Preparation method of soil conditioner

The invention relates to an organic fertilizer giving consideration to crop nutrient needs and soil ecological improvement and a preparation method thereof. The fertilizer is prepared from the following main ingredients in parts by weight: 30-50 parts of cow dung, 25-35 parts of rabbit dung, 25-35 parts of mushroom dregs, 25-35 parts of peanut shell and 10-20 parts of humic acid. The main ingredients are composted and fermented before granulation and bagging to obtain the organic fertilizer. In the fertilizer provided by the invention, due to the relatively short fermentation period and reasonable proportioning, the fermented organic materials are thoroughly composted and are beneficial and harmless to the crops, the problem of soil hardening is effectively controlled, the gas permeability of the soil is improved, multiple elements are provided for the plant growth, the soil moisture and water preservation effects of the soil are enhanced, inorganic matters not decomposed in time in the soil are decomposed and reutilized, and the problems of single fertilizer composition and incomplete plant nutrients are solved.

Organic fertilizer giving consideration to crop nutrient needs and soil ecological improvement and preparation method thereof

The invention discloses a method for preparing a biologic humic acid fertilizer from livestock manure. The method for preparing the biologic humic acid fertilizer, provided by the invention, comprises the following steps of firstly, mixing biochar and a biologic humic acid bacteria additive to obtain a fermenting agent; secondly, mixing the fermenting agent, the livestock manure and a conditioner to obtain a mixture, and adjusting the water content and the carbon-nitrogen ratio of the mixture to obtain fermenting raw materials of the biologic humic acid fertilizer; thirdly, performing high-temperature aerobic zymolysis on the fermenting raw materials of the biologic humic acid fertilizer to obtain the biologic humic acid fertilizer. The production process for preparing the biologic humic acid fertilizer from the livestock manure is simple in flow and is low in production cost; main raw materials comprise agricultural organic wastes such as the biochar, the livestock manure and straws and the like, so the requirement on sustainable development of biologic humic acid fertilizer industries can be met.
