Lodging-resistant water-soluble fertilizer for paddy rice and method for preparing lodging-resistant water-soluble fertilizer

Abstract

The invention discloses a lodging-resistant water-soluble fertilizer for paddy rice and a method for preparing the lodging-resistant water-soluble fertilizer. The lodging-resistant water-soluble fertilizer comprises, by weight, rice husk, 20wt% NaOH solution, tobacco straw, coal ash, diatomaceous earth, aloe powder, biogas residues, ammonium bicarbonate, blast furnace coal slag, soybean meal, enzyme agents, industrial wastewater and an appropriate quantity of water. The lodging-resistant water-soluble fertilizer and the method have the advantages that the coal ash is easily available, is industrial waste, is easy to pollute environments if the coal ash is naturally discharged, and contains a large quantity of calcium oxide, properties of the biogas residues are quite similar to properties of the coal ash, the biogas residues are weakly alkaline after being thoroughly decomposed, contain large quantities of calcium, magnesium and silicon, are water-soluble and can be easily absorbed by crops, and accordingly the lodging-resistant water-soluble fertilizer is beneficial to improving the disease resistance and the lodging resistance of the paddy rice.

Description

technical field

[0001] The invention belongs to the technical field of fertilizers, and in particular relates to a rice lodging-resistant water-soluble fertilizer 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, improve disease re...
