Lodging is one of the main obstacles affecting wheat yield under high fertilizer and water conditions. In recent years, the popularization and application of plant growth regulators in wheat production has opened a new way to prevent lodging and promote yield increase, and is an important supporting technical measure for high yield and stable production of wheat.
Spraying paclobutrazol (PP333) at the beginning of wheat, spraying 30 kg per gram of paclobutrazol solution with concentration of 20010-6, can make the plant dwarf, enhance the lodging resistance, and can also treat wheat powdery mildew and increase the absorption and utilization of nitrogen.
The application of uniconazole, uniconazole, is a new and efficient plant growth regulator. In the jointing stage of wheat, it can prevent plant lodging under high-density, high-fertility conditions and has the effect of reducing infertility spikelets and increasing grain weight. In the trial, the wheat that was applied with uniconazole had an average yield increase of 15.4% compared with the control when no wind or lodging occurred. Application method: 1 kilogram before the jointing of wheat, 30 kg of sprayed uniconazole solution of 3010-6 ~ 4010-6.
The spraying of chlormequat on the wheat fields with large populations and strong growth rate, spraying 50 to 75 kg of Chlormequat solution 0.15% to 0.3% in the initial stage of jointing, can effectively inhibit internode elongation of wheat and make the plant dwarfed. The base is hard to prevent lodging; if it is mixed with 2,4-D butyl ester, it can also treat broadleaf weeds.
