The invention discloses a chelated compound trace element fertilizer and a preparation method thereof. The chelated compound trace element fertilizer comprises the following components: EDTA chelated copper, EDTA chelated zinc, EDTA chelated iron, EDTA chelated Manganese, borax decahydrate and ammonium molybdate; Its preparation method comprises: the preparation of EDTA chelated copper, EDTA chelated zinc, EDTA chelated iron and EDTA chelated manganese, borax decahydrate and ammonium molybdate are purchased, and above-mentioned The raw materials are mixed, dried, pulverized and packaged to make finished products. The prepared trace element fertilizer can be sprayed or flushed, and has a good effect on improving various symptoms such as small leaves, yellow leaves, and poor growth of vegetables caused by the lack of trace elements.

The invention relates to a preparation method of geniposide food antiseptic and fresh-keeping materials. The method uses geniposide and copper sulfate as raw materials, that is, the copper sulfate solution is added dropwise to the geniposide solution, stirred while dropping, and the dropping is completed After that, let it cool and stand still, then take the supernatant and pass it through a silica gel column for purification, and the purified solution that flows out is concentrated and crystallized in a vacuum, and dried to obtain the finished geniposide food antiseptic and fresh-keeping material geniposide-copper (II) chelate. The present invention has the advantages: 1. Applying geniposide to the field of antiseptic and fresh-keeping of food expands the scope of use of geniposide, directly consumes more gardenia raw materials for agricultural materials, increases market demand for gardenia, and benefits gardenia sub-planter. 2. The geniposide food antiseptic and fresh-keeping material prepared by the method of the present invention can not only preserve food anti-corrosion and prolong the shelf life of food, but also meet the human body's demand for trace element copper.

The invention discloses a plant growth regulator applied to cut dianthus caryophyllus flowers and an application method thereof. The plant growth regulator applied to cut dianthus caryophyllus flowers is composed of a seedling stage dianthus caryophyllus plant growth regulator, a vegetative stage dianthus caryophyllus plant growth regulator and a flowering stage dianthus caryophyllus plant growth regulator. The seedling stage dianthus caryophyllus plant growth regulator contains compound sodium nitrophenolate and a fertilizer, the fertilizer comprises urea, phosphorus pentoxide, potassium oxide, magnesium oxide, borax, EDTA chelated copper, EDTA chelated iron, EDTA chelated zinc and bentonite. The vegetative stage regulator contains DA-6, compound sodium nitrophenolate and the fertilizer. The flowering stage regulator contains DA-6 and the fertilizer. Root-irrigation is adopted for application of the regulators of various stages. The plant growth regulator applied to cut dianthus caryophyllus flowers provided by the invention increases the root length, root fresh weight, stem diameter, leaf number, flower diameter and petal number of dianthus caryophyllus, improves the quality of cut dianthus caryophyllus flowers, and then further strengthens the commodity competitiveness of cut dianthus caryophyllus flowers.

The invention provides a preparation method of marine biological protein peptide copper chelate. The method comprises the following specific steps of: carrying out enzymolysis on sea fish processing leftovers through alkaline compound protease, and carrying out centrifugal filtration to obtain protein peptide solution; adjusting the pH value of the protein peptide solution, and adding soluble copper salt to carry out chelation reaction; and after the chelation reaction is finished, removing free copper ions in the obtained reaction solution through a nano-filtration system, carrying out triple-effect concentration on the filtrate, and carrying out high-temperature spray drying to obtain the marine biological protein peptide copper chelate. The prepared marine biological protein peptide copper chelate is high in copper chelation rate, and can remarkably strength the enzyme activity in the animals and improve the utilization rate of protein, fat and vitamins after being added into feeds, so as to improve the growth performance of the animals.
