Winter Wheat Spring Management 5 points

1. The cultivator plans to raise the temperature to ensure early warning. The cultivator not only has the effect of dismantling the compaction, warming and protecting the earthworms, and killing the grass, but also has the effect of promoting the growth of strong seedlings, strong seedlings and strong seedlings. The favorable timing for early spring planning is “the top of the lingering period”, at this time, the best protection effect is beneficial to the early rooting of wheat and the promotion of strong seedlings. 2. Scientific operations, timely pouring the first spring water. Pouring the first water in spring is the key to improving yields and reducing costs. For wheat fields with poor lyricism and wheat fields with low number of weak seedlings or total stalks, the first spring in spring must reach the stage of getting up earlier; for those with good nymphobia and strong seedlings and wheat fields, the first water time can be postponed and poured into the joints before pouring. Fertilizer for water; For the high-yielding wheat fields with large groups, the fertilizer and water should be controlled and then poured into the jointing stage. Top dressing with watering. General acres of urea recovery 20 to 25 kg, phosphate deficiency plots, can make up Mushi DAP 7.5 to 10 kg. 3. Second, three fertilizer, flexible control. The second and third fertilizers should be flexibly controlled according to the conditions of the seedlings, the lyrics, and the climatic conditions. The second water is carried out during the period of flag leafing in the booting, and topdressing with nitrogen fertilizer. The third water is carried out 10 to 15 days after the wheat flowering, and it is no longer topdressing and watering so as not to affect the quality. 4. Timely chemical weeding, chemical control down. Spring is a period of weeds, and we should seize the opportunity to prevent it in time. The wheat grass weeds in wheat fields in my county are mainly bromegrass, and should be taken from the jointing stage to the heading stage, uprooted, and taken out of the field for centralized destruction. Broad-leaved weeds mainly include Sophora japonica, Mesquite Chinensis, Amaranth, Maijiagong, Morning Glory, Gray vegetables, Porcupine, and so on. They should be treated with tribenuron-methyl or superstar spray before they get up. For large groups of wheat fields, paclobutrazol (40 grams per mu) or Zhuangfengan (30 to 40 milliliters per mu) is sprayed before the start of the crop until the jointing stage. 5. Do a good job of forecasting and timely control of pests and diseases. Wheat powdery mildew, rust, root rot, sheath blight, head blight, aphids, and midge are pests that are prone to occur in the middle and late stages of wheat growth. It should be promptly removed.
