Environment-friendly degradable rice tray-free seedling raising technology

Abstract

The invention discloses an environment-friendly degradable rice diskless seedling raising technology which comprises the following steps: laying a layer of perforated kraft paper on a seedbed, then laying a layer of plant fiber non-woven fabric on the kraft paper, then laying a seedling raising substrate with the thickness of 2.5 cm on the plant fibers, then sowing rice seeds soaked with coatings on the seedling raising substrate, and then performing seedling raising on the rice seeds. After sowing is completed, a layer of seedling raising substrate with the thickness of 0.5 cm is covered, and then watering is conducted till thorough watering is achieved; when the rice grows to be transplanted, cutting the rice by a cutting machine according to the size of a rice transplanter, rolling the rice seedlings after cutting, and then conveying the rice seedlings to the field for transplanting. The plant fiber non-woven fabric has the effects of heat preservation, moisture preservation, water retention, fertilizer retention, disease resistance, root packing, root fixing and no seedling scattering during transplanting transportation, the mechanical transplanting efficiency and quality are comprehensively improved, and the labor intensity is reduced. The method has the advantages of early insertion, fast germination, no gap filling of seedlings, fast green turning, increase of both production and income, and reduction of farmer capital investment.

Description

Technical field [0001] The present invention involves the field of rice seedlings, and it is more specifically involving an environmentally -protected rice seedlings without breeding technology. Background technique [0002] With the transfer of rural labor, artificial seedlings of rice can no longer meet the requirements of my country's social and economic development. Traditional rice -based rice -based rice -based technology has low technology production efficiency, low labor productivity, and low labor intensity restricting the development of rice production. In production, it is urgent to save labor, save effort, high -yield, and efficient modern rice production technology with mechanization operations, especially rice machine seedlings. In recent years, under the support of the policy, my country's rice machine transplanting technology has developed rapidly, and the proportion of rice mechanized planting has increased from 4.4 % in 2000 to 28 % in 2012. However, the key to ...

Problems solved by technology

However, the key to the success or failure of machine-transplanted rice is the seedlings. At present, the main method of raising rice for machine-transplanted rice in my country is to use standardized seedling trays for tray cultivation, and there are also some trayless seedlings.

[0003] Rice machine-transplanted seedlings mainly use standardized seedling trays as supports for seedling raising. The cost of seedling trays is high, resulting in a large investment in machine-transplanted seedlings. At the same time, most of the seedling trays use plastic as raw materials. Pollution

At present, discless seedling raising mainly uses materials such as woven cloth or film for interlayer seedling raising. Although it solves the problem that the roots of the seedlings penetrate into the deep soil and it is inconvenient to take seedlings, there are interlayers that block the air between the seedling carrier and the lower soil.
