Villager Wang Dacheng of Xinpo County, Xinxiang County asked: Last year, sweet potatoes were replanted after harvesting. However, 60 days after sowing, the roots of the crop were found to be vigorous and developed, but the growth of the aboveground parts was slow. Why is that?
A: Last year, sweet potato was planted on this plot. In order to ensure high yield, paclobutrazol may be sprayed in large quantities. Paclobutrazol is an endogenous inhibitor of gibberellin synthesis. Paclobutrazol residues in the soil for a long time, normal temperature (20 °C) storage stability for more than two years, so the slow growth of crops should be paclobutrazol phytotoxicity. Suggestions: 1. Spray plant growth regulators such as gibberellins, brassinolide, etc. 2. Spray foliar fertilizer, pay attention to spraying time before 10 o'clock in the morning and after 4 o'clock in the afternoon, and spray twice at low concentration. 3. A lot of water, reduce the concentration of paclobutrazol in the soil. 4. Apply topdressing nitrogen fertilizer to promote normal crop growth.
