The invention discloses a vitrification ultra-low temperature preservation method of flax seeds. The specific method steps are as follows: take dried fresh flax seeds, place them in a loading solution for 20 minutes at normal temperature, and then transfer them to a frozen container filled with a vitrification protective agent. In the storage tube, the cryopreservation tube was placed in a gradient cooling box, down to -30°C--60°C, and put into liquid nitrogen for ultra-low temperature preservation. Take out the cryopreservation tube from the liquid nitrogen. When the room temperature of flax seeds is greater than or equal to 20°C, thaw naturally. If it is less than 20°C, thaw quickly in a 30°C water bath for 1 minute, wash 2-3 times with water, and then grow directly. The invention has the advantages of simple process, convenient operation, stable genetic properties of the preserved flax seeds, a germination rate of 98.67% in a seed germination test, and long-term preservation of the flax seeds.

The invention discloses an aggregating device of a cane harvester. The aggregating device comprises an aggregating box, an aggregating box bearing frame, aggregating box dumping oil cylinders, a hoist oil cylinder and a door-shaped support. The door-shaped support comprises two sliding rails, two sliding rods and two lifting chains, the sliding rods are slidably connected in the sliding rails, a sprocket wheel rack is arranged on upper connecting rods of the sliding rods, two ends of the lifting chains are respectively connected with the aggregating box bearing frame and upper connecting rods of the sliding rails, two ends of the hoist oil cylinder are respectively connected with the tail portion of a rack and the upper connecting rods of the sliding rods, two ends of the aggregating box dumping oil cylinders are respectively hinged to the left side of the aggregating box bearing frame and a left side plate of the aggregating box, and the right side of the aggregating box bearing frame is movably connected with the middle of a base plate of the aggregating box. The aggregating device is compact in structure and stable in operation; requirements of dumping points different in height can be adapted during unloading, full-automatic aggregating, unloading and loading processes are realized, production efficiency is improved, and soil and cane heads are prevented from being compacted and crushed, so that next-year sugarcane germination rate is unaffected.

The invention discloses a cane harvester which comprises a machine frame, a walking mechanism, a cane supporting mechanism, a cutting device, a conveying mechanism, a waste discharging device, a material gathering device, a power mechanism, a hydraulic power system and corresponding control systems, wherein the material gathering device is mounted on the part, on the tail portion of the cane harvester, of the machine frame, the waste discharging device is arranged above the material gathering device, the material gathering device comprises a material gathering box, a material gathering box bearing frame, a material gathering box lifting mechanism and a material gathering box dumping oil cylinder, and the waste discharging device comprises a three-channel box body, an air blower waste discharging component, an overturning oil cylinder, a locking oil cylinder, a latch and a limiting pin. According to the cane harvester, the problem that dumping of the material gathering mechanism is limited by the waste discharging device is solved, integrated automatic harvesting is achieved, full-automatic material gathering, dumping and loading are achieved, production efficiency is improved, and the problems that a loading vehicle enters a cane filed to cause soil compaction and crane head damage and affect the germination rate of canes the next year are solved.

The invention belongs to the technical field of agricultural production plant growth regulators, and discloses a vigorous growth control medicament for strawberry plants. The effective components of the vigorous growth control medicament for strawberry plants are flumetralin and prohexadione calcium, a weight ratio of the flumetralin to the prohexadione calcium is 30:1 to 1:30, and the total weight of the two components is 5-80% of the weight of the vigorous growth control medicament for strawberry plants. The vigorous growth control medicament for strawberry plants can effectively control thevigorous growth of the strawberry plants in the seedling stage in order to promote bud differentiation and improve the disease resistance and the output. The vigorous growth control medicament for strawberry plants, obtained through compounding low-toxicity plant growth inhibitors having two different acting modes, can improve the vigorous growth control effect, effectively reduce the use amount,reduces the use cost, and improves the eating safety of strawberries.

The invention relates to the technical field of crop cultivation, in particular to a method for overwintering seedlings of peppers. The present invention comprises the following steps: (1) site selection and shed building; (2) seedbed excavation; (3) seedbed arrangement; (4) irrigation; (5) sowing; (6) covering with rice husk ash; (7) spraying water; (8) film covering and arching; (9) water management; (10) temperature management; (11) nutrient management; (12) pest control; (13) seedling collection. The overwintering seedling raising method of the present invention makes full use of the thermal stability and heat preservation of the soil layer and the high groundwater level moisturizing, no watering is required in the seedling raising process, and the appropriate humidity of the seedbed is maintained while reducing labor, reducing chilling damage and damage caused by excessive humidity. Diseases, at the same time, a variety of methods are used to prevent and control pests and diseases. In the process of pepper seedling cultivation, the rate of cold-damaged seedlings is only about 0.6%, and the incidence of diseases and insect pests is 0, which saves 38.3% of labor. The quality of the cultivated pepper seedlings is high. economic income.

The invention relates to the mechanical field, in particular to a novel seed sterilization box and a sterilization method. It includes a box body, on which a rotating shaft is rotatably installed through bearings, and there is a roller in the middle of the rotating shaft, and the inner side of the roller contains a baffle, and the outer shell contains a plurality of holes, which include a door that can be opened. There is a set of heating plates placed under the box, the top of the box contains ventilation holes, and there is a temperature control and adjustment box on the side of the box. The temperature control and adjustment box contains a motor, a temperature controller and a power supply The rotating shaft extends out of the box to connect to the power output shaft, and the power output shaft is connected to the motor. A temperature sensor is installed inside the box, and the temperature sensor is connected to the temperature controller. Turn on the power, set the temperature, so that the internal heating, the seeds are evenly heated during the rotation of the drum, and the temperature changes after high temperature; cool down, and take out the seeds. Compared with the prior art, the present invention adopting the above technical scheme has the following beneficial effects: more seeds can be processed, the heat is uniform, the germination rate is not affected, and the sterilization is thorough.
