The invention discloses a fertilizing method for realizing simultaneous enrichment of iron, zinc and selenium in corn kernels. Relates to the technical field of corn nutrient fertilization. Comprising the following steps: 1) applying a zinc fertilizer and an iron fertilizer; humic acid; organic fertilizer or farmyard manure; a calcium-magnesium-sulfur-silicon fertilizer; spraying fertilizer on leaf surfaces by an unmanned aerial vehicle. According to the method, through reasonable fertilization, namely reasonable matching of large, medium and trace elements (carbon, nitrogen, phosphorus, iron, zinc, selenium and the like), the yield of corn kernels and the simultaneous improvement of iron, zinc and selenium in the kernels are achieved in calcareous calcareous alkaline soil, saline-alkali soil and light soil, and the contradiction between high yield and nutrient quality of the trace elements is solved.

The application belongs to the technical field of plant growth regulators, and particularly relates to application of mesoporous nano-silica loaded with Fe 2+ in regulating stem dwarfing of rice. When the mesoporous nano-silica loaded with Fe 2+ is applied in regulating stem dwarfing of rice, not only can the stem internode length of a high-stem variety be significantly shortened to reduce plant height, but also the stem thickness can be increased, and the effects of enhancing lodging resistance and optimizing stem material transportation are achieved; in addition, the Fe and Zn contents in brown rice can be significantly increased within a safe edible range, and the effect of trace element nutrition strengthening is achieved.

The invention relates to a method and a device for preparing complete cattle feed from double-cropping biological sugarcane. Comprising the following steps: S10, feeding first biological sugarcane into a five-roller squeezer for squeezing, using a small part of squeezed sugarcane juice for preparing lactic acid bacteria acidic fermentation liquor, and using the rest sugarcane juice for preparing syrup; s20, crushing the squeezed bagasse, feeding the crushed bagasse into a reaction tank, and carrying out an ammonia leaching-steam explosion pretreatment process; s30, a compound microbial agent, the pretreated bagasse and the crushed sugarcane leaves are fed into a bioreactor to be fermented for 15-20 days, and the bagasse and the sugarcane leaves rich in mycoprotein and various nutrient substances are obtained; and S40, mixing the fermented bagasse and sugarcane leaves with a compound trace element nutritional agent, a compound vitamin nutritional agent, oil bran, protein mulberry, table salt, corn, sodium bicarbonate, seaweed enzymatic hydrolysate and molasses to obtain the complete cattle feed. The problems that feed prepared from bagasse is poor in palatability and unbalanced in nutritional ingredients, and protein feed is high in cost can be solved.

The application discloses a sucrose complex zinc-iron-copper-manganese composite premix feed additive and a preparation method thereof, and belongs to the technical field of feed additives. The product is prepared by using sucrose as an organic ligand, and then performing step-by-step complexing reaction on zinc, iron, copper and manganese to form active complex components, and then mixing the active complex components with a carrier and / or an auxiliary material for feed additives to form the composite premix feed additive. A 1 wt% aqueous solution of the product is clear or substantially clear, and the proportion of ferrous iron in total iron is not less than 0.75. The preparation method is performed in the order of preferential addition of ferrous salt and last addition of copper salt, and an antioxidant is used to inhibit oxidation of ferrous iron, and the pH of the system is monitored and controlled in real time. The raw materials of the application have a wide source and low cost, and are suitable for comprehensive utilization of molasses resources in sugarcane production areas. The product has good stability and is not easy to absorb moisture and form lumps, and can be directly applied to feed production to provide various organic state trace element nutrients for livestock and poultry.

The invention discloses an application method of medium and trace nutrient elements for wrapper hydroponic system. The application method includes the following steps: providing a nutrient solution cultivation system as well as medium and trace element nutrient solutions for facility-based cultivation of wrapper; the medium and trace element nutrient solutions are applied in the cultivation of wrapper; wherein the medium and trace element nutrient solutions contain modulated components, 65-420 ug / L boric acid and 230-1600 ug / L manganese salt, the modulated components contain at least two of 310-690 mg / L calcium salt, 400-1300 mg / L magnesium salt and 40-250 mg / L ferric salt. The present invention can obviously improve yield, appearance quality and leaf tensile force of the wrapper by applying the nutrient solution with specific components in different stage of the wrapper cultivation, respectively, thereby greatly improving the industrial availability of the wrapper raw materials.

The invention provides a medicinal and edible organic selenium compound trace element nutritional oral liquid and a preparation method thereof, the oral liquid is prepared by taking a plurality of medicinal and edible traditional Chinese medicines as the basis, matching with compound trace elements and plant peptides, and performing multi-step extraction and accurate blending with specific hydrogen-rich water. The product has the effects of clearing away heat and toxic materials and nourishing yin and moistening lung of traditional Chinese medicines, has the dual functions of protecting liver by selenium and zinc and enhancing immunity by plant peptide and hydrogen element, is free of harmful chemical additives, high in safety and strong in stability, and solves the problem that the existing product cannot synchronously provide nutrients of organic selenium, hydrogen, strontium and titanium elements and plant peptide; the traditional Chinese medicine composition is suitable for fatigue recovery in sports or replacement of strong wine, can fill the market blank, and has popularization value.
