Nutritional base fertilizer capable of supplying calcium for long term and preparation method of nutritional base fertilizer

Abstract

The invention discloses a nutritional base fertilizer capable of supplying calcium for a long term and a preparation method of the nutritional base fertilizer. The nutritional base fertilizer is prepared from the following raw materials in parts by weight: rice husk, a 20wt% NaOH solution, shell powder, straw powder, fertilizer calcium powder, phosphogypsum, citric acid, methyl abamectin, sheep manure balls, egg shell, soybean residue, soybean curb residue, an enzyme agent, fresh forage grass and a suitable amount of water; the raw materials are unified and are reutilized as waste; the raw materials are subjected to simple fermentation treatment, and are then subjected to ultrafine ball milling to form micro powder; finally, rice husk carbonized particles are added into the micro powder, and the carbonized particles in a dry state bare more micro-pores which are beneficial to inlay micro calcium, so that the calcium is not easy to loss in soil and is supplied for a long term; the calcium not only enriches the nutrition types of a crop product, and meanwhile, achieves a stress resistance effect in a crop growth process.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a nutrient base fertilizer which can supply calcium for a long time and a preparation method thereof. Background technique [0002] With the development of the economy, the use of chemical fertilizers in agriculture is increasing. However, the utilization rate of crops to chemical fertilizers is low, the utilization rate of N fertilizer is 30-35%, and the utilization rate of P fertilizer is 10-20%, which will inevitably cause environmental pollution of chemical fertilizers. The problems of soil structure destruction and soil fertility decline, as well as water eutrophication are irreversible. [0003] Silicon is one of the important elements necessary for the growth and development of crops. People are paying more and more attention to the research of silicon. The introduction of research has confirmed that silicon can enhance the stems of crops, resist lodging, ...
