One Film And Ten Rows Onion Seeder

Fertilizing, ploughing, leveling and breaking up the soil to facilitate direct seeding is required before sowing. In order to prevent the growth of weeds, every 667 m 2 before sowing, spray the ground with 100 ~ 150 ml of 48% sebutylene cream, mix the soil 3 ~ 5 cm, and then cover with film. Use wide film seeder (mainly used for cotton wide film mulch seeding in Xinjiang) to spread film and punch holes. Choose 1.4m width mulching film, tiling, the distance between films is about 20cm, black weeding film can also be used. After 1 week of film mulching, when the ground temperature of 5 cm under the film reaches 5℃, it is the appropriate seeding period, sowing as early as possible in the suitable seeding period. When sowing, take artificial sowing according to the hole, according to the plant spacing of 12 cm, row spacing of 15 cm with wood holding the hole, the depth of 1 ~ 2 cm, each hole sowing seeds 2 ~ 3 seeds, and then with soil sealing hole, pressure plastic film. When sowing, we should pay attention to the film must be broken, the seed should be shallow, to prevent leakage sowing. In order to facilitate early emergence and germination neat, before sowing seeds can be soaked in cold water for 12 hours, out of the air until the hands are not sticky and then sow. Field seeding at the same time should also leave a small part of seedlings, in order to prepare a large number of seedlings when the replacement. After the emergence of seedlings should be put in time under the film seedlings out of the hole, and fine soil sealing. Thinning and replenishing seedlings were carried out at 3-4 leaf stage, and 1 plant was kept in each well. When thinning seedlings, use long and narrow sharp tools, dig them out with roots, soak the roots with root powder, and then plant them into the holes. It is better to bury the fibrous roots at a depth to ensure the whole seedlings. The optimal number of 2 seedlings per 667 m is 30 thousand to 40 thousand.

At present, Onions are planted on a large scale in foreign countries and in Xinjiang, China. In order to improve the efficiency of onion planting, reduce production costs and labor intensity, they changed the previous artificial planting mode of Onions. Instead, they used sowing machinery to conduct direct seeding, and completed the operations of film laying, seed planting and drip irrigation belt laying at one time.
