At present, Rizhao City's "three autumns" production has entered a critical period, the autumn harvest area exceeds 60% of the total area, and autumn farming and autumn work is also being carried out in an orderly manner. Agricultural experts remind farmers friends, according to the current weather conditions and soil moisture, this year's wheat autumn work should pay attention to grasp the three aspects.
The first is to apply fertilization to the whole land, and to carry out deep or rotary tillage according to local conditions. It is necessary to avoid single and large application of chemical fertilizers to cause soil compaction and soil fertility, pay attention to reasonable ratio of nitrogen, phosphorus, potassium and medium and trace elements, and carry out deep application of chemical fertilizers to improve fertilizer utilization. rate.
Dong Jiagui, the station manager of Rizhao Agricultural Technology Extension Station, should work hard to increase the application of organic fertilizers, including applying soil fertilizer, returning straw to the field, and applying commercial organic fertilizers to gradually improve soil permeability, increase soil effective fertilization capacity, and improve soil. Drought and flood protection levels.
The second thing is to pay attention to the quality of the seeding. For plots that are more harmful to underground pests, seed dressing or seed coating should be carried out, and then wheat should be planted in time.
Tungzhao City Agricultural Technology Extension Station Director Dong Jiagui strives for most of the land in the city to be sown in the suitable sowing period from October 5 to 15. After the sowing, it will be repressed in time, especially for the land that has been returned to the field, and suppressed after sowing. It is an effective measure to eliminate "suspension root seedlings".
Through field investigations, some people still have misunderstandings in terms of seeding volume. The variety used in this plot is “Jimou 22â€, and the amount of seeds per mu is more than 12 kg.
According to the characteristics of this variety and the current sowing time, this variety should be controlled at 7-8 kg per mu of land (planting amount). The large amount of seeding is likely to cause Wang Miao in the previous year, and the seedlings cause nutrient consumption, which is not conducive to the cultivation of strong seedlings.
Experts said that for this year's rice, buckwheat and other late-sown wheat fields, it should be planted after October 20th, and the "four supplements and one promotion" should be closed. (é›…æŸ)
