Description
Technical field
The present invention relates to technical field of agricultural cultivation, be specifically related to soilless raising seedling substrate, more specifically relate to a kind of paddy rice culture medium and preparation method thereof.
Background technology
Paddy rice (formal name used at school: Oryza sativa) is the one of draft Oryza, also be the longest main one as grain in Oryza, paddy rice originates in Tropical Asian, after China widely plants, propagate into all over the world gradually, paddy rice institute knot reality and paddy, claim rice, scented rice, rice after paddy (grain) shells.Nearly half population in the world, mainly the Northeast, the Yangtze valley, China paddy rice main producing region, Pearl River Delta, belong to direct economy crop, still 1/3rd mankind are food with rice in the world, and the eating method of rice is varied, there are rice, congee, rice cake, rice cake, rice wine etc.; Paddy rice is except edible, and rice husk, rice straw, can as feed, or the important source material of the industry such as wine brewing, sugaring, food-processing, fuel, and therefore, the plantation of paddy rice gets most of the attention with its importance of development.
Along with developing rapidly of Rice Cropping technology, cultivation technique without soil and seeding raising technology obtain big area, apply on a large scale, the demand of soilless raising seedling substrate increases day by day, the selection of culture medium for seedling and compounding process are important contents, use rock wool in the past, the peat composed of rotten mosses is as the raw material of the culture medium the most often adopted in soilless culture, but cost is high, in recent years, along with the mankind are to the understanding of the importance of sustainable development and environment protection, in the selection of base starting material, the peat composed of rotten mosses is replaced by reproducible agricultural organic waste resource, rock wool etc., become the megatrend of world development, the raw material of this kind of matrix has renewable, to originate wide advantage, its nutritive ingredient is high, tooling cost is low, easy to use, at present, China rural area also have considerable part place still with vegetable fibres such as Caulis Sacchari sinensis leaf, straw, corn stalk, branches for main fuel, these fuel can produce more lime-ash after combustion, Guangxi is the large province of cane planting, also be produce the large province of sugar, can produce many bagasses after sugar refinery squeezing sucrose, and these bagasses can produce a large amount of lime-ash after burning, containing a large amount of nutritive elements useful to farm crop in lime-ash, if well utilized, while raising waste utilization, also while being the production system that economizes on resources of reserved resource and environment, foundation, agriculture nuisanceless standardized production, the implantation methods of research non-pollution rice, the important channel that constantly promotes agricultural industry level, enhance one's market competitiveness is strengthened, also be that the enhancement both urban and rural residents is healthy, realize economic benefit, ecological benefits and social benefit, promote the important channel of national economy and social sustainable development.
Summary of the invention:
The object of this reality invention is: for above-mentioned Problems existing provide a kind of nutritive ingredient high, be easy to the paddy rice culture medium and preparation method thereof processed, the object that this reality is invented, for solving the problem, is realized by following technical measures,
