Abstract

The invention relates to a stevia rebaudiana seedling medium for the cultivation of agricultural vegetables and flowers and a preparation method thereof, comprising the following raw materials in parts by weight: 0.5-5 parts of stevia rebaudiana stem, 90-98 parts of turf, and 1-5 parts of leech. The preparation method comprises the following steps: adding the smashed stevia rebaudiana stem, turf powder and leech, mixing uniformly, disinfecting and sterilizing at high temperature so as to prepare the stevia rebaudiana seedling medium. The invention has the following advantages: the seedling medium can provide enough organic nutrient content for the seedling emergence of seeds, thereby promoting the growth of root and restraining root rot and fusarium wilt.

Description

technical field [0001] The invention relates to a raw material formula of a seedling-raising substrate used in the breeding of agricultural vegetables and flower seedlings and a preparation method thereof. Background technique [0002] In my country, horticulture and vegetable crop seedling breeding are divided into two forms: industrial seedling raising and independent seedling raising by farmers one by one. The seedling substrates used in industrial seedling cultivation are mainly imported peat. These imported seedling substrates are mainly peat and vermiculite with trace elements added, which are expensive and the cost of seedling cultivation is relatively high. Most of the farmers who raise seedlings one by one use garden soil plus farmyard manure plus some fungicides and insecticides. Due to the lack of preparation experience of farmers who adopt the method of raising seedlings one by one, the farmyard manure cannot be fully decomposed, resulting in burning seedlings, ...
