Embodiment 1

[0023] Embodiment 1: a kind of concave type ridge cultivation method of tobacco, see figure 2 , including the following steps:

[0024] (1) Ridging: A concave-shaped tobacco ridge is formed in the tobacco field. The shape of the concave-shaped tobacco ridge is: the height h1 of the ridge is 30-40cm, and the top of the tobacco ridge is sunken downward, forming the ridge walls on both sides and the depression in the middle , the cross-section of the depression is an inverted trapezoid, the depth h2 of the depression is 20-25cm, and the width a of the upper opening of the depression is 40-60cm; A drainage port, the drainage port communicates the depression with the outside of the smoke ridge;

[0025] (2) Transplanting and film covering: transplant the tobacco seedlings into the depression of the tobacco ridge, and cover the top of the tobacco ridge with thickened plastic film after transplanting. The seedlings are 5-10cm away from the plastic film;

[0026] (3) Remove the fi...

specific Embodiment approach

[0029] The existing "turtle-shaped" tobacco ridge cultivation method usually has a width of 110-130cm and a height of 20-30cm, and the tobacco seedlings are directly transplanted on the arc-shaped top of the ridge, see figure 1 When cultivating soil, the soil needs to be cultivated on the top of the tobacco ridge. Since the top of the tobacco ridge itself is arc-shaped, the new soil on the upper part is easy to slide down along the sides of the tobacco ridge when cultivating soil, and the stem position of the tobacco plant cluster is relatively high in the later stage, so soil cultivation The operation is labor-intensive and time-consuming, which is not conducive to the operation of mechanical soil cultivation. In addition, the height of soil cultivation is also limited. Usually, the height of soil cultivation h3 is not easy to exceed 10cm. The plastic film mulching technology that matches this kind of tobacco ridge cultivation method is to cover the tobacco ridge with plastic ...

Abstract

The invention discloses a medium concave ridging culture method for tobacco, and aims at solving the technical problems of difficult operation in film opening and oil covering, work and time waste and poor mechanical soil covering in the existing tobacco ridging culture technology. The method comprises the steps of (1) ridging, namely, forming medium concave tobacco ridges in a tobacco field; (2) transplanting and covering with film, namely, transplanting tobacco seedlings into the sunken parts of the smoke ridges, and covering a mulching film on the top part of the tobacco ridge after transplanting, so that the tobacco seedlings can grow below the film; (3) opening the film and covering with soil, namely, removing the mulching film at the resettling growth stage of the tobacco seedling growing, filling soil from two side ridge walls into the sunken parts to achieve film opening and soil covering. According to the method, the film opening and soil covering can be achieved; the problem that the film opening and soil covering are difficult to popularize in the existing field of tobacco planting; in addition, the film opening and soil covering are convenient to operate; the labor cost and working hours in tobacco planting can be saved; meanwhile, the method has the advantages of preventing diseases, resisting drought and increasing output; the method is beneficial for the tobacco plant growing, can improve the tobacco quality, and can be widely popularized in the field of tobacco planting.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a concave ridge cultivation method for tobacco. Background technique [0002] Ridging cultivation technology is a commonly used method in the process of transplanting tobacco seedlings. Ridging cultivation in tobacco fields is beneficial to prevent floods and droughts, and reduce diseases. Seedlings grow. Ridging cultivation is often used in conjunction with plastic film mulching technology. Plastic film mulching before and after transplanting tobacco seedlings can improve soil water, fertilizer, air, and heat conditions, increase ground temperature, maintain water, improve soil physical and chemical properties, increase fertilizer utilization and reduce pests. At present, the ridge formed by the conventional tobacco field ridging machine is "turtle-shaped", and the upper surface of the ridge is in a convex arc shape. The ridge of this shape is difficult, labor-intensi...
