Problems solved by technology

[0004] Tobacco is a crop that requires a lot of water. The total amount of rainfall in southern my country is sufficient, but the distribution of time and space is uneven, especially not matching the water demand of tobacco plants. Rainfall in the middle and late stages of tobacco plant growth often cannot guarantee the normal development and growth of tobacco plants , and because the water retention capacity of the tobacco field is poor, and it is easy to make the applied chemical fertilizer not be fully dissolved and absorbed in time, which affects the nutrient uptake of the tobacco plant
For this reason, a large number of water conservancy irrigation facilities have been built in major tobacco leaf producing areas to solve the drought problem, and good results have been achieved. However, due to the large investment in facilities, they have not been fully promoted.

Embodiment approach

[0013] In 2014, this technology was implemented in Cuiba Town, Enshi City, Hubei Province, and the cultivar was Burley Eyan No. 1. The implementation of water retention and heat preservation cultivation is carried out according to the following scheme: 1. Soil preparation and fertilization: operate according to the conventional tobacco production technical regulations; 2. Ridging: ridge height (b) 25 cm, ridge bottom width (a) 80 cm, ridge surface width ( c) 40 cm; 3. Set up a water-retaining and heat-preserving ditch, suitable for moisture mulching: dig a water-retaining and heat-retaining ditch along the axis of the ridge on the ridge surface, and its specifications are ditch depth (f) 10 cm, ditch width (d) 12 cm, The bottom width (e) is 2 cm; when the water holding capacity in the field reaches 80%, cover the whole ridge body with agricultural plastic film, and it is required to form a water storage and heat storage cavity in the water retention and heat preservation ditch ...

Abstract

The invention provides a tobacco water-holding and heat-preserving cultivation method, and particularly a cultivation mode in which a water-holding and heat-preserving ditch is formed on a ridge body to collect naturally falling water, increase soil moisture content inside the ridge and increase heat storage capability of the ridge body on the basis on the conventional tobacco ridging and mulching-film cultivation. The method can solve the problems of tobacco production caused by periodic drought, and has the characteristics of being simple to operate and easy to generalize.

Description

[0001] technical field [0002] The invention provides a water-retaining and heat-retaining cultivation method for tobacco, which relates to the field of tobacco cultivation.
