Soilless organic ecological environmentally-friendly seedling raising matrix for paddy rice, seedling raising method for paddy rice and production method for matrix

Abstract

The invention belongs to the technical field of crop seedling raising and discloses a soilless organic ecological environmentally-friendly seedling raising matrix for paddy rice, a seedling raising method for the paddy rice and a production method for the matrix. A woody fiber is one or a mixture of more than one of woody fibers in crop straws such as rice hulls, rice straws, wheat straws, corn straws, cotton straws, peanut hulls and the like or other plant straws; a binder is a natural organic binder; a water-retaining agent is a natural organic water-retaining agent; organic fertilizer is bio-organic fertilizer; the usage amount of the crop straws is 200.0-400.0g / plate; the usage amount of the binder is 0.3-0.5g / plate; the usage amount of the water-retaining agent is 3.0-6.0g / plate; and the usage amount of the organic fertilizer is 1.5-2.5g / plate. According to the soilless organic ecological environmentally-friendly seedling raising matrix for the paddy rice, the seedling raising method for the paddy rice and the production method for the matrix, the matrix has relatively good water-absorbable and swellable properties and sufficient nutrient supply capability; and the raised seedlings are high in quality, good in mat formation property, strong in stress resistance and quick in greening after transplantation.

Description

technical field [0001] The invention relates to a soilless organic ecological environment-friendly substrate and a production method thereof, in particular to a soilless organic ecological environment-friendly seedling raising substrate for rice, a seedling raising method and a production method thereof, and belongs to the technical field of crop seedling raising. Background technique [0002] Traditional rice machine-transplanted seedlings are mainly based on field soil or nutrient soil. The common seedling tray specifications are 58 cm long, 28 cm wide, and 2.5 cm high. With such a seedling tray, the average amount of field soil or nutrient required for machine-transplanted seedlings per acre is The soil is about 80 kg. At present, machine-transplanted rice mainly adopts soil seedling raising and transplanting with soil. The nutrient soil required is all taken from farmland or forest land plow layer. A large amount of soil is taken every year and seriously damages the plow...

Problems solved by technology

The addition of chemical raw materials increases the production cost of the substrate to a certain extent, and also has a certain negative impact on the surrounding ecological environment; the polymer chemical substances are transplanted into the paddy field soil with the seedlings, and their degradation cycle in the soil is slow, and the degradation residues are easy to Farmland soil causes secondary pollution; sources of raw materials such as peat are non-renewable
