How to prevent late wheat lodging
Answer: Professor Dang Zhanping of Yangling Vocational and Technical College said that in addition to the selection of lodging-resistant varieties, plant growth regulators can be properly sprayed to prevent wheat lodging, but it also depends on the management of seedlings. (Mu) must be prevented and controlled, and appropriate groups of wheat fields (up to 900,000 stalks/mu or more) should also be prevented and controlled. For wheat fields with small groups and thick stalks, prevention and control are not required, but "one spray and three preventions" should be implemented.

The first is paclobutrazol. Spraying paclobutrazol during the emergence period of wheat, spraying paclobutrazol solution per acre can make plants dwarf, enhance lodging resistance, and can also cure wheat powdery mildew, and increase the nitrogen absorption and utilization rate of plants.
Followed by Uniconazole. Uniconazole is a new type of plant growth regulator, applied on wheat, can prevent plant lodging under high density, high fertilizer and water conditions, and has the effect of reducing infertile spikelets and increasing thousand-grain weight. According to the test, under the condition of no wind and no lodging, the wheat with Uniconazole increased the yield by an average of 15.4% than the control. Application method: 1 week before wheat jointing, spray 50 kg of Uniconazole solution of 30×10-6～40×10-6 per mu.
The third is chlormequat. Chlormequat for wheat fields with large populations and vigorous growth, spraying 0.15%～0.3% chlormequat solution 50～75 kg per mu at the initial stage of jointing can effectively inhibit the elongation of wheat internodes and make the plants dwarf. The base of the stem is thick. Hard, thereby preventing lodging.
Note: Plant growth regulators are a class of substances with similar physiological and biological effects to plants. They cannot be used in excess, or mixed casually, and cannot be used as a substitute for fertilizers.
