The invention belongs to the field of nano material biological effect research, and discloses a magnesium-nitrogen-doped carbon dot, a preparation method thereof and application of the magnesium-nitrogen-doped carbon dot in improvement of plant photosynthesis. The preparation method comprises the following steps: dissolving citric acid, ethanolamine and magnesium hydroxide in ultrapure water, carrying out ultrasonic treatment, pouring the treated system into a reaction kettle, and conducting reacting at 200 DEG C for 6 hours; after the reaction is finished, conducting cooling to room temperature, filtering a product by using a filter head with the pore diameter of 0.22 [mu]m, and then conducting dialyzing for 12 hours; and conducting freeze-drying to obtain the magnesium-nitrogen doped carbon dots. After the carbon dots are compounded with chloroplast, the excitation energy can be absorbed by the chloroplast for photosynthesis, so that the photosynthetic activity is improved. After the carbon dots are applied to rice plants through foliage spraying, Mg,N-CDs can be uniformly distributed in leaf cells, expression of related enzyme genes is regulated and controlled, synthesis and metabolism of chlorophyll in leaves are promoted, the activity of chlorophyll molecules is kept at a high level, and therefore the photosynthetic activity of the leaves is improved. Finally, the plant growth is obviously improved.

Drought region chili planting soil improvement agent and preparation method thereof

The invention discloses a drought region chili planting soil improvement agent and a preparation method thereof. The drought region chili planting soil improvement agent comprises the following raw material components: bentonite, kaolin, perlite, soybean cakes, turf, animal manure, straws and a nanometer titanium dioxide modified resin additive. The preparation method comprises the following steps: 1) mixing the bentonite and the kaolin, crushing the mixture, adding the perlite, and mixing and stirring to prepare a mixed matrix A; 2) mixing the soybean cake, the turf, the animal manure and thestraws, performing sealing fermentation, drying the fermentation material after fermentation, and crushing into particles for future use; 3) mixing and stirring the mixed matrix A in the step 1) andthe fermentation material particles in the step 2), slowly adding the nanometer titanium dioxide modified resin additive in the stirring process and preparing the drought region chili planting soil improvement agent after stirring uniformly. The soil improvement agent prepared according to the method can effectively improve the current situation of drought and barren soil, reduce water loss and improve the soil fertility, and is favorable for the growth of chili.

Method and chemical preparation for improving assimilation of wheat NH4<+> and increasing grain yield

The invention discloses a method and a chemical preparation for improving assimilation of wheat NH4<+> and increasing grain yield. Aiming to overcome the problem of over-high content of NH4<+> at different growth stages of wheat due to basal application and / or dressing of urea or excessive application of NH4<+>-N fertilizer, different chemical preparations are applied at different stages to improve assimilation of wheat NH4<+> so as to convert into protein and promote operation of vegetative organs of wheat in the filling stage, increase the grain yield, and achieve lodging resistance effect,thereby solving a series of problems caused by over-high content of NH4<+>. The chemical preparations include potassium nitrate, potassium silicate and calcium silicate broadcast or applied by furrowing to soil surface before the jointing of wheat; the preparation, containing potassium nitrate, potassium silicate and JA mother liquor, sprayed during the jointing stage; the preparation B, containing potassium nitrate, potassium silicate and calcium silicate and JA mother liquor, sprayed before the flowering season; the preparation, containing potassium nitrate, JA mother liquor and IAA mother liquor, sprayed at the beginning of the filling stage.

Low-titanium low-sulfur ferrochrome and production method thereof

The invention provides low-titanium low-sulfur ferrochrome and a production method thereof, and belongs to the technical field of ferrochrome. Chromite, coke, silica powder, lime powder, a titanium removal agent, a desulfurizing agent and a slag former are used as raw materials; the low-titanium and low-sulfur ferrochrome is obtained through oxygen blowing melting, titanium removal and desulfurization, carbon addition, dephosphorization and desulfurization, refining and continuous casting after chromite is pretreated. The final slag is controlled to be in a CaO-Al2O3-SiO2-MgO four-source slag type; the mass percent of TiO2 in the chromite is less than or equal to 0.5%, the mass percent of S is less than or equal to 0.2%, and the mass percent of P is less than or equal to 0.3%. The production process is simple, the production cost is obviously lower than that of the prior art, the smelting process technology is reasonable, an industrial submerged arc furnace is adopted for continuous smelting, the product state is good, components are stable, meanwhile, the content of undesirable impurities such as Ti, P and S in the ferrochrome alloy is obviously reduced, and the strength, toughness, ductility and abrasion resistance of the obtained product are all obviously improved.
