Sweet potato and tobacco interplanting method

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...

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
