Recently, many vegetable farmers have reported that there are small cracks on some bitter melons in the shed, and the cracks are brown and dry, which affects the commercial nature of bitter gourd, and the cracks in the plants in the shed are severe, and the cracks in the upper part of the plant are heavier. . The author believes that this is a physiological breach. Due to the large temperature difference in the previous period, the accumulation of dry matter is much, and the melons grow fast. In the case of high temperature during the day and low temperature at night, the phenomenon of “tight skin†appears, and the growth speed inside and outside the melon strip is inconsistent, and cracks are prone to occur. Because these symptoms are similar to those of blight and anthracnose, it is important to distinguish between them. When the vine disease is harmful to the melon strip, there is a small dot with water immersion, which gradually turns into a yellow-brown sag, and a small black spot appears in the diseased part, and a crack occurs in the center of the diseased spot. When the anthracnose harms the melon, it is brown-yellow depression, and the lesion is dry or wet, and there is no crack. Since this is a physiological disease, vegetable farmers must take correct management measures to prevent it. First of all, be careful to spray. Recently, powdery mildew and other serious occurrences, and triazole drugs for controlling powdery mildew can hinder the development of bitter gourd epidermis and increase the degree of occurrence of cracks. Therefore, it is necessary to reduce the use of triazole agents, and spray the swelling hormone, cytokinin and the like to increase the epidermal activity. Secondly, strictly control the dramatic changes in the small indoor environment. This requires timely watering and fertilization according to soil moisture, and the supply of fertilizer and water should be uniform. In order to keep the ventilator well ventilated, do not blindly close the tuyere insulation. The suitable growth temperature of bitter gourd is 25-30 °C during the day and 15-20 °C during the night. Bitter melon grows fast under such temperature difference, so the size of the closing tuyere should be based on this.
