Prevention and control measures: In the more sandy soil, each squat should be treated with more decomposed chicken manure. If the soil appears acidification, a certain amount of lime should be used to avoid large-scale application of ammonium nitrogen fertilizer at one time, and appropriate irrigation. Ensure adequate moisture. If symptoms of calcium deficiency occur under conditions with good soil moisture, use a 0.1%-0.3% solution of calcium chloride or calcium nitrate solution for foliar spray, 2 or 3 times per week.
