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.
