Abstract

The invention relates to a modifying agent of acidity and cadmium-contaminated soil for planting tobaccos. The modifying agent is characterized in that sepiolite powder and tobacco stem bio-organic fertilizer are mixed according to a mass ratio being 1: (8-10) and are fully stirred, so that the mixture is uniform; the application amount of the modifying agent is 70kg-100kg / mu; and during ridging in tobacco fields, the modifying agent of the acidity and cadmium-contaminated soil for planting the tobaccos serves as base fertilizer to be applied or serves as additional fertilizer to be applied along with potassic fertilizer. The modifying agent has the beneficial effect that the modifying agent of the soil for planting the tobaccos, which is suitable for improvement and prevention of the acidity soil for planting the tobaccos and management of the heavy metal cadmium-contaminated soil, is obtained by organically combining the alkalinity, adsorbability, water-retaining property and other performances of sepiolite and performances of the tobacco stem bio-organic fertilizer such as soil hardening improvement, rhizospheric microorganism community increasing and soil nutrient improvement.

Description

technical field [0001] The invention relates to an improving agent for planting tobacco in acidic and cadmium polluted soil. Background technique [0002] Soil is the basis for crop growth, and good soil quality is the prerequisite for producing high-quality tobacco leaves. Soil acidification will significantly affect the activities of microorganisms in the soil, the synthesis and decomposition of organic matter, the transformation and release of nutrient elements, the availability of trace elements, and the ability of the soil to retain nutrients, etc., thus affecting the improvement of soil production performance and the growth of tobacco development. Almost all nutrient fixation and activation in the soil are related to the soil pH value. On the one hand, too acidic tobacco planting soil is not conducive to the growth of tobacco roots and nutrient absorption, and at the same time affects the availability of soil nutrients. The production of high-quality tobacco leaves r...
