The invention discloses an endangered plant phoebe hainanensis identification and systematic monitoring method based on multi-source data fusion, and belongs to the technical field of endangered plant protection. According to the method, a potential distribution area is delineated through a species distribution model, individual accurate identification and filing are achieved through a multi-branch feature fusion model, multi-scale growth and microenvironment data are collected through Internet of Things nodes, and finally a'discovery-identification-monitoring-protection 'whole-process closed loop is formed through a unified data management platform. According to the method, phenological feature extraction, transfer learning modeling, man-machine collaborative verification and low-power-consumption Internet of Things monitoring technologies are adopted, and the problems that a traditional method is low in efficiency, insufficient in recognition precision and fragmented in monitoring are solved. According to the method, efficient discovery, accurate identification and long-term dynamic monitoring of the wild population of the phoebe hainanensis are achieved, scientific support is provided for protection decision making, and the method is convenient to operate and high in practicability and has protection value and application prospects.

The invention belongs to the technical field of plant genetic engineering, and discloses a machilus nanmu TPS synthetase gene MnTPS4 and application thereof. The Machilus davidii TPS synthetase gene MnTPS4 provided by the invention is a key gene for synthesis of (+)-Camphene / Borneol / Geraniol in plant genetic engineering, synthesis of (+)-Camphene / Borneol / Geraniol can be effectively regulated and controlled, expression protein of the Machilus davidii TPS synthetase gene MnTPS4 is applied to synthesis and preparation of (+)-Camphene / Borneol / Geraniol, and the Machilus davidii TPS synthetase gene MnTPS4 has important application value.

According to the machilus rubescens TPS synthetase gene MnTPS8 and the application thereof, the gene is obtained from machilus rubescens through cloning for the first time and has beta-Eudesmol and Geraniol synthesis functions, and a new gene resource is provided for functional diversity and evolution analysis of a terpene synthetase gene family. Recombinant protein coded by the MnTPS8 gene has a unique dual-catalysis function, GPP can be catalyzed to generate Geraniol, FPP can be catalyzed to generate beta-Eudesmol, and compared with a single-function gene, the synchronous production process of two high-value terpenoids is greatly simplified, and the production cost is reduced. When the gene is used for heterologous expression or transgenic plant cultivation, synchronous large-scale production of beta-Eudesmol and Geraniol can be realized, the yield limitation of natural extraction is broken through, and the gene has remarkable economic value and industrial application prospect.

The utility model relates to the field of cultivation devices, in particular to a cultivation device with an adjusting function for phoebe sheareri breeding, which comprises a cultivation box and an adjusting sealing assembly. The outer end of the cultivation box is provided with an adjusting sealing assembly used for adaptive adjustment according to the seedling raising mode. The adjusting sealing assembly comprises a fixed plate, a transparent sealing frame, a movable plate, a thermometer, a heating pipe and a storage plate. By adopting the transparent sealing frame, full irradiation of sunlight can be guaranteed in the sealed cultivation process, photosynthesis of phoebe sheareri seedlings is promoted, good growth conditions are provided for breeding of phoebe sheareri, meanwhile, ultraviolet rays in the sunlight have a sterilization effect, breeding of germs can be reduced, the risk that the phoebe sheareri seedlings suffer from diseases is reduced, and the phoebe sheareri seedlings are protected from being damaged. Secondly, the transparent sealing frame can be disassembled and assembled according to breeding requirements, switching between open-air cultivation and sealed cultivation is achieved, damage to seedling root systems is reduced, the device can better adapt to different growth stages of phoebe sheareri, and the breeding survival rate of phoebe sheareri is increased.

The application discloses a kind of under-forest machilus seed direct seeding seedling methods, it is related to direct seeding seedling technical field, the method uses the two-stage method seedling process of " under-forest direct seeding seedling + transplanting commodity seedling " to seedling.The specific steps include: seed soaking (using 35 DEG C-45 DEG C warm water constant temperature soaking 24 hours), sand sprouting (using special sprouting frame carries out indoor sprouting 30 days, keep river sand water content 30% to seed white rate reaches 80%), under-forest seedbed arrangement (selecting the sand loam land piece of pH 5.0, and applying base fertilizer and erecting arch membrane), sowing (spreading with the density of 250 gram / square meter, covering thin soil and pine needle), seedling period management and commodity seedling cultivation.The method effectively solves the existing machilus seedling propagation technology Weak, weak resistance, under-forest adaptability is poor and other problems, significantly improves seed germination rate, seedling rate and the performance of tuber after transplanting, provides high-quality seedling guarantee for the under-forest large-scale, efficient planting of machilus.

The invention relates to the technical field of prevention and treatment of medicinal plant diseases, in particular to a polygonatum kingianum leaf spot disease prevention and treatment agent and a prevention and treatment method, and provides the polygonatum kingianum leaf spot disease prevention and treatment agent which contains a machilus macrocarpa fruit ethanol extract. The machilus macrocarpa fruit ethanol extract has a remarkable inhibition effect on various pathogenic bacteria of the polygonatum kingianum leaf spot disease; field tests show that after the machilus macrocarpa fruit ethanol extract with the mass concentration of 800 mg / L is sprayed, the polygonatum kingianum leaf spot disease is effectively prevented and treated, the highest prevention and treatment effect reaches 80.04%, and theoretical basis and technical support are provided for sustainable prevention and control of polygonatum kingianum diseases.

The application belongs to the technical field of seedling culture and particularly relates to a seed germination and tissue culture and rapid propagation method of Phoebe sheareri. First, a seed germination method of Phoebe sheareri is provided, and the sterile seedlings are obtained by culturing the seeds of Phoebe sheareri in 1 / 2MS medium containing NAA and AC, so that the seed germination rate is increased to more than 95%, and the problems of great difficulty in seed storage, low seedling emergence rate and failure to meet the production demand of Phoebe sheareri are solved. Further, on the basis of the sterile seedlings obtained by the seed germination, a tissue culture and rapid propagation method of Phoebe sheareri is provided, different concentrations and types of growth hormones are added in different stages of adventitious bud induction culture, proliferation culture and rooting culture, so that the success rate of adventitious bud induction is more than 90%, the proliferation coefficient is more than 6.0, and the rooting rate is more than 96%, and the problem of easy browning of the explant induction culture is solved, and the survival rate and rapid propagation efficiency in the tissue culture and rapid propagation stage are greatly improved.
