Problems solved by technology

[0004] Among the existing technologies, technologies such as no-tillage, ridging, and mulching can reduce soil erosion in mountainous tobacco fields to a certain extent, and have been applied in my country's Henan, Guizhou, Sichuan and other tobacco areas. However, these technologies reduce soil erosion in slope tobacco fields has very limited effect

Embodiment 1

[0024] Such as figure 1 As shown, the method for reducing soil erosion in slope tobacco field of the present embodiment comprises the following steps:

[0025] 1) Before ridging, apply chemical fertilizers horizontally along the extension direction of the contour line of the slope to form a strip-shaped fertilizer belt. The amount of fertilizer applied is selected according to the nutrient status and conventional consumption of the local tobacco soil; the slope of the slope of the present embodiment is 7.3°;

[0026] 2) Use a small ridge filming machine to form ridges along the extension direction of the contour line of the slope, and cover the ridges with plastic film 1 to ensure that the fertilizer applied is just below the ridges; the distance between two adjacent ridges is 110cm, the spacing refers to the distance between the centerline of the top of one ridge and the centerline of another adjacent ridge; the height of the ridge is 25cm, the width of the bottom of the rid...

Embodiment 2

[0032] The gradient of the slope of the present embodiment is 10°, and others are all the same as in Embodiment 1.

Abstract

The invention relates to a method for reducing water and soil loss of sloping tobacco field, and belongs to the technical field of tobacco planting. The method for reducing the water and soil loss ofthe sloping tobacco field comprises the following steps that 1, ridges are formed in the contour line extending direction of a slope, and the ridges are covered with films; 2, alfalfa is planted in furrows, and tobacco is planted on the tops of the ridges; 3, after the tobacco is harvested, the alfalfa in the furrows is turned over and returned to the field. According to the method for reducing the water and soil loss of the sloping tobacco field, the way of transverse ridging is adopted, the water and soil loss is sufficiently reduced, the ridges are covered with the films, the alfalfa is planted in the furrows, mulching film and alfalfa binary covering is achieved, and the immobilization effect on the water and soil is further enhanced.

Description

technical field [0001] The invention relates to a method for reducing water and soil loss in sloping tobacco fields, and belongs to the technical field of tobacco planting. Background technique [0002] Tobacco is an important economic crop and an important source of national economy. Due to the high climate requirements for tobacco cultivation, many areas suitable for tobacco cultivation in my country are located in mountainous and hilly areas. Mountain tobacco has become one of the important types of tobacco leaf production in my country and is an important source of raw materials for the cigarette industry. [0003] In the process of tobacco planting, due to the long-term pursuit of yield and quality as the goal of farming methods, tobacco leaf production has performed too frequent operations on the soil. When the rainfall is heavy, the amount of water and soil loss increases, which increases environmental risks and leads to a decline in soil fertility. When the climate ...
