Selection and use skills of seeder

1. Selection skills of seeder

One must be familiar with the type of sowing machinery. As far as wheat and corn seeders are concerned, there are many types of wheat seeders, wheat and corn dual-purpose seeders, single and double row corn fertilization hole seeders, and no-tillage seeders. Second, we must find the right seeding model. The selection of the model should consider the size of the sowing plot, soil quality, soil fertility, the requirements of the variety for sowing technology, and farmers' habits. Third, we must consider the matching of the purchased planter with the power machinery we own. Fourth, we must choose products produced by regular enterprises with good reputation, good use effect and good after-sales service. It is best to be a product listed in the National Agricultural Machinery Subsidy Catalogue. Fifth, it is necessary to purchase from local merchants with a certain sales history and production scale, so as to obtain the guarantee of enterprise reputation and service ability. Sixth, carefully select and check whether the purchased products have product qualification certificates, instruction manuals, "three guarantees certificates" and relevant technical documents. Pay attention to check the material of the seed and fertilizer discharger. According to the local soil characteristics, select the appropriate type of opener for the planter. When conducting a test run, it is necessary to pay attention to the performance of the machine tool and observe the appearance quality. Seventh, ask the dealer for the official purchase invoice.

2. Main points of preparation before sowing

One is to do a good job of maintenance before the operation of the machine tool. Familiar with the functions of the purchased seeder except for sowing, such as leveling, ditching, fertilization, suppression, and soil covering. For the newly purchased seeder, the maintenance work should be done according to the requirements of the instruction manual. The second is to make various adjustments. After the seeder is connected to the tractor, it must not be tilted. When working, the front and rear of the frame should be in a horizontal state; according to the regulations in the instruction manual and agronomic requirements, first adjust the sowing amount, and then adjust the rotary tillage, ditching, covering soil, and pressing wheels. Adjust the depth of the opener appropriately, and finally adjust the row spacing of the opener, and adjust the suspension level of the frame and the tightness of the transmission chain to a moderate level. Third, in order to ensure the quality of sowing, it is necessary to carry out open field exercises for different operating conditions and master the operation skills proficiently. The fourth is to be familiar with the working environment. Observe the trees, machine wells, river ditches, neighborhood boundaries, slopes, boundary piles, etc. in the field and the edge of the field to ensure the safety of man and machine. Fifth, sufficient wearing parts must be prepared when carrying out cross-region sowing operation services, so as to avoid delays in sowing due to damage to parts during operations in different places. Sixth, pay attention to adding seed fertilizers. Seventh, when working on large plots, the seeds and fertilizers should be placed in appropriate positions on the ground, and added in a timely manner, so as to avoid delays in adding seeds and fertilizers midway.

3. Operation points when sowing

One is that the seeder should speed up slowly when starting, and drop the seeder gently. When the opener enters the soil, the planter should not back up to avoid damage to the opener; when choosing a working route, it should be easy to add seeds and machinery to enter and exit; Pay attention to moving forward in a straight line at a constant speed. Generally, you can’t go fast or slow or stop halfway to avoid replaying or missing sowing. Do not make sharp turns and backslide during operations; the planter must be lifted, the power of the seed meter and fertilizer discharger must be cut off, and the markers and ditch openers must be raised when emptying the field and turning. The second is that the agricultural machinery operator should observe the operation status of the seeder at any time during operation, especially pay attention to whether the seed metering device is discharging seeds, whether the fertilizer discharger is discharging fertilizer, whether the seed feeding and fertilizer feeding pipes are blocked, and whether the seed box and fertilizer box are There are enough seeds and fertilizers. The third is that after sowing a crop, the seed box should be carefully cleaned to avoid seeding failure caused by mixed seeds. Fourth, after sowing, the fertilizer discharge box should be cleaned in time to prevent corrosion of the machine. Fifth, when sowing seeds with pesticides, the sowing personnel should wear gloves, masks, goggles and other protective tools; the remaining seeds after sowing should be disposed of in a timely manner to avoid polluting the environment and causing harm to humans and animals. Sixth, after sowing a certain area, it is necessary to pay attention to whether the connection between the various parts of the machine needs to be reinforced. Seventh, the seeds in the seed box shall not be less than 1/5 of the volume of the seed box during operation. When transporting or transferring the plot, the seed box shall not contain seeds, let alone other heavy objects.
