Adopting scientific response measures during the sowing period of wheat can reduce the lodging in late growth stage.
First, choose the appropriate variety. Generally, the plant height is relatively short (less than 75 cm), the toughness of the stem is good, and the lodging resistance is strong.
Second, land leveling, balanced fertilization. Fine soil preparation, to achieve smooth drainage and irrigation; increase organic fertilizer, phosphate fertilizer, pay attention to the application of potassium fertilizer, supplement the trace elements, improve the flexibility of the straw.
Third, the appropriate period of cultivation and sowing. It is advisable to sow on October 5-15 to ensure that the effective accumulated temperature before winter reaches 550°C--650°C, creating favorable conditions for the cultivation of strong seedlings.
Fourth, rational dense planting. According to the variety of tillers and the ability to produce spikes, the appropriate sowing volume should be determined so as to avoid overgrowth caused by field groups.
