The emergence of machine-assisted seedling planters increased the speed and quality of artificial sowing, reduced the amount of seed used, and reduced the use of seed by one-third. However, in actual use, some farmers have reported that the use of seeders is not very satisfactory. There are often phenomena such as non-stick grain sticking of seed sticking boards and vacancy in bred seedlings. According to investigations, most of the seeders used in the city are pendulum devices. Due to the incorrect user methods and methods, problems have arisen. Now we will sort out our own snacks for the reference of farmers' friends.
One, sticky seed board is not roughened.
For the first time, the smooth surface of the sticky board must be sanded with a sandpaper to make it rough and evenly stick to a layer of water. When the grinding force is even, and the viscose board has no leaks, stick the seed board with water, and polish it evenly on a layer of water.
Second, seed processing.
1. The pendulum seeding device is a kind of fine seeding device, which can save 1/3 of the seed use amount, but it also requires the seed to have a higher germination rate, so it is necessary to carry out seed selection and impurity removal to ensure that the germination rate is 90 %the above.
2. Seed Cui shoots 80% of the time it can be broken and white.
3. The seed of the Cui bud should be dried before sowing, so that the seed skin is dry and conducive to sowing.
4. When the minimum daily temperature is above 12°C, dry seeds (commonly known as dumb and sorghum) can be planted and the sowing effect is best. There are two points to pay attention to the sowing of dried seeds: one is to increase the temperature of the cover film, and the other is that the water in the dish should reach saturation.
Third, the correct use of A, B surface board.
1. There are 20 columns on the A surface, 1920 seed grooves, 24 rows on the B surface, and 2760 seed grooves. Ordinary hybrid rice in the city should be planted with B-side seedlings. When the seedlings are planted, the number of horizontal pickings is adjusted to 24 times, and vertical pickings are placed at 15 mm to guarantee 2-3 seedlings per hole.
2. Face A can be used for breeding of super hybrid rice. During the interplanting, the number of horizontal pickings is adjusted to 24 times, and vertical pickings are placed in the middle to ensure 1-2 seedlings per hole.
3. If common hybrid rice is sown on side A, the number of horizontal pickings can be adjusted to 20 times, vertical feeding can be adjusted to a maximum of 17 mm, and 2-3 seedlings per hole can also be guaranteed.
