Embodiment 1

[0021] A light substrate for raising seedlings, the mass percentage of ingredients is: 40% of power plant ash, 30% of peat, 10% of organic fertilizer, 10% of straw and 10% of vermiculite. The above components are mixed as the base, and 5 grams of urea is added per kilogram. The production method is as follows: spray 40% sulfuric acid aqueous solution while stirring the power plant ash in a mixer, and adjust the pH value to reach between 5-6.5. After mixing the modified power plant ash with peat, organic fertilizer, straw and vermiculite according to the above ratio, spray carbendazim aqueous solution while stirring in the mixer, and use carbendazim with a purity of 80% per cubic meter Powder 100-200 mg. The matrix is ​​sieved, packed into bags, weighed and packaged.

Embodiment 2

[0023] A light substrate for raising seedlings, the mass percentage of ingredients is: 30% of biomass power plant ash, 30% of organic fertilizer, 30% of rice husk, and 10% of vermiculite. The above components are mixed as the base, and 5 grams of urea is added per kilogram. Its production method is basically the same as that of Example 1, but it does not need to be sterilized.

Embodiment 3

[0025] A light substrate for raising seedlings, the mass percentage of ingredients is: 50% of power plant ash, 20% of organic fertilizer, 10% of rice husk, and 20% of vermiculite. After mixing the above components, add 10 grams of urea per kilogram. Its production method is identical with embodiment two.

[0026] Below is a group of contrastive tests, with peat, perlite volume ratio is 1: 1 matrix as control group, experimental group has used the seedling raising matrix of the present invention, test material is Robinia pseudoacacia, test quantity is 1000 bowls.

Abstract

The invention discloses a light seedling raising medium and a manufacturing method. The main ingredients of the light seedling raising medium comprises 10 to 60 mass percent of biomass power plant ash, 0 to 30 mass percent of grass carbon, 0 to 30 mass percent of organic fertilizer, 0 to 30 mass percent of rice hull or straw and 5 to 20 percent of vermiculite. The ingredients are mixed and used as a base material and each kilogram of the base material is added with 5 to 10 grams of urea or fertilizer. The biomass power plant ash is modified by a pH regulator till the pH value is 5 to 6.5, and the power plant ash, grass carbon, organic fertilizer and straw are mixed in a ratio, stirred, sterilized and fermented to obtain the light seedling raising medium. The medium is low in price, rich in nutrients, simple and convenient in operation and suitable for the industrial seedling raising of forest wood such as robiniapseudoacacia, alder, liquidambar formosana hance, aleurites fordii and camellia oleifera abel.

Description

technical field [0001] The invention belongs to the technical field of substrate seedling raising and cultivation, and is particularly suitable for industrialized light substrate seedling raising. Background technique [0002] Before the present invention was proposed, the solid light matrix seedlings used for industrial production generally used peat (peat), vermiculite, perlite, coconut bran, rice husk, straw, cottonseed hull, etc. as main raw materials, and were fermented, sterilized, packed obtained after the bag. The price of the above-mentioned raw materials is high or the source is limited, the cost of factory production is high and the sterilization is not complete, and most of the raw materials are insufficient in nutrients, which may easily cause defertilization in the later stage of seedling cultivation. The use of biomass power plant ash (plant ash) as the main raw material for substrate seedling cultivation has not been reported yet. Plant ash is mostly used to...
