Matrix nutrition soil production

Substrate nutrient soil production Organic waste made of dielectric materials should meet certain requirements: First, the total nutrients after fermentation is generally below 4%? N+P2O5+K2O dry basis, if the total nutrients exceed 4% can be included in the organic Fertilizer category. Secondly, the material after fermentation can be basically stable for more than 1 year. Third, after the completion of fermentation, the EC value (conductivity) is below 4 and the water absorption rate is above 2. In addition, raw materials should also be available at a low price. For example, cottonseed husks, pig manure, cow dung, rice hulls, slag ash, sawdust, sawdust, and reed paper mill waste that have been planted with mushrooms are materials that are made into organic ecological cultivation substrates.
However, the organic ecological cultivation medium (matrix) is accompanied by the continuous deepening of environmental awareness, and it has only been proposed in recent decades. It is based on the fermentation of organic waste, especially the addition of functional fermentation bacteria (such as gold Baby-type fermentation aids are treated with a small amount of peat, vermiculite, perlite, and other mineral media, and are made to meet the non-toxic renewable culture medium of modern horticultural production. The key to the development of organic ecological medium cultivation is how to develop a medium (matrix) with stable physical and chemical properties, wide source of raw materials, low cost, no pollution to the environment, and easy production of large-scale commercial products. With the increasing awareness of environmental protection, the problem of post-processing of rock wool has become increasingly prominent. While peat (charcoal) is a non-renewable resource in the short term, overexploitation of peat has been limited; coupled with uneven distribution of peat resources, transportation costs have greatly increased from the northeast of the main producing area to the location of use (the southern part accounts for a considerable proportion). The eyes naturally go to many wastes. The use of various organic wastes to make ecological soilless organic medium not only solves the problem of organic waste disposal, but also provides organic medium for soilless cultivation, improving the comprehensive utilization level of natural resources, ecological and social benefits. The economic benefits have been taken into account. For example, many garden flower units in China are trying to use a strain called Jinbao fermentation auxiliaries. The sawdust bark deciduous and other wastes are fermented into an ecological matrix, which has achieved very good economic results and is being vigorously promoted.
