The present application relates to the technical field of intelligent internet of things mechanical fertilization control, and particularly relates to a corn staged fertilization control method based on internet of things. First, the present application obtains various nutrient data, hyperspectral images and growth stages of corn plants; further, the present application fuses overall nutrient data and overall NDVI value in each corn region to obtain growth suitability; further, the present application obtains real-time growth influence coefficients of each plant pixel point according to time sequence fluctuation of growth suitability of the same corn region, in combination with differences between growth suitability of the corn region and adjacent corn regions, and area of the corn region; further, the present application analyzes fluctuation of the growth influence coefficients and spatial offset of the corn region, in combination with growth retardation of the corn plant, to obtain real-time growth interference accumulation coefficients; finally, the present application realizes precise control fertilization in a staged and regional manner according to all growth interference accumulation coefficients corresponding to each corn region in real time, in combination with low degree of each nutrient data.

The invention provides a multi-source data fused early risk screening method and system for growth retardation of children, and belongs to the technical field of medical information. The method comprises the following steps: acquiring a first predicted growth sequence and a second predicted growth sequence of a target child; performing compensation correction on the second predicted growth sequence based on the intergenerational compensation sequence to obtain a second corrected predicted growth sequence; performing fusion processing on the first predicted growth sequence and the second corrected predicted growth sequence, and establishing a target predicted growth sequence; and monitoring and acquiring a tracking and actually measured height sequence of the target child, performing comparative analysis on the tracking and actually measured height sequence and the target predicted growth sequence, and when the tracking and actually measured height sequence does not meet the target predicted growth sequence, generating a growth retardation early warning. The technical problem that early-stage growth retardation risks cannot be effectively identified due to insufficient early-warning accuracy caused by child growth prediction in the prior art is solved, and the technical effects of improving the child growth retardation risk prediction accuracy and realizing early-stage accurate early-warning are achieved.

The invention relates to the technical field of traditional Chinese medicines, and discloses a medicinal and edible homologous compound preparation for children as well as a preparation method and application thereof. The compound preparation is prepared from codonopsis pilosula, Chinese yam, lotus seeds, gordon euryale seeds, coix seeds, hyacinth beans, poria cocos, endothelium corneum gigeriae galli, hawthorn, rice sprouts, lily and red date pulp, all the raw materials are selected from medicinal and edible substances, and the compound preparation is safe and free of side effects; the preparation can be prepared into powder or a cake, and the preparation method comprises the steps of raw material treatment, stir-frying, crushing and sieving, mixing and sterilizing, packaging, cake preparation, cake preparation, forming and cutting, and drying. The compound preparation disclosed by the invention is based on the theory of'earth up to generate gold 'in traditional Chinese medicine, has the effects of invigorating spleen and tonifying lung, appetizing and helping digestion, clearing damp and soothing nerves and improving immunity, and is suitable for being eaten by 3-12-year-old children with weakness of spleen and stomach, slow growth and low immunity for a long time.

The present application provides a kind of piglet feed additive and preparation method thereof, belong to feed additive technical field.The piglet feed additive includes: periplaneta americana drug residue enzymatic hydrolysate, xylo-oligosaccharide, lactoferrin, hawthorn extract, astragalus polysaccharide, corn starch and vitamin C;The preparation method includes: periplaneta americana drug residue enzymatic hydrolysate, hawthorn extract, astragalus polysaccharide, corn starch, vitamin C are added into mixing machine according to weight fraction, stirring speed is controlled, and powder mixture is obtained by mixing;The powder mixture is sieved, and the agglomerate that is not mixed uniformly is removed, to obtain the finished product of piglet feed additive.Piglet feed additive aims to overcome the defects of prior art, realizes drug residue resource utilization, and solves the problems such as diarrhea, growth retardation, low immunity and other problems caused by immature digestive system and weaning stress of weaned piglets.The preparation method is simple and controllable, the product is natural and residue-free, and provides an environmentally friendly, efficient and practical feed additive for the pig industry.

The invention relates to the technical field of animal feed, in particular to a cattle and sheep weaning concentrate formula, which consists of the following components in percentage by weight: 50 to 85 percent of energy-protein base material, 10 to 40 percent of plant function formula, 2 to 8 percent of mineral supplement, 0.5 to 3 percent of microbial regulator and 0 to 0.5 percent of optional drug additive, the plant functional formula is prepared by compounding Chinese herbal medicines with the functions of tonifying spleen and promoting appetite, clearing away heat and toxic materials and tonifying according to the weight ratio of (3-5): (1-3): (2-4), and preferably, the ratio of red date powder to dandelion powder to astragalus membranaceus powder to liquorice powder to elm leaf powder is 2: 1.5: 2: 1: 1.5; traditional breeding experience and modern nutrition technology are integrated, the problems of reduced feed intake, dyspepsia, low immunity, growth retardation and the like of cattle and sheep in the weaning period are solved in a targeted manner through a multi-component synergistic effect, and the feed does not need to depend on antibiotics, is high in safety and low in cost and can be prepared into dry powder or granular feed for use.
