[background technology]
Rice in Guangxi province entire mechanization is produced and is in a starting stage, and industrial sprout cultivation also just rises, and the sustainable supply of seedling raising ground substance is the prerequisite of greatly developing industrial sprout cultivation. In recent years about the impact of rice growth and output still mainly concentrate on that artificial hand is inserted, on rice transplanting, the planting type such as live, research about machine-transplanted rice is also very few, this research topic is first for the problem that it is difficult that seedling is fetched earth, and the sustainable seedling raising ground substance of localization of rice transplanting mode is educated in the applicable localities of raw material exploration research and development such as originate by Guangxi abundant filter mud of sugarcane, manioc waste, bacterium chaff.
The seedling raising ground substance that the upper existing seedling-cultivation technique of production at present adopts is still taking Nutrition Soil as main. If the area ratio of non-irrigated seedling field and transplant field is 1: 100, non-irrigated seedling field needs soil with 24kg/m2Calculate, the area of rice in Guangxi province transplanting in 2012 has developed into 26.4 ten thousand hectares, need so to take away the topsoil soils of nearly 0.32 ten thousand hectare of arable land 20cm, the problem that it is difficult that raising rice seedlings fetches earth becomes increasingly conspicuous, and the destruction that therefore topsoil soils is subject to can be increasing along with increasing sharply of machine transplanting of rice area. Therefore, for the problem that it is difficult that seedling is fetched earth, the pre-raw materials such as abundant filter mud of sugarcane, manioc waste, bacterium chaff of originating by Guangxi of this research mix in certain proportion with paddy soils, explore the applicable locality of research and development and educate the sustainable seedling raising ground substance of localization of rice transplanting mode, to meet in a large number the needs of Rice Cropping rich and influential family and seedling factory.
Show according to the data of Guangxi statistics bureau, 2012, Guangxi cassava cultivated area had 231.2 thousand hectares, and output reaches 181.31 ten thousand tons. General Alcohol Plant can produce the industrial alcohol of a ton 95% with 7～8 tons of cassavas, can produce the wet manioc waste of 10 tons of left and right, and the pH value of manioc waste after Composting treatment is about 4.0～5.0, is acidity, can reach the requirement of rice shoot to weakly acidic condition. 10,000 tons of sugarcanes of every squeezing, obtain 300～500 tons of wet filter muds, 2012 years, Guangxi sugarcane acreage is 1128.0 thousand hectares, sugarcane yield reaches 7829.71 ten thousand tons, can produce approximately 234.89～391.49 ten thousand tons of wet filter muds, and nutrient in filter mud can meet the requirement of rice shoot to nutrient. Taking filter mud of sugarcane and manioc waste as primary raw material, by mixing in certain proportion development and production rice seedling raising ground substance with paddy soils, there is feasibility and sustainability.
[summary of the invention]
Educate the shortcoming of existence for traditional machine-transplanted rice seedling, the invention provides a kind of matrix of applicable rice mechanization seedling-cultivation plate. This seedling raising ground substance comprehensive nutrition, is particularly suitable for double cropping of rice mechanization seedling, paddy seeds is emerged and take root soon, and planting percent is high, rice shoot is healthy and strong, and disease and pest obviously reduces, and can effectively improve output.

Preferably, the water content of paddy soils is less than 10%.
The preparation process of this seedling raising ground substance is: first by filter mud of sugarcane, manioc waste, bacterium chaff, fertilizer respectively stack retting become thoroughly decomposed, then cross after 40 eye mesh screens for subsequent use, after paddy soils is air-dry, pulverized after 40 eye mesh screens for subsequent usely, by volume umber measures above each raw material, mixes and get final product.
Fertilizer is prepared from by the raw material of following percentage by weight: chicken manure 25%, pig manure 32%, silkworm faeces 15%, plant ash 15%, stalk 10%, EM bacterium stoste 3%; Preparation method is: powder of straw is broken into the powder that is less than 0.5cm, fully mix with chicken manure, pig manure, silkworm faeces, plant ash, by 5 times of EM bacterium stoste dilutions, with the EM bacterium liquid sprinkling after dilution, make mixed raw material moisture reach 30～40%, cock, cover film insulation, ferment 20 days, dry and get final product.
Bacterium chaff, is to utilize the raw material such as stalk, wood chip to carry out edible mushroom substituting stuff cultivation, and the culture medium residue after results, is commonly called as edible fungus culturing waste material, bacterium slag or clout; The residual body of hypha of edible fungus and through edible mushroom enzymolysis, the compound of the compositions such as the crude fibre of structure generation qualitative change. Cultivating the bacterium chaff of edible mushroom, is good organic fertilizer, and Japanese is described as " super compost " for a long time. Because the contained infusibility macromolecular compound of the agricultural byproducts such as stalk is decomposed and becomes simple solable matter by mycelium, thereby can effectively improve the nutrient being absorbed by crops. According to surveying and determination, the discarded compost content of organic matter after foster mushroom, up to more than 30%, is 3 times of straw directly returning to field, and nitrogen content 1.5～1.8%, higher than freshly-slaughtered poultry excrement. Utilize these discarded objects, by microbial fermentation technology, be processed into a kind of Multifunction biological organic fertilizer, not only there are obvious economic benefits, also there is obvious ecology and environmental protection effect.
