Soil improvement and root inducing type enzyme carbon-based functional fertilizer for continuous cropping tobaccos and application method thereof

Abstract

The invention relates to soil improvement and root inducing type enzyme carbon-based functional fertilizer for continuous cropping tobaccos and an application method thereof and belongs to the technical field of agricultural resource development. The soil improvement and root inducing type enzyme carbon-based functional fertilizer for the continuous cropping tobaccos is prepared from the followingcomponents in percentage by weight: 45 to 50 percent of distillers' grain biological carbon, 40 to 48 percent of a composted material, 5 to 10 percent of seaweed meal, 0.5 to 1 percent of enzyme bacteria, 0.5 to 1 percent of bacillus amyloliquefaciens and 0.05 to 0.1 percent of compound sodium nitrophenolate. The soil improvement and root inducing type enzyme carbon-based functional fertilizer isprepared by matching natural components, has abundant bioactive substances, also has the effects of improving a soil physical structure in situ, increasing water retention and fertilizer retention capability of soil, reducing gas emission of a large field greenhouse and promoting early and rapid growth of crops and has a stable continuous cropping resisting effect. The soil improvement and root inducing type enzyme carbon-based functional fertilizer can be widely applied to crops including tobaccos, fruit trees, wheat, corns, vegetables and the like and is high-quality carbon-based biologicalfunctional fertilizer for producing green agricultural products, has a more remarkable comprehensive effect in greenhouse vegetable planting which cannot be subjected to crop rotation and especiallyhas the better continuous cropping resisting effect on the continuous cropping tobaccos on a mountain land.

Description

technical field [0001] The invention belongs to the technical field of agricultural resource development, and in particular relates to a continuous cropping tobacco root-improving enzyme carbon-based functional fertilizer and an application method thereof. Background technique [0002] The external conditions where tobacco grows include climate conditions, soil environment and cultivation management measures. The climatic conditions cannot be interfered by humans. Under the given climatic conditions, how to coordinate the interaction between tobacco and soil through cultivation measures is the key to determine the growth of crops. The so-called "deep roots can make leaves luxuriant", the root system is a fixation organ, an absorption organ, and an important synthetic organ, and its growth directly determines the growth and development of the aboveground part and the formation of yield. The impact of the soil environment on the tobacco root system mainly comes from three asp...

Problems solved by technology

However, because biochar itself does not contain organic matter, its carbon activity is too stable, and the carbon source that soil microorganisms can use is limited. In addition to improving soil physical properties, there is basically no nutrient supply and no obvious effect of promoting root growth.

Another study has shown that by adding exogenous active substances to fertilizers, soil nutrients can be effectively activated without affecting the composition of soil microorganisms. Under the same conditions, the rapid growth of roots can be further promoted, but the roots cannot break through the original physical limitations.
