A spatio-temporal variation monitoring method for SPAD of winter wheat, relating to the technical field of crop monitoring. The monitoring method comprises: a multispectral sensor of an unmanned aerial vehicle acquiring canopy images of winter wheat in a heading stage, a flowering stage, and a late grain-filling stage; extracting from multispectral images spectral features based on the canopy reflectance of winter wheat and texture features based on a graylevel co-occurrence matrix; using a feature selection policy to preferably select sensitive remote-sensing features; and applying a feature fusion policy and an SVR algorithm to construct a winter-wheat SPAD estimation model. Spectral features combining a near-infrared band with other bands can fully capture the spectral difference in SPAD of winter wheat in a reproductive growth stage, and texture features in a red-light band and the near-infrared band are relatively sensitive to the SPAD of winter wheat. The stability and estimation accuracy of an SPAD model constructed by applying a feature selection policy and a feature fusion policy are both superior to those of a model applying a feature policy alone and a model not applying any policy.

A polypeptide and polypeptide composition for inhibiting helicobacter pylori from forming a biological membrane and eliminating a biological membrane formed by helicobacter pylori. The amino acid sequence of the polypeptide is represented by SEQ ID NO. 1, 6, 13, 15, or 21. The polypeptide has the effect of inhibiting helicobacter pylori from forming a biological membrane and eliminating a biological membrane formed by helicobacter pylori, and the polypeptide contains no amino acid residue degradable in a gastric acid environment in the presence of a protease and still maintains bioactivity in the gastric acid environment in the presence of the protease. The production of helicobacter pylori drug-resistant bacterial strains can be reduced, and the therapeutic effect of clinically used antibiotics is improved.

Disclosed are an efficient and environmentally-friendly fire extinguishing agent and a preparation method therefor. The preparation method comprises: thoroughly grinding and mixing sodium dihydrogen phosphate, ammonium hydrogencarbonate, and a pulverization aid; adding white carbon black, and thoroughly grinding and mixing the mixture; and adding silicone oil, stirring the same while heating, and maintaining a constant temperature for a period of time to obtain a silicone oil film-coated white carbon black fire extinguishing agent. The fire extinguishing agent prepared by the method has remarkably improved fire extinguishing performance and excellent fire extinguishing effects, with a fire extinguishing efficiency double that of conventional dry powder fire extinguishing agents or greater, and is superior to other fire extinguishing agents currently on the market in moisture proof, anti-caking, and anti-afterburning properties, and environmental friendliness. The fire extinguishing agent balances high fire extinguishing efficiency, a wide application range, environmental protection, and economic benefits, and has good market potential and development prospects.
