Rainwater-resistant fertilizer for plants in hill area and preparation method of rainwater-resistant fertilizer

Abstract

The invention discloses a rainwater-resistant fertilizer for plants in a hill area and a preparation method of the rainwater-resistant fertilizer. The rainwater-resistant fertilizer is prepared from the following raw materials in parts by weight: rice husk, a 20wt% NaOH solution, rice straw, charcoal, attapulgite micro powder, lotus pond sludge, peat, ammonium bicarbonate, trace elements, ferrous sulfate, potassium permanganate, bean cakes and a proper amount of water. The rainwater-resistant fertilizer is an organic fertilizer applicable to the hill area, the hill area has the characteristics of being rich but single in mineral element, relatively large in amount of stone grains, relatively large in soil porosity and rapid in decrease of fertilizer dosage after rainwater flashing, according to the characteristics, by adopting the fertilizer disclosed by the invention, organic components of soil can be increased, the added sludge, straw and peat are all beneficial to increase of soil density, water flow action can be reduced, a product obtained after the peat is decomposed is rich in humic acid component, the viscosity of the soil can be improved due to the indigenous compatibility of the humic acid components, an added rice husk carbonized product has a certain adsorption function, and thus loss of nutrient elements can be prevented.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a rain-proof fertilizer for planting in hilly areas and a preparation method thereof. Background technique [0002] With the development of economy, the use of chemical fertilizers in agriculture is increasing. The utilization rate of chemical fertilizers by crops 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 eutrophication of water bodies, are irreversible. [0003] Silicon is one of the important elements necessary for the growth and development of crops. People pay more and more attention to the research of silicon. The introduction of research has confirmed that silicon can enhance the sturdy stem of crop plants, resist lodging, improve disea...
