Abstract
The invention provides a special charcoal based soilless and organic seedling raising substrate for rice, and belongs to the fields of an agricultural waste recycling technology and a soil fertilizer technology. The special charcoal based soilless and organic seedling raising substrate comprises raw materials in percentage by weight as follows: 20%-60% of charcoal, 10%-50% of organic fertilizer, 10%-40% of a water-retaining agent and 0.1%-0.5% of a root growth promoting agent. According to the special charcoal based soilless and organic seedling raising substrate for rice, the design is reasonable, charcoal is taken as a rice seedling raising carrier, the problems existing in other seedling raising substrates are solved after scientific blending of the charcoal, the organic fertilizer, the water-retaining agent and the root growth promoting agent, and the seedling raising substrate has the advantages that the production process is simple, raw materials are easy to obtain, the cost is low, the seedling raising operation is simple and the like, and has incomparable advantages compared with other substrates.
Description
technical field [0001] The invention belongs to the field of agricultural waste recycling technology and soil fertilizer technology, and in particular relates to a special biochar-based soilless organic seedling raising substrate for rice. Background technique [0002] Rice is an important food crop in my country, and the sustainable and healthy development of the rice industry is an important way to ensure food security in my country. In recent years, my country has made remarkable achievements in the development of rice seedling raising technology, and has formed a supporting technology for cultivating various types of strong seedlings. Industrialized seedling cultivation is currently the most advanced production mode of seedling cultivation. It has been paid more and more attention due to its advantages of energy saving, high production efficiency, good quality of seedlings, fast seedling growth and high survival rate. However, these seedling raising techniques generally...
