Answer: Because of the lack of calcium in the soil, it causes water-stained lesions in tomatoes, and it is necessary to apply calcium fertilizer in time, combined with applying base fertilizer and applying superphosphate. In the emergency, 0.4% calcium chloride solution can be sprayed on the leaves, sprayed once a day, and sprayed continuously for 3 times. At the same time, keep the soil moist and keep the soil moisture content at about 70% of the maximum water capacity in the field.
