Strengthening Management of Wheat Sowing to Promote Early Development

1, intertillage warming, promote seedling growth. Intertillage and compaction before winter can loosen soil moisture, crush soil, stabilize soil, improve ground temperature, eradicate weeds, and promote early emergence of seedlings. Intertillage can be combined with winter topdressing and winter irrigation to take advantage of moisture, first suppression after intertillage, wheat seedlings tiller field can be shallow intertillage, intertillage can not hurt roots and seedlings. In early spring, intertill for 1-2 times to keep warm, raise moisture and preserve moisture, prevent cold and freeze, so as to promote seedling growth.

2. Fertilization promotes tillering, increases ears and grains. Late sowing wheat fields are mostly prepared hastily, with little or no basal fertilizer application. Fertilizer should be supplemented in time after wheat seedlings begin to tiller, and seedling fertilizer and wax fertilizer should be applied skillfully. If there is no tillering before late sowing or insufficient spring population, fertilizer can be increased in spring. Generally, after the spring temperature rises, timely topdressing and irrigation will promote spring tillering and panicle formation. Topdressing should be balanced, and nitrogen, phosphorus, potassium and trace fertilizers should be applied together. Apply fertilizer by combining root application with foliar spraying to meet the needs of@#@245@#@for normal growth.

3. Control diseases and insect pests and stabilize grain weight. Late sowing wheat heading late, more diseases and insect pests, especially aphids occur for a long time, generally need to use 1-2 times more than normal sowing wheat. Combined with pest control, potassium dihydrogen phosphate, urea and other fertilizer solutions are added into the liquid medicine for mixed spraying, so as to enhance the ability of plants to resist natural disasters such as dry hot wind and ensure full grain filling.
