Organic rice seedling cultivation nutrient soil and preparation method thereof

Abstract

The invention relates to organic rice seedling cultivation nutrient soil and a preparation method thereof. Rice seedling cultivation nutrient soil which both meets organic production requirements and is beneficial to cultivation of strong rice seedlings is not available yet at present. The organic rice seedling cultivation nutrient soil comprises organic soil, neutral-position grass carbon, organic rice straw and wood vinegar according to the weight ratio of 60:25:14.7:0.3. The preparation method comprises the following steps: A, selecting a compost preparation site in an organic production unit; B, crushing the organic rice straw into powder, sufficiently mixing with the organic soil and the neutral-position grass carbon according to a ratio, adding water in the mixing process till the components are sufficiently wetted, and performing composting after the components are mixed; C, opening the compost to dry in sunshine till being loose and wet, and screening off stone and impurities by using a sieve of 5-6 meshes; D, diluting the wood vinegar for 10-20 times 1-2 days before application, uniformly mixing the wood vinegar with the nutrient soil, sterilizing the nutrient soil, and adjusting the pH value of the nutrient soil. The organic rice seedling cultivation nutrient soil is capable of meeting organic production requirements and is beneficial to cultivation of strong rice seedlings.

Description

technical field [0001] The invention relates to an organic rice seedling raising nutrient soil and a preparation method thereof. Background technique [0002] Organic rice follows the principles of organic agricultural production, does not use chemically synthesized pesticides, fertilizers, growth regulators and other substances in production, and does not use organisms and their products obtained by genetic engineering. Continuous agricultural technology, a rice production method to maintain the stability of the rice field production system. Rice products marked as organic must comply with the national standard GB / T 19630 "Organic Products", and be certified by a qualified certification body and obtain an organic product certification certificate in accordance with the national organic product "Certification Implementation Rules" and other regulations. [0003] One of the fundamental differences between organic rice and conventional rice is that chemically synthesized pest...
