Post-Spring Wheat Field Management Technology

Loosening loosing soil This is an important measure to promote the early return of young wheat and robust growth. The loosening of topsoil improves the ventilation conditions of the soil, increases ground temperature and promotes root development. Because the capillary is cut off, the soil moisture in the lower layer can be prevented from rising, and it plays a role in keeping the earth.

Fertilizer to return green manure due to seedlings topdressing. For the 2 to 3 types of seedlings with weaker growing conditions before winter, or poorly fertile seedlings with early-stage seedlings that are poor in fertility, early application and heavy application of green manure should be applied. They can be grabbed when the surface begins to freeze. In general, 10-15 kg of DAP can be applied per acre.

Watering without pouring winter water before winter or winter irrigation early, return to green when the relatively dry wheat fields, can be appropriate early pouring back to Qingshui, but the amount of water should not be too large, but can not flood irrigation. Due to the early poured wheat fields, the underlying soil is not completely defrosted, and large water can easily cause flooding and rooting. The new roots cannot be developed, and development is delayed. It is easy to form “small old seedlings” and there is a risk of dead seedlings. Whenever the winter water is poured in a timely manner, wheat seedlings grow in a robust wheat field and can be returned to Qingshui in due course.

Weeding in wheat fields, wheat fields, chemical weeding, less labor, and high efficiency. Broad-leaved weed-based plots are selected for each mu of alum (36% flufenazone tribenuron-methyl) wettable powder 5-8g or 10% vetoxanone 10-12g or Maishida (45.9%) Fluoride octanoate) 30 to 40 g watered 30 kg watered stems and leaves spray; grass weeds re-transmission field, the main field of amygdalin should use 3% dimethyl sulfonyluron oil (Shima) 25~30ml/mu; in the field where Lolium multiflorum occurs mainly, 5% clodinafop-propargyl herbicide 80ml/mu, watered 30kg for stem and leaf spray; broadleaf weed and alfalfa Undergraduate weeds mixed with wheat, with 40% per acre fenacin dry suspension 2 grams plus adjuvant 10 grams + 3% methylsulfuron oil suspension 25 to 30 ml watered 30 kg, spraying stems and leaves. When using herbicides, be sure to dilute with fresh water and adopt a secondary dilution method. Mix thoroughly and spray at the same time. When spraying, be sure to make it even and not heavy or spray.
