The invention aims to disclose the low-protein type fattening pig feed which can effectively solve the technical problem that the growth performance is reduced due to insufficient protein supply of the existing low-protein daily ration to the fattening pigs by adopting the specific daily ration component proportion and combining with the specific nutritional index level, and the growth performance of the fattening pigs is improved by constructing a unique daily ration system. The feed effectively reduces the breeding cost, improves the profit margin of breeding enterprises, relieves the problem of protein resource shortage, can effectively reduce nitrogen emission and ammonia emission, improves the environmental quality of pig farms, has important significance for realizing sustainable development and environmental protection targets, and has wide application prospects. The application of the low-protein daily ration technology provided by the invention in the pig industry has wide development prospects and important strategic significance.

The present application belongs to the technical field of multifunctional textiles, and provides a biomass-based multifunctional flame-retardant textile and a preparation method thereof.Cotton fabric is dipped in a folic acid aqueous solution and dried, the folic acid-treated cotton fabric is dipped in an egg yolk aqueous solution and dried; the cotton fabric is alternately dipped in the folic acid aqueous solution and the egg yolk aqueous solution to obtain pretreated cotton fabric; the pretreated cotton fabric is dipped in a phytic acid aqueous solution and dried to obtain a biomass-based colored antibacterial and ultraviolet-resistant multifunctional flame-retardant textile.The present application uses a layer-by-layer self-assembly method to construct a folic acid / egg yolk / phytic acid coating on the surface of the cotton fabric, successfully prepares an antibacterial and ultraviolet-resistant multifunctional flame-retardant textile with good coloring effect, improves the added value of the textile, expands the application field of the textile, and has important practical application value and social significance.

The present invention discloses a box-type bamboo-concrete composite beam, comprising two vertically arranged and mutually parallel bamboo webs, a concrete top plate fixed to the top of the two bamboo webs, and a bamboo bottom plate fixed to the bottom of the two bamboo webs. The box-type composite beam of the present invention greatly improves the cross-sectional bending rigidity of the beam body, and gives full play to the excellent mechanical properties of concrete and bamboo. Concrete is compressed and bamboo is pulled, and the advantages of the two complement each other, with the characteristics of high bearing capacity and high rigidity. The box-type structure has better anti-overturning performance and stability. The angle steel connection can effectively avoid the problem of debonding failure between bamboo boards due to excessive slippage of the bamboo webs. All components are prefabricated components, which can realize assembly-type rapid construction and dismantling and reinstallation for reuse.

The present application relates to the field of artificial intelligence, and discloses a multi-modal large model artificial intelligence operation navigation system based on EdgeAI and AIGC, comprising the following steps: S1, multi-modal data fusion and decomposition processing. Collecting massive intraoperative images, multi-classifying according to the operation completion quality, and adding each modal data to form a unified formatted multi-modal intraoperative image database; S2, training the big data using the ONE-PEACE-SZYYv3 large model algorithm based on AIGC to realize the generation and suggestion of the key elements in the operation by the large model; S3, using the pruning distillation technology, deploying the large model for edge computing, and realizing the real-time guidance of the doctor to complete the operation quickly, safely and accurately in the offline network disconnected island environment. The present application can realize the real-time processing and analysis of the multi-modal data in the operation in the offline network disconnected edge computing environment. Finally, it helps the surgeon to complete each operation efficiently and accurately, so that each ordinary operation patient can obtain ideal treatment service.

The invention discloses a simulated ecological planting method for sowing radix bupleuri in northern grassland rainy seasons, and belongs to the technical field of radix bupleuri planting. Comprising the following steps: (1) selecting high-quality bupleurum seeds as a seed source material for planting, mixing with fine sand, and planting in degraded natural grassland; (2) covering the surface layers of the seeds with fine sand after sowing, and applying a base fertilizer; (3) carrying out topdressing in a seedling stage; (4) performing reviving investigation at the beginning of the second year, and finishing the simulated ecological seed radix bupleuri in the rainy season when the reviving rate reaches 60-80%; and if the green turning rate does not reach the standard, repeating the step (1). The method mainly solves the problems of low emergence rate, difficulty in field planting and survival of plants and the like after natural grassland radix bupleuri is sown in northern China. The method comprises the following steps of seed source selection, planting field selection, planting time selection, sowing treatment, field management and timely harvesting. Compared with traditional radix bupleuri planting, the method has the advantages that the emergence rate and yield of radix bupleuri can be effectively increased, and remarkable economic benefits and ecological benefits are achieved.
