Plant nutrient containing oligosaccharide and organic silicon

Abstract

The invention relates to a plant nutrient containing oligosaccharide and organic silicon. The plant nutrient contains the following components based on the weight of the plant nutrient: 0.1-4% of oligosaccharide, 1-10% of humic acid, 0-50% of urea, 0-15% of potassium nitrate, 0-15% of potassium dihydrogen phosphate, 0-30% of dipotassium hydrogen phosphate, 0.1-5% of trace elements, 0.1-5% of plant growth regulator, 10-80% of organic silicon extract and the balance of water, wherein the organic silicon extract is prepared by the following steps: mixing 50-75% of rice husk, 0.5-1.5% of microbial agent and the balance of water based on the weight of the mixture, fermenting the mixture for 72 hours, then adding 20% (W / W) NaOH solution to extract at 95 DEG C for 6 hours, and filtering to remove residues after extraction so as to obtain the organic silicon extract, wherein the mass ratio of the fermented mixture to the NaOH solution is 4.0:1; and the microbial agent is a composite microbial agent of Bacillus subtilis, Bacillus laterosporus, and yeast in a weight ratio of (50-80):(0-50):(0-35).

Description

Technical field [0001] The invention relates to a foliar fertilizer for crops, in particular to a plant nutrient containing oligosaccharide organic silicon. Background technique [0002] Rice husk is one of the main by-products of grain processing, accounting for about 20% of the quality of rice. It is a renewable resource with large quantity, wide coverage and low price. my country has at least 360 million tons of rice husks every year. Rice husk contains many elements. The main component of rice husk ash is SiO 2 , It mainly exists in the form of biomineralization and amorphous state. The basic ingredients of rice husk after carbonization are carbon and silicon dioxide, without heavy metals, which provides conditions for the production and application of agricultural chemical products. However, the utilization of rice husk by people today is not scientific and reasonable, and the beneficial ingredients in rice husk cannot be fully utilized, resulting in waste. In nature, pl...
