Seedling culture substrate for improving seedling survival rate and preparation method thereof

Abstract

The invention discloses a seedling culture substrate for improving the seedling survival rate. The substrate is prepared from the following ingredients in parts by weight: 18 to 26 parts of humus soil, 8 to 17 parts of bran coat, 6 to 45 parts of turf, 1 to 5 parts of organic fertilizers, 25 to 45 parts of waste fungus rods and 2 to 5 parts of activation powder. The invention also discloses a preparation method of the substrate. The seedling culture substrate can be used for culturing high-quality seedlings; the adaptability of the seedlings is high; the disease and insect pest resistance of the seedlings is relatively improved; the survival rate is high; meanwhile, the soil structure is effectively improved; the soil microbes are activated; the soil fertility is increased; the soil water absorption and soil moisture preservation capability can be improved; the soil aggregate formation is promoted; the rainfall anti-erosion capability of soil is improved.

Description

technical field [0001] The invention relates to a seedling-raising substrate, in particular to a seedling-raising substrate for improving the survival rate of seedlings and a preparation method thereof. Background technique [0002] Industrialized seedlings are gradually accepted by many people of insight in agriculture, which greatly promotes the research on the application of seedling substrates. The most commonly used substrate materials are peat, rock wool, vermiculite, perlite, bagasse, mushroom residue, gravel and ceramsite. At present, rock wool and peat are the most widely used in the world, and are recognized as ideal cultivation substrates in the world. However, with the large-scale use year by year, its negative effects on society and the ecological environment are becoming more and more obvious. On the one hand, because rock wool is not degradable, extensive use will cause secondary pollution to the environment; on the other hand, peat is a non-renewable resourc...
