Wheat spring tube compression equipment selection and operation requirements
Spring is a key season for wheat growth and development, including important processes such as turning green wheat and jointing, and it is a critical period for the whole growth period of wheat. If the management measures are implemented in a timely manner, it can be used to control the growth of strong wheat seedlings. Earlier and stronger early, effectively increase production. Mechanized management techniques in spring and summer wheat fields mainly include wheat field repression, chemical fertilizer topdressing, pest and weed control, and field irrigation techniques. To do a good job of mechanized field management in spring wheat, the wheat field should be promptly suppressed.
Mechanized wheat field repression is based on the growth of wheat, soil moisture conditions, etc., and appropriate repression of the wheat fields with long growing wheat fields and the straw returned to the fields. The man-made damage to the main stems and large borers is inhibited by artificially damaging the aboveground part of the leafhoppers. The proliferation of barnyardgrass and the growth of roots in the underground area promote the control of wheat growth and increase the efficiency of water conservation.
1. Machine selection. According to the conditions of wheat sowing, growth, soil moisture and other conditions, according to agronomic requirements, choose the right equipment to suppress the wheat field. For barley fields, cylindrical roller should be chosen to match the breadth of the surface; for conservation tillage, the barrage roller should be the same as the furrow spacing. For the dry field wheat field, tractor power and wheel distance must be used. Supporting cylindrical roller to achieve better repression effect.
2. Working hours. The repression is usually carried out during the period from the beginning of wheat returning to the beginning of the crop and is to begin after 10 am on frost-free days. Overwintering wheat fields need to be suppressed 2-3 times, the interval between repression is generally 5-7 days, and the control is strong and strong, and lodging is prevented; in autumn, the wheat fields with extensive site preparation and lots of clods are quickly repressed in the early spring and the soil is set aside. Bridging the cracks, reducing water evaporation and avoiding cold air intrusion into the frostbite near the tillering festival; repression of the early spring wheat field in the dry land can promote the water in the lower layer of the soil to move upwards, and can play a role in lifting, protecting and repelling the drought.
3. Job requirements. Compression can be combined with slashing, and generally should be pressed after squatting, in order to achieve the Panasonic real, mention smashing, security and warming purposes. In order to maintain soil moisture, increase surface temperature, eliminate overwintering weeds, and actively manage wheatfield management in the late period. Especially for wheat fields where the population is small and individuals are weak, scratching should be used as the primary measure for management of early spring wheat. In addition, when watering or raining in the spring, we must also plan to draw in due course. When we make a plan, we must plan, draw, draw, draw, do not leave earthworms, refuse to press the seedlings, and do not leak weeds.锄 effect.
4. Repression considerations. The soil is not wetted so as not to cause compaction; there is no pressure on the frozen wheat fields so as not to damage the wheat seedlings; the saline-alkali wheat fields are not pressed to prevent soil compaction and affect soil ventilation. The jointed wheat field has not been pressed to avoid breaking the internodes, resulting in insufficient panicles. When working, the walking speed should be uniform and the soil should be compacted.
