BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 The present invention is a flowchart of a method for precision sowing and cultivation of millet in one embodiment of the present invention. DETAILED DESCRIPTION

[0021] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Please refer to Figure 1 , Figure 1 The present invention is a flowchart of a method for precision sowing and cultivation of millet in one embodiment of the present invention.

[0023] The present invention provides a precision sowing and cultivation method for millet, which is suitable for precision planting of millet in small-scale experimental fields or small-scale families, and is used to provide accurate research data for scientific research, or to save planting costs and reduce labor intensity for family planting.

[0024] In the present invention, the precision sowing and cultivation method of millet includes two steps, namely: 1. preparation work before planting; 2. specific planting operation.

[0025] In step one, the present invention needs to prepare a sowing solution containing millet seeds, and the sowing solution contains at least water and plant nutrients. In the traditional millet planting method, manual hand-throwing sowing is basically the main method, that is, the sowing operation is completed by manually grabbing dry seeds based on experience and hand feel. The present invention adopts the "liquid immersion" method to prepare a sowing solution for sowing, and the sowing solution is required to contain at least a certain proportion of millet seeds, water and plant nutrients. In terms of mass fraction, millet seeds account for 50% to 75% of the total mass of the sowing solution.

[0026] Before mixing millet seeds into the sowing solution, first measure the density of this batch of millet seeds. Then, the density of the sowing solution was prepared according to the density of the millet seeds in this batch measured. in The value range is Specifically, the present invention first needs to measure the density of millet seeds. The specific measurement method is: the diameter of millet seeds is small (that is, the particle size of millet seeds is small), therefore, the weight (w1) of a certain volume (v1) of millet seeds can be obtained, and then the density of millet seeds can be calculated. in

[0027] After obtaining the density of millet seeds, the present invention configures the sowing solution according to the density of millet seeds. When configuring the sowing solution, the boiled rice soup is used as the accumulating liquid, and then clear water is added to the accumulating liquid until the density of the rice soup is less than Then add the plant nutrient and adjust the density of the sowing solution through the density regulator. Specifically, the present invention first cooks the rice soup (rice soup), and then after the rice soup is cooled to room temperature, add other additives to the rice soup, such as liquid plant nutrient (the liquid plant nutrient is added according to the maximum dosage indicated in the instruction manual of the nutrient, because water needs to be added to the sowing solution for dilution later), slow-release granular fertilizer, etc., and after all other additives are added to the rice soup, the density of the rice soup must be greater than the density of the millet seeds, and then add water to dilute the rice soup mixed liquid until its density is the same as the density of the millet seeds. Specifically, a certain volume (v2) of rice soup mixture (the sowing solution before adding millet seeds) is weighed (w2), and then the density of the rice soup mixture is calculated. in To adjust the concentration of the rice soup mixture, water can be added to dilute the mixture until the concentration is The value range is 95% Then, a certain amount of millet seeds and rice soup mixed liquid is obtained according to a mass fraction meter (weighing and mixing the millet seeds and rice soup mixed liquid) or a volume fraction meter (obtaining and mixing a certain volume of millet seeds and rice soup mixed liquid), and then the millet seeds are added to the rice soup mixed liquid and stirred evenly to prepare the final sowing solution.

[0028] In the overall preparation process of the sowing solution, the present invention uses a measuring cup with a volume scale to obtain the volume parameter and an electronic scale to obtain the mass parameter. In addition, the rice soup is rice soup or brown rice soup, and the temperature of the rice soup does not reach 30°C during the solution configuration process. In the proportioning process, the present invention can directly dilute the rice soup mixed liquid to gradually dilute its density to the same density as the millet seed. During the dilution process, if the concentration of the rice soup mixed liquid is too low, the present invention can increase its concentration (density) by adding a density regulator to the rice soup mixed liquid. Specifically, the density regulator is any one or a mixture of any two or more of thick rice soup, mashed potatoes and agar.

[0029] In step 2, in each sowing operation, the sowing solution is quantitatively absorbed (the sowing solution is quantitatively absorbed using an apparatus capable of absorbing the solution) for sowing. Further, sowing is performed at a depth of 10cm-20cm below the plowed surface. Further, the sowing solution is absorbed by a straw device and then inserted into the soil for push-injection sowing. In order to ensure that the distribution of millet seeds in the sowing solution remains consistent, the sowing solution needs to be stirred once before sowing, and then during the sowing process, the sowing solution is stirred every 25 to 35 minutes.

[0030] Specifically, the straw device is a hydraulic straw device or a pneumatic straw device. Further, an insertion depth gauge is provided on the straw device.

[0031] When the above-mentioned millet precision sowing and cultivation method is used to sow millet, the present invention adopts a straw device. In the present invention, the specific structure of the straw device is as follows: it includes a device body, a piston is arranged in the device body, an injection port is arranged at one end of the device body, a conical sleeve is arranged on the outer side of the injection port, so that the injection port of the device body can be inserted into the soil, the length of the injection port is 15cm to 20cm, the conical sleeve is consistent with the length of the injection port, the conical sleeve is fixedly arranged on the injection port, and the conical sleeve is threadedly connected to the main body of the device body. A push rod is arranged on the other side of the device body, and the push rod is connected to the piston to drive the piston to move in the device body. A connecting pipe is connected to the outer wall of the device body near the injection port, and the connecting pipe is connected to the sowing bin, and the sowing bin is used to load the sowing solution. A stirring rod is arranged in the sowing bin, and the stirring rod is rotatably arranged in the sowing bin. A one-way valve is arranged on the injection port for one-way output of the sowing solution, and a one-way valve is arranged on the connecting pipe for one-way output of the sowing solution in the sowing bin. When in use, the sower can carry the sowing bin and hold the device tube body, and manually push and pull the push rod to inject the sowing solution into the device tube body and inject it from the device tube body into the soil. Based on the above structure, the present invention can also provide a power device, the straw device is installed on the power device, and the power device can also be provided with a driving system (for example, a mounting frame is provided, and the mounting frame can be arranged on the power device so as to move up and down), the straw device is installed on the driving system, and the driving system drives the straw device to be inserted into the soil or raised and reset.

[0032] Of course, the precision sowing and cultivation method of millet provided by the present invention can also be carried out by quantitatively loading sowing solution into other containers for precision sowing. Other containers can be long-handled ladles with fixed capacity.
