Abstract
The invention discloses a rice seedling raising medium which comprises the following raw materials in parts by weight: 60-80 parts of bagasse pith, 20-40 parts of mud, 0.01-0.03 part of microbial agents, 3-5 parts of a fertilizer slow-release agent and 40-55 parts of a water retaining agent, wherein the water retaining agent is vermiculite; and the fertilizer slow-release agent consists of ferrous sulfate heptahydrate, urea and water in a mass ratio of 3:2:20. The invention further discloses a preparation method of the rice seedling raising medium. A part with non-fiber parenchymal cell myelocyte screened from bagasse pith, namely bagasse paper or artificial fiber plates is adopted as a main raw material, the raw material is fermented with beneficial microorganisms, the fertilizer slow-release agent, the water retaining agent and the like are mixed to prepare the rice seedling raising medium, the rice seedling raising medium has long-lasting fertility and good water retention and air permeability properties, and nutrition requirements of rice in a seedling period can be met in balance for a long time.
Description
technical field [0001] The invention relates to industrial seedling raising, more specifically a rice seedling raising substrate and a manufacturing method thereof. Background technique [0002] Rice is the largest grain crop in Guangxi, with an annual planting area of more than 30 million mu, accounting for about 60% of the grain planting area. Because our region is a hilly area with complex terrain, and rice planting is affected by many factors such as climate conditions, geographical environment, farming system, agricultural machinery industry, economic conditions, etc., the methods of planting rice in various places are different, which leads to the rice production in our region. The development of mechanization is slow, and the production method is still relatively traditional. At present, the mechanization level of rice production in the whole region has exceeded 70%, but the two links of rice seedling raising and transplanting are relatively weak. [0003] In rece...
