Flue-cured tobacco floating breeding nutrition pool capable of protecting cultivated land in greenhouse and building method thereof

Abstract

The invention discloses a flue-cured tobacco floating breeding nutrition pool capable of protecting cultivated land in a greenhouse and a building method thereof. The method sequentially comprises the following flow process that the land in the greenhouse is leveled, a breeding culture nutrition pool is manufactured, a water bed film is paved, water is injected, a nutrition solution and copper sulfate are added, a floating disc after the seedling breeding is put, and subsequent management is carried out. The flue-cured tobacco floating breeding nutrition pool has the advantages that the structure principles are simple, the operation is convenient, and particularly, good ecological, social and economic benefits are realized in Guizhou mountainous areas.

Description

technical field [0001] The invention relates to a flue-cured tobacco floating seedling raising nutrient pool for protecting arable land in a greenhouse and a construction method thereof, belonging to the technical field of tobacco production. Background technique [0002] With the development of the global economy, society, culture and the progress of science and technology, after more than 30 years of reform and development, China has also undergone earth-shaking and profound changes. Compared with other countries, there is still a big gap, especially in the relatively backward areas in western China. The agricultural productivity and people's living standards not only lag behind the advanced developed areas such as the Yangtze River Delta, but also have a larger gap with the developed countries in the world. The gap between developed countries in the world, relying on the achievements made in recent decades, the Chinese government has increased its support for agriculture,...

Problems solved by technology

Since the technology was popularized across the country, it has basically covered all tobacco areas in the country, and the area occupied by seedlings has reached about 60,000 mu. It has made great progress and achievements in promoting flue-cured tobacco seedlings to modernization and factory production. However, the construction of seedling nutrient pools There is no uniform standard on the standard, and there are various construction modes, many of which are seriously destructive to the land in the shed. In order to continuously improve the output rate, corresponding advanced facilities are continuously provided, and at the same time, for the convenience of the staff to carry out Relevant operations, such as cementing the ground in the shed and building various facilities, etc., have greatly damaged the structure of the cultivated layer of the land, and also adversely affected its cultivation. If the situation changes in the future, the original land needs to be restored. That will no longer be arable land and can only be used for other purposes. It is a huge loss for China, which has a lot of people and little land.
