Gucheng County is a large county of rapeseed production, with a rapeseed planting area of 77,000 acres, of which the area of seed rape production is more than 10,000 acres, which can greatly improve the efficiency of rapeseed planting by reducing the loss of mechanized harvesting of rapeseed. A few days ago, the 2024 Xiangyang rape machine loss reduction and monitoring demonstration was held in Miaotan Town, Gucheng County.
In a rape field in Saonjiaoshu Village, Miaotan Town, a combine harvester shuttles back and forth in the field, accompanied by the roar of the machine, rows of rape are rolled into the harvester for threshing, and the straw is evenly discharged from the tail of the machine and returned to the field after crushing.
Compared with wheat, rice and other grain crops, it is more difficult to harvest and the loss rate is higher. In view of this feature, experts demonstrated the correct rapeseed harvesting operation specifications and introduced in detail the technical essentials of mechanized rape loss reduction harvesting:
1. From the planting process, it is necessary to choose rapeseed varieties that are easy to harvest, and it is recommended to choose high-yield and high-quality varieties with semi-dwarf stalks, compact, lodging resistance and crack angle resistance;
2. It is necessary to choose the appropriate rapeseed harvesting method according to local conditions, and it is recommended to concentrate on continuous planting and grow well in medium and high-yield fields. Segmented harvesting is adopted for yields of more than 300 kg to improve yield and quality, and reduce harvest losses; For small areas of scattered planting, it is recommended to use one-stage harvesting to reduce the harvesting links and reduce the harvesting cost.
3. It is necessary to carry out correct debugging of rape harvesting machinery, and try to increase the speed of the drum to reduce the threshing gap under the condition that the impurity content does not exceed the standard.
4. It is necessary to standardize the safe operation, so as to achieve "three cuts" and "three non-cuts", that is, cut with dew in the morning, cut on cloudy days, and cut in the evening; Do not cut after the dew dries, do not cut at high temperature at noon, and do not cut on rainy days.
In the activity, an agricultural machinery assembly and manufacturing enterprise in Luoyang used a grain and oil crop harvest loss detection device to detect grain loss on freshly harvested rapeseed. Through the test, the operation quality evaluation of the grain harvester can be obtained, and then the relevant parameters of the harvester can be adjusted through the data to achieve the purpose of reducing food loss.
