New medium for floating seedling raising of flue-cured tobacco

Abstract

The invention discloses a new medium for floating seedling raising of flue-cured tobacco, and relates to the flue-cured tobacco growing technology in the technical field of agriculture. The new medium is prepared by mixing 10 to 30 volume parts of peat, 30 to 50 volume parts of carbonized chaff, 10 to 30 volume parts of expanded pearlite and 20 to 30 volume parts of river sand. The new medium has the characteristics of reducing the influence on ecological environment, reducing production cost of the flue-cured tobacco and the like, and is suitable for floating seedling raising of flue-cured tobacco in flue-cured tobacco growing regions across the country.

Description

technical field The invention relates to flue-cured tobacco planting technology in the field of agricultural technology, in particular to a novel substrate for floating seedling cultivation of flue-cured tobacco. Background technique Floating seedling cultivation is a tobacco seedling cultivation technology commonly used in the current flue-cured tobacco planting technology, especially in today's rapid development of modern agriculture, its application is becoming more and more common. In the prior art, the substrate used in flue-cured tobacco floating seedlings is peat as the main raw material, and its proportion is very high. Therefore, it will consume a large amount of peat, a non-renewable earth resource, destroy the ecological environment, and harm the natural environment. Resources have an irreversible impact and, at the same time, higher production costs due to the higher price of peat. Contents of the invention Aiming at the deficiencies in the prior art, the tec...
