The invention discloses a pneumatic type variable sowing system and method for agricultural materials. The system comprises a rack, a material containing box, a material variable control module, a pneumatic conveying module, a sowing bearing truss and a sowing device, wherein the rack is connected with a power chasis, the material containing box is arranged on the rack and connected with the material variable control module, and the material variable control module is connected with the sowing device installed on the sowing bearing truss through the pneumatic conveying module. The method includes the steps that agricultural materials enter from the material containing box, then, flow of the agricultural materials is controlled through the material variable control module, and next, the agricultural materials are conveyed to the sowing device through the pneumatic conveying module and sown to target operation areas of farmland by the sowing device. According to the pneumatic type variable sowing system and method for agricultural materials, the agricultural materials can be input in a variable mode in both the forward direction and the width direction of a machine unit, the utilization rate of agricultural resources can be improved, pollution to the environment can be reduced, meanwhile, the coverage range of one-time operation is wide, and operation efficiency is high.

The invention relates to a crystal seed stability detection method and detection system. The crystal seed stability detection method comprises the following steps: respectively measuring and calculating the stability of crystal seed systems at different time points in the aging process; mixing the crystal seed systems at different time points in the aging process with diluent, and detecting by using a turbidity meter so as to obtain turbidities of different time points; establishing a relationship table of the turbidities and the stability; preparing a crystal seed diluted liquid under same conditions of the crystal seed system and the diluent in the former aging process, performing on-line detection by using the turbidity meter so as to obtain an instant turbidity, and comparing according to the relationship table of the turbidities and the stability, thereby obtaining instant stability. The detection device comprises a container, a mixing device, the turbidity meter and the like applicable to the method. According to the detection method, as the corresponding relationship table of the turbidities and the stability is firstly established, the stability can be calculated according to the turbidities according to the relationship table, and thus the detection accuracy and the instantaneity can be remarkably improved.

The invention discloses a method for making artificial seeds of red maple, belonging to the technical field of artificial seeds. The production method involved in the present invention firstly puts the sterile Chinese red maple somatic embryos into the artificial endosperm on the ultra-clean workbench, mixes them evenly, and then sucks one propagule at a time with a straw and drops it into the artificial seed coat After ion exchange reaction for 15min, rinse with sterile water for 20min, terminate the reaction, pick up and dry to get red maple artificial seeds, and finally, use the transplanting substrate to transplant and refine the seedlings, keep the substrate moist, and the air humidity is 70% to 90% , spray water 4 to 5 times a day, and carry out indoor hardening and transplanting. The red maple artificial seed system prepared by the invention has good stability, is relatively simple to manufacture, and has a high seedling emergence rate. At the same time, Chinese red maple somatic embryos are used as propagules, and the resources used are novel.

The invention relates to the field of tobacco planting, in particular to a multifunctional tobacco sowing system. The multifunctional tobacco sowing system comprises a drive mechanism, a seedling culture tray fixing mechanism, a substrate tank, a substrate conveying mechanism, a substrate retaining door, a substrate discharge tank, a linkage mechanism, a seed storage mechanism, a sowing device anda frame, wherein the drive mechanism is connected to the lower end of the frame; the drive mechanism is in transmission connection with the seedling culture tray fixing mechanism; the seedling culture tray fixing mechanism is arranged on the frame in a slide fit manner; the substrate tank and the seed storage mechanism are respectively fixed at the front end and the rear end of the frame; the substrate conveying mechanism is rotatably connected into the substrate tank; the substrate retaining door is connected to the substrate tank and located at the rear end of the substrate conveying mechanism. The multifunctional tobacco sowing system has the advantages that seedling culture trays of different sizes can be fixed, soil filling and sowing can be performed on the holes of the seedling culture trays, and tobacco planting efficiency can be increased.

The invention relates to an air-assisted rice broadcast sower, which comprises a seeding system, an air conveying system and a seed case, wherein the seeding system comprises an outer groove wheel, a sleeve, an outer groove wheel shaft, a stirring shaft, a big gear wheel, a small gear wheel, a small baffle, a seed collector and a seeding pipe; the diameter of the outer groove wheel is 100mm; outer groove wheel grooves are uniformly arranged in the surface of the outer groove wheel along the axial direction; the cross section of each outer groove wheel groove is in a circular arc shape with the circular arc radius being 6.5mm; the air conveying system comprises a fan and an air conveying pipe. According to the air-assisted rice broadcast sower, the diameter of the outer groove wheel is large, and the volume of each outer groove wheel groove is large, so that large-width rice seed sowing can be met; a pleated pipe is adopted in the middle of the air conveying pipe, so that the functions of pressurization and uniform seed mixing can be realized; a nozzle adopts a flat-shaped sector structure with a tapered uniform cross section area, so that the sowing width of the seeds can be increased, and the seeds can be sowed uniformly; not only is the problem of high percent of damaged seed of the traditional outer groove wheel solved, but also the problems that the air-assisted seeding machine is heavy in weight, high in cost and the like are solved, and the operation efficiency is improved.
