Problems solved by technology

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 resource. , Excessive mining has the risk of depletion; therefore, seeking and discovering good new cultivation substrates that are easy to obtain and cheap, and can replace polluted materials such as rock wool has become one of the hotspots of current scientific researchers.

Abstract

The invention discloses a composite seedling growing substrate for paddy rice and a preparation method thereof. The method comprises the following steps: (1) mixing alcohol residue with domestic sludge, then adding a fermentation inoculum, carrying out aerobic fermentation at high temperature, then carrying out crushing and drying, adding nutrient soil and charcoal ash and carrying out uniform mixing so as to prepare organic fertilizer; and (2) separately crushing the organic fertilizer and inorganic fertilizer and carrying out mechanical uniform mixing so as to prepare the composite seedling growing substrate for paddy rice. The prepared composite seedling growing substrate for paddy rice comprises, by volume, 20 to 30% of alcohol residue, 20 to 30% of domestic sludge, 10 to 15% of charcoal ash, 25 to 30% of nutrient soil and 5 to 15% of inorganic fertilizer. With the preparation method, more abundant seedling growing substrates for paddy rice can be obtained under the condition of no increase of cost, wider seedling growing substrate resource materials are obtained, organic waste is converted and utilized, and ecological environment is protected.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a rice composite seedling-raising substrate and a preparation method thereof. Background technique [0002] Rice is the main food crop in my country. It has been nearly 20 years since the popularization of rice dry breeding and sparse planting in the 1980s. This technology has made great contributions to the development of rice cultivation technology and the increase of rice yield. Because this technology uses humus soil and high-quality dry field soil as seedling soil, many new problems have appeared in rice seedling raising. In recent years, the use of matrix seedling cultivation technology can not only solve the above problems, but also benefit the needs of large-scale operation and modern agriculture. The substrate materials for seedling cultivation in various places mainly include: grass ash, distiller's grains, vermicompost, vermiculite, edible fungus residue, perlite,...
