Embodiment 1

[0028] Crush 3kg of rice husk, 3kg of rice chaff, and 4kg of rice straw into a fine powder with a fineness of 5-10mm, add 100kg of 0.5% EM microbial agent and 140g of water to each 500kg of the mixture, store it, and fully decompose and ferment it. Fermentation mixture; then take 4.5kg of fermentation mixture, 2.0kg of perlite, 1.2kg of peat, 0.9kg of humic acid, 0.9kg of hydrophilic agent, and 0.5kg of multi-functional rice seedling conditioning agent, mix and stir evenly, spray clean water to make the raw materials reach extrusion In a state where the film is not loose, under normal circumstances, it is appropriate to have a moisture content of about 15%; stir evenly after batching; transfer the stirred matrix raw material to the tablet press with a conveyor belt, control the thickness of the loose raw material at about 15mm, and extrude The thickness after being sliced ​​is about 5mm; it is sliced ​​according to the specifications of rice seedling raising trays, dried, and t...

Embodiment 2

[0030] 3.5kg of rice husk, 2.5kg of rice chaff, and 4kg of rice straw are crushed into fine powder with a fineness of 5-10mm, and 120kg of 0.4% EM microbial agent and 150kg of water are added to each 500kg of the mixture, and then heaped and stored for fully decomposed and fermented. Make a fermentation mixture; then take 3.5 parts of the fermentation mixture, 2.2 parts of perlite, 1.5 parts of peat, 1.1 parts of humic acid, 1.0 part of hydrophilic agent, and 0.7 parts of multifunctional rice seedling conditioning agent, mix and stir evenly, press, slice, bake Dried to the present invention.

Embodiment 3

[0032] Crush 4kg of rice husk, 3kg of rice chaff, and 34kg of rice straw into a fine powder with a fineness of 5-10mm, add 100kg of 0.3% EM microbial agent and 160kg of water for every 500kg of the mixture, store it, and fully decompose and ferment it. Fermentation mixture; then take 4 parts of fermentation mixture, 2.1 parts of perlite, 1.4 parts of peat, 1.0 part of humic acid, 1.0 part of hydrophilic agent, 0.5 part of multi-functional rice seedling conditioning agent, mix and stir evenly, press tablet, slice, and dry cost invention.

Abstract

The invention provides prefabricated plate type seedbed soil and a preparation method for raising paddy rice seedlings. The preparation method comprises the following steps of: smashing rice hull, blighted grains and straw, mixing according to a certain proportion, adding an EM (Effective Microorganism) microbial agent and water for stockpiling and storing, fully composting, and fermenting to obtain a fermentation mixture; uniformly mixing and stirring the fermentation mixture, perlite, grass carbon, humic acid, a hydrophilizing agent and a multifunctional paddy rice seedling raising conditioner according to the certain proportion, spraying clear water till raw materials are not loosened when extruded into sheets, and stirring uniformly; and extruding into sheets, splicing and drying to obtain the prefabricated plate type seedbed soil. According to the invention, the aims of saving the soil resource, efficiently utilizing resources and maintaining and repairing the weak ecological environment can be fulfilled, high yield, stable yield and sustainable development of paddy rice in cold paddy rice regions, saline and alkaline paddy rice regions and the like are facilitated, and the social benefit, economic benefit and ecological benefit are enhanced.

Description

technical field [0001] The invention provides a prefabricated plate-type bed soil for rice seedling raising, and also discloses a preparation method of the plate-type bed soil, belonging to the technical field of crop cultivation. Background technique [0002] The traditional bed soil preparation technology mainly involves the following two aspects: one is to take soil, the traditional bed soil takes a large amount of soil, and the bed soil is mostly garden soil, vegetable field soil, dry field soil, etc. Heavy use and light cultivation lead to the thinning of the soil plow layer, the decline of soil grade and soil fertility year after year, and it is becoming more and more difficult to meet the demand for soil quality and quantity of nursery beds. Among them, the shortage of nursery bed soil is more serious in cold and saline-alkaline rice areas. The second is the preparation of bed soil. The process is cumbersome and complicated, and it is not easy to master. It involves ...
