Timely application of regulators to wheat boosts stress resistance and yield
1. Paclobutrazol. At the wheat jointing stage; spray 50 kg of a 200 ppm paclobutrazol solution per mu, which can dwarf the plants, enhance lodging resistance and drought resistance. It can also control powdery mildew and improve the plant's absorption and utilization of nitrogen. 2. Chlormequat. For wheat fields with large populations and vigorous growth, at the wheat jointing stage, use 40-50 kg of a 40-50 ppm solution made from 5% chlormequat aqueous solution per mu...
