Abstract

A novel flue-cured tobacco moisture seedling substrate comprises 40% carbonized rice husks, 30% fermented rice husks and 30% loess by volume. A preparation method of the substrate comprises the following steps: (1) adding water and uniformly stirring to prepare a material to be fermented after the rice husks are crushed; (2) uniformly mixing according to the weight ratio of the material to be fermented to urea of 50: 1; (3) mixing according to the weight ratio of the material to be fermented, an HM bacterial decomposition agent, rape seed cakes and rice bran of 1000: 0.2: 15: 20 to fully ferment so as to prepare fermented rice husks; (4) preparing the seedling substrate from 40% carbonized rice husks, 30% fermented rice husks and 30% loess by volume. The invention aims to provide the novel flue-cured tobacco moisture seedling substrate of which shape is difficult to destroy, the pH value is appropriate, the porosity is better, the permeability, the water retain and the nutrient-preserving capabilities are better, as well as the preparation method of the substrate.

Description

technical field

[0001] The invention relates to a flue-cured tobacco moist seedling raising substrate and a preparation method thereof. Background technique

[0002] Flue-cured tobacco floating seedlings and wet seedlings are currently the commonly used seedling raising methods in my country's tobacco areas. Most of the seedling raising substrates are peat soil (peat soil) rich in organic matter and mineral nutrients, with an appropriate proportion of hydrophobic and breathable light materials such as vermiculite. , expanded perlite, etc., while peat soil (peat soil) comes from the swamp wetland environment and is a very important non-renewable natural resource with a limited total reserve. Excessive mining will inevitably cause irreversible damage to the wetland environment in my country. There may also be a shortage of raw materials for seedling raising substrates. Therefore, my country has limited the exploitation of peat soil (peat soil) to a reasonable range. Many resear...
