The mechanized direct seeding technology of rapeseed is a light and simple cultivation technique that directly uses rapeseed direct seeding machines to broadcast rape seed to Daejeon. It mainly includes sowing date and cornice selection, field finishing, base fertilizer application, variety selection and seed treatment, and implements. Preparation, sowing operations, field management, etc.
At present, there are two types of machinery used for live rapeseeds: drills and seeding machinery. The drilling machine representative model is the 2BG-6B seed drill, which is an improved model of the rice seed drill. The metering device is an outer groove wheel type metering device, and the row spacing is 30-60 cm, and the adjustable metering device is a rotary knife cutting device. Other Drilling (including on-demand) machinery is mainly the difference of seeding devices; cover seed machinery, which is usually done by manual sowing in the field, and then cover-soiled by the cover-seed machine, it can be regarded as removing the seed Equipment seed drill.
The rapeseed machinery can directly save the seedling raising and transplanting links, which can increase labor productivity, reduce labor intensity, ease labor conflicts, and help to achieve cost-effectiveness and stable production and high yield of rapeseed production.
1. Provincial holidays. Multiple processes for mechanical live broadcasting are completed at one time, reducing labor intensity and improving work efficiency. In the case of artificial transplanting of rapeseed, only about 4.5 working days per mu need to be used for seedling transplanting, and 10 to 12 acres can be planted in one day with mechanized live broadcast technology.
2. The effective use of light temperature conditions. Mechanical live broadcasting can complete large-area planting in the appropriate sowing period, fully utilize the effective light-temperature conditions from October to November, promote the growth of rapeseed, and obtain robust winter pre-emergence seedlings.
3. The uniform seeding under precise seeding and seeding, the consistent depth and shade, Miao Qi and Miaoquan, are conducive to the coordinated development of individuals and groups of rapeseed, reducing disease, and improving lodging resistance.
4. It facilitates mechanized harvesting. Mechanized live broadcast can inhibit the oil menu strain branching, dwarf plantlets, suitable for mechanical harvesting.
