Abstract
The invention discloses a rice compound seedling raising substrate, which is composed of the following components in volume percentage: 50-60% of domestic sludge, 20-30% of charcoal ash, and 20% of nutrient soil. A preparation method of the rice compound seedling raising substrate disclosed by the invention comprises the following steps of: dehydrating and drying domestic sludge, sieving domestic sludge till the particle size is 1-4 mm, adding nutrient soil and charcoal ash to mix uniformly, fermenting, and obtaining the rice compound seedling raising substrate. The rice compound seedling raising substrate and the preparation method thereof disclosed by the invention have the advantages that: resources are wide, so that local materials can be realized; organic wastes can be converted and recycled; ecological balance is beneficial to being kept; the rice compound seedling raising substrate disclosed by the invention is subjected to rice seedling raising comparison in a sunlight greenhouse; growth of seedlings is observed; and the seedling raising test results show that the rice compound seedling raising substrate disclosed by the invention is capable of well promoting rice growth.
Description
Technical field
The present invention relates to reclaiming organic waste and utilize technical field, relate in particular to compound seedling medium of a kind of paddy rice and preparation method thereof.
Background technology
Paddy rice is China main food crop, since the eighties year is promoted rice shoot with rsgun and wide planting, has had the time of recent two decades, and huge contribution has been made in the development that this technology is rice cultivating technique and the raising of rice yield.Doing seedling soil because technique adopts vegetable mould and high-quality dry land ground soil, there are a lot of new problems in paddy drought seedling now.Adopt in recent years substrate seedling technology, can not only overcome the above problems, be also beneficial to the demand of the operation of ruleization modelling and modern agriculture.Comprehensive various places seedling matrix material mainly contains: plant ash, vinasse, earthworm excrement, vermiculite, edible fungi residues, perlite, manioc waste.
Rice industrial hole plate seedling growth is that in porous cave dish, to carry out Mechanization sowing, industrial seedling rearing with matrix such as the peat composed of rotten mosses, vermiculite, perlites be a kind of modernization production system of growing seedlings.Use more substrate material to have peat, rock wool, vermiculite, perlite, bagasse, mushroom slag, grit and haydite etc.Rock wool and peat are most widely used general in the whole world at present, are the comparatively ideal cultivation matrixes of generally acknowledging in the world.But along with using in a large number year by year, its negative effect of bringing to society and ecotope also becomes clear day by day, on the one hand due to rock wool non-degradable, a large amount of use brought secondary pollution to environment; On the other hand, peat is non-renewable resource, and excessive exploitation has the danger of exhaustion; Therefore, seek and the good novel cultivation matrix of excavating the pollution row materials such as inexpensive, the alternative rock wool of being easy to get has become one of current researcher study hotspot.In recent years, develop the organic substrates such as coconut fiber, bark, wood sawdust abroad, not only can significantly reduce cultivation cost, and reduce the pollution to environment.China to matrix research start late, " research and development of gathering materials on the spot, suit measures to local conditions " become common recognition.
Along with the quickening of Urbanization in China, treatment rate of domestic sewage improves year by year, and the sludge yield of municipal sewage plant also sharply increases.After mishandling mud entered environment; bring secondary pollution directly can to water body and atmosphere; municipal sewage plant, a sludge treatment just can not be given full play to the effect of its decontamination protection of the environment, also will form serious threat to ecotope and mankind's activity simultaneously.It is estimated, the sludge quantity (dry weight) of the annual discharge in municipal sewage plant of China is at present approximately 1,300,000 tons, and annual growth is greater than 10%, particularly, in Chinese Urbanization level higher several cities and area, mud problem of outlet is very outstanding.If municipal effluent is all processed, will produce sludge quantity (dry weight) is 8,400,000 tons, accounts for 3.2% of China's total solids waste.
The patent No.: 201310402763 have introduced the full nutrition rice seedling medium preparation take the peat composed of rotten mosses as major ingredient; The patent No.: 201210460354 vinasse, Nutrition Soil, vermiculite mix makes compound rice seedling raising ground substance; The patent No.: 201210159785 earthworm excrement, mix and make novel organic substrate with addition of Nutrition Soil, vermiculite.
Comprehensive various places rice nursery substrate material is concluded to be had: plant ash, vinasse, earthworm excrement, vermiculite, edible fungi residues, perlite, manioc waste.Although these sources are abundanter, can not meet the demand of seedling cultivation of rice fast development completely.
Summary of the invention
For obtaining the more rice nursery substrate material of horn of plenty, obtain rice nursery substrate resource material widely, organic waste trans-utilization, preserves the ecological environment.The invention provides compound seedling medium of a kind of paddy rice and preparation method thereof.
The technical scheme that the present invention takes is:
The volume percent of the compound seedling medium of paddy rice of the present invention consists of: domestic sludge 50-60%, charcoal ash 20-30% and Nutrition Soil 20%.
As one of preferred technical scheme: the volume percent of the compound seedling medium of paddy rice of the present invention consists of: domestic sludge 50%, charcoal ash 30% and Nutrition Soil 20%.
As one of preferred technical scheme: the volume percent of the compound seedling medium of paddy rice of the present invention consists of: domestic sludge 60%, charcoal ash 20% and Nutrition Soil 20%.
As one of preferred technical scheme: the volume percent of the compound seedling medium of paddy rice of the present invention consists of: domestic sludge 55%, charcoal ash 25% and Nutrition Soil 20%.
Domestic sludge is the solid precipitation material being produced by water and sewage treatment process.
The powder forming after the straw burning of Tan Huishi power plant.
The method of preparing the compound seedling medium of paddy rice of the present invention is as follows: domestic sludge is dehydrated and is screened into 1-4mm particle diameter, then mix with addition of Nutrition Soil, charcoal ash, after fermentation acid adjustment, make compound rice seedling raising ground substance.
The particle diameter of charcoal ash and Nutrition Soil is 3-5mm.
Positively effect of the present invention is as follows:
The present invention has the following advantages: 1, resource is extensive, can realize the matter of gathering materials on the spot; 2, organic waste can transform recycling; 3, favourable keeping ecological balance.
The compound seedling medium of paddy rice of the present invention carries out seedling cultivation of rice comparison in heliogreenhouse, observes seedling growth.The compound seedling medium of seedling growth test result surface paddy rice of the present invention can better promote paddy growth.
