Cuttage seedling substrate of stevia rebaudiana and preparation method thereof

Abstract

The invention provides a cuttage seedling substrate of stevia rebaudiana and a preparation method thereof. The seedling substrate comprises, by weight, 25-40 parts of fermentation organic fertilizer,15-30 parts of perlite, 5-15 parts of furnace slag, 0.02-0.1 part of fertilizer and 5-10 parts of water-retaining agent. The cuttage seedling substrate of the stevia rebaudiana is short in seedling period and high in survival rate.

Description

technical field [0001] The invention belongs to the technical field of plant cutting propagation, and in particular relates to a Stevia rebaudiana cutting seedling raising substrate and a preparation method thereof. Background technique [0002] Substrate is the most critical material in seedling cultivation, and it is an important factor in determining the growth environment of stevia roots. In addition to fixing plants, it can also provide nutrients and water for plant production; different substrates have a greater impact on seedling cultivation, and the quality of the substrate is good. Poorness directly affects the success of seedling raising technology; modern solid substrates have been widely used, and it is also common to use straw fermentation to make seedling raising substrates, but most of the substrate raw materials are single, and the physical and chemical properties after fermentation are not ideal; the cutting process of Stevia rebaudiana It requires a lot of ...

[0002] Substrate is the most critical material in seedling cultivation, and it is an important factor in determining the growth environment of stevia roots. In addition to fixing plants, it can also provide nutrients and water for plant production; different substrates have a greater impact on seedling cultivation, and the quality of the substrate is good. Poorness directly affects the success of seedling raising technology; modern solid substrates have been widely used, and it is also common to use straw fermentation to make seedling raising substrates, but most of the substrate raw materials are single, and the physical and chemical properties after fermentation are not ideal; the cutting process of Stevia rebaudiana It needs a lot of water, especially in the later period. Generally, sand or garden soil is used for cutting seedlings, and there are problems such as the substrate does not retain water, is not airtight, and the fertilizer is scarce in the later period.
