that the soil rills are straight, the moisture surface is full, the moisture direction of the plots in the same contiguous area is uniform, and the smoke ponds are uniform; The height is not less than 30cm, and the side ditch and waist ditch are more than 5cm deeper than the moisture ditch to ensure smoot...

Embodiment 3

[0090] In this example, KRK26 was planted in Yuxi Mountain in 2018, which specifically included the following steps:

[0091] 1) Site selection: Prepare the planting area selection plan in advance. The soil texture is loam-sandy soil, with a sand content of 40%-55%, and an altitude of 1900-2100m. The terrain is relatively flat, well ventilated, with sufficient rainfall and strong sunlight . The previous stubble is an early-maturing variety, so as not to delay the timely transplanting of this variety. The soil is slightly acidic with a pH of 5-5.5.

[0092] 2) Ridging: deep plowing and deep plowing of 35cm, sun-dried for 40 days, and then raking the geographical moisture, so that the soil rills are straight, the moisture surface is full, the moisture direction of the plots in the same contiguous area is uniform, and the smoke ponds are uniform; The height is not less than 30cm, and the side ditch and waist ditch are more than 5cm deeper than the moisture ditch to ensure smoot...

Abstract

The invention relates to a method for producing and planting KRK26 tobacco in a high-altitude mountainous region, and belongs to the technical field of production and planting of flue-cured tobacco. The method comprises the following key steps: field management including land selection, ridging and transplanting, fertilizing, pine needle covering, ridging and the like and ripening and harvesting.A mountain tobacco planting area with relatively high sand content, sufficient light, heat and water and an altitude of 1900-2100 m is selected, ridging is carried out according to requirements, fertilizers are applied reasonably, nitrogen is controlled, phosphorus is stabilized, and trace fertilizers are increased and supplemented; the transplanting period is generally April 10th to April 20th ,and the field growth period is ensured to be about 150 days; 4-7 kg of pure nitrogen is applied per mu according to different fertility levels, soil moisture surface is covered with pine needles, and500-800 kg of the pine needles are used per mu; and proper field management is carried out, topping is carried out in good time, and the tobacco is harvested when the tobacco is ripe. According to theKRK26 which is produced and planted by the method, the output value per mu and the proportion of middle and upper grade tobacco are effectively improved, the quality of tobacco leaves is good, and the industrial usability is high.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco production and planting, and in particular relates to a method for producing and planting KRK26 tobacco in high-altitude mountains. Background technique [0002] The KRK26 variety has been favored by industrial enterprises for its soft and delicate texture and harmonious internal chemical composition. This variety was selected and bred by the Zimbabwe Tobacco Research Institute, and it was introduced into Yunnan for trial planting in 2006. Its overall performance is good and it has become the best among the newly introduced varieties. [0003] During the popularization and demonstration process, due to the unique characteristics of the KRK26 variety, conventional production and planting methods in high-altitude mountain tobacco areas are prone to excessive growth in the field, serious occurrence of two black diseases, difficulty in mature harvesting, and more green stems and yellow flak...
