What measures are there to prevent lodging?

The measures to prevent lodging include selecting varieties with strong stems, water and fertilizer tolerance and short stems with short internodes, determining suitable planting density, implementing scientific fertilizer and water management, cultivating strong seedlings and timely controlling pests and diseases. When necessary, plant growth regulators can be used to adjust internode length, plant height and plant type.

After lodging, pay attention to drainage when the soil moisture is high. If lodging occurs earlier, tall crops should be lifted up as soon as possible and management should be strengthened; For densely planted crops, it mainly depends on the role of stem node auxin to promote the lodging stem to grow backward at a certain node and restore its upright state. Generally, management measures are no longer taken for lodging in the late growth stage, because the yield is slightly reduced and plants are easily damaged and broken when working in the field.
