The invention relates to the technical field of insect trapping, in particular to a castanea mollissima trapping device which comprises an insect trapping cover, a collector and a trapper. An insect inlet is formed in the lower end of the insect luring cover, an insect outlet is formed in the upper end of the insect luring cover, and when the insect luring cover is in a working state, one side of the insect inlet is fixed to the trunk in the circumferential direction, so that a channel allowing insects to enter is formed between the other side of the insect inlet and the trunk; a collecting space is formed in the collector, and the lower end of the collector covers the upper end of the insect trapping cover, so that a collecting groove for preventing insects from escaping is formed between the lower end of the collector and the upper end of the insect trapping cover; the luring device is located in the collecting space and comprises a main body part, spine-shaped protrusions are arranged on the outer wall of the main body part, so that the luring device is in a shape like a raw chestnut with thorns, the luring device is made of a dark red material, or a dark red material layer is arranged on the surface of the luring device. The method overcomes the defects that the existing physical and chemical prevention and control means easily influence the original ecological balance of the Chinese chestnuts and easily cause environmental pollution.

This utility model relates to the field of insect trapping technology, specifically a chestnut elephant trapping device, comprising: an insect-attracting cover, a collector, and a attractant; the insect-attracting cover has an insect inlet at its lower end and an insect outlet at its upper end. When in operation, one side of the insect inlet is fixed circumferentially to the tree trunk, creating a passage between the other side of the inlet and the trunk for insects to enter; the collector contains a collection space, with its lower end covering the upper end of the insect-attracting cover, forming a collection groove between the lower end of the collector and the upper end of the insect-attracting cover to prevent insect escape; the attractant is located within the collection space and includes a main body with spiked protrusions on its outer wall, giving the attractant a shape resembling a spiky chestnut. The attractant is made of a dark red material, or its surface is covered with a layer of dark red material. This utility model overcomes the shortcomings of existing physical and chemical control methods, which easily disrupt the original ecological balance of chestnut trees and lead to environmental pollution.

The invention provides an embryo rescue method for hybrid generations of chestnut plants and application of the embryo rescue method, and belongs to the technical field of plant breeding. According to the method, hybrid embryos obtained after hybridization pollination of the female parent Japanese chestnuts and the male parent Chinese chestnuts are subjected to in-vitro culture and rescue, the rescue success rate can be increased through the embryo rescue technology, and the abortion rate of interspecific filial generation embryos is effectively reduced. The invention further provides application of the embryo rescue method for the hybrid generation of the chestnut plants in hybrid breeding of the chestnut plants, a certain platform is provided for increasing germplasm resources of the chestnut plants, creating new varieties and transforming old varieties, and a certain theoretical basis is provided for screening the hybrid generation with excellent quality.

The utility model belongs to the technical field of agricultural pest control equipment, concretely relates to the pest -trapping type electric network insecticidal frame of chestnut insect prevention, including base, the base centre place slides and installs a threaded column up and down, the base top centre place fixedly installs an adjusting block, the adjusting block inner ring wall with threaded connection of threaded column outer wall, the threaded column top installs the moth -attracting lamp, and one electric shock net is fixedly connected outside the moth -attracting lamp. The utility model discloses through the base centre slide and install threaded column up and down, and with adjusting block threaded connection, realize through the rotation adjusting block to lift threaded column, and then flexible adjustment moth -attracting lamp and electric shock net's height, to adapt to the height of different chestnut trees and pest activity area, the moth -attracting lamp can attract pests, and the electric shock net can kill the pests close by with electric shock, the guide rail of top plate bottom and movable mounting frame, cooperate the movable ring and cleaning brush of installing frame rotation, and it is convenient to clean the electric shock net, keeps its work efficiency.

The application discloses a SSR marker combination for identifying Chinese chestnut, and belongs to the field of molecular markers and detection. The latest genome data of Chinese chestnut is used to develop a SSR marker combination covering 12 chromosomes of Chinese chestnut. The SSR marker combination has the advantages of stability and high polymorphism between varieties, and can be applied to variety identification and genetic relationship analysis of Chinese chestnut and other plants of the genus Castanea. The application provides a reference for the researches of genetic diversity, variety identification, genetic relationship analysis, good variety breeding and core germplasm resource construction of Chinese chestnut and plants of the genus Castanea.

The invention discloses a castanea mollissima shell removing and opening all-in-one machine and a use method thereof, and relates to the technical field of agricultural product processing, and the castanea mollissima shell removing and opening all-in-one machine comprises a shell removing device and an opening device, the Chinese chestnuts are dried through the conveying and drying assembly, the threshing rate is improved, the integrity of the Chinese chestnuts can be guaranteed to a greater extent while Chinese chestnut cattails are crushed through the cattail threshing rollers, the two rotating rollers rotate relatively at a certain differential speed, the Chinese chestnuts without cattails are ground and threshed, and the threshing efficiency is improved. After the chestnut thorn shells are crushed and separated from the chestnuts and the chestnut thorn shells leave the shell removing box, the chestnut thorn shells and the chestnut thorn shells are separated in the air under the action of wind blown out by the air blower due to different masses, the chestnut thorn shells fall into the thorn shell collecting box, and large and small chestnuts are selected through vibration of the grading screening assembly, so that the screening efficiency is improved; and the sorted Chinese chestnuts are quickly positioned and conveyed through the Chinese chestnut conveying assembly in the opening device, and are quickly opened through the opening assembly, so that the labor is greatly saved, and the working efficiency is improved.

The invention belongs to the field of separation, and particularly relates to Chinese chestnut inner shell-based biochar and a preparation method and electro-adsorption separation application thereof, the preparation method comprises the following steps: 1) stirring and mixing dried Chinese chestnut inner shells and ZnCl2 powder through a spheroidizing machine; 2) transferring the mixture into a tubular furnace for direct activation; and 3) treating the activated charcoal to obtain the chestnut inner shell based charcoal. The Chinese chestnut inner shell is naturally of an intrinsic layered structure, the microstructure of the Chinese chestnut inner shell is of a multi-layer stacked two-dimensional sheet structure, the naturally formed layered structure provides a rapid transmission channel for ions, and the ion migration resistance is remarkably reduced; after being treated as a raw material, the mesoporous proportion of the pore structure is remarkably improved, and the high mesoporous structure provides a high-flux diffusion path for ions and reduces mass transfer resistance.
