Substrate for rapidly cultivating seedlings of rice and preparation method thereof

Abstract

The invention relates to the technical field of seedling cultivation substrates of rice, and more specifically relates to a substrate for rapidly cultivating seedlings of rice and a preparation methodthereof. The substrate is prepared by the following components in parts by volume: 40-60 parts of peat, 20-30 parts of perlite, 15-25 parts of vermiculite, 1-5 parts of an organic fertilizer, and 0-5parts of bentonite; and the components are uniformly stirred. The invention provides the substrate for rapidly cultivating seedlings of rice and the preparation method thereof, and available nutrients and long-acting nutrients are combined, porous substances for water retention are added, pH value is adjusted for optimal growth, and other measures are used; the substrate has low cost without environment destroy, soil is not needed, rice seedlings are germinated 3-5 days earlier, seedling age suitable for mechanical transplanting can be realized 5-10 days earlier, seedlings are regular and strong, and roots are well developed.

Description

technical field [0001] The invention relates to the technical field of rice seedling raising substrate, in particular to a rice rapid seedling raising substrate and a preparation method thereof. Background technique [0002] Rice is the main food crop, and the realization of full mechanization is the only way. In recent years, in order to reduce labor costs and improve labor efficiency, machine-transplanted rice seedlings have become the main technology for high-yield grain production technology projects. The first technology to be solved for mechanized rice transplanting is the industrial seedling raising technology, and the core technology of industrial seedling raising is the substrate. [0003] At present, most of the industrial seedling-raising substrate (soil) still stays in the stage of raising seedlings by taking the soil from the cultivated layer of cultivated land and fertilizing the nutrient soil to raise seedlings. There are also problems such as high energy co...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the industrial seedling-raising substrate (soil) still stays in the stage of raising seedlings by taking the soil from the cultivated layer of cultivated land and fertilizing the nutrient soil to raise seedlings. There are also problems such as high energy consumption and difficult transportation; some of them are configured into organic substrates through the fermentation of agricultural waste, but these substrates have problems such as long fermentation time, cumbersome steps, unbalanced or unreasonable nutrients, and high prices.
