The invention belongs to the technical field of nutrient soil, and particularly discloses a preparing method of nutrient soil for improving the content of antioxidant activity substances in a cactus.The method specifically includes the following steps of firstly, weighing raw materials; secondly, smashing corncobs, conducting steam processing, taking out the smashed corncobs for refrigerating processing and steam processing, evenly mixing the processed corncobs with molasses, conducting slow-fire boiling and continuous stirring, evenly mixing the mixed material with red jade soil, and conducting fermenting to obtain a fermented material; thirdly, conducting homogenizing processing and microwave drying on the fermented material, and evenly mixing the fermented material with almond shell powder, willow bark powder, activated vermiculite powder, grape seed extracts and ginkgo leaf extracts to obtain the nutrient soil for improving the content of the antioxidant activity substances in thecactus. The sprouting and seedling emerging rate and the seedling strengthening index of the cactus are effectively increased, the splitting, differentiating and growing of root systems are promoted,the root rotting phenomenon can be effectively avoided, maintaining is easy, the content of flavones, polyphenols, polysaccharides and other antioxidant activity substances in the cactus is effectively increased, and the edible value and medicinal value of the cactus are greatly improved.

The invention relates to the field of seedling raising, and discloses a composition for a seedling substrate, the seedling substrate, a preparation method thereof and the application in rice seedlingraising. The preparation method of the seedling substrate includes conducting mixing, heat treatment and cooling on the following materials by mass: 3%-20% of grass carbon, 15%-30% of rice husk ash, 5%-15% of vermiculite, 5%-15% of clay, 5%-10% of fly ash, 20%-40% of straw-based edible fungus residue and 5%-25% of organic fertilizer. The straw-based edible fungus residue is selected as the main raw material of the rice seedling substrate. The seedling substrate composed of the straw-based edible fungus residue and an organic fertilizer in specific ratio can effectively increase the biomass, the root activity, the fullness and the seedling index of seedlings. Moreover, the plant height and the stem diameter of the seedlings obtained are both ideal, and the growth rate is high.

The invention provides a cultivation method for healthy color pepper seedlings. A seedling cultivation substrate is prepared by evenly mixing cordyceps fungus fementation rich in cordyceps mycelia, peat, vermiculite and perlite according to the volume ratio 1:5:2:2, and plug seedling is performed; when color peppers are germinated until cotyledons are spread, each plant is irrigated with 5-8 ml of potassium phosphate water solutions with the concentration of 30 mg / kg-1; when a first heart leaf is mudded until one leaf and one heartleaf are grown, each plant is irrigated with 8-10 ml of prohexadione calcium water solutions with the concentration of 20 mg / kg-1; when two leaves and one heart leaf are grown, each plant is irrigated with 12-15 ml of dufulin water solutions with the concentration of 100 mg / kg-1; when three leaves and one hear leaf are grown, each plant is irrigated with 12-15 ml of potassium phosphate water solutions with the concentration of 75 mg / kg-1. The seedlings cultivated through the cultivation method are superior to those cultivated through conventional plug seedling in the aspects such as root activity, strong seeding index, flower mud differentiation, disease resistance, yield and the like.
