Embodiment 1

[0018] Demonstration site selection: Xuanen Xiaoguan Gulu Village, where tobacco leaves have been planted continuously for 10 years, and soil-borne diseases in the tobacco field are seriously harmful.

[0019] Sweet potato and tobacco interleaving method: On April 25, 2017, the tobacco seedlings were transplanted in the field. The transplanting specification is that the row spacing between the tobacco seedlings is 120 cm, and the row spacing is 55 cm. On May 5, holes are drilled at a distance of 27.5 cm from the tobacco plants, and the hole depth is 5-10 cm. Insert the sweet potato seedlings, and then cover the holes with soil and press them. strict. One seedling per hole, one row per ridge, 1000 sweet potato seedlings / mu. On September 12, the sweet potatoes were dug manually, and the sweet potato vines were returned to the field.

Embodiment 2

[0021] Demonstration site selection: Luoquan Village, Xuanen Jiaoyuan, where tobacco leaves have been planted continuously for 10 years, and soil-borne diseases in the tobacco fields are seriously harmful.

[0022] Sweet potato and tobacco interleaving method: On May 1, 2017, the tobacco seedlings were transplanted in the field. The transplanting specification is that the row spacing between the tobacco seedlings is 120 cm, and the row spacing is 55 cm. On May 11, a hole is drilled at a distance of 27.5 cm from the tobacco plants. The hole depth is 5-10 cm. Insert the sweet potato seedlings, and then cover the holes with soil. Strictly pressed. One seedling per hole, one row per ridge, 1000 sweet potato seedlings / mu. On September 20th, the sweet potatoes were dug manually, and the sweet potato vines were returned to the field.

Embodiment 3

[0024] Demonstration site selection: Longfeng Qingbao Village, Enshi City, tobacco leaf planting has been planted continuously for 8 years, and soil-borne diseases in the tobacco field are seriously harmful.

[0025] Sweet potato and tobacco interleaving method: On May 3, 2017, the tobacco seedlings were transplanted in the field. The transplanting specifications are 120 cm row spacing between tobacco seedlings and 55 cm plant spacing. On May 15, a hole is drilled at a distance of 27.5 cm from the tobacco plant. The hole depth is 5-10 cm. Insert the sweet potato seedlings, and then cover the hole tightly with soil. . One seedling per hole, one row per ridge, 1000 sweet potato seedlings / mu. On September 20th, the sweet potatoes were dug manually, and the sweet potato vines were returned to the field.

Abstract

The invention relates to the technical field of tobacco planting soil ecological conservation, in particular to a method for ecological conservation of tobacco planting soil under an intercropping mode of tobaccos and potatoes. The method comprises the following steps of (1) selecting an intercropping sweet potato variety; (2) ridging; (3) fertilizing; (4) transplanting tobacco seedlings; (5) conducting sweet potato field planting; (6) conducting sweet potato harvesting; the method can improve a soil physical structure, promote beneficial microbial activities, reduce the number of harmful organisms in the soil, effectively improve the ecological environment of the tobacco planting soil, eliminate obstacles of continuous cropping, reduce the occurrence of soil-borne diseases, and achieve the reduction of labor and increase of efficiency for tobacco farmers.

Description

technical field [0001] The invention relates to the technical field of ecological conservation of tobacco planting soil, in particular to a method for ecological conservation of tobacco planting soil under the intercropping mode of tobacco and potatoes. Background technique [0002] Tobacco is one of the main economic crops in mountainous areas. In order to maximize profits, tobacco farmers use a large amount of chemical fertilizers. The multiple cropping index remains high. In addition, the lack of good fertility measures results in the destruction of soil physical structure, soil nutrients and microbial populations. The structural imbalance and the increase of the base of harmful organisms in the tobacco planting soil lead to more and more serious tobacco soil-borne diseases, threatening the stability and development of tobacco leaf production. Tobacco cultivation method: in CN201310372054.6, the height of the ridge for tobacco cultivation in CN201310372054.6 is 25-30cm, a...
