Problems solved by technology

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. Soil structure damage and soil fertility decline, as well as water eutrophication problems are irreversible

Embodiment 1

[0019] A rice lodging-resistant water-soluble fertilizer, characterized in that it is made of the following raw materials in parts by weight (Kg): rice husk 42, 20wt% NaOH solution 130, tobacco straw 30, fly ash 35, diatomite 25, aloe vera Powder 10, biogas residue 45, ammonium bicarbonate 15, blast furnace cinder 10, soybean cake 55, enzyme agent 1, industrial wastewater 30 and an appropriate amount of water.

[0020] A preparation method of rice lodging-resistant water-soluble fertilizer is characterized in that it comprises the following steps:

[0021] (1) First crush the rice husk, crush it into 10-20 mesh sieve particles, put it into a muffle furnace, heat it to a temperature of 600-800°C under airtight conditions, and continue carbonization for 6-8 hours to obtain a carbonized product;

[0022] (2) Mix the carbonization product described in (1) with 20wt% NaOH solution, put it into a reaction kettle, heat it to 100-120°C, and keep it warm for 4-5 hours to obtain a carbo...

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...
