Problems solved by technology

According to the tracking and monitoring in recent years, tobacco farmers adopt the "tobacco-rice rotation" or "tobacco-vegetable rotation" model every year, which can bring about 2,500 yuan per mu per year. However, this model has the following problems: First, flue-cured tobacco must Harvested before mid-July, mid-July to mid-August, the climate resources with good temperature and light conditions cannot be used, resulting in light color, thin slices, light flavor of tobacco leaves, decline in internal quality, and low cigarette prices
Second, the season is tense, and the phenomenon of extensive tillage and intensive planting is serious. The arrangement of rice varieties can only be dominated by early indica rice with a short growth period, with low yield and poor rice quality.
So far, there is no report of interplanting sweet potato with tobacco

Embodiment 1

[0023] Embodiment 1: a kind of interplanting method of sweet potato and flue-cured tobacco, comprises the following steps: a. Ridging and making belt: adopt the ridge box planting mode, press ridge width 60-80cm, ridge height on the selected plot in late March 20-30cm specifications are used for belting, and the ridges should be carried out in a horizontal direction to prevent water and soil erosion; b. Mulching film: When covering the mulch film, it is required to stretch the mulch film tightly and flatten it. The plastic film is closely attached to the ridge surface, and a small piece of soil is pressed on the ridge surface film at a certain distance, which is relatively airtight; c. Transplanting flue-cured tobacco: transplanting the cultivated tobacco from late April to early May Seedlings should be planted in the morning and evening or on cloudy days. Avoid noon on a sunny day, and you can also choose to transplant in light rainy days. The seedlings are in the seedbed stag...

Embodiment 2

[0024] Embodiment 2: a kind of interplanting method of sweet potato and flue-cured tobacco, comprises the following steps:

[0025] (1) Ridging and belting: adopt the planting method of ridge box, and in the second ten days of March, on the selected plot, the ridge width is 60-80cm, and the ridge height is 20-30cm. carried out to prevent soil erosion.

[0026] (2) Mulching film: When covering the mulch film, it is required to stretch the mulch film tightly and flatten it. The two ends and both sides should be compacted with soil, so that the mulch film is tightly attached to the ridge surface, and a small piece of mulch film is pressed on the ridge surface at a certain distance. The soil is in a relatively closed state.

[0027] (3) Tobacco transplanting: Tobacco seedlings are transplanted from late April to early May. The seedbed period is 50-55 days, the stem height is 3-5 cm, and 4-5 functional leaves. The seedlings should be uniform in size, strong in growth, free from p...

Embodiment 3

[0032] Embodiment 3: a kind of interplanting method of sweet potato and flue-cured tobacco, comprises the following steps:

[0033] An orthogonal experiment of tobacco and potato interplanting was carried out under the same soil conditions in a county in Wuling mountainous area. Considering that sweet potato and tobacco are both potassium-loving crops, the experiment was designed as a gradient three-factor experiment of NPK fertilizer. The plots were randomly arranged and repeated 3 times. Shangshu 19, a high-yield and high-quality variety with medium and short vines, was selected as sweet potato, and Burley tobacco, which is widely planted in this area, was selected as tobacco. The interplanting method uses the steps of Example 1.

[0034] The test results show that the best cultivation mode is to apply 40-50 kg of special fertilizer for tobacco leaves per mu, and then apply 12-17 kg of potassium sulfate as base fertilizer. The yield per mu of interplanted sweet potato is 11...

Abstract

The invention discloses a sweet potato and tobacco interplanting method. The method is characterized by comprising the steps of a, ridging and belt forming; b, membrane covering; c, tobacco transplanting; d, sweet potato transplanting; e, field management; f, tobacco leaf harvesting, wherein tobacco leaf harvesting is started at the beginning of July and ends at the end of August; g, sweet potato harvesting, wherein sweet potatoes are harvested at the end of November. According to the method, three-dimensional space of field growth of sweet potatoes and tobacco and crop growth and mature time are fully utilized, the method is especially effective for farming in mountain areas where land resources are limited, economic benefits are obtained through tobacco leaves on the ground, overground stem leaves and underground tubers of sweet potatoes also drive the development of animal husbandry and starch processing industry, and then two crops are harvested on the same land and planting benefits of farmers are increased.

Description

technical field [0001] The invention relates to a method for interplanting sweet potatoes and flue-cured tobacco. Background technique [0002] Sweet potato is a twining herbaceous vine crop of Dioscoreaceae, with a well-developed root system. The underground tubers are the main harvested part, and the stems and leaves on the surface are also edible. [0003] Sweet potato is a high-yielding, stable-yielding, nutritious, and widely used vegetatively propagated crop. It is mainly propagated through stems, tubers, and seedlings. It is also an important food, feed, industrial raw material, and new energy root crop. The total output of sweet potato ranks seventh in the world's food production, and it is widely planted in more than 100 countries in the world. The total output of sweet potato ranks fourth in my country's food crop production, second only to rice, wheat, and corn. 90 million mu, with a total output of about 400 million tons. [0004] Tobacco: An annual herbaceous p...
